How Much Will My MPSERS Pension Pay Me?
Every MPSERS pension — no matter which plan you're in — comes from the same three-part formula. Once you see the shape of it, the number stops feeling like a mystery.
💬 GLP Retirement MinuteThe Formula Behind Every Pension
FAC = Final Average Compensation — not your current salary, your highest-earning consecutive years (3 or 5, depending on your plan)
The factor (1.5% for most, 1.25% for some) and the FAC averaging period (3 years for MIP, 5 for Basic) both vary — so two people with identical salaries and years of service can still land on different pensions.
This formula only calculates your smaller pension slice. You also have a separate personal savings account that this formula doesn't touch at all — your total retirement income is both pieces together, not just this number.
Try the Pension Calculator — enter your FAC and years of service and see your rough estimate in ten seconds, with the exact math shown.
Your pension is a formula, not a mystery — but it's a formula with real variables specific to you. Confirm your factor and FAC averaging period via miAccount before treating any estimate as final.
