Methodology
How this calculator works
The calculator measures calendar service from the joining date to the last working date, subtracts unpaid leave days entered by the user, and converts eligible service into years. For an eligible worker with at least one year of service, it divides monthly basic salary by 30 to estimate daily basic wage. It then applies 21 days of basic wage for each of the first five years and 30 days for each later year, including a proportional part-year after eligibility begins. A part-time work fraction can reduce the gratuity estimate, and the gratuity is capped at two years of basic wage.
