As per the Act, the gratuity amount is 15 days’ wage multiplied by the number of years put in by you. Here wage refers to basic salary plus dearness allowance. Take the monthly salary drawn by you last (basic + dearness allowance) at the time of resignation or retirement. Divide this by 26. This gives you your daily salary. Multiply this amount by 15 days, and further by the number of years of service you have put in.
If you have put in 10 years and seven months in an organisation, your service period will be taken to be 11 years. But if your service tenure is 10 years and five months, then for the purpose of this calculation your tenure will be taken to be 10 years only.
Take an example. Suppose that your average monthly salary is Rs 26,000. Your daily salary will be Rs 1,000. Multiply this by 15 and then by 10. The gratuity you are entitled to after 10 years of service will be Rs 1.5 lakh.
Any death cum retirement gratuity received by Central and State Govt. employees, Defense employees and employees in Local authority shall be exempt.
