Enter a loan amount, stated interest rate, fees, and term to calculate the true APR — the rate that accounts for fees, not just the nominal interest rate.
How to Use the APR Calculator
Loan amount and stated rate get you the baseline payment; add the fees and term, and the calculator works out what rate — the APR — actually produces that same payment once fees are baked in.
Two loans can quote the identical interest rate and still cost different amounts, because rate alone ignores origination fees, closing costs, and other charges rolled into the deal. APR folds those in, which is exactly why regulators in most countries require lenders to disclose it alongside the plain interest rate.
The math isn't a closed-form formula — this calculator solves for it numerically. It takes the payment your stated rate would produce, then works backward to find what interest rate, applied to the loan amount minus the fees, would generate that same payment over the same term. That rate is the APR, and it's always at least as high as the stated rate, never lower.
A $500 fee barely moves the needle on a $50,000 loan; the same $500 on a $5,000 loan can push the APR noticeably above the sticker rate. Smaller loans and shorter terms are where the gap between "rate" and "APR" tends to matter most.
