GSIS Pension Calculator
For government employees — estimate your monthly GSIS retirement pension from your average compensation and years of service.
Estimate your GSIS pension
| RAMC (AMC + ₱700) | |
| Basic Monthly Pension (2.5% × RAMC × years) | |
| Cap (90% of AMC) | |
| Monthly pension |
Estimate using the GSIS Basic Monthly Pension formula (RA 8291): 2.5% × RAMC × years of service, where RAMC = AMC + ₱700, capped at 90% of your AMC, with a ₱6,000 minimum. An old-age pension generally requires at least 15 years of service; with fewer, you may receive a separation/cash benefit instead. Confirm with GSIS.
How the GSIS pension is computed
Your Basic Monthly Pension (BMP) under RA 8291 is:
BMP = 2.5% × RAMC × years of service, where RAMC = AMC + ₱700
- AMC = your average monthly compensation over your last 36 months.
- Capped at 90% of your AMC.
- Minimum pension of ₱6,000 (board-approved floor, since February 2019).
