Wisconsin WRS Calculator: How to Use It
Wisconsin WRS pays whichever is higher between the formula benefit and money purchase annuity. The Rule of 87 governs general employee early retirement, and the COLA is investment-linked rather than CPI-tied. It can go up or down.
What this calculator does
The Wisconsin WRS Calculator applies the formula benefit to your projected service and 3-year final average earnings. It uses the correct multiplier for your occupation type: 1.6% per year for general employees, 1.9% for protective occupations with Social Security, or 2.0% for protective occupations without Social Security. It checks eligibility for unreduced retirement (Rule of 87 at age 57 or older for general employees, or age 65 with any vested service), and calculates the 0.4%-per-month early reduction for members retiring before their unreduced threshold. Protective employees qualify unreduced at age 53 (without Social Security) or age 54 (with Social Security) with 25 years of service.
The money purchase comparison note is included in the results panel. The calculator shows the formula benefit: the amount WRS guarantees if the formula exceeds money purchase. If your actual money purchase annuity would be higher (typically for short-service members with significant contribution returns), WRS will pay that instead when you request your official benefit estimate.
What each input means
Occupation type
General covers most state and local government employees. Protective with Social Security covers law enforcement, fire service, and other protective-class members who participate in Social Security. Protective without Social Security covers protective-class members who opted out of Social Security (typically pre-1983 elections or certain municipal arrangements). The multiplier difference is significant on a 30-year career.
Current age and years of WRS service
Your age today and your current credited service with Wisconsin WRS. The calculator projects additional service from now to your planned retirement age. Decimals are accepted. Your annual WRS benefit statement shows your current credited service balance.
Final average earnings (3-year)
Wisconsin WRS uses the average of your three highest consecutive years of earnings. For most members this is the final three years before retirement. Enter the annual average figure. Your WRS statement includes an estimated final average earnings figure based on salary data on file.
Planned retirement age
General employees can retire with any vested service at age 55, but before 57 (or before hitting the Rule of 87 threshold) the early reduction applies. The Rule of 87 minimum age is 57. Age 65 is the standard full retirement age for any vested member. Protective employees qualify unreduced at age 53 (without Social Security) or age 54 (with Social Security) with 25 years of service.
Understanding the outputs
The Rule of 87 minimum age of 57 means a 57-year-old with 30 years (sum of 87) qualifies unreduced. But a 56-year-old with 32 years (sum of 88) does not qualify under the Rule because they haven't reached 57 yet. They'd need to retire at 56 with the early reduction or wait until 57. The minimum age is binding regardless of the sum.
The investment-linked dividend is genuinely unusual. Most state pension systems provide either a fixed COLA or a CPI-capped COLA. Wisconsin WRS adjusts benefits based on core fund investment performance. Strong years produce increases above what a CPI system would provide. Poor years produce benefit decreases. In 2009, WRS actually cut retiree benefits by about 2% due to investment losses. This volatility is real and worth planning around.
The protective occupation multipliers produce substantially higher benefits. A protective employee without Social Security with 30 years on a $70,000 FAE earns $42,000/year (2.0% times 30 times $70,000). A general employee with identical inputs earns $33,600/year (1.6% times 30 times $70,000). That's an $8,400/year gap, growing with any dividend adjustments.
Formula vs money purchase: when does money purchase win?
Money purchase wins most often for members who leave WRS early and let their account balances grow through investment returns before claiming. If you contributed 6.8% of salary for 10 years, left WRS, and the account compounded for another 15 years, the annuity value of that account might exceed the formula benefit from 10 years at 1.6%. For members who stay for a full career, the formula almost always wins.

Frequently asked questions
How does the formula vs money purchase comparison work?
WRS calculates both and pays whichever is higher. Formula: multiplier times service times 3-year FAE. Money purchase: contributions plus investment returns converted to an annuity. For full-career members the formula almost always wins.
How does the Rule of 87 work?
Age plus WRS service must equal 87 or more, with a minimum age of 57. A member at 60 with 27 years qualifies unreduced. You also qualify at age 65 with any vested service.
How does the COLA work?
Investment-linked annual dividend, not a fixed CPI percentage. Can go up in strong markets or down in poor ones. In 2009, benefits actually decreased. The calculator shows 0% as a baseline since the dividend cannot be predicted.
What is the early retirement reduction?
0.4% per month before the earliest unreduced age. Retiring at 55 when the Rule of 87 does not yet apply means 120 months before 65, or a 48% reduction. Retiring at 60 when Rule of 87 is not yet met means 60 months before 65, or a 24% reduction.
How is the 3-year FAE calculated?
Average of your three highest consecutive years of earnings. Typically the final three years for members with steady salary growth. Your annual WRS statement shows the estimated FAE on record.
