What an SGA calculator does and why you need one

An SGA calculator is a tool that shows you whether your monthly earnings are below the dollar amount Social Security uses to decide if you are still disabled. Social Security calls this amount the "substantial gainful activity" limit. If you earn more than this limit in a month, Social Security may decide you are working too much to receive SSDI payments that month.

The limit changes every year. For 2024, the SGA limit for non-blind adults is $1,550 per month. For blind adults, it is $2,590 per month. These numbers will be different in 2025 and beyond. An SGA calculator lets you plug in your actual earnings and see when ready whether you are under the limit, rather than doing the math yourself or calling Social Security to ask.

You do not need a calculator to understand the basic rule: if you earn less than the monthly limit, Social Security will not stop your SSDI payments based on work. If you earn more, your case goes into a review process. But a calculator helps you track your earnings month by month, especially if your income changes or you are testing whether part-time work is safe.

Key Takeaways

  • The SGA limit for non-blind adults in 2024 is $1,550 per month; for blind adults it is $2,590 per month, and both amounts increase each year.
  • You can use Social Security's official SGA calculator on their website, or track your earnings yourself by comparing your gross monthly income to the current year's limit.
  • The calculator shows your earnings for a single month, not your average over time, so you need to check it for each month you work.
  • Earnings include wages, net self-employment income, and certain other forms of income, but do not include some benefits like food stamps or housing information.
  • If you go over the limit in one month, Social Security does not automatically stop your payment — your case enters a medical review, but you may still receive benefits if you remain disabled.

Where to find Social Security's official SGA calculator

Social Security publishes an SGA calculator on its website at ssa.gov. You can search for "SGA calculator" or navigate to the "Earnings" section under "Working While Disabled." The official tool is free and does not require you to create an account or provide personal information.

The calculator asks you to enter your gross monthly earnings and select whether you are blind or non-blind. It then tells you whether you are under or over the limit for that month. Some versions also show you the current year's limit and let you see what the limit will be in future years.

You can also find the SGA limit posted on ssa.gov without using a calculator — Social Security updates the dollar amount every January. If you prefer to do the math yourself, you straightforward compare your gross monthly earnings to the posted limit. The calculator is a convenience, not a requirement.

What counts as earnings in the SGA calculation

Gross wages from a job count toward the SGA limit. This is the amount before taxes, insurance, or other deductions. If you earn $1,600 in gross wages in a month, that $1,600 counts, even if your take-home pay is lower.

Net self-employment income also counts. If you run your own business, Social Security counts your profit (revenue minus business expenses) toward the limit. You will need to track your income and expenses carefully if you are self-employed.

Other forms of income that count include certain types of work incentive payments and sheltered workshop earnings. Income that does not count includes Supplemental Security Income (SSI), food stamps, housing information, tax refunds, and money from family members that is not payment for work you did.

Social Security also has special rules for certain work situations. If you are in a trial work period or using a work incentive like Impairment Related Work Expenses (IRWE), the way earnings are counted may be different. The official calculator does not account for these special rules, so you may need to contact Social Security directly if you are using a work incentive.

How the calculator handles month-to-month changes in income

The SGA calculator works one month at a time. You enter your earnings for January, and it tells you whether you are under the limit for January. Then you enter your earnings for February, and it tells you about February. Social Security does not average your earnings across several months or look at your total yearly income.

This matters if your income varies. You might earn $1,200 in January (under the limit), $1,800 in February (over the limit), and $1,300 in March (under the limit). Each month stands on its own. You would use the calculator three times, once for each month.

If you go over the limit in one or more months, Social Security will review your case. But going over the limit in a single month does not automatically end your SSDI. Social Security looks at whether you remain disabled and may continue your benefits even if you earned above the limit in some months. The calculator shows you the threshold; it does not predict what Social Security will decide about your ongoing benefits.

Understanding the difference between the SGA limit and work incentives

The SGA limit is a threshold, not a rule about whether you can work. It is the point at which Social Security begins to question whether you are still disabled. But Social Security also offers work incentives that let you earn above the SGA limit and still receive some or all of your SSDI payment.

The most common work incentive is the trial work period, which lets you work and earn any amount for nine months without affecting your SSDI payment. After the trial work period ends, a different rule called the extended may be able to access period allows you to continue receiving SSDI for up to 36 months while you are working, even if you earn above the SGA limit.

Other work incentives include Impairment Related Work Expenses (IRWE), which lets you subtract certain disability-related costs from your earnings before Social Security counts them toward the SGA limit. The SGA calculator does not include these adjustments. If you are using a work incentive, you need to report it to Social Security and may need to do your own math or ask Social Security to calculate your benefit amount.

What happens if you go over the SGA limit

If your earnings exceed the SGA limit in a month, you do not lose your SSDI payment when ready. Instead, Social Security will contact you to review your case. They will ask about your work, your medical condition, and whether you believe you remain disabled.

Social Security may decide that you are still disabled and continue your benefits, even though you earned above the limit. They may also decide that your work shows you are no longer disabled and stop your payments. Or they may place you in an extended may be able to access period or another work incentive program that lets you keep working and receiving benefits.

The key point is that exceeding the SGA limit triggers a review, not an automatic termination. Many people go over the limit and continue to receive SSDI. The calculator shows you the threshold; it does not predict the outcome of a review.

Tracking your earnings throughout the year

If you work while receiving SSDI, it is a good idea to track your monthly earnings and check them against the SGA limit regularly. You can use the official calculator, a spreadsheet, or straightforward write down your gross earnings each month and compare them to the posted limit.

Keep records of your pay stubs or invoices so you can show Social Security your actual earnings if they ask. If your earnings change or you start a new job, recalculate right away. This helps you stay aware of where you stand and gives you time to contact Social Security if you have questions.

Remember that the SGA limit increases each January. If you are working in December and earning close to the limit, your earnings might be under the limit in January even if your pay stays the same, because the limit will have gone up. Check the new limit each year.

Frequently Asked Questions

Does the SGA calculator tell me if I will lose my SSDI?

No. The calculator only shows whether your earnings are above or below the SGA limit for a given month. Going over the limit means Social Security will review your case, but it does not mean you will lose your benefits. Many people earn above the SGA limit and continue to receive SSDI.

What if I am self-employed — how do I calculate my earnings?

Social Security counts your net self-employment income, which is your total business income minus your business expenses. You will need to track both carefully. If you are unsure how to calculate net income, ask Social Security or a tax professional before you enter the number into the calculator.

Do I need to report my earnings to Social Security before I use the calculator?

No. The calculator is a tool for you to understand the SGA limit. You are required to report your earnings to Social Security separately, usually through a form called the SSA-777 or by phone. The calculator does not report anything for you.

Will the SGA limit be the same next year?

No. Social Security increases the SGA limit every January based on changes in the national average wage. The 2024 limit for non-blind adults is $1,550, but the 2025 limit will be higher. Check ssa.gov in January each year to see the new limit.

Can I use the calculator if I am receiving SSI instead of SSDI?

The SGA calculator is designed for SSDI recipients. SSI has different rules and different income limits. If you receive SSI, contact Social Security directly to ask about how your earnings affect your benefits.
