About this calculator
SNAP benefits are calculated by taking a maximum monthly allotment for your household size (published annually by USDA), then subtracting 30% of your household's net income — the idea being SNAP fills the gap between what a household can reasonably spend on food and the full cost of a minimally adequate diet. Net income itself comes from gross income minus a standard deduction, an earned income deduction (20% of earnings), dependent care costs, medical expenses for elderly/disabled members over $35/month, and excess shelter costs above half of income (capped for most households, uncapped for elderly/disabled). This calculator simplifies that chain into the core net-income-and-30%-subtraction formula so you can estimate roughly where you'd land. Actual SNAP determinations run through your state agency with exact current-year deduction figures and gross/net income tests, so treat this as a planning estimate, not an approval prediction.

FAQ
Why is my estimate different from what my state says?
States apply current fiscal-year figures for maximum allotments, standard deductions, and shelter caps that update every October, and some states have slightly different rules for utility allowances and vehicle/asset tests. This tool uses representative recent figures for estimation; your state SNAP office has the authoritative numbers for your case.
Is there an asset limit for SNAP?
Most states have eliminated a strict asset test for regular SNAP applicants through broad-based categorical eligibility, but some states still apply limits (commonly around $2,750, higher for households with an elderly or disabled member). Check your specific state's rules since this varies more than income rules do.
Does earned income get treated differently than unearned income?
Yes, 20% of earned income (wages, self-employment) is deducted before the net income calculation, while unearned income (Social Security, unemployment, child support received) is counted in full. This deduction is meant to offset work-related costs and encourage participation in the workforce.
What's the elderly/disabled shelter deduction difference?
Households with an elderly (60+) or disabled member get an uncapped excess shelter deduction, meaning very high housing costs can fully offset countable income, while other households face a shelter deduction cap that limits how much high rent can reduce net income for benefit purposes.
Accuracy and limitations
- Results are estimates before tax, fees, and inflation unless an input explicitly covers them.
- Rates are treated as fixed for the whole period — variable-rate products will drift from this projection.
- This is educational maths, not financial advice. Check anything contractual with the lender or your accountant.
