Estimate loan payment, total interest, and first-year principal/interest split.

About this amortization calculator

Estimate loan amortization for mortgages, auto loans, personal loans, and planning scenarios.

Mavis Tools is built for quick utility work: paste the input, get the result, and move on. The page is static-first for speed, and the interactive work happens in your browser. That makes it useful for drafts, calculations, debugging snippets, and repeat everyday tasks.

This tool is intentionally focused. It does one job clearly instead of asking for an account or hiding the result behind a long workflow. Bookmark it if you need a fast amortization calculator that works on desktop and mobile.
