Formula
Payment is calculated on loan amount plus financed fees at the stated rate. Estimated APR solves the monthly rate where the present value of payments equals loan amount minus cash fees, then multiplies by 12.
APR Calculator
APR Calculator estimates a broad annual percentage rate from note rate, fees, cash charges, term and payment timing.
Worked example
A 25,000 loan with 600 financed fees and 250 cash fees at a 7.25% note rate over 60 months gives a higher fee-adjusted APR than the stated rate because the borrower receives less net value than the repayment stream implies.
Professional note
APR is most useful when two offers have similar monthly payments but different fees. Compare the fee-adjusted rate and total finance charge side by side.
Regional and unit assumptions
The calculator is currency-neutral and uses a monthly amortisation schedule. Enter the interest rate as an annual percentage, such as 6.5 for 6.5%.
Assumptions and limitations
- Monthly payments are level across the term.
- Financed fees are added to the balance and cash fees reduce net proceeds.
- The APR is an educational estimate and may not match jurisdiction-specific disclosure rules.
- Taxes, insurance, penalties and irregular payment dates are not included.

Questions
How is a loan payment calculated?
For a fixed-rate amortising loan, the calculator converts the annual interest rate to a monthly rate, counts the number of monthly payments, then applies the standard payment formula.
Does this include taxes or insurance?
No. The result estimates principal and interest only. Property taxes, insurance, fees and other charges need to be added separately.
What happens if the interest rate is zero?
When the interest rate is zero, the calculator divides the principal by the number of monthly payments.
Can extra monthly payments reduce interest?
Yes, if the lender applies the extra amount to principal and does not charge a penalty. The calculator shows a payoff estimate for that simple case.
Calculation note
APR exists because a loan rate alone can hide fees. A broader percentage helps compare offers that package costs differently.
Fees change the real borrowing cost
If a borrower receives less cash than the repayment stream suggests, the effective annual rate is higher than the headline note rate.
Disclosure rules vary
This calculator shows the arithmetic idea behind APR, but official APR calculations can depend on local law, timing and fee-inclusion rules.
