About FinCalcHub
FinCalcHub is a collection of free, no-sign-up financial calculators for the United States. Each tool answers one specific question — how much you can still contribute to a 401(k), what a Roth conversion really costs, whether mortgage points are worth it, what a nanny actually costs on the books — and every calculator is built with the current 2026 IRS and federal limits.
Why we exist
Financial decisions come down to numbers, but the numbers are often buried in IRS publications and lender rate sheets. We turn those rules into simple tools that give you an answer in seconds, for free, without creating an account or handing over your personal information.
Our accuracy promise
All tax figures (contribution limits, tax brackets, phase-out ranges, deductions) reflect the 2026 tax year and are reviewed when the IRS publishes new numbers each year. Formulas are transparent and stated on every page. Still, calculators are estimates for general information only — always confirm current rules and consult a qualified professional for decisions that matter.
How we keep it free
The site is funded by advertising. We do not sell user data, do not require accounts, and do not place content behind paywalls.
