Gratuity formula
Covered employers: Gratuity = Last drawn (Basic + DA) × 15 × Years of service ÷ 26
(a final period of more than 6 months counts as a full year)
Not covered: Gratuity = Average (Basic + DA) of last 10 months × 15 × Completed years ÷ 30
Tax-free amount: Government employees — all of it; others — up to ₹20 lakh in a lifetime
Worked example
Joined on 1 January 2016, left on 1 August 2026: 10 years and 7 months. The 7 months count as a year, so 11 years. Last drawn basic + DA = ₹50,000 a month. Gratuity = ₹50,000 × 15 × 11 ÷ 26 = ₹3,17,308. It is below the ₹20 lakh limit, so the whole amount is tax-free.
