How APR Works
APR vs. Interest Rate
The interest rate determines your monthly payment. The APR reveals the full cost by folding in upfront fees. A loan with a lower stated rate but high fees can actually cost more — APR is the number to use when comparing lenders side by side.
What Fees to Include
Include every upfront lender charge: origination fees, discount points, underwriting fees, and broker fees. Do not include recurring costs like insurance or property taxes — those are not part of the APR calculation under TILA.
The TILA Standard
This calculator uses the present-value method required by the Truth in Lending Act. It finds the monthly rate where the present value of all payments equals the net loan proceeds (loan minus fees), then annualizes it. This is the same method lenders must use on your Loan Estimate.
