How To Calculate Interest To APR

Often times, lenders always made available the APR on your application of a loan. Most cases, only interest rate are given. Perhaps you only have interest rate but know that you’re paying more in fees, then get to know your APR value or percent. However, if you want to do that personally, use a spreadsheet formulas and online loan calculators to plug in the numbers that you know. To calculate your APR here is what you must know:

  • The total amount you intend to borrow
  • The interest rate of such loan
  • The repayment terms
  • The cost of any fees.

Here is how to put all your information together to turn your interest rate into your APR. Let’s assume you are borrowing $10,000 and you’ve been quoted an interest rate of 12%. You are paying closing fee of $500. The APR of your 2 year loan would be roughly 16.92%

Steps To Calculate APR

Step 1

Key in the following formula into any spreadsheet cell to calculate the monthly payment for your loan:

=PMT(Interest rate/months, total numbers of months you pay on the loan, loan value us fees)


Therefore your monthly payment would be $494.27

Step 2

After, you have gotten the monthly payment, let’s determine the APR 

=RATE(Total number of months you pay on the loan, your monthly payment shown as negative, and the current value if your loan) 

You can express it thus:


You will have a monthly rate of 0.0141.

Step 3 

Here to get you’ll have to multiply your monthly rate (0.0141) by 12 to get the annual rate

0.0141* 12 =0.1692

Your annual rate is = 0.1692

Step 4

Finally, to express your annual rate in percentage form, multiply by 100 to convert from a decimal point into a percentage 

0.1692 * 100 = 16.92%

Therefore your APR is 16.92%

Now that you have work out, your APR, you’ve seen that your original interest rate of 12% does not really reflect the actual rate you get when you consider the fees you’ll pay. Instead of 12% interest rate, you are going to pay.
