WEP Calculator Guide: How to Calculate Your Reduction
Step-by-step guide to using the Social Security WEP calculator to estimate your benefit reduction.
This rule no longer exists
WEP and GPO were repealed on 5 January 2025
If you were reading this page because you expected your Social Security to be cut by a public pension, it is not. Both rules were abolished, the change was backdated to January 2024, and the Social Security Administration has already paid the difference to everyone it identified as affected.
“December 2023 is the last month that WEP and GPO will apply. This means that those rules no longer apply to benefits payable for January 2024 and later.”

One thing that still matters
“WEP and GPO still apply to months prior to January 2024.” So the old formula is not irrelevant history: it is what determines whether the one-time payment you received was the right amount. Our back pay calculator works out what you should have been owed, so you can check it against what landed in your account.
Sources last checked 30 July 2026. The rest of this page describes how WEP and GPO worked while they were in force, and is kept because the historical formula is what the back pay was calculated from.
The SSA provides a free WEP calculator at ssa.gov that shows how much your Social Security will be reduced. You need your estimated Social Security benefit, your government pension amount, and your years of substantial Social Security-covered earnings. The maximum 2024 WEP reduction is $558 per month.
- Free WEP calculator available at ssa.gov/benefits/retirement/planner/wep.html
- WEP changes the first bend point from 90% to as low as 40% of your AIME
- The maximum reduction was half the first bend point, $558 at 2023 eligibility, and never more than half your pension
- Each year of substantial SS earnings from 21-30 increases your first bend point percentage

- WEP reduction is permanent for your retirement
- Factor reduced SS into retirement income projections
- Consider additional savings to replace lost income
- Gold IRA provides diversification beyond pension/SS

Frequently Asked Questions
1Is the WEP calculator estimate guaranteed?
No, it's an estimate. Actual benefit depends on your final earnings record, pension amount at retirement, and current Social Security formulas.
2What if my pension amount changes?
Re-run the calculator with your updated pension amount. Higher pension = higher WEP reduction (up to the maximum).
3Should I delay Social Security with WEP?
Possibly. Delayed retirement credits still increase your benefit. Run calculations at different ages to see the impact.
