Indian gratuity payout estimate.. Gratuity Calculator is a free online tool from the ToolsRift Finance & Health Calculators collection. It runs entirely in your browser — nothing to install, no signup, and your data never leaves your device.
Enter your last drawn basic salary plus dearness allowance and your completed years of service. The calculator applies the 15/26 formula to estimate your gratuity.
For covered employees, gratuity = last drawn (basic + DA) × 15/26 × years of service. The 15/26 factor treats 15 days' wages for each completed year based on a 26-day month.
Under the Act you generally need at least 5 continuous years of service, except in cases of death or disablement where the 5-year rule is waived.
Gratuity is tax-exempt up to a statutory ceiling (₹20 lakh for most employees). Amounts above the exemption limit are added to taxable income. This is not legal advice.
