How the 15/26 Gratuity Formula Works
The statutory formula pays 15 days of wages for each completed year of service, and it values a month at 26 working days rather than calendar 30 or 31. That is where the familiar 15/26 multiplier comes from — it equals half a month of wages per year of service. On a last drawn basic plus DA of ₹50,000, one year of service is worth ₹28,846.15, so each additional year of tenure adds exactly that amount to the payout.
Run the default case: ₹50,000 basic plus DA with 20 years and 6 months of service. The six months rounds up to a 21st year, so the payout is ₹50,000 × 15/26 × 21 = ₹6,05,769.23. Notice how much the rounding matters — without those extra six months the figure would be ₹5,76,923.08, a difference of ₹28,846.15 for waiting exactly half a year longer before resigning.
The wage base is deliberately narrow: only basic pay plus dearness allowance from your final payslip counts. Performance incentives, bonuses, house rent allowance, and conveyance are all excluded. The Act also uses the last drawn salary, not a career average, so a final-year promotion or a pay cut during the notice period directly moves the gratuity amount. Pull your latest payslip before entering a number here.
The Six-Month Rounding Rule
The rounding rule under the Act counts service beyond six months as a full additional year and drops anything shorter. Seven years and four months is therefore treated as seven years, while seven years and seven months becomes eight. On a ₹50,000 basic the first case pays ₹2,01,923.08 and the second ₹2,30,769.23 — a ₹28,846.15 swing from three extra months of service.
This cliff structure makes resignation timing financially meaningful. Crossing the six-month mark of a partial year adds a full 15-day tranche to the payout, while leaving just before it adds nothing. Someone planning to quit at the 20-year mark should check whether reaching 20 years 6 months first is worth roughly ₹28,846 per ₹50,000 of basic — usually a matter of one extra payslip cycle.
Employees of establishments not covered by the Act lose both the rounding and the 15/26 basis. Their formula is half a month of average basic plus DA per completed year, so 20 years at ₹50,000 pays ₹5,00,000 rather than ₹6,05,769.23 under the covered route — a gap of ₹1,05,769.23. Confirming coverage status with HR before modelling numbers is the single most consequential input in this calculation.
Eligibility: Five Years, 240 Days, and the Death Waiver
Continuous service of five years is the basic eligibility test, and it is measured in qualifying service rather than calendar presence — 240 working days in a year counts as a full year under Section 2A. That matters because the five-year minimum can be met with four years plus 240 working days in the fifth year, a reading the Madras High Court endorsed in the Mettur Beardsell case and which most large employers now follow in practice.
In practice, 240 working days lands at roughly four years and eight months, which is why this calculator treats covered employees with 4 years 8 months or more as eligible. At a ₹50,000 basic the payout at exactly five counted years is ₹1,44,230.77. Employees who left after 4 years and 6 months, though, generally fall short of both tests and receive nothing without a death or disablement trigger.
Death and permanent disablement waive the five-year minimum entirely — even two years of service generates a payout. A covered employee with 3 years and 9 months of service counts as four years, producing ₹1,15,384.62 on a ₹50,000 basic. This is also why keeping the Form F nomination current matters: on death the amount goes to the nominee, and an outdated nomination can force the family through succession paperwork at the worst possible time.
Covered vs Non-Covered Establishments
The Act covers factories, mines, oilfields, plantations, ports, railways, and shops or establishments with ten or more employees — and once covered, an establishment stays covered even if headcount later falls below ten. For private companies this makes coverage the norm rather than the exception, but startups and very small offices can still sit outside it. Your status decides which formula applies to your settlement.
Covered employees get 15/26 with six-month rounding; non-covered employees get half a month per completed year with no rounding, using the average basic plus DA of the last ten months. The tax cap of ₹20,00,000, once an advantage of the covered route, was extended to non-covered employees from January 2024, so the two tracks now differ mainly in the payout formula itself.
Seasonal establishments follow a different scale: seven days of wages per season instead of fifteen days per year. Plantation and construction workers on season-based contracts should ask HR which convention their settlement letter uses before treating any online estimate, including this one, as final. The year-round 15/26 math does not map cleanly onto season counting, and the gap can be substantial.
Tax Exemption Under Section 10(10)
For employees covered by the Act, Section 10(10) of the Income-tax Act exempts the least of three numbers: the gratuity actually received, the 15/26 formula amount, and ₹20,00,000. Government employees are fully exempt with no cap arithmetic involved. Most private-sector resignations land at or below the formula amount, which means the entire payout walks out tax-free.
