APR Calculator

The advertised rate is never the true cost of borrowing. Enter loan amount, fees, rate and term to reveal the real APR — compare loans honestly, free.

About this tool

Two loans can advertise the same interest rate yet cost very different amounts — the difference hides in upfront fees. APR, the annual percentage rate, drags those fees into the open by folding them into one standardized yearly figure. It is the number regulators require lenders to disclose, precisely so borrowers can compare honestly.

Enter the loan amount, any upfront fees, the nominal annual rate and the term in months. The calculator shows your monthly payment, the true APR, and the total interest — so the cheapest headline rate does not fool you.

How to use

Fill in the full loan amount (before fees), the upfront fees or closing costs, the nominal annual interest rate from the offer, and the term in months. Press Calculate APR.

Compare offers by lining up their APRs side by side: the lower APR is the cheaper loan, even if its advertised rate looks higher. Try setting fees to zero to see how much of the APR was fees all along.

The math behind it

First the monthly payment comes from the standard amortization formula at the nominal rate. Then the calculator finds the single monthly rate that makes the present value of those payments equal the cash you actually receive (loan minus fees) — that rate, annualized, is the APR. With no fees it equals the nominal rate exactly.

Example: $10,000 at 12% for 12 months with $500 in fees → monthly payment $888.49, true APR about 21.86% — the fees push the real yearly cost far above the sticker rate.

Frequently asked questions

Is APR the same as the interest rate?
No. The interest rate prices the loan balance; APR folds upfront fees into the figure as well, so it reflects the true yearly cost of borrowing. The same 12% rate with $500 in fees and with zero fees produces two very different APRs — which is exactly why APR exists.
Why is the APR higher than the advertised rate?
Because fees are real costs the headline rate ignores. Spread $500 of fees over a one-year $10,000 loan and the true yearly cost jumps from 12% to about 21.86%. On long mortgages the effect is smaller, since fees amortize over many more years.
What is a good APR for a personal loan?
It depends on your credit score, the loan size and the term — excellent credit can mean single digits while weaker credit means much more. The useful move is not chasing a universal number but comparing APRs across offers: same amount, same term, lowest APR wins.
If two loans have the same APR, are they identical?
Not necessarily. APR standardizes cost but not flexibility: one loan might allow extra payments or have gentler late fees. Also check the total interest over the full term — a longer loan can share an APR yet cost far more overall.
What is the difference between APR and APY?
APR is the yearly cost of borrowing, with fees folded in and no compounding of the cost itself. APY (annual percentage yield) is the flip side for savers — what deposits grow to with compounding. Remember it as: APR for loans you take, APY for savings you keep.
