APR & Loan Fees Calculator

See how entered fees change a loan’s cost using a clearly defined monthly cash-flow model.

For financed fees, this is the amount you want to receive before the fee is added.
Enter the interest rate, before fees. Zero is supported.
Use a term that equals a whole number of months.
Enter charges you want included in this comparison. Legal APR rules may include or exclude different charges.

All amounts use the selected currency. Changing its label does not convert values.

Convention: equal monthly periods, first payment after one month, fixed rate, cent-rounded monthly cash flows. The headline is 12 × the monthly yield. It is not a legally disclosed APR for every jurisdiction or loan type.

What does this rate measure?

This estimates the annualized cost of the payment cash flows compared with the funds available to you after entered fees. For upfront or withheld fees, net proceeds equal the loan amount minus fees. For financed fees, the starting balance is the loan amount plus fees, while net proceeds stay equal to the original loan amount.

The model solves for a monthly yield y such that net proceeds equal the sum of each scheduled payment discounted by (1 + y) raised to its payment month. It uses the cent-rounded amortization schedule, including the adjusted final payment. The nominal annualized rate is 12 × y; the effective annual equivalent is (1 + y)12 − 1.

Why this may differ from a lender’s APR

Legal APR definitions depend on the applicable jurisdiction, loan type, which fees count as finance charges, exact dates and other assumptions. Irregular first periods, balloons, variable rates, recurring fees and prepayment charges are outside this calculator’s model. The effective annual equivalent is shown separately and is not labeled APR.

Use the same fee assumptions when comparing offers, and consult the lender’s actual disclosure before deciding. Zero fees make the nominal estimate close to the entered interest rate; cent rounding can create a small difference. A zero-interest loan can still have a positive fee-adjusted rate.

How the repayment estimate works

Payments occur at the end of equal monthly periods, with the first payment one month after the starting balance date. The interest rate stays fixed. Monthly interest equals the opening balance × annual rate ÷ 12, with the rate expressed as a decimal.

The regular payment uses the standard amortization formula. Monthly interest and payments are rounded to cents; the final payment is adjusted to clear the balance at or before the original term. Totals are the sum of the schedule, so they can differ slightly from a lender’s calculation.

Amounts are rounded to two decimal places. Terms from 1 to 600 whole months, amounts from 1 to 100,000,000 and interest rates from 0% to 100% (up to six decimal places) are supported. These are calculator limits. Very long, high-rate scenarios may be rejected when cent rounding prevents the regular payment from reducing principal.

Common questions

Can I download or print the full amortization schedule?

Yes. Download CSV includes every monthly row and the calculation assumptions. Print / Save as PDF opens your browser’s print dialog; select Save as PDF if your browser offers it.

Why is the final payment different?

Rounding regular payments and interest to cents can leave a small difference. The final payment is adjusted to repay exactly the remaining balance and that month’s interest.

Does changing currency convert the amounts?

No. It only changes the display label. Enter every amount in the same currency. The model assumes two decimal places and does not fetch exchange rates.

Method and disclosure references

The CFPB’s Appendix J describes actuarial APR calculations and annualization in U.S. consumer credit. The CFPB’s Truth-in-Lending explanation distinguishes rate and total borrowing costs. These references do not make this simplified calculator a compliant disclosure engine.
