APR vs. Interest Rate: What's the Difference?

Published 2026-09-09 Last reviewed 2026-09-09 By Lisa C Hamilton, REALTOR®

Quick Answer

The mortgage interest rate primarily reflects the cost of borrowing the principal. APR, annual percentage rate, is a broader disclosure designed to reflect certain financing costs in addition to interest. That is why APR is often higher than the note rate.

Example

Lender A: lower advertised interest rate, but high points and fees.

Lender B: slightly higher interest rate, but lower upfront costs.

APR helps provide additional context.

APR Still Doesn't Tell You Everything

APR is useful. But also compare:

  • Cash to close
  • Points
  • Lender credits
  • Monthly payment
  • Loan type
  • Mortgage insurance
  • How long you expect to keep the loan

Why Holding Period Matters

A loan with expensive upfront points may have attractive long-term economics but poor economics if you refinance quickly.

Use the points break-even calculator to compare the timing.
