Social Security SSI Benefit Calculator

The foundation of any SSI calculation is the Federal Benefit Rate (FBR). This is the maximum possible amount the federal government will pay an eligible person each month. Your actual benefit is the FBR minus your "countable income."

The Social Security Administration adjusts these figures annually based on inflation. If you want to understand how these increases are calculated, read about how the Social Security COLA is explained.

Note: Many states provide a supplemental payment on top of the federal base rate. This calculator estimates the federal portion of your benefit. If you live in a state that supplements SSI, your total monthly payment may be higher.

The Social Security Administration treats money you work for differently than money you passively receive. The SSI program is designed to encourage recipients to work if they are able, so it penalizes unearned income much more heavily than earned income.

Unearned Income (Reduces Benefits Almost Dollar-for-Dollar)

Unearned income includes any cash you receive that does not come from current work. Common examples include standard Social Security retirement benefits, defined benefit pension payments, unemployment benefits, interest, dividends, or cash gifts from family members.

When calculating your SSI benefit, the SSA only ignores the first $20 of your unearned income each month (the General Income Exclusion). After that $20, every single dollar of unearned income reduces your SSI benefit by exactly one dollar. For example, if you receive a $500 monthly pension, $480 of it is "countable," meaning your SSI check will be reduced by $480. If you are expecting a sudden influx of cash, such as a Social Security lump sum, it can completely disqualify you from SSI for the month it is received.

Earned Income (Treated Favorably)

Earned income includes wages from a job or net earnings from self-employment. The SSA applies a much more generous formula to money you earn:

1. First, if you haven't used your $20 General Income Exclusion on unearned income, you can apply it to your earned income.
2. Next, you get a $65 Earned Income Exclusion.
3. Finally, the SSA only counts half of the remaining earned income.

Because of this "divide by two" rule, you can earn significantly more from working before your SSI benefit is reduced to zero.

One of the most complex rules in the SSI program is how it treats non-cash support. If you live rent-free with a relative, or if someone else pays for your groceries and utilities, the SSA considers this "In-Kind Support and Maintenance" (ISM).

Because SSI is intended to cover basic food and shelter needs, receiving these items for free means you have less financial need. If the SSA determines you receive ISM, they apply the Value of the One-Third Reduction (VTR) rule.

This rule automatically reduces your maximum Federal Benefit Rate by exactly one-third.

• For an individual in 2026, the $991 base rate drops by roughly $330, leaving an adjusted maximum of $661.
• For a couple, the $1,487 base rate drops by roughly $495, leaving an adjusted maximum of $992.

This one-third reduction applies regardless of the actual dollar value of the rent or food you received. Whether your child lets you stay in a $3,000-a-month apartment for free or a $500-a-month basement, the penalty is the same one-third reduction to your base rate.

To determine your exact monthly payment, the calculator applies a specific sequence of exclusions to your gross income.

The calculator applies this primary formula to determine your base rate:

Adjusted FBR = Base FBR × (1 - ISM Reduction Factor)

Where:

• Adjusted FBR = Your maximum possible payment before income deductions.
• Base FBR = The standard federal rate ($991 for an individual, $1,487 for a couple).
• ISM Reduction Factor = 33.3% (or 1/3) if you receive free food and shelter, otherwise 0%.

Next, the calculator determines how much of your unearned income counts against you:

Countable Unearned Income = Max(0, Gross Unearned Income - General Income Exclusion)

Where:

• Gross Unearned Income = Pensions, gifts, or standard Social Security benefits.
• General Income Exclusion = $20 per month.

Then, it calculates your countable earned income, applying any leftover general exclusion:

Countable Earned Income = Max(0, Gross Earned Income - Remaining GIE - Earned Income Exclusion) ÷ 2

Where:

• Gross Earned Income = Your wages or self-employment profit.
• Remaining GIE = Any portion of the $20 exclusion not used on unearned income.
• Earned Income Exclusion = $65 per month.
• ÷ 2 = The rule that only half of remaining earnings are counted.

