The Payment of Gratuity Act formula is (last basic + DA) × 15/26 × completed years. The 15/26 means 15 days of wages for every completed year, counted on a 26-day working month. For 31 years, the multiplier is 15/26 × 31, which is about 17.88 months of basic+DA. So an employee finishing 31 years on a basic+DA of ₹40,000 receives ₹7,15,385.
Only completed years count; a part-year over six months rounds up, under six months is dropped. Gratuity is payable on resignation, retirement, death or disablement once you cross five years of continuous service, and it is tax-free up to a lifetime limit of ₹20,00,000. Anything above that is added to taxable income.
