how to calculate an amount to be financed

How to Calculate an Amount to Be Financed.

The full price of a major purchase such as a house, boat or car is rarely financed. Most lenders for these types of loans require a down payment of some sort, usually expressed as a percentage. Additionally, mortgage loans list a different figure, "amount financed," which does not include prepaid fees paid to the lender. Knowing how to calculate an amount to be financed will help you make informed consumer decisions.



Part 1 Calculating a Commercial Loan Amount to be Financed.

1. Determine the selling price. For a vehicle, boat, or another type of commercial loan purchase this will be the amount you agree to pay for your new acquisition. It does not include other aspects of the deal such as the trade-in allowance, fees, taxes, and other closing costs.

2. Subtract any net trade-in allowance. For auto or boat purchases, among others, a dealer may offer a trade-in allowance or credit for giving them your old car or boat when you buy a new one. The value of this item, or a credit provided by the dealer, is then subtracted from what you owe on your new purchase. The net trade-in allowance is found by subtracting the amount still owed on your trade from the trade-in allowance offered by the dealership.

If the trade-in is high enough, dealers don't typically require an extra payment, such as a down payment.

Some dealers may allow you to use the trade-in value of your old vehicle to cover the required down payment on a new one (assuming the old one holds enough value).

3. Account for any cash rebates that are applied to the purchase price of the item. Dealers may also offer cash rebates as a way to incentivize purchases. These cash rebates are simply subtracted from the purchase price at closing. They also do not need to be included in the amount to be financed. Rebates may be provided to certain buyers, like students or military veterans, or may be specific to certain vehicles.

4. Settle on a loan amount. The amount left after rebates and trade-ins is the the amount owed. This amount must be either paid in full or borrowed from a lender and paid off in installments over time. From here, you can calculate the down payment if the lender requires one. For example, a lender might require 10 or 20 percent down on your purchase. Your loan amount is then the amount remaining after the down payment is subtracted out.

5. Use the loan amount as your amount financed. "Amount financed" is a term that is specific to home loans. All other loans simply refer to the amount financed as the total amount of the loan provided to the borrower. For these types of loans, simply use the loan amount after the down payment as calculated in this part as your amount financed.



Part 2 Determining the Amount Financed for a Mortgage Loan.

1. Negotiate a price for the asset with the seller. For a home, this will be your accepted offer price. For example, you might talk a homeowner down to selling a property for $100,000.

2. Subtract any deposits. Home purchases may have required a "good faith" deposit. Other purchases may also require a deposit be made while bidding on or reserving the item. This deposit is typically paid upon submission of an offer to purchase. This money is then subtracted from the purchase price, as you have already paid it.

Deposits are either returned (depending upon terms) or converted into the down payment amount and/or closing costs.

For example, if you put in a $3,000 good faith deposit on a $100,000 home, you would subtract this from the $100,000 to get $97,000.

3. Finalize the loan amount. The portion of the original purchase price remaining after these deductions is your loan amount, assuming you are planning on financing the purchase. This amount must be borrowed from a lender and then repaid over a period of time per a loan agreement. The loan amount is the amount borrowed from the lender, not the amount that will eventually be repaid in total, which also includes interest expenses.

4. Deduct the down payment amount. The down payment is paid in full upon closing the sale. It is generally a percentage of the total purchase price and is designed to provide security for the lender in the event of default. Therefore, it is not included in the amount financed.

Many mortgage lenders require 20 percent down on a real estate transaction, although you may be able to secure an FHA-backed mortgage requiring as little as 5 percent down payment. A lower loan balance results in less interest expense and the possible requirement of mortgage insurance.

A lower downpayment is expected on government- guaranteed loans such as FHA or VA because the lender has recourse to the Federal government in the event of default.

For example, if you paid a 20 percent down payment on the $100,000 house purchase, which would be $20,000, you would subtract this from your total.

Your good faith deposit may be applied towards your down payment. This means that the loan amount would still be the purchase price minus the down payment, which is $80,000 in this case.

5. Understand how amount financed differs from the loan amount. "Amount financed" is a term set by the 1968 Truth in Lending Act to describe how much credit is provided to a borrower when they take out a home loan. It is calculated by subtracting prepaid fees and finance charges from the loan amount, since these fees are paid at closing simultaneously with the execution of the loan documents. This means that the amount financed is always less than the actual loan amount. The amount financed is provided to borrowers on the Truth in Lending Disclosure Statement, which is supplied after you apply for a home loan.