Exemption bites when an employer pays above the statutory formula, which generous company schemes often do. Suppose a plan pays one month of basic per year of service — ₹10,00,000 after 20 years at ₹50,000 — while the statutory formula yields ₹5,76,923.08. Only ₹5,76,923.08 is exempt; the remaining ₹4,23,076.92 is taxed at your slab rate, costing about ₹1,32,000 for someone in the 30% bracket plus 4% cess.
That is the reason this calculator accepts the amount actually received as an optional field. Leave it at zero and the tool assumes payment at the statutory estimate and reports the exemption on that basis. Enter your real settlement figure instead, and the output splits it into exempt and taxable portions instantly — the number your chartered accountant needs before filing the return.
The ₹20 Lakh Ceiling and High Earners
The statutory ceiling was doubled from ₹10,00,000 to ₹20,00,000 in March 2018, and it has not moved since. Long-service high earners now hit it regularly: a ₹2,00,000 basic over 30 years computes to ₹34,61,538.46, but the payable gratuity stops at ₹20,00,000 — leaving ₹14,61,538.46 of computed entitlement outside the statutory promise. Employers can still choose to pay it, yet the excess is taxable.
The cliff location scales with basic. At ₹1,00,000 basic, 30 years pays ₹17,30,769.23 and stays under the cap; at ₹1,50,000 the same career computes to ₹25,96,153.85, so the payout is trimmed to ₹20,00,000 and ₹5,96,153.85 of computed value evaporates. Executives negotiating exit packages should treat anything above the ceiling as regular bonus income when comparing offers.
Many CTC letters show a gratuity provision of about 4.81% of basic — that is the annual accounting accrual companies book (15/26 divided by 12). Reading your annual salary calculator breakdown alongside this number clarifies how much of the package is deferred until exit. And since the cap has been frozen since 2018 while salaries compound, the inflation calculator is a fair reminder that the ceiling erodes in real terms every year it goes untouched.
Getting Paid: Claims, Nomination, and Delay Interest
Payment follows a set sequence: the employee or nominee applies in Form I, the employer determines the amount within about 15 days, and payment is due within 30 days of the gratuity becoming payable. The Act authorises simple interest on the unpaid balance for delay at a notified rate. In practice most settlements are processed with the full-and-final statement, which is exactly where discrepancies tend to surface.
If the employer disputes eligibility or amount, the controlling authority appointed under the Act hears the matter, and employees can escalate beyond that. Common friction points include the employer using gross instead of basic plus DA, ignoring the six-month rounding, or counting service from a probation start date that differs from payroll records. Keeping appointment letters, increment letters, and payslips makes these arguments short.
Forfeiture is narrow by design. Gratuity can be withheld or reduced only when termination is for riotous or disorderly conduct, or for an act constituting an offence involving moral turpitude committed in the course of employment — and even then, only to the extent the employer specifies. Poor performance, cost-cutting layoffs, and ordinary disciplinary exits do not touch the entitlement.
Gratuity vs Your Other Exit Money
Gratuity is usually the smallest of the exit payments. The same ₹50,000 basic earning 8.25% for 20 years in EPF compounds into a corpus several times larger — run the EPF calculator side by side with this tool to see the gap. Gratuity grows linearly (₹28,846.15 per year at that basic) while EPF compounds on both contributions and interest, which is why the curves diverge with tenure.
Leave encashment is the third leg of an exit settlement and has its own exemption lane under Section 10(10AA), capped at ₹25,00,000 for non-government employees since April 2023. It is computed on your last drawn salary, so a final-year raise lifts both the encashment and the gratuity base together. None of these amounts stack into one exemption pool — each is tested separately at filing time.
Between jobs, gratuity often functions as the bridge: it arrives as a lump within weeks of the last working day, before the next salary cycle starts. Planners commonly suggest parking it in a liquid instrument first rather than rushing an investment decision — a disciplined emergency fund calculator check shows whether part of it should simply stay as six months of runway instead of being deployed into something illiquid.
Putting the Payout to Work
Once the cash position is settled, the classic placements are fixed income and equity. A five-year fixed deposit of the default ₹6,05,769.23 at 7% compounds to ₹8,49,622.68 — see the fixed deposit calculator for your own bank's rate. If the money is earmarked for a house down payment or education, size the split with a savings goal calculator before committing tenures.
Equity-linked savings schemes remain the tax-saving route many redirect gratuity into, with a three-year lock-in and Section 80C deduction headroom — model the corpus effect in the ELSS calculator. The compounding difference over 10 to 15 years dwarfs the rate differences between instruments, and the compound interest calculator makes that gap visible in a single run.
For those exiting at 58 or 60, gratuity is retirement capital arriving at the doorstep. Pair a retirement countdown calculator timeline with an annuity payout calculator run to see what monthly income the lump sum could buy immediately. Employees exiting earlier should resist annuitising — the years of compounding they give up are worth more than the guarantee they buy.
