Calculate Annual Percentage Rate
For a simple loan, APR is an annualized cost rate; exact APR calculations follow the applicable lending convention and fee treatment.
Formula: APR depends on periodic interest, fees and the loan balance or amount financed
Keep the interest rate, payment frequency and time period consistent. Fees, compounding rules, taxes and lender or issuer conventions can change a real-world result, so use the calculator as a calculation aid rather than a contract quote.
Recalculate the result from the displayed formula and confirm that rate, term, compounding and monetary amounts use the same time basis.
