QUICK ANSWER
For one adult age 20 to 50, the USDA benchmark is $440.67–$549.08 a month on the moderate-to-liberal plans, using the midpoint of female and male rates; two adults $807.89–$1006.64; a family of four about $1388.73 on the moderate plan. These are model estimates, not actual average spending. The thrifty plan is lower for every household shown.
USDA monthly grocery budget by household.
Monthly figures apply the USDA’s household-size adjustments to its August 2026 per-person weekly costs. Adults use the midpoint of the female and male 20–50 rows; the family of four uses the USDA’s reference household composition. Summed rounded rates can differ slightly from the published reference total. These are modeled plan costs, not observed averages.
| Household | Thrifty | Low-cost | Moderate | Liberal |
|---|---|---|---|---|
| 1 adult | $343.43 | $355.65 | $440.67 | $549.08 |
| 2 adults | $629.63 | $652.03 | $807.89 | $1006.64 |
| 2 adults + 1 child (4–5) | $798.92 | $810.29 | $1003.65 | $1242.05 |
| Family of 4 (2 adults, kids 6–8 & 9–11) | $1023.45 | $1125.71 | $1388.73 | $1678.60 |
| 2 adults + 2 teens (14–19) | $1158.64 | $1185.51 | $1461.09 | $1788.23 |
Age changes the estimate. For example, a male 14–19 costs $93.10/week against $70.30 for a child 6–8 on the moderate plan.
What each plan actually buys.
Thrifty.
the USDA’s lowest-cost nutritious plan; SNAP allotments are based on it. Mostly ingredients, very few convenience items, tight use of everything.
Low-cost.
home cooking with a little more variety and convenience.
Moderate.
the middle cost level among the USDA food plans.
Liberal.
the top of the USDA range; more convenience and premium choices.
None of these include restaurants, takeout, coffee runs or delivery. They are modeled food-at-home costs; compare them with your own grocery receipts to choose a useful target.

Common questions.
How much should one person spend on groceries per month?
On the USDA’s August 2026 benchmarks, one adult age 20–50 living alone is estimated at $343.43 a month on the thrifty plan, $355.65 low-cost, $440.67 moderate and $549.08 liberal (an average of the male and female figures, with the single-person adjustment). These are modeled food-at-home costs, not observed spending.
Is $300 a month enough for groceries?
For one adult age 20–50 living alone, $300 is just below the USDA thrifty estimate for a woman and further below it for a man. Some households spend less; this is a benchmark, not a minimum. For two adults, $300 is well below the thrifty estimate.
Is $200 a week enough for groceries?
That is $866.60 a month — enough for two adults on the moderate plan ($807.89) with room to spare, and below the thrifty plan for a family of four ($1023.45).
Is $400 a month enough for groceries?
For one adult age 20–50, $400 is near the moderate estimate for a woman and between low-cost and moderate for a man. For two adults it is below the USDA thrifty estimate for the reference ages. Your actual spending can differ.
What is the 5-4-3-2-1 grocery shopping rule?
A list method, not a budget rule: buy 5 vegetables, 4 fruits, 3 proteins, 2 grains and 1 treat (versions vary). It is a simple way to stop a shop drifting toward snacks — our aisle-ordered list does the same job with your actual meals.
Why does my shop cost more than the USDA benchmark?
City, store, brands, dietary needs and the amount you eat at home can all change your bill. These plans are modeled costs, not observed averages. Compare your own basket with the benchmark.