Finally, your actual monthly benefit is calculated by subtracting all countable income from your adjusted rate:

Estimated Monthly Benefit = Max(0, Adjusted FBR - (Countable Earned Income + Countable Unearned Income))

While this calculator focuses on the income rules for SSI, your assets (resources) are just as critical. You can have zero income and still be denied SSI if you have too much money in the bank.

To qualify for SSI, your countable resources must not exceed:

• $2,000 for an individual
• $3,000 for a couple

What Counts as a Resource? Cash, bank accounts, stocks, mutual funds, U.S. savings bonds, land, and any vehicles beyond your primary car all count toward your limit. If you are trying to figure out how long your money will last, be aware that spending down assets to qualify for SSI must be done carefully to avoid "transfer of asset" penalties.

What Does NOT Count as a Resource? The SSA excludes certain essential items from the $2,000/$3,000 limit. These include:

• The home you live in and the land it sits on.
• One vehicle, regardless of its value, if it is used for transportation for you or a household member.
• Household goods and personal effects (furniture, jewelry).
• Life insurance policies with a combined face value of $1,500 or less.
• Burial plots for you and your immediate family.
• Up to $100,000 in an ABLE (Achieving a Better Life Experience) account, if you became disabled before age 26.

Many people confuse Supplemental Security Income (SSI) with standard Social Security retirement or Social Security Disability Insurance (SSDI). While the Social Security Administration manages all three programs, they have entirely different rules.

If you have a work history but want to retire before your Full Retirement Age, you should evaluate the Social Security early retirement calculator rather than relying on SSI. If you are married, you may also be eligible for benefits on your spouse's work record, which you can estimate using the spousal Social Security calculator.

What is the difference between SSI and SSDI?

SSI (Supplemental Security Income) is a needs-based program for low-income individuals who are aged, blind, or disabled, regardless of their work history. SSDI (Social Security Disability Insurance) is an entitlement program for disabled workers who have paid enough Social Security taxes over their career. SSDI payment amounts are based on your past earnings, while SSI payments are based on your current financial need.

Who qualifies for SSI in 2026?

To qualify, you must be at least 65 years old, blind, or have a qualifying medical disability. Additionally, you must meet the strict financial requirements: your countable income must be lower than the Federal Benefit Rate ($991 for an individual), and your total countable resources must stay under $2,000 for a single person or $3,000 for a couple.

Are SSI benefits taxable?

No. Supplemental Security Income payments are never subject to federal or state income taxes. Unlike standard Social Security benefits, which can be partially taxed if your combined income is high enough, SSI is a welfare benefit and is entirely tax-free.

Can I receive both SSI and regular Social Security at the same time?

Yes, this is called receiving "concurrent benefits." However, your standard Social Security check is counted as unearned income for SSI purposes. After the $20 general exclusion, every dollar of your regular Social Security benefit reduces your SSI benefit by a dollar. If you are trying to maximize two different Social Security income streams, you may want to look into a Social Security leveling calculator or read our guide on whether you can live on Social Security alone.

Does my spouse's income affect my SSI?

Yes. If you are married and living with a spouse who does not qualify for SSI, the SSA uses a process called "deeming." They assume a portion of your ineligible spouse's income and resources are available to you, which can reduce or eliminate your SSI benefit.

What happens if I save too much money while on SSI?

If your bank account balance pushes your total countable resources over the $2,000 individual limit at the beginning of a calendar month, your SSI benefits will be suspended for that month. If you remain over the limit for 12 consecutive months, your SSI eligibility is terminated, and you will have to reapply from scratch once your assets drop below the threshold.

How do I report my income to the SSA?

If you receive SSI, you are required to report your wages at the beginning of every month (usually by the 6th). You can report income using the SSA's mobile app, via an automated telephone system, or by bringing pay stubs to your local Social Security office. Failing to report income can result in overpayments that the SSA will force you to pay back.

SSI is a vital lifeline, but because the payments are designed merely to keep recipients at the poverty line, it is difficult to rely on it as a sole source of retirement income. If you are still working, explore ways to build your own savings or maximize your standard benefits.

To map out your long-term timeline, use the Social Security life expectancy calculator to see how many years of income you need to plan for. If you have a standard work history, read our guide on when to take Social Security: 62 vs 67 vs 70 to understand how claiming age impacts your lifetime payout.
