How it works
r = i / 12 / 100; P = S × r / (1 − (1 + r)⁻ⁿ)
Using the calculator
Enter: Loan amount · Annual rate · Term in months. Calculation: r = i / 12 / 100; P = S × r / (1 − (1 + r)⁻ⁿ).
Worked input and result
Example: Loan amount = 120,000; Annual rate = 12 %; Term in months = 24. Result: Monthly payment = 5,648.82 (Total payments: 135,571.6; Interest: 15,571.6).
Understanding the result
Equal monthly payments at a fixed rate. The monthly rate is the annual rate divided by 12 and 100. At 0% the payment is the amount divided by the number of months. Fees and insurance are excluded; the lender’s schedule may differ. Use any single currency.
The payment estimate assumes equal monthly payments and a fixed annual nominal rate. Origination fees, insurance, variable rates and lender-specific rounding are not included.