6. Add up prepaid fees. Prepaid fees are subtracted from the loan amount to arrive at the amount financed. These fees include prepaid points, homeowners association fees, mortgage insurance, and escrow company fees. They also include lender fees like underwriting fees, tax service, process fees, and prepaid interest. Add all of these fees up to arrive a total prepaid fees amount.

7. Subtract total prepaid fees from the loan amount. Subtract all of the prepaid fees from the loan amount to get your amount financed. This information will also be available on your Truth in Lending Disclosure Statement.[9]



Part 3 Using the Amount Financed.

1. Compare different lenders. If you have the amount financed for a mortgage loan, you can use this information to compare different lenders by looking at the associated fees and interest rates. This information is provided on the Truth in Lending Disclosure Statement, which is provided by all lenders to loan applicants. If you instead are financing another purchase, you can use your amount of financing required to apply to a variety of loans and look for the best combination of fees and interest rate.

2. Calculate the amount of interest you will pay. Your loan will likely be charged compound interest as you pay it off. Compound interest paid increases with the loan duration, the interest rate, and the compounding frequency (how often the compound interest is calculated each year). When you have the amount financed, you can use online interest calculators to determine how much interest you will pay on loans with different loan terms. A longer, higher-interest loan will end up costing you much more money in the long run than a shorter-term, low-interest loan.

For more information, see how to calculate interest payments.

3. Calculate loan payments. If you know how much you need to borrower (your loan amount), you can use this information to check for loan rates online. Check loan aggregator sites to find interest rates for the type and size of loan that you need. Then, input this information into an online loan calculator to figure out what your monthly payments might be. The Financial Industry Regulatory Authority (FINRA) provides a good calculator at http://apps.finra.org/Calcs/1/Loan.

4. Assess your ability to afford a purchase. Once you have an idea of the monthly loan payments, you can use this information to figure out how much you can afford to take out in a loan. Assess your ability to afford the loan by starting with your monthly after-tax income. Then, subtract any existing debt payments (mortgage, auto, etc.), monthly expenses like utilities and food, and savings or contributions to an emergency fund. The amount left is money that you can afford to pay towards a new loan's monthly payment.

Most financial planners suggest limiting house payments plus taxes and insurance to 25 to 28 percent of take-home income.

For example, if your household net income is $7,000 per month, your total outlay for housing should be no more than $1,960 per month.

5. Determine mortgage APR. Your actual mortgage annual percentage rate (APR) is calculated using your amount financed, rather than the loan amount. That is, your actual APR will be higher than the interest rate listed on your loan. To calculate your actual APR, find your monthly payment by using your stated interest rate, loan term, and loan amount and entering them into a loan calculator. Then, record your monthly payment and find a loan calculator that allows you to input your monthly payment, loan duration, and loan amount and receive an interest rate as the output. The output will be your actual APR.

Question : Gomez family has just purchased a $2,574.54 microcomputer. They made a down payment of $574.54. Through the store's installemnt plan, they have agreed to pay $121.00 per month for the next 18 months. What is the amount financed?

Answer : The amount financed is the portion of the purchase price paid for by the installment plan. In this case, it is the $2,574.54 (purchase price) - $574.54 (the down payment), which is $2,000. The amount to be financed does not include the interest paid during the plan, which will be $178.

Question : Selling Price: $258,900. Loan term: 30 months on 5.25% interest rate. Down payment: $64,7325. What will be the amount to be financed?

Answer : You will be financing the selling price plus any fees, minus the down payment.



Tips.

When shopping for real estate, be sure that your price range reflects your planned amount financed. You may be able to afford more or less, depending upon your savings and the amount of a down payment.

Warnings.

The purchase agreement used by many car dealerships is notoriously complicated and confusing. Be certain that you understand every line item in the agreement before signing it when buying a new or used vehicle.

How to Calculate Compound Interest

How to Calculate Compound Interest.

Compound interest is distinct from simple interest in that interest is earned both on the original investment (the principal) and the interest accumulated so far, rather than simply on the principal. Because of this, accounts with compound interest grow faster than those with simple interest. Additionally, the value will grow even faster if the interest is compounded multiple times per year. Compound interest is offered on a variety of investment products and also charged on certain types of loans, like credit card debt. Calculating how much an amount will grow under compound interest is simple with the right equations.

