The Gratuity Calculator is a free online tool that helps you calculate the gratuity payable on leaving a job, from your last drawn salary and years of service. Instead of working through the maths by hand, you enter a few details and get an instant, accurate result — making it easy for salaried employees in India to plan with confidence. Whether you are a first-time investor or an experienced one, the Gratuity Calculator removes the guesswork and lets you make numbers-backed decisions in seconds. This page explains what the calculator does, the formula behind it, how to use it, a worked example and the key things to keep in mind, so you can make the most of every calculation.
What is gratuity?
Gratuity is a lump-sum reward paid by an employer for long service, governed by the Payment of Gratuity Act, 1972. It becomes payable once you complete five years of continuous service, and on resignation, retirement, death or disablement. Understanding this is the first step to using the Gratuity Calculator effectively, because the quality of your result depends on the assumptions you feed in. The calculation uses your last drawn Basic + Dearness Allowance — not your full CTC — which is why the payout is usually smaller than people expect. Once you are clear on the concept, the calculator simply does the arithmetic for you — quickly, consistently and without errors.
How does the Gratuity Calculator work?
The calculator applies a standard, well-established formula so the result is consistent and reliable. In simple terms, it works out the statutory gratuity using the 15/26 formula, then caps it at the ₹20 lakh tax-free ceiling. The core formula is:
The 26 represents working days in a month and 15 represents 15 days’ wages for each completed year. Service beyond six months in the final year is rounded up to a full year. The tool does this instantly and re-calculates the moment you change any input, so you can test different scenarios in seconds — something that would take much longer, and be far more error-prone, on paper or in a spreadsheet.
Why use the Gratuity Calculator online?
Doing this calculation manually means juggling powers, percentages and long formulas where a single slip changes the answer. The Gratuity Calculator handles all of that for you and lets you compare multiple scenarios side by side, so you can see exactly how a change in one number affects the outcome. It is the fastest way to turn a rough idea about gratuity into a concrete, reliable figure you can plan around — on any device, at any time, for free.
How to use the Gratuity Calculator
- Enter your last drawn monthly salary (Basic + DA).
- Enter your total years of continuous service.
- Read the result instantly — adjust any value to compare different scenarios side by side.
Gratuity Calculator: example calculation
On a last drawn Basic + DA of ₹50,000 with 10 years of service, gratuity works out to 15 × 50,000 × 10 ÷ 26 ≈ ₹2,88,462. You can reproduce this in the calculator above and then tweak the numbers to match your own situation — that is exactly what makes an online calculator so useful for planning.
Benefits of using the Gratuity Calculator
- Know your exit payout before you resign
- Check the five-year eligibility rule
- See how the ₹20 lakh ceiling applies
- It is completely free, works on mobile and desktop, and needs no sign-up.
- It removes manual errors and saves the time of doing repeated calculations by hand.
Because you can see the outcome change in real time, the Gratuity Calculator is as much a learning tool as a planning one: it builds an intuitive feel for how each variable — amount, rate, tenure or price — affects the final number.
Things to keep in mind
Only Basic + DA counts, not your full CTC or allowances. Gratuity up to ₹20 lakh is tax-free for non-government employees; anything above that is taxable. Remember that any calculator is only as good as its inputs and the assumptions built into it. Markets, interest rates, charges and tax rules change over time, so treat the output as a well-informed estimate rather than a guarantee. For decisions involving significant money or tax, confirm the current rules and consider speaking to a qualified financial adviser.
