Every year, Social Security adjusts its benefit payments to keep pace with inflation. For 2023, that adjustment was the largest in four decades — and it affected every person already receiving SSDI, as well as the program's eligibility thresholds. Here's what changed, how the increase was calculated, and why the dollar impact varied from one recipient to the next.
The annual adjustment is called a Cost-of-Living Adjustment, or COLA. The Social Security Administration calculates it using the Consumer Price Index for Urban Wage Earners and Clerical Workers (CPI-W), comparing third-quarter data from the current year to the prior year.
For 2023, the SSA announced an 8.7% COLA — the highest since 1981. That figure was driven by the inflation surge that ran through 2021 and 2022. The increase applied automatically to all SSDI recipients; no action was required to receive it.
The COLA is a percentage applied to each recipient's existing benefit amount — not a flat dollar raise applied equally to everyone. That means the actual dollar increase depended entirely on what a person was already receiving.
| Monthly Benefit Before 2023 | 8.7% COLA Increase | New Monthly Benefit |
|---|---|---|
| $800 | +$70 | ~$870 |
| $1,200 | +$104 | ~$1,304 |
| $1,500 | +$131 | ~$1,631 |
| $1,800 | +$157 | ~$1,957 |
| $2,200 | +$191 | ~$2,391 |
The average SSDI benefit for a disabled worker heading into 2023 was approximately $1,483 per month before the adjustment — putting the average dollar increase at roughly $129 per month. But averages obscure the real range. Some recipients received less than $50 more per month; others saw increases well above $200.
SSDI is not a needs-based program. Your benefit is calculated from your earnings record — specifically, your Average Indexed Monthly Earnings (AIME), which reflects your taxable wages over your working life. The SSA then applies a formula to your AIME to produce your Primary Insurance Amount (PIA), which becomes your monthly benefit.
Because SSDI payments are tied to lifetime earnings rather than current financial need, two people with the same disability can receive very different monthly amounts depending on how long they worked, how much they earned, and at what ages they became disabled.
This also means the COLA increase is inherently unequal in dollar terms: someone with a higher benefit due to a longer, higher-earning work history receives a larger dollar raise than someone with a shorter or lower-wage work history — even though both receive the same 8.7% percentage increase.
The COLA doesn't just affect monthly payments. It also adjusts other figures throughout the SSDI program:
Substantial Gainful Activity (SGA): This is the earnings threshold that determines whether someone is working "too much" to qualify for or maintain SSDI. For 2023, the SGA limit rose to $1,470 per month for non-blind individuals (up from $1,350 in 2022) and $2,460 per month for statutorily blind individuals. Earning above SGA can affect both eligibility and continued benefits.
Trial Work Period (TWP) threshold: For recipients testing their ability to return to work, the monthly earnings amount that counts as a trial work month increased to $1,050 in 2023.
Maximum SSDI benefit: The highest possible SSDI payment also increased, though relatively few recipients reach that ceiling. The theoretical maximum for a high-earning worker is well above the average — but reaching it requires a long, high-wage work history before disability onset.
It's worth clarifying: SSDI and SSI are different programs, though both are administered by the SSA and both received the 2023 COLA. SSI (Supplemental Security Income) is needs-based and not tied to work history. The federal SSI payment limit rose to $914 per month for individuals and $1,371 for couples in 2023.
Some people receive both SSDI and SSI simultaneously — called concurrent benefits — when their SSDI payment falls below SSI's income thresholds. The COLA applied to both components in those cases, though the interaction between the two programs affects how much of each increase a concurrent recipient actually keeps. 🔍
The 2023 COLA took effect with January 2023 benefit payments. For most SSDI recipients, payment arrives on a Wednesday based on the day of birth:
Recipients who have been on SSDI since before May 1997 follow a different schedule and generally receive payments on the 3rd of each month.
A significant increase in COLA does not affect several key aspects of SSDI:
Understanding the 8.7% figure is straightforward. What's less predictable is the number it gets applied to — and that number comes from a lifetime of earnings, the age at which disability began, whether someone is also receiving SSI, and how the SSA's benefit formula weighted their particular work record.
Two people sitting in the same room, both on SSDI, both affected by the same 8.7% COLA, likely saw very different changes to their monthly income in January 2023. The percentage is public and fixed. The base it's multiplied against is entirely individual.
