Step-by-step guide to calculating your WEP reduction. Learn the formula, use SSA tools, and understand how years of coverage affect your benefit.
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WEP and GPO were repealed on 5 January 2025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.”
Social Security Administration
- Signed into law
- 5 January 2025 (SSA Legislative Bulletin 118-13)
- The law
- H.R. 82, the Social Security Fairness Act of 2023 (H.R. 82 at Congress.gov)

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.
WEP reduced your Social Security by modifying the first bend point percentage from 90% down to as low as 40%. The SSA provides a free calculator at ssa.gov to estimate your exact reduction. The maximum WEP reduction in 2024 is $558 per month, and it can never exceed half your non-covered pension amount.
- The normal formula uses 90% for the first factor, and WEP cut that to as low as 40%
- Maximum WEP reduction in 2024 is $558/month and adjusts upward annually
- The half-pension rule protects workers: WEP cannot exceed 50% of your non-covered pension
- Each year of substantial SS earnings from 21-30 increases your first bend point percentage by 5%

WEP modifies the standard Social Security benefit formula by reducing the first "bend point" percentage.
- **Normal formula**: 90% of first $1,174 (2024) of AIME
- **WEP formula**: As low as 40% of first bend point
- **AIME**: Average Indexed Monthly Earnings over 35 highest years
- **Bend points**: Dollar thresholds in SS benefit calculation
- **Result**: Permanent reduction in monthly SS benefit
Using the SSA WEP Calculator
The Social Security Administration provides a free online tool to estimate your WEP-adjusted benefit.
- **Location**: ssa.gov/benefits/retirement/planner/wep.html
- **Best approach**: Create my Social Security account first
- **Information needed**: Monthly pension amount, birth date
- **Earnings history**: Pre-filled if you have SSA account
- **Years of coverage**: Count your substantial SS earnings years
How Years of Coverage Affect WEP
More years of substantial SS-covered earnings reduces your WEP penalty.
- **20 or fewer years**: Maximum WEP (40% first bend point)
- **21 years**: 45% first bend point
- **25 years**: 65% first bend point
- **29 years**: 85% first bend point
- **30+ years**: No WEP (full 90% first bend point)
Is WEP/GPO cutting into your expected retirement income?
WEP and GPO were repealed in January 2025, backdated to January 2024, so your Social Security is permanently higher than you may have planned for.
WEP Maximum Reduction Limits
WEP has caps that limit how much your benefit can be reduced.
- **2024 maximum**: $558/month reduction
- **Half-pension rule**: Cannot exceed 50% of your non-covered pension
- **Adjusts annually**: Maximum increases each year with wage growth
- **Example**: $800 pension means max $400 WEP reduction
- **Protection**: Prevents WEP from eliminating benefit entirely
Step-by-Step WEP Calculation Example
See how WEP actually affects a typical public employee's Social Security benefit.
- **Step 1**: Calculate AIME (average monthly earnings)
- **Step 2**: Apply WEP-modified first bend point (e.g., 40%)
- **Step 3**: Apply normal formula for amounts above first bend point
- **Step 4**: Compare to normal benefit to see reduction
- **Step 5**: Verify reduction doesn't exceed maximum limits

Frequently Asked Questions
1Is the WEP calculator estimate accurate?
It's an estimate based on current information. Your actual benefit depends on your final earnings record, pension amount at retirement, and Social Security formulas in effect when you claim.
2What if I don't know my exact pension amount yet?
Use an estimate from your pension administrator. You can run the WEP calculator multiple times with different pension amounts to see how it affects your Social Security.
3Should I delay Social Security with WEP?
Possibly. Delayed retirement credits still increase your WEP-adjusted benefit by 8% per year past full retirement age up to 70. Run calculations at different ages to see the impact.
4Can WEP reduce my benefit to zero?
No, WEP cannot reduce your benefit below zero. Additionally, the maximum WEP reduction is capped at both a dollar amount ($558/month in 2024) and half your non-covered pension.
