Common questions
Are these calculators free?
Yes. Every calculator and guide is free to use, with no sign-up and no limit on how many times you use them.
Do the calculators use 2026 numbers?
Yes. Tax brackets, the standard deduction, 401(k) and IRA limits, FICA rates and RMD rules are set to the figures the IRS and SSA published for 2026. Each page shows when it was last reviewed.
Do you store what I enter?
No. The math runs in your browser, and the numbers you type are not sent to or saved on our server. See our Privacy Policy for details.
Can I rely on the results for a big decision?
Use them to understand your options and check the math. Results are estimates, not financial, tax or legal advice, so confirm important numbers with your employer, lender or a qualified professional. Read our Disclaimer.
I found a mistake. How do I report it?
Email us from the Contact page with the calculator name and the numbers you entered, and we will check it.
