What Is Service Length?

Length of service, often called qualifying service, is the foundation for nearly every retirement and career benefit a government employee receives — pension percentage, gratuity amount, MACP eligibility, and leave encashment limits all depend on an accurate service length figure.

While the basic calculation is a straightforward date difference, complications arise from breaks in service, periods of extraordinary leave, or suspension, which may or may not count towards qualifying service depending on the specific rule involved.

Knowing your exact length of service is the starting point for almost every other retirement benefit calculation. Keep this figure updated periodically, especially as you approach milestone years like 10, 20, or 33 years of service.
