Understanding how Supplemental Security Income (SSI) benefits are calculated can help you know what to expect — and ensure you receive the right amount each month. The Social Security Administration (SSA) uses a specific formula that considers your income, living situation, and resources.


What Is SSI?

SSI, or Supplemental Security Income, is a federal program that provides monthly payments to people with limited income and resources who are aged 65 or older, blind, or disabled. Unlike Social Security Disability Insurance (SSDI), SSI is need-based, not tied to your work history.


Step 1: Start With the Federal Benefit Rate (FBR)

The SSA sets a Federal Benefit Rate (FBR) each year — this is the maximum monthly SSI payment before any deductions.


2025 FBR Amounts:

  • $943 per month for an individual
  • $1,415 per month for a couple


Some states add supplemental payments, which can increase your monthly benefit.


Step 2: Subtract Countable Income

Your SSI payment is reduced by your countable income — not all income counts, but most types do.


Types of Countable Income

  • Earned income – Wages, self-employment income
  • Unearned income – Pensions, unemployment, or other Social Security benefits
  • In-kind support – Free food or shelter you receive


Income That Doesn’t Count

The SSA excludes certain amounts:

  • The first $20 of most income each month
  • The first $65 of earned income, plus half of the remainder
  • SNAP (food stamps), most home energy assistance, and some one-time payments


Step 3: Factor in Living Arrangements

Where and with whom you live can also affect your SSI payment.

  • Living alone or paying your fair share of expenses usually means you receive the full rate.
  • If someone else pays your housing or food costs, your benefit can be reduced by up to one-third.


Step 4: Consider State Supplements

Many states add their own supplemental payments to SSI. These amounts vary widely and depend on factors like:

  • Your living situation (alone, in a care facility, with family)
  • The state’s cost-of-living adjustments


Step 5: Resource Limits

You must also meet SSI’s resource limits:

  • $2,000 for individuals
  • $3,000 for couples


Resources include things like cash, savings, or property (other than your primary home).


Example Calculation

Let’s say you earn $500/month from part-time work:

  • Subtract $20 general exclusion → $480
  • Subtract $65 earned income exclusion → $415
  • Subtract half of remainder ($207.50) → $207.50 countable income


If you’re eligible for the full federal rate of $943:
$943 – $207.50 = $735.50 monthly SSI payment


Key Takeaways

  • SSI is need-based, not based on past work.
  • Benefits are calculated from the Federal Benefit Rate, minus countable income.
  • State supplements and living arrangements can affect your total.
  • The SSA reviews eligibility regularly, so reporting any income changes is crucial.
