Calculate Your Government Pension
Use the pensionable monthly salary and the applicable percentage from your department's pension calculation. Years of service alone do not determine the correct rate.

Government Pension Calculator for Sri Lanka
This free pension calculator helps Sri Lankan public servants and pensioners estimate their basic monthly and annual pension when their pensionable salary and applicable pension percentage are already known. It is intended as a calculation worksheet, not an official assessment of pension rights.
How to calculate a government pension in Sri Lanka
- Obtain your pensionable salary from the official pension calculation prepared by the relevant institution.
- Obtain the percentage applicable to your service, salary band, retirement date and reduced/unreduced category.
- Enter both values into the calculator and click Calculate Pension.
- Compare the estimate with your official pension documents before making financial decisions.
Why years of service alone do not determine your pension
Official percentage tables can distinguish salary ranges, completed service periods, and reduced versus unreduced pension rates. Some pensions also depend on promotion history, pensionable service adjustments and the rules applicable when the employee retires. This calculator therefore does not infer a percentage from years of service; users must provide a confirmed percentage.
2025 pension salary revisions
Department of Pensions Circular 01/2025 addresses pension calculations following public-sector salary revisions in 2025. It describes different treatment for certain retirements up to 31 March 2025 and retirements from 1 April 2025 onward. The applicable salary and gratuity rules are not necessarily identical. Always consult the circular and your institution for the correct pensionable salary and percentage.
Frequently Asked Questions
Can I calculate my pension using only my last salary?
Not reliably. You need the correct pensionable salary and the applicable rate. The last drawn amount may differ from the pensionable salary depending on the relevant rules.
Is the pension percentage the same for everyone with 30 years of service?
No. Official tables may vary by salary band, reduced versus unreduced rate, and the relevant period of service. Do not assume a universal percentage.
Does the calculator include W&OP or gratuity?
No. It estimates a basic monthly pension. Widows', Widowers' and Orphans' Pension entitlements, commutation, retirement gratuity, arrears and official revisions require separate rules.
Which retirement salary applies after 1 April 2025?
Department of Pensions Circular 01/2025 describes the use of revised full monthly salary scales for certain pension calculations after that date. Your institution must confirm the applicable provisions and salary.
Is the calculator free and private?
Yes. Calculations run on your device and this page does not submit your values to a server. You do not need to create an account.
