APR vs interest rate

The interest rate is the cost of borrowing the loan principal, expressed as a yearly percentage. The APR, or annual percentage rate, rolls most of the loan fees into that figure, so it is usually higher and is the better number for comparing the true cost of two loans.

What each number includes

The interest rate, sometimes called the note rate, is what sets your monthly payment. It is charged only on the principal. The APR takes that rate and adds most of the upfront costs of getting the loan, such as origination fees, points, and certain closing costs, then expresses the whole thing as a single yearly rate. Because it includes fees, the APR is almost always higher than the interest rate, and the gap tells you how expensive the fees are.

A worked example

Two loans can share the same rate but have very different APRs if one charges heavy fees.

Worked example: $250,000 loan, 30 years
  • Note interest rate6.5 percent
  • Monthly payment (rate only)$1,580
  • Upfront fees$6,000
  • APR including those fees≈ 6.74 percent

The payment is set by the 6.5 percent rate, but the loan really costs about 6.74 percent a year once the fees are counted. A competing loan advertised at 6.4 percent with 12,000 dollars in fees could easily have a higher APR, and cost you more.

Which number to use, and its limits

Compare loans of the same type and term by APR, because it captures fees the sticker rate hides. But APR has a blind spot: it spreads the fees over the full loan term. If you sell or refinance early, you never reach the point where a low rate with high fees pays off, so a loan with lower fees and a slightly higher rate can be the better deal. Compare APR first, then sanity check it against how long you actually expect to keep the loan.

Frequently asked questions

Why is APR higher than the interest rate?
Because APR includes most loan fees, such as origination charges, points, and some closing costs, on top of the interest itself. The interest rate covers only the cost of borrowing the principal, so the fee inclusive APR is normally higher.
Which should I use to compare loans?
APR, for loans of the same type and term, because it reflects fees that the headline rate ignores. Just remember APR assumes you keep the loan for its full term, so factor in how long you actually plan to hold it.
Does a lower APR always mean a cheaper loan?
Usually, but not if you leave the loan early. APR spreads fees across the whole term, so a low rate with high upfront fees only pays off if you keep it long enough. For short holding periods, lower fees can beat a lower APR.
Is APR the same on credit cards?
The idea is similar but the mechanics differ. Credit card APR is the yearly interest rate on carried balances, and cards usually do not fold fees into it the way loans do. On a card, the APR and the interest rate are effectively the same number.
