Interest-Only Payment Calculator

Calculate monthly interest-only payments on loans

About this calculator

The Interest-Only Payment Calculator helps borrowers determine their monthly payment amount when only paying interest on a loan, without reducing the principal balance. This tool is particularly useful for investors, homebuyers considering interest-only mortgages, or anyone evaluating loan options where temporary lower payments are needed. By calculating interest-only payments, you can better plan your cash flow, compare different loan structures, and understand the financial impact of deferring principal payments during the interest-only period.

How to use

Enter your loan amount, annual interest rate, and loan term into the calculator. The tool will instantly compute your monthly interest-only payment by multiplying the principal by the monthly interest rate. Compare this result with traditional amortizing loan payments to understand the difference and make informed borrowing decisions.
