Qualifying Service Calculator for Pension and Gratuity
Pension and gratuity are worked out on qualifying service, counted in completed six-month periods rather than exact days. This counts yours from joining to retirement and applies the rounding the rules allow.
How to use this calculator
- Enter the date you joined service.
- Enter the date you retire or retired.
- Enter any non-qualifying service in months, such as extraordinary leave that does not count.
- Calculate to see your qualifying service and the six-monthly periods behind it.
How it is calculated
Your service from joining to retirement is counted with both days included — retirement takes effect in the afternoon of the last day — and non-qualifying months are taken off.
What remains is counted in six-month periods. A leftover of three months or more counts as a full period; less than three months is dropped.
The result is checked against the minimum qualifying service needed for a pension. Gratuity and pension then use the same figure.
Worked example
Joined on 1 July 1996 and retiring on 30 June 2026 with no non-qualifying service: 30 years, or 60 six-month periods, comfortably above the minimum for a pension.
