Not every extra person added to a food stamp case is worth the same amount on paper. This year’s FY2027 update from USDA, dated August 21, 2026, quietly contains an oddity buried in its household-size table: of the eight per-person increases listed, the smallest one by a wide margin is the jump from a six-person household to a seven-person household.
Where $153 Sits Among the Eight Steps
Under the FY2027 table, a six-person household in the 48 states and D.C. has a maximum monthly allotment of $1,463. A seven-person household’s maximum is $1,616. The difference, $153, is the smallest gap anywhere in the household-size table before the flat per-person add-on kicks in at size nine.
That is not a fluke unique to this year’s numbers. USDA’s SNAP eligibility page shows the same six-to-seven step was the smallest in the FY2026 table too: $1,571 for seven people minus $1,421 for six people comes to $150, again the narrowest jump on the page. The formula behind the FY2027 Cost-of-Living Adjustments memo carried that same dip forward, just at slightly higher dollar amounts.
Once a household passes eight people, the table stops listing individual sizes altogether and switches to a flat per-person add-on instead, the same mechanism that eventually produces the flat ceiling for households of 18 or more. The six-to-seven step is the last place in the table where household size still moves the number in an uneven, size-specific way before that flatter formula takes over.

The Bigger Jumps On Either Side of It
Look at the steps that surround it and the dip stands out further. In FY2026, going from a five-person household to a six-person household added $238 to the maximum allotment. Going from a seven-person household to an eight-person household added $218. Both of those neighboring steps dwarf the roughly $150 gap sitting between them. A household that grows from six to seven gains less new benefit than a household growing from five to six, or from seven to eight, even though every step represents exactly one more person to feed.
The unevenness runs through the whole table, not just this one spot. Going from one person to two added $248 in FY2026; from two to three, $239; from three to four, $209. None of those steps match each other cleanly, and the six-to-seven step is simply the smallest of the bunch, in both the year that is ending and the year about to start.
Why the Step Sizes Aren’t Even
USDA’s cost-of-living guidance attributes the unevenness to a built-in economies-of-scale curve, not to any single step being miscalculated. A household’s per-person share of its maximum allotment declines gradually as household size rises above four, and because that decline is not a straight line, some size-to-size jumps absorb more of the annual cost increase than others. The six-to-seven jump simply lands at a point on that curve where the decline in per-person share happens to be steepest.
USDA does not publish a separate explanation for why the six-to-seven step specifically comes out smallest rather than the five-to-six or seven-to-eight step, but the pattern has now shown up in back-to-back fiscal years using two different sets of underlying Thrifty Food Plan costs, which suggests it is a structural feature of the formula rather than a coincidence of this year’s inflation numbers.
That is consistent with how USDA builds the Thrifty Food Plan in the first place. The plan is not one flat per-person cost multiplied by household size; USDA’s cost-of-living guidance describes it as a market-basket estimate recalculated each June for the cost of feeding a household, then adjusted by household size using the economies-of-scale curve described above rather than simple multiplication. A step from one size to the next is a fresh calculation against that curve each time, not a repeat of the same per-person number, which is exactly why some steps land larger than others without any single step being “wrong.”
What This Means for a Family Growing to Seven
A family that adds a seventh member is not actually guaranteed $153 more in its monthly deposit. The maximum allotment is only the ceiling; USDA’s program overview and eligibility materials describe how an actual benefit is calculated by taking 30 percent of the household’s net monthly income and subtracting that amount from the maximum for its size. Two households of seven with different incomes can land on very different real benefits, both capped by the same $1,616 ceiling.
What does move automatically for that seventh person is the household’s room under the income limits used to decide whether it qualifies at all, a separate part of the same FY2027 memo. The size of a household changes two different numbers in USDA’s system at once, and the maximum allotment table is only one of them.
For a family weighing whether to report a new seventh member right away, that distinction is the practical takeaway. The $153 figure describes the ceiling on what a seven-person household could receive at most; the income-limit change that comes with adding that same person, tracked on a separate table in the same FY2027 memo, is what usually determines whether the household’s actual monthly benefit moves at all.
