Whether you are resigning to join another company, retiring, or negotiating your full-and-final (FnF) exit settlement, calculating your exact statutory gratuity entitlement is essential to ensure your employer pays what you are legally owed.

The Statutory Gratuity Formula (15/26 Rule)

Under the Payment of Gratuity Act 1972, an employee's monthly salary is divided by 26 working days (excluding 4 Sundays per month) to determine their single-day wage rate, multiplied by 15 days of wages for every completed year of service:

Gratuity = (15 × Last Drawn Basic Salary + DA × Tenure in Years) ÷ 26

Rounding Rule for Tenure:

For employees covered under the Act, if your service tenure in the last year exceeds 6 months (e.g. 7 years and 7 months), it is legally rounded up to the next full year (i.e. 8 years).

The 5-Year Eligibility Rule: Can You Get Gratuity in 4.5 Years?

Section 4(1) of the Act specifies that gratuity becomes payable on the termination of employment after rendering continuous service for not less than 5 years. However, under legal precedents established by the Supreme Court and High Courts in India:

  • 6-Day Work Week: Completing 4 years and 240 days of actual working service is legally treated as 5 full continuous years.
  • 5-Day Work Week: Completing 4 years and 190 days of service satisfies the continuous service requirement.

Tax Exemption Rules under Section 10(10)

  • Government Employees: 100% tax-free with zero cap.
  • Private Sector Employees: Gratuity is tax-exempt up to a cumulative lifetime limit of ₹20,00,000 (₹20 Lakhs). Any amount paid above ₹20 Lakhs is added to taxable income and taxed at normal slab rates.
