Calculator FAQs

Are these calculators free to use?+

Yes — every calculator on this page is completely free, requires no sign-up, and runs entirely in your browser. We don't store the numbers you enter.

How accurate are the results?+

The calculators use standard formulas (e.g. the reducing-balance EMI formula, the Payment of Gratuity Act formula, and statutory HRA rules). Results are indicative estimates for planning; for filing and compliance, confirm with a Tax-Eazy expert.

Which HRA exemption rule is used?+

HRA exemption (available under the old tax regime) is the least of: actual HRA received, rent paid minus 10% of basic salary, and 50% of basic for metro cities / 40% for non-metro cities.

How is gratuity calculated?+

For employees covered by the Payment of Gratuity Act: Gratuity = (Last drawn Basic + DA) × 15 × years of service ÷ 26. Gratuity received is tax-exempt up to ₹20 lakh.