Part 1 Finding Annual Compound Interest.
1. Define annual compounding. The interest rate stated on your investment prospectus or loan agreement is an annual rate. If your car loan, for example, is a 6% loan, you pay 6% interest each year. Compounding once at the end of the year is the easiest calculation for compounding interest.
A debt may compound interest annually, monthly or even daily.
The more frequently your debt compounds, the faster you will accumulate interest.
You can look at compound interest from the investor or the debtor’s point of view. Frequent compounding means that the investor’s interest earnings will increase at a faster rate. It also means that the debtor will owe more interest while the debt is outstanding.
For example, a savings account may be compounded annually, while a pay-day loan can be compounded monthly or even weekly.
2. Calculate interest compounding annually for year one. Assume that you own a $1,000, 6% savings bond issued by the US Treasury. Treasury savings bonds pay out interest each year based on their interest rate and current value.
Interest paid in year 1 would be $60 ($1,000 multiplied by 6% = $60).
To calculate interest for year 2, you need to add the original principal amount to all interest earned to date. In this case, the principal for year 2 would be ($1,000 + $60 = $1,060). The value of the bond is now $1,060 and the interest payment will be calculated from this value.
3. Compute interest compounding for later years. To see the bigger impact of compound interest, compute interest for later years. As you move from year to year, the principal amount continues to grow.
Multiply the year 2 principal amount by the bond’s interest rate. ($1,060 X 6% = $63.60). The interest earned is higher by $3.60 ($63.60 - $60.00). That’s because the principal amount increased from $1,000 to $1,060.
For year 3, the principal amount is ($1,060 + $63.60 = $1,123.60). The interest earned in year 3 is $67.42. That amount is added to the principal balance for the year 4 calculation.
The longer a debt is outstanding, the bigger the impact of compounding interest. Outstanding means that the debt is still owed by the debtor.
Without compounding, the year 2 interest would simply be ($1,000 X 6% = $60). In fact, every year’s interest earned would be $60 if you did earn compound interest. This is known as simple interest.
4. Create an excel document to compute compound interest. It can be handy to visualize compound interest by creating a simple model in excel that shows the growth of your investment. Start by opening a document and labeling the top cell in columns A, B, and C "Year," "Value," and "Interest Earned," respectively.
Enter the years (0-5) in cells A2 to A7.
Enter your principal in cell B2. For example, imagine you are started with $1,000. Input 1000.
In cell B3, type "=B2*1.06" and press enter. This means that your interest is being compounded annually at 6% (0.06). Click on the lower right corner of cell B3 and drag the formula down to cell B7. The numbers will fill in appropriately.
Place a 0 in cell C2. In cell C3, type "=B3-B$2" and press enter. This should give you the difference between the values in cell B3 and B2, which represents the interest earned. Click on the lower right corner of cell C3 and drag the formula down to cell C7. The values will fill themselves in.
Continue this process to replicate the process for as many years as you want to track. You can also easily change values for principal and interest rate by altering the formulas used and cell contents.

Part 2 Calculating Compound Interest on Investments.
1. Learn the compound interest formula. The compound interest formula solves for the future value of the investment after set number of years. The formula itself is as follows: {\displaystyle FV=P(1+{\frac {i}{c}})^{n*c}}FV=P(1+{\frac  {i}{c}})^{{n*c}} The variables within the equation are defined as follows:
"FV" is the future value. This is the result of the calculation.
"P" is your principal.
"i" represents the annual interest rate.
"c" represents the compounding frequency (how many times the interest compounds each year).
"n" represents the number of years being measured.
2. Gather variables the compound interest formula. If interest compounds more often than annually, it is difficult to calculate the formula manually. You can use a compound interest formula for any calculation. To use the formula, you need to gather the following information.
Identify the principal of the investment. This is the original amount of your investment. This could be how much you deposited into the account or the original cost of the bond. For example, imagine your principal in an investment account is $5,000.
Locate the interest rate for the debt. The interest rate should be an annual amount, stated as a percentage of the principal. For example, a 3.45% interest rate on the $5,000 principal value.
In the calculation, the interest rate will have to be input as decimal. Convert it by dividing the interest rate by 100. In this example, this would be 3.45%/100 = 0.0345.
You also need to know how often the debt compounds. Typically, interest compounds annually, monthly or daily. For example, imagine that it compounds monthly. This means your compounding frequency ("c") would be input as 12.
Determine the length of time you want to measure. This could be a goal year for growth, like 5 or 10 years, or this maturity of a bond. The maturity date of a bond is the date that the principal amount of the debt is to be repaid. For the example, we use 2 years, so input 2.
3. Use the formula. Input your variables in the right places. Check again to make sure that you are inputting them correctly. Specifically, make sure that your interest rate is in decimal form and that you have used the right number for "c" (compounding frequency).
The example investment would be input as follows: {\displaystyle FV=\$5000(1+{\frac {0.0345}{12}})^{2*12}}FV=\$5000(1+{\frac  {0.0345}{12}})^{{2*12}}
Compute the exponent portion and the portion of the formula in parenthesis separately. This is a math concept called order of operations. You can learn more about the concept using this link: Apply the Order of Operations.
4. Finish the math computations in the formula. Simplify the problem by solving for the parts of the equation in parenthesis first, beginning with the fraction.
Divide the fraction within parentheses first. The result should be: {\displaystyle FV=\$5000(1+0.00288)^{2*12}}FV=\$5000(1+0.00288)^{{2*12}}
Add the numbers within parentheses. The result should be: {\displaystyle FV=\$5000(1.00288)^{2*12}}FV=\$5000(1.00288)^{{2*12}}
Solve the multiplication within the exponent (the last part above the closing parenthesis). The result should look like this: {\displaystyle FV=\$5000(1.00288)^{24}}FV=\$5000(1.00288)^{{24}}
Raise the number within the parentheses to the power of the exponent. This can be done on a calculator by entering the value in parentheses (1.00288 in the example) first, pressing the {\displaystyle x^{y}}x^{y} button, then entering the exponent (24 in this case) and pressing enter. The result in the example is {\displaystyle FV=\$5000(1.0715)}FV=\$5000(1.0715)
Finally, multiply the principal by the number in parentheses. The result in the example is $5,000*1.0715, or $5,357.50. This is the value of the account at the end of the two years.
5. Subtract the principal from your answer. This will give you the amount of interest earned.
Subtract the principal of $5,000 from the future value of $5357.50 to get $5,375.50-$5,000, or $357.50
You will earn $357.50 in interest over the two years.

