FAQ

About Business & Finance.

How accurate are the finance calculators?

Every calculator is built on standard actuarial and accounting formulas, executed with a shared Precision Engine that eliminates floating-point drift and rounds consistently to currency precision.

Which currencies are supported?

USD, EUR, GBP, INR, JPY, AUD, CAD, and AED are available in every calculator with a currency selector, using native Intl.NumberFormat for locale-correct symbols.

Do you store any of my inputs?

No. Every calculation runs entirely in your browser. Nothing is uploaded or logged, and results are never persisted server-side.

Can I export or print my results?

Yes. Every run produces Markdown, CSV, JSON, and plain-text artifacts you can copy, download, print, or share.
