What is APR?

What the annual percentage rate actually measures, how it differs from the interest rate, and why it's the number to compare across offers.

APR stands for annual percentage rate. It's meant to represent the total yearly cost of borrowing, expressed as a percentage — combining the interest rate with certain fees, like an origination fee, so you can compare offers on a more even footing.

APR vs. interest rate

The interest rate reflects only the cost of borrowing the principal. The APR folds in additional costs required to get the loan, giving a fuller picture of what you'll actually pay. Two loans with the same interest rate can have different APRs if their fees differ — which is exactly why APR, not the interest rate alone, is the more useful number for comparing offers.

Why a short loan term can push APR higher

APR is annualized — calculated as if the cost applied over a full year. A flat fee on a loan due in two weeks, when annualized, can produce a much higher percentage than the same dollar fee on a loan repaid over two years, even though the actual dollar cost of the short loan might be smaller. This is a common source of confusion, and it's worth understanding rather than being alarmed by the percentage alone — look at both the APR and the total dollar cost.

How to use APR when comparing offers

  • Compare the APR, not just the advertised interest rate, across every offer you're considering.
  • Multiply the APR's implied cost by the actual loan term to sanity-check the total dollar amount you'd repay.
  • Ask whether the APR is fixed for the full term or could change.
In the U.S., providers offering consumer credit are generally required under federal truth-in-lending rules to disclose the APR before you accept an offer. If a provider won't clearly state the APR, treat that as a reason for caution.
