Frequently Asked
Are these calculators free to use? +
Yes. All 30 calculators are 100% free, require no signup, and run entirely in your browser. There is no paywall, upsell, or hidden fee.
Do you store or transmit my financial data? +
No. Every calculation uses client-side JavaScript. Your income, loan amounts, statutory details, and all inputs never leave your device. No cookies, no analytics events, no server logs of values.
Can I use the output for a legal filing or ITR? +
No, not directly. These are educational models. Court pleadings, ITR filings, and statutory claims must be prepared and verified by a qualified advocate or chartered accountant. Use these outputs as rough estimates only.
How often are the rates updated? +
Statutory references were verified in January 2026. However, Union Budget revisions, CBDT notifications, Supreme Court rulings, and RBI monetary policy can change rates. Always cross-check the latest official source.
Is there any warranty on accuracy? +
No. The calculators are provided "as-is" without warranty of any kind. See the full legal disclaimer below for details on limitation of liability.
