Your monthly payment depends on your work history and earnings, not on how disabled you are

Social Security Disability Insurance (SSDI) pays you based on how much you earned before you stopped working, not based on the severity of your condition. The Social Security Administration calculates your Primary Insurance Amount (PIA) — the monthly benefit you receive — by looking at your 35 highest-earning years. If you worked fewer than 35 years, zeros are counted for the missing years, which lowers your benefit.

Your payment can range from roughly $100 to over $3,800 per month, depending on your earnings record. The exact amount is determined by a formula that Social Security applies to your average indexed monthly earnings. You cannot change this amount by appealing your medical decision or by proving you need more money — the formula is fixed once your benefit is calculated.

If you are married or have dependent children, they may also receive payments based on your earnings record. A spouse or ex-spouse age 62 or older can receive up to 50 percent of your benefit. Each child under 19 (or 19 if still in high school) can receive up to 75 percent of your benefit. However, there is a family maximum: the total paid to you and all family members cannot exceed 150 to 180 percent of your Primary Insurance Amount.

Key Takeaways

  • Your monthly SSDI payment is based on your earnings history, not on how disabled you are or how much money you need.
  • Social Security uses your 35 highest-earning years to calculate your benefit; years you did not work count as zeros.
  • Family members — spouses, ex-spouses, and children — may receive payments based on your earnings record, but the total family benefit has a cap.
  • You can see your estimated benefit amount by creating a my Social Security account and viewing your earnings record before you file.

How Social Security calculates your monthly amount

Social Security takes your average earnings over your 35 highest-earning years and adjusts them for inflation using a process called indexing. The result is your Average Indexed Monthly Earnings (AIME). Social Security then applies a formula called the bend points formula to your AIME to arrive at your Primary Insurance Amount.

The bend points formula replaces a higher percentage of your earnings if you earned less, and a lower percentage if you earned more. For example, in 2024, Social Security replaces 90 percent of the first $1,174 of your AIME, 32 percent of earnings between $1,174 and $7,078, and 15 percent of earnings above $7,078. These dollar amounts (called bend points) change each year based on national wage trends.

Because the formula is progressive, a person who earned $20,000 per year will receive a higher percentage of their earnings than a person who earned $80,000 per year. However, the person who earned more will still receive a higher monthly payment in absolute dollars.

What your earnings record includes and how to check it

Your earnings record is the list of all wages you reported to Social Security through payroll taxes (FICA). Self-employment income also counts if you paid self-employment tax. Earnings from informal work, cash jobs, or work where taxes were not withheld do not appear on your record unless you reported them yourself.

You can view your earnings record by creating a free account at ssa.gov/myaccount. Log in, select "Earnings Record," and review each year. Check for missing years, years with unusually low earnings, or years where your employer may have reported your income incorrectly. If you spot an error, you can request a correction, but you must do so within three years, three months, and 15 days of the year the wages were earned.

Your my Social Security account also shows an estimate of your future SSDI benefit based on your current earnings record. This estimate assumes you continue working until your full retirement age. The estimate updates each year after Social Security posts your new earnings.

How family members' payments are calculated

If you are receiving SSDI, your spouse or ex-spouse (if the marriage lasted at least 10 years) can receive a payment equal to up to 50 percent of your Primary Insurance Amount, provided they are age 62 or older. A younger spouse caring for your child under age 16 can also receive up to 50 percent of your benefit.

Each of your unmarried children under age 19 (or 19 if still in high school full-time) can receive up to 75 percent of your Primary Insurance Amount. Disabled adult children can receive benefits for life if their disability began before age 22, regardless of their current age.

The family maximum limits the total amount paid to your entire household. The maximum is usually between 150 and 180 percent of your Primary Insurance Amount, though the exact percentage varies by state. If the sum of all family members' benefits exceeds the maximum, Social Security reduces each person's payment proportionally. Your own benefit is never reduced; only family members' payments are affected.

When your benefit amount changes

Your SSDI payment increases each year if there is a Cost of Living Adjustment (COLA). Social Security announces the COLA in October for the following year, and the increase takes effect in January. The COLA is based on inflation measured by the Consumer Price Index for Urban Wage Earners and Clerical Workers (CPI-W). In years with no inflation, there is no COLA.

Your benefit can also change if you return to work and earn above the Substantial Gainful Activity (SGA) level. In 2024, SGA is $1,550 per month for non-blind individuals and $2,590 for blind individuals. If you earn more than this amount, Social Security may determine that you are no longer disabled and stop your benefits. However, you have a trial work period of nine months during which you can earn any amount without losing benefits, and a subsequent extended may be able to access period of 36 months during which you can test your ability to work.

Your benefit may also change if you report a change in your living situation, such as moving in with someone who helps pay your expenses, or if you become may have access to to another benefit (such as retirement or workers' compensation) that affects your SSDI payment.

How SSDI differs from SSI payments

Supplemental Security Income (SSI) is a separate program that pays based on financial need, not work history. SSI payments are the same for everyone in a given state — typically between $900 and $950 per month in 2024, though amounts vary by state. SSI is means-tested, meaning your payment is reduced or eliminated if you have income or resources above the limit.

SSDI, by contrast, has no resource limit and no income limit (except the SGA threshold for work earnings). You can own a house, a car, and have savings without affecting your SSDI benefit. You can also receive SSDI and SSI at the same time if you meet the requirements for both programs, though your total payment is capped at the SSI maximum for your state.

Some people receive SSDI based on their own work history and also receive a reduced SSI payment to bring their total to the state maximum. Others receive only SSDI. The program you receive depends on whether you have enough work credits and earnings history to may have access to for SSDI.

Frequently Asked Questions

Can I see what my SSDI payment will be before I file?

Yes. Create a my Social Security account at ssa.gov/myaccount, log in, and select "Retirement Estimator" or view your earnings record. The site will show an estimate of your SSDI benefit based on your current earnings history. The estimate assumes you continue working until your full retirement age, so the actual amount may differ if you stop working sooner.

Why is my SSDI payment lower than my spouse's?

SSDI payments are based on individual earnings records. If you earned less over your lifetime than your spouse did, your Primary Insurance Amount will be lower. Your spouse's family benefit (if they receive one) is calculated as a percentage of their own Primary Insurance Amount, not yours.

What happens to my payment if I go back to work?

If you earn more than the SGA threshold ($1,550 per month in 2024 for non-blind individuals), Social Security may determine you are no longer disabled and stop your benefits. However, you have a nine-month trial work period during which you can earn any amount without losing benefits, and a 36-month extended may be able to access period to test your ability to work.

Does my SSDI payment increase if I have a child?

Your own SSDI payment does not increase. However, your child may be may have access to to receive a separate payment based on your earnings record. Each child under 19 (or 19 if in high school) can receive up to 75 percent of your Primary Insurance Amount, subject to the family maximum.

Can I receive both SSDI and retirement benefits?

No. SSDI converts to retirement benefits at your full retirement age, and the payment amount remains the same. You do not receive both simultaneously. If you are may have access to to retirement benefits based on a spouse's or ex-spouse's record, Social Security will pay the higher of the two amounts.
