Monthly SNAP amounts depend on your household income and expenses

The amount a family of three receives in SNAP benefits is not a fixed number. The U.S. Department of Agriculture calculates it based on your household's net monthly income — what you earn after certain deductions — and subtracts it from a maximum benefit amount. The maximum benefit for a family of three in 2024 is $939 per month, but most families receive less because their income reduces the amount.

The actual calculation works like this: SNAP takes 30 percent of your net monthly income and subtracts it from the maximum. If that number is negative, you get the maximum. If it is positive, that is what you receive. For example, a family of three with a net income of $1,500 per month would receive roughly $489 in benefits ($1,500 × 0.30 = $450; $939 − $450 = $489).

Your net income is not the same as your gross income. The program allows you to subtract certain costs: a standard deduction that varies by state (between $184 and $284 per month), child care expenses, medical costs for elderly or disabled household members, and shelter costs above 50 percent of your remaining income. These deductions lower your net income, which raises your benefit amount.

Key Takeaways

  • The maximum SNAP benefit for a family of three is $939 per month in 2024, but your actual amount depends on your household income and allowable deductions.
  • SNAP calculates your benefit by taking 30 percent of your net monthly income and subtracting it from the maximum — the higher your deductions, the lower your net income and the higher your benefit.
  • Deductible expenses include a standard deduction (set by your state), child care, medical costs for elderly or disabled members, and shelter costs above half your remaining income.
  • Income limits for a family of three are roughly $2,500 to $2,700 gross per month depending on your state, but deductions can raise the threshold at which you stop receiving benefits.

How the standard deduction and shelter costs affect your benefit

Two deductions have the biggest impact on what your family receives: the standard deduction and shelter costs. The standard deduction is a flat amount your state allows you to subtract from your gross income before SNAP calculates your benefit. In 2024, this ranges from $184 to $284 per month depending on which state you live in. This deduction exists because SNAP recognizes that all households have baseline expenses.

Shelter costs — rent, mortgage, property tax, utilities, and home insurance — are deducted only if they exceed 50 percent of your income after other deductions are applied. This is called the shelter deduction cap. For example, if your net income after the standard deduction is $1,000, and your rent is $700, your shelter deduction would be $200 ($700 − $500, which is 50 percent of $1,000). This $200 comes off your income before the 30 percent calculation, lowering your benefit amount further.

If you have high shelter costs relative to your income, this deduction can significantly reduce your benefit. A family of three paying $900 in rent on a $1,500 gross income will see a much larger shelter deduction than a family paying $600 rent on the same income.

Income limits and what counts as income

SNAP has both a gross income limit and a net income limit. For a family of three, the gross income limit is roughly $2,500 to $2,700 per month depending on your state — this is before deductions. However, because deductions lower your net income, you may still be within the program even if your gross income is slightly above this threshold.

Income includes wages from employment, self-employment earnings, Social Security, unemployment benefits, child support, and most other regular payments. It does not include food information itself, certain education benefits, or some types of in-kind support. If you receive irregular income — seasonal work, bonuses, or one-time payments — SNAP averages it over the months you receive it.

Unearned income like Social Security or child support counts the same as wages. If a family of three has one person earning $1,800 per month and another receiving $400 in child support, that is $2,200 in total countable income for the month.

How work expenses and child care reduce your income

If someone in your household works, you can deduct certain costs from your income. Work-related child care — the cost of caring for a child while you work — is fully deductible, with no upper limit. This can significantly lower your net income and raise your benefit. If you pay $300 per month for child care, that full amount comes off your income before SNAP calculates your benefit.

Other work expenses are more limited. Costs like uniforms, tools, or transportation to work are not deductible under SNAP rules. However, if you are self-employed, you can deduct reasonable business expenses — supplies, equipment, rent for a workspace — though you must document them. The key is that the expense must be directly tied to earning that income.

For a family of three where one parent works and pays $250 per month for child care, that deduction alone could raise your monthly benefit by roughly $75 to $80, since it reduces the income that SNAP uses in its 30 percent calculation.

Medical deductions for elderly or disabled household members

If your household includes someone who is elderly (age 60 or older) or disabled, you can deduct their medical expenses from your income. This includes doctor visits, prescription medications, medical equipment, and health insurance premiums. Unlike child care, there is a threshold: you must have at least $35 in monthly medical expenses before any deduction applies, and only the amount above $35 is deductible.

For example, if a household member has $120 in monthly medical costs, you can deduct $85 ($120 − $35). This deduction can add up quickly if someone has ongoing prescriptions or regular medical appointments. A family of three with a disabled member paying $150 per month in medical expenses would deduct $115, which could raise their benefit by $35 per month.

You will need to document these expenses — receipts, insurance statements, or pharmacy records — when you report them. SNAP does not require you to submit them upfront, but you should keep them in case the program asks for verification.

Examples of what three different families might receive

Family A: Gross income $1,200 per month (one part-time job), no deductible expenses beyond the standard deduction of $200. Net income: $1,000. Benefit: $939 − ($1,000 × 0.30) = $939 − $300 = $639 per month.

Family B: Gross income $1,800 per month (one full-time job), pays $400 per month in child care. Standard deduction $200. Net income: $1,800 − $200 − $400 = $1,200. Benefit: $939 − ($1,200 × 0.30) = $939 − $360 = $579 per month.

Family C: Gross income $2,000 per month, pays $900 in rent, standard deduction $200. After standard deduction, income is $1,800. Shelter deduction applies: $900 − ($1,800 × 0.50) = $900 − $900 = $0 (no shelter deduction because rent equals 50 percent). Net income: $1,800. Benefit: $939 − ($1,800 × 0.30) = $939 − $540 = $399 per month.

When your benefit changes and how to report income changes

Your SNAP benefit is recalculated each month based on the income and expenses you report. If your household income increases, your benefit decreases. If it decreases, your benefit increases. You are required to report changes in income, household size, or living situation within 10 days in most states, though some states allow up to 30 days.

Failing to report a change can result in an overpayment — receiving more than you are may have access to to — which you may have to repay. If your income drops, reporting it quickly means your benefit increases sooner. If you start a new job or lose one, contact your local SNAP office or report the change through your state's online portal.

Some states use a simplified reporting system where you report income once every 12 months instead of monthly. Check with your state's SNAP program to learn whether you report monthly or annually and what method your state uses.

Frequently Asked Questions

Does the maximum benefit amount change every year?

Yes. The USDA adjusts the maximum benefit each October based on inflation. The amount for a family of three in 2024 is $939, but it was lower in previous years and may be higher in 2025. Your state will notify you of any change to your maximum benefit.

What if my income varies month to month because of seasonal work?

SNAP averages irregular income over the months you receive it. If you earn $3,000 in three months and nothing in the other nine, SNAP counts it as $1,000 per month across the year. Report all income honestly, and SNAP will calculate the average.

Can I get a larger benefit if I move to a state with a higher maximum?

No. The maximum benefit is set by the federal government and is the same in every state. However, some states have lower income limits or different deduction amounts, so your actual benefit may differ if you move.

If I get a tax refund, does that count as income for SNAP?

No. Tax refunds are not counted as income for SNAP purposes. However, if you receive the refund as a lump sum, it may count as a resource if your state has resource limits, which could affect your benefit in that month.

What happens if my household size changes?

The maximum benefit amount changes with household size. A family of four has a higher maximum than a family of three. If someone joins or leaves your household, report it when ready so your benefit is recalculated for the new household size.
