How it is worked out
Gratuity is a lump sum an employer pays to someone who leaves after long service — on resignation, retirement, death or disablement. It applies to establishments with 10 or more employees.
The formula pays 15 days' wages for every year of service. A month's wages are treated as 26 working days, so a day's wage is the last monthly basic + DA ÷ 26.
The rules used
- Gratuity = 15 ÷ 26 × last drawn monthly basic + DA × years of service.
- A final part-year of more than six months counts as a full year; six months or less is dropped.
- Payable after at least five years of continuous service. Fixed-term employees qualify after one year under the Code on Social Security (in force since 21 November 2025). On death or disablement, there is no minimum.
- The ceiling is ₹20,00,000. Gratuity paid under the Act is tax-free up to that amount for private-sector employees.
- An employer not covered by the Act may pay gratuity voluntarily; the customary formula then is 15 ÷ 30 × salary × completed years.
Assumptions. Some courts have counted 4 years and 240 days as five years of continuous service; this calculator uses completed years. Check the treatment for your case.
