APR Calculator

What is APR?

APR, or annual percentage rate, expresses a loan’s yearly cost as a rate. Unlike the note rate, APR includes certain prepaid finance charges, such as points and some closing costs. That makes it useful when you are comparing offers with different rates and fees.

This APR calculator uses your loan amount, interest rate, term and prepaid finance charges. It finds the rate at which payments on the loan amount after fees equal the actual scheduled payment. In effect, the fees reduce the amount you receive while the payment is based on the loan terms you entered.

Why APR matters

A lower interest rate does not always mean a lower-cost offer. A lender may pair a low note rate with points or other upfront charges. Another offer may have a higher note rate but lower fees. APR gives you a way to compare those costs together, rather than judging offers by the advertised rate alone.

Use APR when you are reviewing a mortgage or another loan and deciding which offer better fits your plans. Also look at the monthly payment, cash due at closing and the loan terms. APR is a comparison measure, not a replacement for reviewing the lender’s full estimate or deciding whether the payment fits your budget.

APR is most helpful when the offers cover the same loan amount and term, and when you expect to keep the loan for a similar period. If you sell, refinance or pay off a loan early, upfront charges may have less time to spread across your borrowing. Your actual cost may then differ from what APR suggests.

How to use this APR calculator

1. Enter the loan amount from the offer you want to assess.
2. Enter the stated interest rate, also called the note rate.
3. Enter the loan term in years.
4. Enter prepaid finance charges. Check the lender’s estimate for points and other charges that qualify as prepaid finance charges. If you are unsure whether a charge belongs, ask the lender how it treats that fee.
5. Select calculate and review the APR alongside the monthly payment, note rate, fees and loan amount.
6. Repeat for each offer using consistent terms and fee information. Check that you are comparing the same kind of loan and that you have entered each offer’s charges the same way.

How to read your APR result

The APR is the annual rate that accounts for the entered finance charges under the calculator’s method. Compare it with the note rate to see how much the fees affect the borrowing cost. A wider gap means the entered charges add more cost relative to the loan amount and terms.

Read the result with the other figures. The monthly payment shows the scheduled payment; fees paid upfront show cash costs at the start; and the note rate is the stated interest rate. APR does not tell you whether you can comfortably afford the payment, or whether every charge on a lender’s estimate is included. Confirm which fees count and compare the full loan terms before choosing.

How to lower your loan costs

1. 01

   Ask for an itemized fee estimate

   Ask the lender to identify points and other prepaid finance charges, and to explain which charges are included in its APR. Clear inputs make your comparison more useful.

2. 02

   Negotiate fees or points

   Ask whether the lender can reduce or remove a fee, or offer a different rate-and-points combination. Compare the revised APR, payment and cash due at closing before you decide.

3. 03

   Compare offers with matching terms

   Request quotes using the same loan amount and term. A different term or fee structure can make an APR comparison less direct, even when the headline rates look similar.

4. 04

   Consider how long you expect to keep the loan

   If you may sell, refinance or pay off the balance early, ask the lender how upfront charges affect your cost over that shorter period. Consider whether paying those charges makes sense for your plans.

Common APR mistakes

• Choosing by note rate alone

  A lower note rate can come with higher upfront fees. Compare APR and the cash you need at closing, not just the advertised rate.

• Entering the wrong fees

  Do not assume every closing cost is a prepaid finance charge. Check the estimate and ask the lender which charges belong in the calculation.

• Comparing offers with different terms

  APR comparisons work best when the loan amount and term match. If they differ, review the payment and total loan terms as well.

• Treating APR as your exact future cost

  APR reflects the inputs and method used in the calculation. A change in your plans, such as paying off the loan early, can change how much the upfront fees cost you in practice.
