Covered vs Not Covered Formulas
For organizations covered under the Payment of Gratuity Act, 1972, Gratuity equals Last Drawn Salary times 15 times Completed Service Years divided by 26 (the working days in a month). For organizations not covered under the Act, Gratuity uses the average salary of the last 10 months times 15 times completed years, divided by 30 (calendar days), and only fully completed years count.
