Our Principles

Accuracy First

Every calculator uses real data from official sources — the IRS, HUD, Tax Foundation, U.S. Census Bureau, and Federal Reserve. We cite our sources and show when data was last updated so you can assess its freshness.

Full Transparency

Each calculator page includes a detailed methodology section explaining exactly how results are computed. We show our formulas, explain our assumptions, and note any simplifications. No black boxes.

Privacy Respected

All calculations run entirely in your browser. We never transmit your financial data to any server. No registration required. No email harvesting.

Always Free

Every calculator on StateCalc is free to use, with no premium tiers or paywalls. The site is supported by non-intrusive advertising.

Data Freshness

We update our data regularly to reflect current tax rates, FMR values, property tax rates, and other financial data. Each calculator page shows when its underlying data was last updated. If you notice outdated data, please let us know.
