Quick answer

Interest rate is the cost of borrowing the money. APR is interest plus most required fees, expressed as a yearly percentage — the closer-to-honest cost of the loan.

Side by side

Interest rate

  • Just the cost of the borrowed money.
  • Used to calculate your monthly payment.
  • Lower-looking — no fees baked in.

APR

  • Interest + most required lender fees.
  • Standardized for comparison across lenders.
  • Almost always higher than the interest rate.
