If you're receiving Social Security Disability Insurance — or expecting to start — the 2023 Cost-of-Living Adjustment (COLA) was one of the most significant benefit increases in decades. Understanding how it works, what it changed, and why individual results still vary is essential for anyone trying to plan around their SSDI income.
Each year, the Social Security Administration adjusts benefit amounts based on inflation data from the Consumer Price Index for Urban Wage Earners and Clerical Workers (CPI-W). This adjustment is called the Cost-of-Living Adjustment, or COLA.
The COLA is applied automatically — you don't need to apply, request it, or contact the SSA. If you're already receiving SSDI, the increase is built into your January payment.
For 2023, the SSA announced a 8.7% COLA — the largest increase since 1981. That figure reflected the significant inflation Americans experienced throughout 2022.
The COLA percentage is applied to your existing benefit amount, not to some fixed national average. That means the dollar increase you saw depended entirely on what you were already receiving.
Here's how the math worked across a range of benefit levels:
| Monthly Benefit Before 2023 | 8.7% Increase | New Monthly Benefit |
|---|---|---|
| $800 | +$69.60 | ~$870 |
| $1,200 | +$104.40 | ~$1,304 |
| $1,500 | +$130.50 | ~$1,631 |
| $1,800 | +$156.60 | ~$1,957 |
| $2,200 | +$191.40 | ~$2,391 |
The average SSDI benefit entering 2023 was approximately $1,483 per month before the adjustment — meaning the average recipient saw a monthly increase of roughly $129. But "average" is a blunt instrument here. Your actual benefit could be well above or below that depending on your earnings history.
To understand why the 2023 COLA affected people differently, it helps to understand how SSDI benefits are calculated.
Your monthly SSDI payment is based on your Primary Insurance Amount (PIA) — a figure the SSA calculates using your lifetime earnings record. Specifically, it uses your Average Indexed Monthly Earnings (AIME), which adjusts your historical wages for wage growth and averages them across your highest-earning years.
The SSA then applies a progressive benefit formula to your AIME. This formula replaces a higher percentage of earnings for lower earners than for higher earners — which is why two people with different work histories receive very different monthly amounts.
Key factors shaping your base benefit:
Because the 8.7% COLA is applied to whatever your PIA-based benefit already is, people with higher base amounts saw larger dollar increases — even though the percentage was identical for everyone.
The COLA wasn't the only number that changed on January 1, 2023. Several program thresholds also adjusted:
Substantial Gainful Activity (SGA): The monthly earnings limit for non-blind SSDI recipients rose to $1,470 (up from $1,350 in 2022). For blind recipients, the SGA threshold increased to $2,460. Earning above SGA can affect your eligibility to continue receiving benefits.
Trial Work Period (TWP) threshold: The monthly earnings amount that triggers a trial work period month increased to $1,050.
Maximum taxable earnings: The Social Security wage base rose to $160,200, which affects future benefit calculations for workers still earning credits.
These thresholds adjust annually and are worth tracking if you're working while receiving SSDI or approaching the point where you plan to attempt a return to work.
SSDI payments for January 2023 reflected the 8.7% COLA increase. Your payment date depends on your birthday and when you began receiving benefits — the SSA pays recipients on the second, third, or fourth Wednesday of each month based on birth date. Those who have been receiving benefits since before May 1997 follow a different schedule.
The SSA typically announces the following year's COLA in October, so recipients can plan ahead.
For SSDI recipients already enrolled in Medicare Part B (most become eligible after a 24-month waiting period from their disability onset date), monthly premiums are typically deducted directly from the benefit. In 2023, Part B premiums actually decreased slightly — from $170.10 to $164.90 per month — which meant recipients got to keep slightly more of their COLA increase than they would have otherwise.
That's notable because in some prior years, Medicare premium increases offset part of the COLA gain.
Every SSDI recipient's 2023 increase was determined by a combination of factors that are entirely individual:
Two people both receiving SSDI in 2023 — both subject to the same 8.7% COLA — could end up with very different net changes once all of these factors are applied to their individual cases.
The 2023 COLA was a significant, well-documented event. How it landed in your bank account each month is a different question entirely — one that depends on the full picture of your benefit record, deductions, and program interactions. 📋
