Gratuity is a lump-sum reward your employer pays for long service — a genuine thank-you that can run to several lakh rupees when you leave after many years. Yet most employees have only a vague idea of how it is worked out or when they become entitled to it. Understanding the formula helps you plan your finances around a job change or retirement and check that the amount you receive is correct. This guide covers eligibility, the calculation, the tax treatment and a worked example.
Who is eligible
Gratuity is governed by the Payment of Gratuity Act, which applies to establishments with 10 or more employees. The core rule is five years of continuous service with the same employer — reach that milestone and you qualify when you leave, whether you resign, retire or are laid off. There is one humane exception: the five-year condition is waived if service ends due to death or disablement, in which case the nominee or employee receives gratuity regardless of tenure. Note that gratuity is paid on exit, not annually — it accrues silently and is handed over when you leave.
The formula
For employees covered by the Act, gratuity is calculated as:
Gratuity = Last drawn salary × 15 ÷ 26 × years of service
Two parts need explaining. "Last drawn salary" means your last basic salary plus dearness allowance — not your gross pay or CTC. The fraction 15 ÷ 26 represents 15 days of salary for each completed year, where 26 is taken as the number of working days in a month (excluding Sundays). So in effect you earn roughly half a month's basic salary for every year served.
A worked example
Suppose your last basic + DA is ₹50,000 a month and you have completed 10 years of service. Your gratuity is 50,000 × 15 ÷ 26 × 10 = ₹2,88,462. If you had served 20 years, it would double to about ₹5.77 lakh. The Gratuity Calculator works this out instantly from your salary and tenure, so you can see your entitlement before a resignation or plan it into your retirement corpus.
How years of service are rounded
A detail that changes the payout: for the years-of-service figure, a part-year of more than six months is rounded up to a full year, while six months or less is rounded down. So 10 years and 7 months counts as 11 years, but 10 years and 4 months counts as 10. If you are close to a threshold, staying a few extra months to cross the six-month mark can add a meaningful amount — worth knowing when you plan the timing of a resignation.
The tax exemption
Gratuity enjoys a generous tax break, but the rules differ by employer type. For government employees, gratuity is fully tax-free. For private-sector employees covered by the Act, the exemption is the lowest of three figures: the actual gratuity received, ₹20 lakh (the current lifetime ceiling), or the amount given by the formula above. Anything beyond the exempt figure is added to your taxable income. Because the ₹20 lakh ceiling is a lifetime limit across all employers, large payouts from a long career can eventually become partly taxable — factor this into your planning with the Income Tax Calculator.
Employees not covered by the Act
Some employees work for establishments outside the Act's scope. They may still receive gratuity under company policy, but the calculation differs slightly — typically based on half a month's average salary for each completed year, using the actual days in a month rather than the 15/26 convention. If your employer is not covered by the Act, check your employment terms for the exact basis, as the figure can differ from the standard formula.
When and how it is paid
Once you become eligible and leave, the employer must pay gratuity within 30 days; delays beyond that attract interest. It is wise to file the gratuity claim (Form I) promptly and to have nominated a beneficiary (Form F) at the start of employment, so the amount reaches the right person without dispute if the worst happens. If an employer wrongly withholds gratuity, you can approach the controlling authority under the Act, which has the power to order payment along with interest for the delay. Keeping your nomination up to date whenever your family circumstances change — a marriage, a birth — ensures the payout is never held up by a dispute over who is entitled to receive it.
Can an employer refuse to pay gratuity?
Gratuity is a legal right, not a discretionary bonus, so an employer covered by the Act cannot simply withhold it from an eligible employee. There is a narrow exception: gratuity can be forfeited, wholly or partly, if your services were terminated for wilful misconduct, riotous behaviour, or an act of violence, or for an offence involving moral turpitude committed in the course of employment — and even then, only to the extent of any loss caused. A resignation, redundancy or normal retirement never justifies forfeiture. If an eligible employer delays payment beyond the statutory 30 days, they owe simple interest on the amount, and you can escalate to the controlling authority under the Act. Keep your appointment letter, salary slips and service record; they are the proof that establishes both your eligibility and the salary figure the calculation rests on.
Fitting gratuity into the bigger picture
Gratuity is one piece of your exit benefits, alongside your provident fund, leave encashment and any pension. Treated well, a gratuity lump sum is an excellent seed for long-term investment rather than a windfall to spend — reinvested, it compounds for years.

Key takeaways
- You generally need 5 years of continuous service to qualify (waived on death or disablement).
- Formula: last basic + DA × 15 ÷ 26 × years of service.
- Service over 6 months in the final year rounds up to a full year.
- Up to ₹20 lakh is tax-exempt for covered private employees (a lifetime limit); government gratuity is fully exempt.
