Hi Kalpana,
Superannuation is also called Voluntary Retirement from the services. This is mainly practiced in government or semi-government bodies.
Gratuity is paid after superannuation, resignation, or retirement from the service, but only to those who have rendered continuous service for 5 years or more. Gratuity is paid at a rate of 15 days of salary for every year the individual has served the organization.
The formula to calculate Gratuity Payable is: monthly wages last drawn / 26 * 15 * Number of years.
When calculating the salary for one month, we base it on 26 working days only. For example, if someone has served an organization for 10 years and their last drawn salary was Rs. 8000 per month, the Gratuity Payable would be: 8000 * 15 / 26 * 10 (years).
The maximum amount of gratuity payable should not exceed Rs. 3,50,000 in any case. This maximum limit applies even in the case of superannuation, where the gratuity paid would remain the same.
I hope this explanation clarifies things for you.
Regards,
Amit Seth.
