The average American household spends $475–$620 per month on groceries, according to BLS Consumer Expenditure data. But whether that's too much or too little depends entirely on your household size. A single person and a family of four are playing completely different games.
The USDA Official Food Plans
Since 1962, the USDA has published monthly cost-of-food reports showing what it costs to feed Americans at four spending levels: thrifty, low-cost, moderate-cost, and liberal. These numbers are based on actual food prices from grocery stores nationwide, updated regularly.
These are home-prepared meals only. Restaurant spending is not included. If you eat out regularly, your total food spending will be higher.
USDA Monthly Food Costs: Single Adults
For a single person eating all meals at home (2025 USDA estimates):
| Plan | Male 19–50 | Female 19–50 | What it means |
|---|---|---|---|
| Thrifty | $261/mo | $231/mo | Beans, rice, pasta, eggs. Minimal meat, no fancy produce. |
| Low-Cost | $337/mo | $297/mo | Balanced diet, some meat and fresh produce. |
| Moderate | $421/mo | $370/mo | Regular meat, variety of produce, some convenience items. |
| Liberal | $516/mo | $444/mo | Organic options, premium cuts, variety seafood. |

USDA Monthly Food Costs: Families
Family costs are not just individual costs multiplied. Buying in larger quantities is more efficient, so the per-person cost drops as household size grows.
| Household | Thrifty | Low-Cost | Moderate | Liberal |
|---|---|---|---|---|
| 2 adults (19–50) | $489/mo | $625/mo | $782/mo | $958/mo |
| 2 adults + 1 child (2–3 yrs) | $590/mo | $753/mo | $930/mo | $1,133/mo |
| 2 adults + 2 children (6–8, 9–11 yrs) | $759/mo | $966/mo | $1,187/mo | $1,448/mo |
| Family of 4 (reference family) | $817/mo | $1,040/mo | $1,275/mo | $1,555/mo |
| Family of 5+ | $1,020+/mo | $1,300+/mo | $1,590+/mo | $1,940+/mo |

What Plan Are You On?
Most middle-income American families fall somewhere between the low-cost and moderate plans. The thrifty plan is roughly what SNAP (food stamp) benefits cover. The liberal plan reflects how upper-income households typically eat.
If your grocery spending is significantly above the liberal plan for your household size, you're likely buying a lot of premium items, wasting food, or not tracking what you actually spend.
If you're below the thrifty plan, you may be eating a nutritionally limited diet or you're exceptionally skilled at couponing and bulk buying.
Per-Person Grocery Cost by Age
Kids are cheaper to feed than adults. Teenagers are almost as expensive as adults. Here's the USDA breakdown at the moderate spending level:
| Age Group | Male | Female |
|---|---|---|
| Under 1 year | $106/mo | $101/mo |
| 1–3 years | $152/mo | $147/mo |
| 4–5 years | $170/mo | $164/mo |
| 6–8 years | $207/mo | $196/mo |
| 9–11 years | $250/mo | $234/mo |
| 12–13 years | $304/mo | $265/mo |
| 14–18 years | $352/mo | $285/mo |
| 19–50 years | $421/mo | $370/mo |
| 51–70 years | $399/mo | $352/mo |

Why Most People Overspend on Groceries
Common Mistakes
- 1.Shopping without a list — impulse buys add 20-30%
- 2.Not tracking what you actually spent last month
- 3.Buying pre-cut, pre-packaged, or single-serve items (2-3x markup)
- 4.Food waste — the average household throws out $1,500/year
- 5.Mixing grocery and non-grocery items in one bill
What Actually Helps
- 1.Know your baseline — track receipts for 30 days first
- 2.Set a weekly limit, not monthly (easier to stick to)
- 3.Shop once per week, not multiple times
- 4.Buy store brands for staples (same quality, 30% less)
- 5.Scan receipts immediately so you see categories clearly
The Food Waste Problem
The USDA estimates Americans waste about 30-40% of the food supply. At the household level, that works out to roughly $1,300–$1,600 per year in food thrown away. That's $108–$133 per month going straight in the trash.
If you're spending above the USDA moderate benchmark for your household size, food waste is usually the first place to investigate. Most people dramatically underestimate how much they throw away.
Groceries vs. Dining Out: Where Does It Split?
The BLS Consumer Expenditure Survey breaks food into two categories: "food at home" (groceries) and "food away from home" (restaurants, takeout, delivery). The 2023 averages:
The grocery share ($507/month average) is close to the USDA moderate plan for a single adult but below the moderate plan for couples and families. That suggests many households either eat out heavily or are under-reporting grocery spending.
City vs. Rural: Regional Cost Differences
USDA food plans are national averages. Grocery costs vary significantly by location:
| Location Type | vs. National Average | Examples |
|---|---|---|
| Major coastal cities | +15–30% | NYC, SF, Boston, Seattle |
| Large inland cities | +5–15% | Chicago, Denver, Atlanta |
| Suburban areas | Near average | Most of the country |
| Midwest / South rural | -5–15% | Rural TX, KS, IA, AL |
| Hawaii / Alaska | +30–60% | Shipping and logistics costs |
If you live in San Francisco and you're spending at the USDA moderate plan for your household size, you're actually doing well. If you're in rural Iowa and spending at the liberal plan, something is off.
How to Know What You Actually Spend
Most people guess. And most people guess wrong, usually by 20-30%. Research consistently shows that people underestimate their grocery spending significantly when asked to recall it from memory.
The only way to know is to track it. Not estimate it, not remember it. Actually capture every grocery receipt for 30 days.
When you do, you'll typically find:
- Your grocery total is higher than you thought (often 20-30% higher)
- A significant chunk is non-food items bought at grocery stores (cleaning supplies, toiletries, pharmacy items)
- Some categories dominate unexpectedly (alcohol, snacks, or specific protein sources)
- Your per-trip average is consistent but your frequency is the variable
Once you have the real number, compare it to the USDA table for your household size. That's your actual baseline. Then you can decide where to cut.
Practical Ways to Spend Less
Track for 30 days first, then budget
You can't budget effectively without knowing your real baseline. Scan every grocery receipt for one month before setting a target.
Meal plan before shopping
Know what 5-7 dinners look like before you go to the store. This reduces waste and keeps you from buying things with no plan for using them.
Buy store brands for staples
Flour, rice, pasta, canned tomatoes, eggs, butter, milk — store brand vs. name brand quality difference is negligible. Price difference is 20-40%.
Reduce shopping trips
Every extra trip to the store adds impulse purchases. Studies show more trips = more spending. Once a week is the sweet spot for most households.
Freeze before food expires
Bread, meat, and many vegetables can be frozen before they go bad. The habit alone can save $50-100/month in waste for a family.
Bottom Line
The USDA moderate plan is a reasonable target for most households. If your grocery spending is above that for your household size, you're spending more than average, not necessarily too much. Your location, dietary needs, and preferences all affect what's right for you.
What matters is knowing your actual number first. Then comparing it to a benchmark. Then deciding where to adjust. You can't make that decision based on estimates.
