How USDA builds this number
USDA prices food person by person, by age and sex, then adjusts for household size, because a family of four is USDA's baseline household size. This is the USDA reference family of four, the same family the SNAP maximums are built from. Here is the build-up for this family, monthly cost per person at each plan:
| Person | Thrifty | Low-Cost | Moderate | Liberal |
|---|---|---|---|---|
| Male, 20 to 50 years | $318.90 | $317.20 | $398.10 | $486.20 |
| Female, 20 to 50 years | $253.70 | $275.70 | $336.10 | $428.80 |
| Child, 6 to 8 years | $209.20 | $262.00 | $304.50 | $356.30 |
| Child, 9 to 11 years | $241.90 | $270.90 | $349.50 | $407.40 |
| Added together | $1,023.70 | $1,125.80 | $1,388.20 | $1,678.70 |
| After the size adjustment (no adjustment) | $1,023.70 | $1,125.80 | $1,388.20 | $1,678.70 |
The size adjustment for a household of 4 is: no adjustment. Different ages in your family? The full person-by-person table is on the grocery costs index, and the same method works for any mix.
What this means for your budget
The gap between the thrifty floor ($1,024) and the moderate plan ($1,388) is $4,374 a year. That gap is not failure or success; it is the price of variety, convenience, and brands. Families who cook most meals from scratch and waste little can live near the thrifty line. Families with teenagers, sports schedules, and a standing pizza night will land near moderate, and that is normal, not overspending.

Frequently asked questions
How much does the USDA say a family of 4 should spend on groceries?
For two adults plus two children, 6 to 8 and 9 to 11 years old, the USDA food plans for August 2026 run from $1,024 a month on the thrifty plan to $1,679 a month on the liberal plan. The moderate-cost plan, where most middle-income families land, is $1,388 a month, about $321 a week.
What is the thrifty food plan?
It is the USDA's bare-bones nutritious minimum: the cheapest way to feed a family a healthy diet, assuming nearly everything is cooked from scratch at home and almost nothing is wasted. It is also the plan SNAP maximum benefits are built from.
Why might my family of 4 spend more or less than this?
These figures assume two adults plus two children, 6 to 8 and 9 to 11 years old. Ages matter a lot: in this family the most expensive person to feed on the thrifty plan is the male, 20 to 50 years, at $319 a month. Swap a toddler for a teenager and the total jumps. Prices where you live matter too; these are national averages.
