For two adults and two school-age kids, a grocery budget of roughly $1,000 to $1,700 a month covers the range of the USDA's 2026 food plans, depending on how tightly you shop. The USDA's September 2026 food plans put a family of two adults and two school-age kids at $1,024 a month on its lowest-cost plan and about $1,389 on its moderate plan.
Those are useful benchmarks, but the number that matters is yours. Below is what the USDA plans say, how to adjust them for your kids' ages, and how to set a grocery budget from what you actually spend.
How much should a family of 4 spend on groceries?
The USDA publishes four food plans every month, from Thrifty (lowest cost) to Liberal (highest). Each one prices a nutritious diet at a different cost level. Here's the September 2026 report for a family with a man and a woman of working age (about 20 to 50), one child aged 6 to 8 and one aged 9 to 11:
| USDA plan (Sept 2026) | Weekly | Monthly |
|---|---|---|
| Thrifty | $236.30 | $1,024.00 |
| Low-Cost | $260.10 | $1,126.90 |
| Moderate-Cost | $320.50 | $1,389.20 |
| Liberal | $388.00 | $1,681.80 |
The Thrifty figure is the USDA's own family-of-four total. The other three plans are listed per person, so we added up the four people's costs ourselves.
A few things to know before you compare your own bill:
- The plans assume you cook everything. The USDA says the plans are based on all meals and snacks being prepared at home. Takeout, school lunches and coffee runs are extra.
- They're national averages. The prices are U.S. averages, so your area may cost more or less.
- They move with prices. The USDA updates the costs monthly using the Consumer Price Index.
For context, the Thrifty plan's family of four is the same one the USDA uses to set the maximum SNAP benefit.
Does it change with your kids' ages?
Yes, quite a lot. Food costs generally rise as kids get older. Using the same Moderate-Cost plan:
- Two little kids (ages 2–3 and 4–5): about $1,163.50 a month.
- Two school-age kids (6–8 and 9–11): about $1,389.20 a month.
- Two teenagers (a boy and a girl): about $1,461.60 a month.
To build your own number, the USDA's method is simple: add up the cost for each person in your household, then adjust for household size. The costs assume a four-person household, so for a family of four there's no adjustment. A family of three adds 5%, and a family of five or six subtracts 5%.
Why does my grocery bill feel higher than this?
Partly because food prices kept rising. The USDA's Economic Research Service says grocery prices in September 2026 were 1.8% higher than a year earlier, and it forecasts food-at-home prices to rise 2.3% for 2026 overall.
The Bureau of Labor Statistics found that the average household spent $6,491 on food at home in 2025, compared with $6,224 the year before. That's an average across households of every size, about $541 a month. Spending on meats, poultry, fish and eggs alone rose 11.7%.
The other reason is that a grocery receipt is rarely just food. Paper towels, shampoo, pet food and the birthday card at the checkout all land on the same receipt, while the USDA plans only count food. If your bill is well above the plans, split out the non-food items before you decide you're overspending.
How to set your family's grocery budget
Start from what you really spend, then pick a target.
- Measure the last three months. Add up every grocery trip, including the quick stops. Receipts, card statements and order history all work. Here's a made-up example: three months totalling $3,600 means you spend about $1,200 a month.
- Compare it to the plans. $1,200 sits between the Low-Cost and Moderate-Cost plans for a family with school-age kids. That's a normal place to be.
- Pick a monthly number. If money is tight, aim a little lower than what you spend now. If you're already near the Thrifty plan, holding steady is a win.
- Turn it into a weekly number. The USDA turns weekly costs into monthly ones by multiplying by 4.333. Go the other way: $1,200 ÷ 4.333 is about $277 a week. A weekly number is easier to keep in your head at the store.
If groceries keep getting mixed up with household supplies, give them separate categories. Our guide to household budget categories has a starting list.
How can a family of 4 spend less on groceries?
The University of Tennessee Extension's grocery tips cover the basics:
- Plan the week's meals before you shop.
- Check the fridge, pantry and freezer first, and use up food that's about to spoil.
- Stick to your list once you're in the store.
- Compare canned, frozen and fresh versions of the same food.
- Try store brands, which UT Extension says are often cheaper and just as good.
- Read the unit price. Their example: a 1-pound bag of carrots at $0.89 is $0.89 a pound, while a 5-pound bag at $3.54 is $0.71 a pound.
How do you stick to it mid-month?
The budget only works if you check it before you're out of money. A simple test: halfway through the month, you should have spent about half.
Say your budget is $1,200 and it's day 15 of a 30-day month. If you've spent $744, that's 62% of the budget with 50% of the month gone. You still have $456, but you're ahead of an even pace. Knowing that on day 15 gives you two weeks to plan cheaper meals instead of a surprise at the end.
That means logging every trip, including the $9 milk run. If that's the habit that slips, see how to stick to a budget.
How to do this in SimplifyPocket
SimplifyPocket doesn't connect to your bank. You add each grocery trip yourself, which is how you notice the pace while you can still change it.
- Start with your old receipts. Use Scan or upload to pick several receipt photos at once. Each one becomes a draft you check before saving, so your three-month number is quick to build. More on that in how to organize receipts.
- Give Groceries a budget. Budgets run for each cycle, either the calendar month or custom start and end days (for example, payday to payday). The app shows how much is left as you go.
- Log trips as they happen. Scan the receipt at the checkout, or tap the mic and say something like "86 dollars groceries," then check it and save.
- Watch the pace badge. Once your income is in, a badge on the dashboard shows whether your spending this cycle is on track, spending fast, or over your income.