Part 3 Calculating Compound Interest With Regular Payments.
1. Learn the formula. Compounding interest accounts can increase even faster if you make regular contributions to them, such as adding a monthly amount to a savings account. The formula is longer than that used to calculate compound interest without regular payments, but follows the same principles. The formula is as follows: {\displaystyle FV=P(1+{\frac {i}{c}})^{n*c}+{\frac {R((1+{\frac {i}{c}})^{n*c}-1)}{\frac {i}{c}}}}FV=P(1+{\frac  {i}{c}})^{{n*c}}+{\frac  {R((1+{\frac  {i}{c}})^{{n*c}}-1)}{{\frac  {i}{c}}}}[7]The variables within the equation are also the same as the previous equation, with one addition.
"P" is the principal.
"i" is the annual interest rate.
"c" is the compounding frequency and represents how many times the interest is compounded each year.
"n" is the number of years.
"R" is the amount of the monthly contribution.
2. Compile the necessary variables. To compute the future value of this type of account, you will need the principal (or present value) of the account, the annual interest rate, the compounding frequency, the number of years being measured, and the amount of your monthly contribution. This information should be in your investment agreement.
Be sure to convert the annual interest rate into a decimal. Do this by dividing the rate by 100. For example, using the above 3.45% interest rate, we would divide 3.45 by 100 to get 0.0345.
For compounding frequency, simply use the number of times per year that the interest compounds. This means annually is 1, monthly is 12, and daily is 365 (don't worry about leap years).
3. Input your variables. Continuing with the example from above, imagine that you decide to also contribute $100 per month to your account. This account, with a principal value of $5,000, compounds monthly and earns 3.45% annual interest. We will measure the growth of the account over two years.
The completed formula using this information is as follows: {\displaystyle FV=\$5,000(1+{\frac {0.0345}{12}})^{2*12}+{\frac {\$100((1+{\frac {0.0345}{12}})^{2*12}-1)}{\frac {0.0345}{12}}}}FV=\$5,000(1+{\frac  {0.0345}{12}})^{{2*12}}+{\frac  {\$100((1+{\frac  {0.0345}{12}})^{{2*12}}-1)}{{\frac  {0.0345}{12}}}}
4. Solve the equation. Again, remember to use the proper order of operations to do so. This means that you start by calculating the values inside of parentheses.
Solve for the fractions with parentheses first. This means dividing "i" by "c" in three places, all for the same result of 0.00288. The equation now looks like this: {\displaystyle FV=\$5,000(1+0.00288)^{2*12}+{\frac {\$100((1+0.00288)^{2*12}-1)}{0.00288}}}FV=\$5,000(1+0.00288)^{{2*12}}+{\frac  {\$100((1+0.00288)^{{2*12}}-1)}{0.00288}}
Solve the addition within the parentheses. This means adding the 1 to the result from the last part. This gives: {\displaystyle FV=\$5,000(1.00288)^{2*12}+{\frac {\$100((1.00288)^{2*12}-1)}{0.00288}}}FV=\$5,000(1.00288)^{{2*12}}+{\frac  {\$100((1.00288)^{{2*12}}-1)}{0.00288}}
Solve the multiplication within the exponents. This means multiplying the two numbers that are smaller and above the closing parentheses. In the example, this is 2*12 for a result of 24. This gives: {\displaystyle FV=\$5,000(1.00288)^{24}+{\frac {\$100((1.00288)^{24}-1)}{0.00288}}}FV=\$5,000(1.00288)^{{24}}+{\frac  {\$100((1.00288)^{{24}}-1)}{0.00288}}
Solve the exponents. This means raising the amount within parentheses to the result of the last step. On a calculator, this is done by entering the value in parentheses (1.00288 in the example), pressing the {\displaystyle x^{y}}x^{y} key, and then entering the exponent value (which is 24 here). This gives: {\displaystyle FV=\$5,000(1.0715)+{\frac {\$100(1.0715-1)}{0.00288}}}FV=\$5,000(1.0715)+{\frac  {\$100(1.0715-1)}{0.00288}}
Subtract. Subtract the one from the result of the last step in the right part of the equation (here 1.0715 minus 1). This gives: {\displaystyle FV=\$5,000(1.0715)+{\frac {\$100(0.0715)}{0.00288}}}FV=\$5,000(1.0715)+{\frac  {\$100(0.0715)}{0.00288}}
Multiply. This means multiplying the principal by the number is the first set of parentheses and the monthly contribution by the same number in parentheses. This gives: {\displaystyle FV=\$5,357.50+{\frac {\$7.15}{0.00288}}}FV=\$5,357.50+{\frac  {\$7.15}{0.00288}}
Divide the fraction. This gives {\displaystyle FV=\$5,357.50+\$2,482.64}FV=\$5,357.50+\$2,482.64
Add. Finally, add the two number to get the future value of the account. This gives $5,357.50 + $2,482.64, or $7,840.14. This is the value of the account after the two years.
5. Subtract the principal and payments. To find the interest earned, you have to subtract the amount of money you put into the account. This means adding the principal, $5,000, to the total value of contributions made, which is 24 contributions (2 years* 12 months/year) times the $100 you put in each month for a total of $2,400. The total is $5,000 plus $2,400, or $7,400. Subtracting $7,400 from the future value of $7,840.14, you get the amount of interest earned, which is $440.14.
6. Extend your calculation. To really see the benefit of compound interest, imagine that you continue adding money monthly to the same account for twenty years instead of two. In this case, your future value would be about $45,000, even though you will have only contributed $29,000, meaning that you will have earned $16,000 in interest.

