Frequently asked questions

Are the formulas accurate?

Yes — calculations use the same compounding and amortization formulas banks and accountants use. Real-world contracts may include fees, rounding rules, or taxes that aren't modelled here.

Do you store my numbers?

No. The calculators run entirely in your browser; nothing is saved or sent to a server.

Which currency do these tools use?

Most calculators are currency-agnostic — they work with whatever number you enter. The labels default to a neutral '₹/USD/€' style.
