About Tabularo

Last updated: July 13, 2026

Free financial calculators for every money decision.

What is Tabularo?

Tabularo is a collection of 45 free financial calculators covering every major personal finance topic: mortgages, loans, debt payoff, compound interest, income taxes, retirement savings, salary conversion, inflation, and business break-even analysis. Every calculator uses verified formulas and current data — including 2026 IRS tax brackets and Social Security wage bases.

Why we built it

Most financial calculators online are cluttered with ads, demand account signups, or hide results behind paywalls. Tabularo was built to be different: instant calculations, shareable URLs, and no personal information required — ever.

We believe the math behind financial decisions should be transparent and accessible. You shouldn't need to trust a black box — you should be able to understand what the numbers mean and how they were calculated.

How we keep it accurate

All calculators use standard financial formulas verified against authoritative sources. Tax data is sourced directly from IRS publications and state tax authority websites, and is updated manually each January when new tax year data is published.

Tabularo is a tool for education and planning — not a substitute for professional financial advice. For binding financial decisions, consult a licensed financial advisor or CPA.

Privacy

All calculations happen locally in your browser. Your inputs are never sent to a server, never stored, and never shared. There are no user accounts and no personal data collected directly. We use privacy-focused analytics cookies to understand aggregate site usage, and if advertising is enabled, our advertising partner may also set cookies to serve relevant ads. See our Privacy Policy for the full list of cookies and how to opt out.

Data Sources

Federal income tax data for 2026 is sourced directly from authoritative IRS and SSA publications:

State income tax data for all 50 states is verified against each state's Department of Revenue or equivalent tax authority.

Methodology

Tax constants are updated annually, typically November–December, after the IRS and Social Security Administration publish their inflation-adjustment figures for the upcoming year. Each update follows a fetch-and-verify process:

  1. Retrieve the authoritative publications directly from IRS.gov and SSA.gov — no secondary sources, no estimates
  2. Compare each constant in the codebase against the published figures
  3. Correct any discrepancies and document the change with a source citation in the code
  4. Verify that all affected calculators produce correct outputs after the update

Financial formulas — mortgage amortization, compound interest, FICA withholding, and others — use standard mathematical definitions. They are verified once against authoritative references and remain unchanged unless the underlying formula definition changes.

Disclaimer

All content on Tabularo is provided for educational and informational purposes only. Calculator results are estimates based on the inputs you provide and the tax rates or formulas in effect at the time of the last update. They do not constitute tax, financial, legal, or investment advice.

Individual tax situations vary. For decisions with binding financial or legal consequences — including tax filing, retirement planning, and investment choices — consult a licensed CPA, financial advisor, or attorney.
