How Much Should You Spend on Groceries? (And What To Do If You're Over)

What the average household actually spends

The USDA publishes something called the Thrifty Food Plan. It's the cheapest of four official food plans (Thrifty, Low-Cost, Moderate-Cost, Liberal), built around the assumption that you're cooking most meals at home, buying store brands, and not wasting a lot. It's the same plan SNAP benefits are calculated from, which gives you a sense of how careful it assumes you're being.

For 2026, the US numbers look like this. A single adult lands at roughly $315 a month, or about $73 a week. Two adults run about $580 a month. A family of four (two adults and two school-age kids) sits at around $950 a month, or $219 a week. Those are the baseline figures the federal government considers nutritionally adequate for a household shopping with intention. (Source: USDA Food and Nutrition Service, Official Food Plans.)

Outside the US, the equivalent benchmarks live elsewhere. Canada uses figures from Statistics Canada's household food expenditure surveys. Australia uses data published by the Australian Bureau of Statistics. The methodology differs a bit, but the idea is the same: an official, defensible number for what a careful shopper can spend without compromising on basic nutrition.

If you're well above the Thrifty Plan for your household size, that's not automatically a problem. Plenty of people are. But it's the cleanest answer to "how much should I spend on groceries" that doesn't come with seventeen caveats. You can also try the grocery budget calculator for a personalised target based on your household size.

Why you're probably over, and it's not what you think

Here's the part that surprised me. I always assumed if I was over budget, the damage came from the big weekly shop. The cart full of stuff. The receipt that makes you wince when it prints.

It wasn't. The big shop was almost always fine.

The damage was always the in-between trips. The midweek "I just need bread and milk" run that turned into $47. The Saturday morning bagel stop where I also picked up "a few things." The work-from-home dash for one specific sauce I needed for dinner. Three or four of those a week and I'd quietly lit $150 on fire, because none of them felt like a real grocery trip.

Most people don't count those trips in their grocery spending. They feel like errands. But it's the same money coming out of the same account, and across a month it adds up faster than the weekly shop ever does.

The other thing nobody warns you about is brand drift. You start buying the name-brand version of one thing because it was on sale, then you just keep buying it. A year later half your cart is the expensive version of stuff you bought for half the price last year. Nothing about your life changed. The cart just got a few cents more expensive at a time.

The only way to know for sure

You can guess at this stuff, but guessing doesn't help.

The problem with using your bank statement is that it tells you almost nothing. "WALMART - $187" is not useful information. You don't know if that $187 was a week of groceries or two days. You don't know how much of it was actual food versus paper towels and dog treats. You don't know which categories you overspent on. You just know a number left your account.

To actually fix the problem, you need to see it at the item level. Not "I spent $187 at Walmart" but "I spent $34 on snacks, $22 on beverages, $61 on produce." That's a different conversation. That one's actionable.

I ended up using Groceries Tracker for this. I scan the receipt after each trip and it pulls out every line item, categorises it, and stacks it against the previous month so I can see the patterns without doing math. It isn't magic, it's just doing the boring data entry I would never actually do myself, which is the whole reason I stuck with it where I'd quit on the spreadsheet I started in 2022.

What to do if you're over the benchmark

Once you have your real numbers, ignore the total for a minute and look at categories. The total is too abstract to act on. Categories tell you where the leak is.

Sort categories from highest to lowest. The first one is where you start. There's almost always one category that's way out of proportion. For me it was snacks. I would have sworn it was meat and produce, and it was snacks by a wide margin. For a friend of mine it was beverages. For my parents it's bakery items, which they insist are a household necessity. Whatever the top line is, that's the lever.

Next, look at items you buy on repeat. The same five or six things show up on most of your receipts. Compare what you paid for those across stores. You might find that the chicken thighs you buy every week are $4 cheaper at the store you don't usually go to. Repeated items are where small price differences compound the hardest, because you're paying the difference every week, not once.

Finally, count your trips. Not how many "big shops" you did. Count every time food entered the house from a store. If it's more than five or six in a month, those extra trips are almost certainly costing you more than you think. Going from eight trips a month to five is one of the easiest wins in this whole exercise, because it doesn't require you to eat differently. It just requires you to plan slightly better.

The advice you usually see is "cut back on snacks" or "buy store brand." Sometimes that's the right call. But you can't tell which advice applies to you without looking at your own data first. Generic tips are why most grocery budgets fail.

Turning the gap into something

Here's the part that made the tracking actually feel worth it. If you spend less than the benchmark for your household size in a given month, that gap is real money. Not theoretical. Not the kind of "savings" the receipt brags about at the bottom for things you weren't going to buy anyway. Actual money that didn't leave your account.

You can put that money toward something specific. A trip. A new mattress. A buffer for the holidays. Whatever you want. The point is to attach the gap to a real thing, because once it has a name, it stops getting quietly absorbed back into next month's spending.

Groceries Tracker has a Savings Goals feature that does this automatically. You set a goal, and each month it adds whatever you came in under the benchmark toward that goal. It's a small thing, but it changes the way you think about the whole exercise. You stop trying to "save money on groceries" in the abstract and start funding something real.

Bottom Line

The honest answer to "how much should you spend on groceries" is: probably less than you're spending now, but the right number isn't a universal figure. It's whatever you can hit consistently without making your life worse. The USDA Thrifty Plan is a useful floor; your real target sits somewhere between that and what you're spending today.

If you've never seen your spending broken down at the item level, that's the first thing worth doing. You can try Groceries Tracker free and have a clear picture of where your money's going by the end of the week.
