The 2018 SSDI payment amounts

In 2018, the average SSDI payment was $1,182 per month. The highest payment that year was $2,788 per month for workers who had earned the maximum Social Security credits before becoming disabled. The lowest payment was $30 per month, though this applied only in rare circumstances.

These amounts were set by a formula based on your lifetime earnings record, not on need or how severe your disability is. The Social Security Administration recalculates the formula each year using wage data from two years prior. Because 2018 payments were based on 2016 wage records, they reflected economic conditions from that earlier period.

Your actual 2018 payment depended entirely on how much you had earned while working and how long you had worked before becoming disabled. Someone who worked for 40 years at high wages would receive far more than someone who worked for 10 years at lower wages, even if both had the same medical condition.

Key Takeaways

  • The average SSDI payment in 2018 was $1,182 per month, but individual payments ranged from $30 to $2,788 depending on your work history.
  • Your payment amount was determined by your lifetime earnings record, not by the severity of your disability or your current financial need.
  • Social Security used a specific formula to calculate payments, converting your highest 35 years of earnings into a monthly benefit.
  • Payments increased slightly each year through a cost-of-living adjustment, which in 2018 was 2 percent.

How the 2018 payment formula worked

Social Security used three "bend points" to convert your earnings history into a monthly payment. The bend points were dollar amounts that changed each year based on national wage trends. In 2018, the bend points were $898 and $5,397.

The formula took your highest 35 years of earnings, adjusted them for inflation, and averaged them. Then it applied the bend points to that average. The first portion of your average earnings (up to the first bend point) was replaced at 90 percent. The middle portion (between the first and second bend points) was replaced at 32 percent. Everything above the second bend point was replaced at 15 percent. This structure meant that lower earners received a higher percentage of their pre-disability income, while higher earners received a lower percentage.

If you had worked fewer than 35 years, Social Security counted the missing years as zero, which lowered your average and therefore your payment. This is why people who became disabled young often received smaller payments than those who worked longer before becoming disabled.

Cost-of-living adjustments in 2018

In October 2017, Social Security announced a 2 percent cost-of-living adjustment (COLA) that took effect in January 2018. This meant that everyone receiving SSDI in 2018 received 2 percent more than they had in 2017, assuming they were still receiving benefits.

The COLA was based on the Consumer Price Index for Urban Wage Earners and Clerical Workers (CPI-W), which measures inflation across the economy. Congress did not set the COLA amount—it was calculated automatically by a formula tied to inflation data. In years when inflation was very low or negative, the COLA could be zero or even result in no increase.

Differences between 2018 and other years

The 2018 payment amounts were higher than 2017 because of the 2 percent COLA, but lower than 2019 because that year's COLA was 2.8 percent. The average payment in 2017 was approximately $1,160, and in 2019 it rose to approximately $1,234.

The bend points also changed from year to year. In 2017, the first bend point was $885 and the second was $5,336. By 2019, they had shifted to $926 and $5,583. These small annual changes reflected wage growth across the economy and affected how much of your earnings were converted into a payment.

Why your 2018 payment might have been different from the average

The average of $1,182 was just that—an average. Half of all SSDI recipients received more, and half received less. Your actual payment depended on when you became disabled, how long you worked before that, and what you earned during your working years.

Someone who became disabled at age 25 after working for only five years would have received far less than the average, because the formula counted 30 years of zero earnings. Someone who worked until age 60 and then became disabled would likely have received more than the average, because they had 35 years of substantial earnings to draw from.

Your payment also did not change based on your living situation, your other income, or how much money you had in savings. SSDI is not a needs-based program. A disabled person with a trust fund received the same payment as a disabled person with no savings, if their work histories were identical.

What happened to 2018 payments after that year

If you were receiving SSDI in 2018 and remained disabled and on the rolls, your payment increased each January when the new COLA took effect. The 2019 COLA was 2.8 percent, the 2020 COLA was 1.3 percent, and the 2021 COLA was 1.3 percent. These increases compounded over time, so your 2024 payment would be noticeably higher than your 2018 payment.

Your payment could also change if you had a work incentive event, such as returning to work and then stopping again, or if you reached full retirement age and your SSDI converted to retirement benefits at the same rate. But the basic formula—your lifetime earnings converted through the bend points—remained the same throughout your time on SSDI.

Frequently Asked Questions

Was the 2018 SSDI payment amount the same for everyone?

No. The 2018 average was $1,182, but payments ranged from $30 to $2,788 per month. Your individual payment was based on your earnings history, not on your disability or your financial need. Two people with the same medical condition could receive very different payments if they had different work histories.

How did Social Security know what to pay me in 2018?

Social Security looked at your earnings record from the previous 35 years (or fewer if you had worked less than 35 years), adjusted those earnings for inflation, and applied the bend-point formula. The result was your Primary Insurance Amount, which was your monthly payment. This calculation happened automatically when you were approved for SSDI.

Did my 2018 payment include Medicare?

No. The $1,182 average was the cash payment only. After two years of receiving SSDI, you also became covered by Medicare Part A and Part B at no cost. Medicare was separate from your cash payment and did not reduce it.

Could I have received more than $2,788 in 2018?

No. The $2,788 was the maximum SSDI payment in 2018 for a worker who had earned the maximum Social Security credits. You could not receive more than this amount based on your own work record, though family members could receive additional payments on your record if you had dependents.

What if I had worked part-time before becoming disabled?

Your payment would have been lower than someone who worked full-time at the same wage, because the formula averaged your earnings over 35 years. Part-time work meant lower annual earnings, which lowered your average and therefore your payment. Years with no earnings counted as zero in the calculation.
