How APR Works on a Loan

APR can help you understand the possible yearly cost of borrowing, especially when a loan includes fees in addition to interest. Knowing how APR works can make it easier to compare loan options before you apply.

Quick answer

APR stands for annual percentage rate. It is a yearly percentage that can reflect both the interest rate and certain loan costs or fees. Because APR can include more than just interest, it may give borrowers a clearer way to compare loan offers.

What does APR mean?

APR is a way to describe the cost of borrowing money over one year. For many loans, it includes the interest rate plus certain fees that are part of the loan cost. This makes APR different from the interest rate alone.

For example, two loans may have the same interest rate, but one loan may charge a higher origination fee. In that situation, the loan with the higher fee may have a higher APR.

Why APR matters when comparing loans

APR matters because the lowest monthly payment is not always the lowest-cost loan. A longer loan term may lower the monthly payment but increase the total interest paid over time. A loan with fees may also cost more than it appears from the interest rate alone.

When comparing loan options, APR can help you look beyond the advertised rate and focus on the possible overall cost of borrowing.

Simple APR comparison example

Loan A

  • Loan amount: $10,000
  • Interest rate: 9.99%
  • Fees: $0
  • APR: 9.99%

Loan B

  • Loan amount: $10,000
  • Interest rate: 9.49%
  • Fees: $400
  • APR: may be higher than the interest rate

Loan B has a lower interest rate, but the added fee may increase the APR. That is why APR can be helpful when comparing multiple loan offers side by side.

Does APR change your monthly payment?

Your monthly payment is usually based on the loan amount, interest rate, and repayment term. APR can help show the broader cost of the loan, especially when fees are included. In some cases, fees may be deducted from the loan proceeds, financed into the loan, or paid separately.

Before comparing offers, check whether any fees are included in the loan balance or taken out before funds are sent to you.

Questions to ask before comparing APRs

  • Does the APR include an origination fee or other loan fees?
  • Is the rate fixed or variable?
  • What loan term is being used for the APR quote?
  • Are there prepayment penalties?
  • Will checking the rate affect my credit score?
  • How much will I pay in total over the full loan term?
