Compute payable gratuity under the Payment of Gratuity Act, 1972 (15/26 formula)
Include Dearness Allowance (DA) if anyHow Gratuity Works — and How to Calculate Exactly What You're Owed
Most employees know gratuity exists somewhere in their offer letter, buried under CTC breakdowns, but few actually understand how the number gets computed. That gap costs people money. This guide walks through the real mechanics — the formula, the rounding rules, the ₹20 lakh ceiling, and the specific differences between retiring and resigning — so you know your entitlement before your last working day.
The Legal Foundation: Payment of Gratuity Act, 1972
Gratuity in India is governed by the Payment of Gratuity Act, 1972, which applies to any establishment employing 10 or more people (once the threshold is crossed, it stays covered even if headcount later dips). The Act mandates a lump-sum payment to an employee as a reward for long service. It is not a bonus, not a provident fund contribution — it is a statutory right earned over time, payable on separation.
The formula is deceptively simple: (Last drawn Basic Salary + Dearness Allowance) × 15 × Completed Years of Service ÷ 26. The number 26 represents the working days in a month (excluding four Sundays), and 15 represents the 15 days' wages per year of service that the law mandates. Every variable in this formula carries specific legal meaning, which is where most confusion arises.
What Counts as "Basic + DA"?
Only basic salary and dearness allowance feed into the gratuity formula. HRA, special allowances, conveyance, medical reimbursement, performance bonuses — none of these count. This is why companies with inflated special allowance structures tend to result in lower gratuity payouts than their headline CTCs suggest.
For employees in the private sector where DA is zero (common in IT and startup jobs), only the basic salary is used. If your CTC shows ₹12 lakhs per year with a basic of ₹3.5 lakhs annually, your monthly basic for the gratuity formula is ₹29,167 — not the gross figure, not the CTC divided by 12.
The 5-Year Eligibility Rule — and Its Critical Exceptions
Here is where many employees and even some HR departments get confused. The general rule is that you must have completed at least five years of continuous service to be eligible for gratuity under resignation or retirement. Clock in at 4 years and 11 months and quit voluntarily? Statutorily, nothing is owed.
But there are two major exceptions that flip this rule entirely:
Death or permanent disability: If an employee dies or suffers a permanent disability during service, gratuity becomes payable regardless of how long they served. One year of service, two months — it doesn't matter. The amount is calculated on actual service rendered, with the same 15/26 formula.
Retrenchment: When an employer terminates employment due to business reasons (layoffs, closure, redundancy), the 5-year minimum does not apply. The Act protects employees from bearing the cost of the employer's business decisions.
The 6-Month Rounding Rule — Read This Carefully
The Supreme Court of India, in various judgments interpreting the Act, established that when calculating completed years of service, if an employee has worked more than 6 months beyond the last full year, the service is rounded up to the next complete year.
Concretely: if you have served 7 years and 8 months, the effective years used in the formula become 8 years, not 7. If you have served 7 years and 4 months, only 7 years count. This rounding can make a material difference — on a ₹50,000/month basic, one extra year rounds to ₹28,846 additional gratuity.
This rounding applies for regular retirement and resignation. For death and disability cases, actual service in fractional form is used by some courts, though the 6-month rounding is still widely applied in practice.
The ₹20 Lakh Ceiling
As of the 2010 amendment to the Payment of Gratuity Act (subsequently raised from ₹3.5 lakh → ₹10 lakh → ₹20 lakh), the maximum gratuity payable under the Act is capped at ₹20,00,000. Any amount computed by the 15/26 formula above this ceiling is not mandatorily payable — though employers can voluntarily pay more (and many large corporates do, calling it "ex-gratia" for the excess portion).
At what salary level does the cap kick in? Working backwards: ₹20,00,000 = (Basic + DA) × 15 × Years ÷ 26. For someone with 30 years of service, the formula equals (Basic) × 450 ÷ 26 = (Basic) × 17.31. That means basic above ₹1,15,540/month will hit the cap at 30 years of service. Senior executives routinely hit this ceiling long before retirement.
Tax Treatment of Gratuity
The tax rules differ by employer type. For government employees (central, state, defence), the entire gratuity received is exempt from income tax, with no upper limit. For private-sector employees covered under the Payment of Gratuity Act, the exemption is the least of three amounts: (a) actual gratuity received, (b) ₹20 lakh, or (c) the amount computed by the 15/26 formula. In practice, for most employees, the formula amount equals the actual amount, so the effective exemption is simply the lower of received amount and ₹20 lakh.
For private employees NOT covered by the Act (some smaller establishments), the formula changes to 15/30 instead of 15/26, and the tax calculation method differs slightly. Always confirm which formula your employer applies.
Worked Examples to Lock in the Math
Example 1 — Mid-career resignation: Rahul leaves after 9 years and 7 months. Basic + DA = ₹42,000/month. Since he has 7 months beyond his last full year (≥ 6), effective years = 10. Gratuity = ₹42,000 × 15 × 10 ÷ 26 = ₹2,42,307.69 ≈ ₹2,42,308. Well under the cap. Fully tax-exempt.
Example 2 — Long-serving senior employee hitting the cap: Meera retires after 32 years and 3 months. Basic + DA = ₹1,20,000/month. Effective years = 32 (only 3 months, less than 6, so no rounding). Raw gratuity = ₹1,20,000 × 15 × 32 ÷ 26 = ₹22,15,384. This exceeds ₹20 lakh, so payable gratuity = ₹20,00,000. The ₹2,15,384 excess is the employer's discretion.
Example 3 — Death before 5 years: An employee passes away after 3 years and 2 months. Basic = ₹28,000. Effective years = 3 (2 months < 6). Gratuity payable to nominee = ₹28,000 × 15 × 3 ÷ 26 = ₹48,461. No 5-year eligibility applies.
When Must the Employer Pay?
The employer must pay gratuity within 30 days of it becoming due. If payment is delayed without justification, the employer must pay simple interest at the rate prescribed by the government (currently 10% per annum) from the due date. You can file a claim with the Controlling Authority (typically the Labour Commissioner) if payment is refused or delayed. The limitation period for filing a claim is typically one year from the date it became due, though this can be condoned for sufficient cause.
Understanding these details changes your negotiating position. Whether you are approaching retirement, planning a job switch after many years at the same company, or processing payroll for employees — the formula is the same. The variables that shift are eligibility, rounding, and whether the ceiling applies. Get those right, and the number computes cleanly every time.
