Simple tools, honest math

Quick calculators for common money questions. They run in your browser, store nothing, and show their assumptions. 2026 limits come straight from the IRS, with sources on each page.

Educational only, not financial advice

This tool shows general math, not a recommendation for you. It isn’t financial, tax or legal advice, and real returns, fees and tax rules will differ. Talk to a qualified professional before making decisions. What you enter stays in your browser: nothing is saved or sent to us.
