Your estimated Iowa IPERS pension
Updates as you type.
Educational estimate only, not financial advice. Uses a simplified Iowa IPERS formula and your inputs; your real benefit varies by tier, service, age, and salary rules.
How the Iowa IPERS formula works
IPERS uses a 2% multiplier per year for your first 30 years (a 60% maximum on the base formula), plus an additional 1% per year for years 31 to 35, applied to your highest five-year average salary. Your benefit is also adjusted by a membership factor if you retire before your normal retirement age.
This calculator uses a single percentage and a simplified formula, so treat the result as an estimate and confirm your figure with IPERS. Iowa teachers also pay into Social Security.

Questions
How is a Iowa IPERS pension calculated?
The IPERS benefit multiplies a 2.0% multiplier by your highest average salary by your years of service. For example, 30 years at a $55,000 highest average salary is 2.0% × $55,000 × 30 = $33,000 per year before any early-retirement reduction.
What multiplier does Iowa IPERS use?
It is 2.0% per year of service. Adjust the percentage on the calculator if your tier or service level uses a different rate.
Do Iowa teachers get Social Security?
Yes. Iowa teachers pay into Social Security, so most receive a IPERS benefit plus a Social Security benefit. Adding any 403(b) or 457(b) savings completes the picture.
