About Nitro Toolz

Nitro Toolz is a library of calculators for people planning a home purchase or managing money. Each one runs in your browser, updates as you type, and shows its formulas so you can check the math.

How it works

Free calculators need no account. Pro adds premium calculators, saved calculations, CSV export and print to PDF. Nothing is calculated on a server.

Browse the mortgage, personal finance, real estate investing and productivity categories.
