About the APR Calculator
The APR Calculator on truecalculator.net computes the Annual Percentage Rate for loans and credit products. You enter your loan details and receive the true yearly cost of borrowing as a single percentage. This figure includes interest plus lender fees, so you can compare offers on equal terms.
The calculator builds the periodic payment with the standard amortization formula P x r x (1+r)^n / ((1+r)^n - 1), then derives the APR by folding fees into the financed amount and solving for the rate that balances the payment stream. It needs the loan amount, nominal interest rate, term, and upfront fees such as origination charges or points. Enter every fee your lender discloses, because even small costs can shift the APR noticeably. For large borrowing decisions, consider consulting a financial professional.
- Enter the loan amount, stated interest rate, and repayment term in the input fields.
