Every year, Social Security β including SSDI (Social Security Disability Insurance) β adjusts benefit amounts to keep pace with inflation. This adjustment is called the Cost-of-Living Adjustment, or COLA. For 2020, SSA announced a COLA of 1.6%.
That means if you were receiving SSDI benefits in January 2020, your monthly payment increased by 1.6% over what you received in December 2019. The increase applied automatically β no application, no paperwork required.
For most recipients, a 1.6% increase translated to a modest but real bump in monthly income. To understand the range, it helps to know where average payments sat heading into 2020.
The average SSDI benefit for a disabled worker in late 2019 was approximately $1,258 per month. After the 1.6% COLA, that average rose to roughly $1,278 per month β an increase of about $20.
Here's a simple illustration of how 1.6% applies across different benefit levels:
| Monthly Benefit Before COLA | 1.6% Increase | New Monthly Benefit |
|---|---|---|
| $800 | ~$13 | ~$813 |
| $1,000 | ~$16 | ~$1,016 |
| $1,258 (avg.) | ~$20 | ~$1,278 |
| $1,500 | ~$24 | ~$1,524 |
| $2,000 | ~$32 | ~$2,032 |
These are illustrations, not guarantees. Your actual increase depended entirely on your own benefit amount before the adjustment.
It's worth understanding why benefit amounts vary so widely between recipients. Unlike a flat payment, SSDI is calculated based on your lifetime earnings record.
Specifically, SSA uses a formula that looks at your Average Indexed Monthly Earnings (AIME) β a figure derived from your highest-earning years in covered employment β and runs it through a progressive formula to arrive at your Primary Insurance Amount (PIA). That PIA becomes your base monthly SSDI payment.
What this means in practice:
The COLA percentage is the same for everyone β 1.6% in 2020 β but because it's applied to different base amounts, the dollar increase differs from person to person.
The COLA doesn't just affect monthly checks. It also triggers adjustments to other key SSDI-related figures:
Substantial Gainful Activity (SGA): The monthly earnings threshold that determines whether SSA considers you to be working at a level inconsistent with disability status. In 2020, SGA rose to $1,260/month for non-blind individuals (up from $1,220 in 2019) and $2,110/month for blind individuals.
Trial Work Period (TWP) threshold: The monthly earnings amount that counts as a trial work month also adjusts. In 2020, it was set at $910/month.
These figures matter if you're working while receiving SSDI or considering a return to work. If your earnings stay below the SGA threshold, SSA generally does not consider you to be engaged in substantial work activity.
SSDI payments are issued on a schedule tied to your birth date:
The 2020 COLA increase first appeared in January 2020 payments. SSA typically sends a notice in December of the preceding year informing recipients of their new payment amount.
SSI (Supplemental Security Income) is a separate, needs-based program. It also received the 1.6% COLA for 2020, bringing the maximum federal SSI payment to $783/month for individuals and $1,175/month for couples.
Some people receive both SSDI and SSI simultaneously β called concurrent benefits. This happens when someone's SSDI payment is low enough that they still qualify for SSI as a supplement. In those cases, the COLA applied to both components, though SSI is also subject to income and resource limits that can reduce or eliminate payments depending on your situation.
The 2020 COLA of 1.6% is a fixed, public fact. What it meant for any individual recipient β and what SSDI pays in any given year β comes back to a number that's unique to each person: the lifetime earnings record SSA has on file.
Two people who both became disabled in the same year, with the same diagnosis, could receive payments that differ by hundreds of dollars per month. Their medical conditions might look similar on paper, but their AIME calculations β shaped by decades of work history β tell entirely different stories. The percentage increase is the same. The dollar amount it produces is not.