FAQ.
Question : What does "to the power of" mean?
Answer : "To the power of" refers to a particular numerical exponent. It is a multiplication in which a number appears as a factor that many times. For example, 2 to the power of 1 equals 2. 2 to the power of 2 equals 2x2, or 4, and 2 to the power of 3 is 2 x 2 x 2, or 8.
Question : How do I find the compound interest on a 29,870 loan at 6% interest?
Answer : First take out the amount by the formulae: principle(1+ r/100) to the power n (number of years), then take out the ci by subtracting the principle from the amount.
Question : What do I type on a calculator to find compound interest?
Answer : Compound interest can be calculated in several ways. The most common is to say that A=Pe^(rt) where P is the initial amount, "e" is a constant around 2.71, "r" is the interest rate (i.e. 7% would be entered in as 0.07), "t" is the duration in which the interest is being calculated in years and "A" is the final amount.
Question : How do I know if it's better to owe interest on something or to pay a lump sum at no interest?
Answer : Cost/value analysis. Calculate the total you'll pay under both methods and find the difference. Then compare that difference to the value of buying now (with a loan) versus later (lump sum).
Question : How do I find the future value and the compound interest if £4000 is invested for 5 years at 42% p.a?
Answer : Principal=$4000, n=5, R=42%,0.42. The formula: FV=PV(1+r)r aise power n and substitute the value.
Question : How do I calculate principal in compound interest?
Answer : Principal = fv = p(1 + i/c)ⁿc. Formula for principal in compound interest (1 + R/100), where R = rate.

Tips.

You can also calculate compound interest easily using an online compound interest calculator. The US Government hosts a good one at https://www.investor.gov/tools/calculators/compound-interest-calculator.
A quick rule of thumb to find compound interest is the "rule of 72." Start by dividing 72 by the amount of the interest your are earning, for example 4%. In this case, this would be 72/4, or 18. This result, 18, is roughly the number of years it will take for your investment to double at the current interest rate. Keep in mind that the rule of 72 is just a quick approximation, not an exact result.[8]
You can also use these calculations to perform "what-if" calculations that can tell you how much you will earn with a given interest rate, principal, compounding frequency, or number of years.
