Add a ninth person to a Supplemental Nutrition Assistance Program household and, starting October 1, 2026, the math changes in a way most coverage of the annual SNAP increase skips entirely: the U.S. Department of Agriculture’s fiscal year 2027 update sets a flat $225 add-on to the maximum monthly allotment for every additional person from nine through 17. It is a separate number from the jump a family goes from four to five people sees, calculated on its own formula. Households this large are a small share of SNAP’s caseload, but the rule that governs their benefit is one of the least explained parts of the yearly reset. For a 12-person household, that single per-person number now determines nearly a fifth of the family’s total maximum monthly allotment, which is why a $7 change to it moves real money.
The Formula Hiding Past Household Size Eight
USDA does not publish a maximum SNAP allotment for every household size all the way up to 17. Instead, the fiscal year 2027 table lists specific dollar maximums for households of one through eight people, then switches to a flat per-person add-on for every person past eight, all the way through 17. A nine-person household’s maximum allotment equals the eight-person maximum plus one add-on; a fifteen-person household’s maximum equals the eight-person maximum plus seven add-ons. Above 17 people, USDA caps the calculation rather than continuing to add per-person amounts indefinitely.

From $218 to $225: What Actually Changed
The Food and Nutrition Administration’s fiscal year 2027 cost-of-living adjustment memo, dated August 21, 2026 and available on USDA’s official guidance portal, sets that per-person add-on at $225 for the 48 contiguous states and D.C. A year earlier, under the fiscal year 2026 figures still posted on the Food and Nutrition Administration’s cost-of-living adjustment page, the same add-on was $218. That $7 increase is smaller in dollar terms than the jump in almost every other SNAP figure this year, but it applies once for every person past the eighth, so a 12-person household’s total add-on moved from $872 to $900 in a single reset.
Who Actually Lives in a Nine-to-17-Person SNAP Household
A household this size in SNAP’s own definition is not necessarily one family in the traditional sense. The Food and Nutrition Administration’s SNAP eligibility page defines a household simply as everyone who lives together and purchases and prepares meals together, one unit for benefit purposes regardless of how many separate families that includes. Spouses and most children under 22 are folded into the same household even if they buy and cook separately. That definition is why multigenerational homes, kinship caregivers raising several related children, and large foster placements can all land in the nine-to-17 range, even though no single wage earner supports the whole group. Foster children under 18 who are placed with a household member and treated as part of the same food-purchasing unit are counted the same way, which is one more path by which an ordinary-looking home ends up filing as a household of ten or more.
Why the Add-On Is Smaller Than It Looks
USDA’s own maximum-allotment table shows why the per-person add-on is not a generous number. Under the fiscal year 2026 chart, the maximum allotment climbed from $1,571 for a seven-person household to $1,789 for an eight-person household, a $218 jump, exactly the same as the flat add-on that then applies to every person after that. Smaller households see less consistency: the difference between a one- and two-person maximum was $248, but between a four- and five-person maximum it was only $189. Once a household passes eight people, in other words, USDA stops publishing a size-specific number and instead applies one flat rate, now $225, no matter whether the household has nine members or sixteen. That flattening is intentional: USDA’s allotment formula is designed to reflect economies of scale, on the theory that very large households share fixed costs like cooking fuel and bulk grocery purchases more efficiently than small ones, so each additional person needs proportionally less, not more.
The Memo Behind the $225
The $225 figure, like every other number in the fiscal year 2027 update, comes from the Food and Nutrition Administration’s cost-of-living adjustment memorandum, issued August 21, 2026 and posted on USDA’s own guidance document alongside the department’s other current SNAP policy memos. It replaces the $218 add-on states have been using since October 2025, and it takes effect the same day as the rest of the annual reset, October 1, 2026, without any household needing to file paperwork to receive it. A caseworker verifying a large household’s benefit this fall will be checking it against the same document. That document, not any third-party estimate, is the one number that will actually appear on a state’s benefit calculation worksheet this October.
