How much should you spend on groceries? Start with what's really food

A family of four eating every meal at home on the USDA's moderate-cost food plan needed $1,389.20 a month in September 2026, according to the USDA's official food plan cost report issued in October. The thrifty plan, the cheapest of the four, came to $1,024.00 for the same family. Food-at-home prices rose 1.8% in the 12 months to September, according to the Bureau of Labor Statistics, slower than overall inflation.

Those are benchmarks for food. Your grocery line probably isn't. A weekly supermarket run usually includes paper towels, shampoo, cold medicine, and the cat's food, and a budget that files all of it under groceries makes food look more expensive than it is and hides the rest. This guide shows how to find your real food number, how to compare it with the USDA plans, and how to set a budget you can keep. Household examples are fictional.

How much should you spend on groceries a month?

The USDA publishes the monthly cost of four food plans: thrifty, low-cost, moderate-cost, and liberal. Each one is a nutritious diet with every meal and snack made at home, priced at a different level. They are a useful range for comparison, not a target anyone sets for you.

To build the figure for your own household, add the monthly cost for each person by age and sex from the USDA tables, then adjust for household size: add 20% for one person, add 10% for two, add 5% for three, and subtract 5% for five or six people. The table above applies those adjustments. The thrifty plan is calculated from a newer food basket, so it is not always cheaper than the low-cost plan for every person, but for the family of four it is $1,024.00.

If your real food spending sits inside this range, your grocery budget is probably fine. If it sits well above the liberal plan, the next section is the first place to look.

Why does your grocery spending look higher than it is?

Because the receipt is not all food. Supermarkets and warehouse stores sell a large share of a household's non-food basics, and they all land on one card charge. Common items that end up in the grocery line:

• Household: cleaning supplies, paper towels, trash bags, laundry detergent, light bulbs.
• Personal care: shampoo, toothpaste, razors, diapers.
• Pharmacy: cold medicine, vitamins, prescriptions picked up at the store counter.
• Pets: food, litter, treats.
• Other: alcohol, gift cards, a birthday card, a phone charger.

Take a fictional family of four whose grocery category shows $1,420 for October. That is between the USDA moderate and liberal plans, and it feels like a food problem. After going through the month's receipts, $140 was household supplies, $95 personal care, $45 pharmacy, and $60 pet food. That is $340 of non-food spending, 24% of the total.

Their real food spending was $1,080, a little under the low-cost plan. The grocery budget did not need cutting. The household, personal care, and pet lines needed budgets of their own, because until now they had none.

How do you split a grocery receipt in your budget?

Record the store charge once, then divide it across categories so each part counts where it belongs. Your bank still shows one charge, and your budget shows food, household, and the rest separately.

1. Group the receipt lines by category. You do not need every item, only the subtotal for each category.
2. Deal with sales tax. Many US states tax groceries at a lower rate than other goods, or not at all, so most of the tax line usually belongs with the non-food items. If that is too fiddly, add the tax to the largest line.
3. Check that the parts add up to the amount charged to your card, including any discounts or bag fees.
4. Save the split and move on. A split that takes longer than a minute will not survive a busy month.

In Nethaven you can split a transaction across categories on the web, iPhone, and Android. Tap Split under Category, add a line for each category, and save when the lines add up to the full amount. Each line counts in its own budget category, so opening Groceries shows a $150 receipt as $90 of $150, while the account keeps a single $150 transaction that matches your statement. A split can have 2 to 50 lines, and you can undo it at any time.

You do not need to split every receipt. A good rule is to split when the non-food part is big enough to change a decision, for example more than $10 or about a tenth of the receipt. A pack of gum can stay in groceries. The same split works for hobby supplies bought with the weekly shop, as budgeting for hobbies shows.

How do you set a grocery budget from your own numbers?

Use your own spending as the starting point and the USDA plans as a check. Here is a method that works with three months of receipts or transactions:

1. Find the real food total for each month. Split the large receipts as above. For the small ones, a rough estimate is fine.
2. Average the three months. Leave out a month with a big one-off, such as a holiday meal, and plan for that separately.
3. Compare the average with the USDA plan for your household. Below low-cost or above liberal is worth a closer look, not an alarm.
4. Adjust for prices. Food-at-home prices rose 1.8% in the year to September 2026. On a $1,080 food average, that is about $19 a month.
5. Set the budget and a separate line for each non-food category you found in the receipts.

The family in the example would set groceries at $1,100, household at $140, personal care at $95, pharmacy at $45, and pets at $60. The total, $1,440, is close to the $1,420 they spend now, with the extra $20 covering higher food prices. The difference is that each number is now one they can manage. If you are building the rest of the budget too, the budget calculator shows how these lines fit with income and fixed bills.

What if your real food spending is still too high?

Then you know the problem is food, and you can work on it directly. A few changes tend to make the biggest difference:

• Plan meals around what you already have. Check the fridge and cupboards before writing the list.
• Count food that goes off. Food thrown away is the most expensive food you buy.
• Separate takeout and delivery. Prepared meals belong in dining out, not groceries. Mixing them hides both.
• Watch the warehouse-store trip. Bulk buys save money per unit only when you finish them.

If your prices have risen more than the national figure, your own basket may simply be different. Why your budget rises faster than inflation shows how to separate higher prices from buying more.

How do you keep your grocery budget on track during the month?

Check it once a week, not only at the end of the month. A grocery budget of $1,100 is about $254 a week, using the USDA's 4.333 weeks per month. If the first two weeks used $650, you know on day 14 that the rest of the month has $450, not on day 31.

Record receipts the same day, or scan them, so the number stays current. Nethaven shows spending against each category as transactions are added, imported, or scanned from a receipt photo. It does not connect to stores or read loyalty-card data, so the split happens when you review the transaction.
