The headline number: $338 per person per month
According to the USDA's Cost of Food Reports (low-cost plan, updated 2026) and the Bureau of Labor Statistics' Consumer Expenditure Survey, the average American spends approximately $338 per person per month on food at home — what most people call "groceries." That works out to about $78 per week or $4,056 per year.
But that single number hides enormous variation. The same household structure can spend twice as much or half as much depending on age, region, and shopping habits. The averages below come from USDA published data and BLS Consumer Expenditure tables. Inflation-adjusted to 2026 dollars where source data is older.
By age group
Spending peaks in the 35–54 age range when household size and food consumption are both at their maximum.
- Children (1–3): ~$135/month
- Children (4–8): ~$165/month
- Teens (14–18): ~$245/month
- Adults (19–50): ~$345/month
- Adults (51–70): ~$315/month
- Adults (71+): ~$285/month
Why teenagers cost almost as much as adults: caloric needs peak in adolescence. A 16-year-old boy in a growth spurt eats more than most 30-year-old adults — a fact that surprises most parents budgeting for the first time.
By household size (per-person decreases with scale)
Larger households spend less per person because of bulk-buying efficiency and reduced waste. The economies of scale are real but smaller than people think.
- 1 person: $415/month per person
- 2 people: $360/month per person ($720 total)
- 3 people: $325/month per person ($975 total)
- 4 people: $295/month per person ($1,180 total)
- 5+ people: $265/month per person ($1,325+ total)
The single-person premium is roughly 40% compared to a family of 4 on a per-person basis. This is the single biggest reason solo households over-spend on groceries: the structural cost is genuinely higher, not a personal failure.
By household income
Higher-income households spend more in absolute dollars but less as a percentage of income. The bottom income quintile spends roughly 13% of post-tax income on food at home; the top quintile spends about 6%.
- Bottom 20% income (<$28k): $245/person/month, 13% of income
- Lower-middle (20–40%): $290/person/month, 10% of income
- Middle (40–60%): $335/person/month, 8% of income
- Upper-middle (60–80%): $380/person/month, 7% of income
- Top 20% (>$155k): $445/person/month, 6% of income
The top income quintile spends 80% more in dollars than the bottom — but the bottom spends more than twice as large a share of their income. This is what economists call Engel's Law: as income rises, the absolute amount spent on food rises but its share of total spending falls.
By US region
Cost-of-living differences mostly explain regional variance, with the Northeast and West paying premiums of roughly 8–15% over the South and Midwest.
- Northeast (NY, MA, NJ): ~$385/person/month
- West (CA, WA, OR): ~$370/person/month
- Midwest (IL, OH, MI): ~$320/person/month
- South (TX, FL, GA): ~$315/person/month
Within regions, urban-rural gaps are even larger. Manhattan grocery spending averages ~50% above the national mean; rural counties in the Plains states often run 20% below.
How your bill compares: a quick benchmark
Take your last full month of grocery spending. Divide by the number of people in your household. If the per-person number falls within ±15% of your demographic's average above, you are normal. If it is more than 25% above, there is room to optimize. If it is more than 25% below, either you are doing something exceptional, or you are forgetting categories (do you count alcohol? household paper? convenience store stops?).
The most reliable way to know is to track every receipt for one full month. Most people underestimate their actual grocery spend by 20–30% when asked to recall it without data.
The trend: where grocery prices are heading
Food-at-home prices in the US increased roughly 25% cumulatively from 2020 to 2025, according to BLS CPI data — far outpacing the official overall inflation rate over the same window. The 2026 rate of grocery inflation has moderated to ~2.8% year-over-year, but the cumulative price level remains elevated relative to pre-pandemic.
What this means practically: a household that was comfortably spending $700/month on groceries in 2019 is now structurally facing $875+/month for the same basket — even with no behavior change. If your grocery spend feels uncomfortable in 2026, this is a major reason. It is not just you.
Frequently asked questions
How much should I be spending on groceries per month?
For a single adult, the USDA's low-cost plan suggests ~$345/month and the moderate-cost plan suggests ~$430/month in 2026 dollars. For a family of 4 with two adults and two kids (ages 6 and 12), expect ~$1,150–$1,400/month on the moderate plan. Use these as benchmarks, not targets — your actual sustainable number depends on your income and other fixed costs.
Why is my grocery bill so much higher than the average?
The most common reasons: you live in a high-cost metro area (Northeast/West can run 15% above national average), you shop multiple times per week (impulse purchases add 15–20% per visit), you buy a lot of prepared meals or alcohol (often 25–35% of total when included), or you are estimating instead of measuring. Track every receipt for one month before making any judgment.
Are grocery prices still rising in 2026?
Yes, but slowly. The 2026 year-over-year food-at-home inflation is ~2.8% — much lower than the 11–13% peaks of 2022 but still positive. The cumulative price level from 2020 to 2026 is roughly 28% higher, which is the structural reason most households feel grocery pressure compared to pre-pandemic norms.
How does grocery spending compare to dining out?
BLS data shows the average US household spends about $5,750/year on groceries (food at home) and $3,650/year on restaurants/takeout (food away from home) — roughly a 60/40 split in 2026, down from 65/35 in 2019 as dining out has rebounded. High-income households tilt closer to 50/50.
Where can I find official grocery spending data?
The two authoritative sources are the USDA's Cost of Food Reports (updated monthly, broken down by age/sex/plan level) and the BLS Consumer Expenditure Survey (annual, broken down by demographics and region). Both are free, public, and the basis for all the numbers in this article.
