How the APR calculator works

APR (Annual Percentage Rate) reflects the true cost of borrowing by factoring in fees on top of the stated interest rate. Fees are added to the principal and amortized over the loan term.

  • Effective principal = loan amount + fees
  • Monthly payment calculated using the standard amortization formula on the effective principal
  • APR is the stated rate that produces this monthly payment

Example: a $100,000 loan with $2,000 in fees at 6% APR over 30 years has a monthly payment of about $612, reflecting a higher effective cost than the rate alone suggests.

Use it to: compare loan offers that have different fee structures, or understand the full cost of a mortgage or other loan.
