Your benefit amount depends on your earnings history, not your disability

Social Security Disability Insurance (SSDI) pays you a monthly amount based on how much you earned before you became unable to work—not on how severe your disability is or how much you need. The Social Security Administration calculates this from your Primary Insurance Amount (PIA), which is tied to your average lifetime earnings.

The actual dollar amount you receive changes each year because Social Security adjusts all benefits for inflation. In 2024, the average SSDI payment was around $1,550 per month, but this varies widely. Someone who worked at minimum wage their whole life will receive less than someone who earned significantly more, even if both have the same disability.

Your family members may also receive benefits based on your earnings record—your spouse, ex-spouse, and children under 19 (or 22 if still in high school) can each draw a portion. This does not reduce your payment, but it does mean the total amount paid to your household comes from a family maximum, which is usually 150 to 180 percent of your PIA.

Key Takeaways

  • Your SSDI payment is calculated from your average earnings before disability, not from the severity of your condition or your current expenses.
  • Social Security adjusts all payments yearly for inflation, so the amount you receive in 2025 will differ from 2024.
  • Family members can receive benefits on your record, but the total household payment is capped at a family maximum that Social Security sets.
  • You can request a benefit estimate from Social Security before you file, using your online account or by calling 1-800-772-1213.
  • Once approved, your first payment arrives the month after your may be able to access month, and the amount stays the same each month unless Social Security adjusts it for inflation.

How Social Security calculates your Primary Insurance Amount

Social Security looks at your 35 highest-earning years (or fewer if you have not worked that long) and calculates your average monthly earnings. They then explore a formula that weights lower earnings more heavily than higher earnings. This means the benefit formula replaces a larger percentage of income for lower earners than for higher earners.

The exact formula changes each year because Social Security adjusts the dollar amounts in the formula to account for wage growth. For 2024, the formula used bend points of $1,174 and $7,078—these are the thresholds where the replacement percentage changes. If your average monthly earnings fall below the first bend point, you receive 90 percent of that amount. Between the first and second bend point, you receive 32 percent. Above the second bend point, you receive 15 percent.

If you did not work for 35 years, Social Security counts the missing years as zero earnings. This lowers your average and reduces your benefit. If you worked fewer than 10 years total, you do not meet the work requirement for SSDI and cannot receive benefits based on your own record.

What happens to your payment if you work while receiving SSDI

If you earn money while on SSDI, Social Security does not automatically reduce your benefit—but there are limits. During your first nine months of work after approval (called the Trial Work Period), you can earn any amount without losing benefits. After those nine months, Social Security counts only months where you earn more than $950 per month (in 2024) toward a 36-month window.

Once you have used your 36 months of countable work, Social Security applies the Substantial Gainful Activity (SGA) limit. In 2024, SGA is $1,550 per month. If you earn more than this in any month, Social Security stops your benefit for that month. The SGA amount increases each year with inflation.

This system is designed to let you test whether you can work without when ready losing all support. Many people use the Trial Work Period to see if their condition allows sustained employment. If you return to work and your earnings exceed SGA, you can request a new SSDI review if your condition worsens again.

How family members' benefits are calculated

If you have a spouse, ex-spouse, or children, they can each receive a benefit based on your earnings record. A spouse or ex-spouse at full retirement age receives 50 percent of your PIA. A spouse under full retirement age receives less—the exact amount depends on how many months before their full retirement age they claim. Children under 19 (or 22 if in high school) each receive 75 percent of your PIA.

The family maximum limits the total amount paid to all family members combined. This maximum is usually 150 to 180 percent of your PIA, depending on your specific situation. If the sum of all family members' benefits exceeds this maximum, Social Security reduces each person's payment proportionally so the total does not go over the cap. Your own benefit is never reduced because of the family maximum—only the family members' portions are adjusted.

A child's benefit stops the month they turn 19 (or 22 if in high school). A spouse's benefit continues as long as they remain married to you or until they reach full retirement age and claim their own benefit instead.

Cost-of-living adjustments and how they affect your payment

Every year in October, Social Security announces a Cost-of-Living Adjustment (COLA) that increases all SSDI payments. This adjustment is based on inflation measured by the Consumer Price Index. In years with low inflation, the COLA is small or zero. In years with high inflation, the COLA is larger.

The COLA applies to your PIA and all family members' benefits at the same time. If you received $1,500 in January and Social Security announces a 3 percent COLA, your payment in January of the following year will be approximately $1,545. The new amount becomes effective in December of the prior year, though you receive it in January.

You do not need to do anything to receive the COLA—it happens automatically. Social Security notifies you of the new amount in December, and the increased payment appears in your account in January.

How to find out what you might receive before you file

Social Security offers a benefit estimate tool on its website at ssa.gov. You can create a my Social Security account, which shows your earnings history and provides an estimate of your SSDI benefit based on your current record. This estimate assumes you become unable to work at your current age and is updated each year.

The estimate is not a may provide of what you will receive—it is based on your earnings record as Social Security has it on file. If there are errors in your record (missing years, incorrect amounts), the estimate will be wrong. You can review your earnings history in your account and report any discrepancies to Social Security.

If you do not have an online account, you can call Social Security at 1-800-772-1213 and request a benefit estimate by mail. This takes about two weeks. You can also visit a local Social Security office in person, though wait times are often long.

What you receive after you are approved for SSDI

Once Social Security approves your claim, your first payment arrives the month after your may be able to access month. If Social Security determines you became unable to work in June, your first payment covers July and arrives in August. The payment goes directly to your bank account via direct deposit—Social Security no longer issues checks.

Your monthly payment stays the same each month unless Social Security adjusts it for a COLA or unless your circumstances change significantly (such as a return to work that triggers SGA rules). You do not reapply each year; your benefit continues as long as you remain unable to work and meet other requirements, such as not earning above the SGA limit.

If you have questions about your specific payment amount, you can log into your my Social Security account, call 1-800-772-1213, or visit a local office. Social Security can explain how your PIA was calculated and answer questions about family benefits or work-related reductions.

Frequently Asked Questions

Can I find out my exact SSDI payment amount before I file?

No—Social Security can only estimate based on your current earnings record. The exact amount depends on the month Social Security determines your disability began, which is decided during the review process. Your estimate will be close, but the final payment may differ by $50 to $200 depending on the specific may be able to access month.

Will my SSDI payment change if I get married or divorced?

Your own payment does not change, but a spouse or ex-spouse may become able to claim benefits on your record. If you marry, your new spouse can claim at full retirement age or later. If you divorce, your ex-spouse can claim if the marriage lasted at least 10 years and they are at least 62 years old.

What is the difference between SSDI and SSI payments?

SSDI is based on your earnings history and has no income or asset limits. Supplemental Security Income (SSI) is a needs-based program for people with low income and assets, regardless of work history. SSI payments are usually lower and have strict limits on how much money you can have.

Do I have to pay taxes on my SSDI benefits?

It depends on your total income. If SSDI is your only income, you typically do not owe federal income tax. If you have other income (wages, pensions, investment income), up to 85 percent of your SSDI benefits may be taxable. You can request a Social Security form to help calculate this.

What happens to my payment if I move to another country?

SSDI payments continue in most countries, but some countries have restrictions. You must notify Social Security before you move. Certain countries have no agreement with the United States, and payments may stop. Contact Social Security before moving to confirm your benefits will continue.
