About this calculator

How-to: enter the loan principal, annual interest rate (APR) and term in months. We use the standard amortization formula M = P·r·(1+r)^n / ((1+r)^n − 1), where r is the monthly rate (APR ÷ 12) and n is the number of payments. Each month, interest = balance × r, and principal = payment − interest.

Frequently asked questions

Does this include fees or origination costs?

No — it models pure principal and interest. Add origination or arrangement fees to the loan amount to see their effect on the payment.

Is the rate APR or nominal?

Treat the input as the nominal annual rate that the lender divides by 12. If your lender quotes APR that already includes fees, the true monthly cost is slightly higher.

Can I model interest-only or balloon loans?

Not directly. This calculator is for standard fully-amortizing term loans. For interest-only, monthly payment ≈ balance × APR ÷ 12 until the balloon date.
