How to Save Money on Groceries: 12 Ways to Cut Your Bill

The short answer to how to save money on groceries comes down to three habits: shop from a plan and a list, compare the unit price instead of the sticker price, and stop throwing food away. Get those three right and your grocery bill falls without eating less or giving up quality.

But the first step isn’t cutting — it’s measuring. A grocery budget set without knowing what you actually spent over the last two or three months is just a guess. Below you’ll find how to set a realistic grocery budget, 12 practical ways to cut your grocery bill, a sample calculation, and the mistakes that quietly undo frugal grocery shopping.

How to set a grocery budget: measure 2–3 months first

Most households can name a number they think they spend on food, and the real total is usually different: corner-store top-ups, bakery runs and the “just a few things” on the way home rarely make it into the estimate.

1. Define what counts. Decide whether cleaning supplies, toiletries and pet food sit inside your grocery budget or in separate categories. The choice matters less than using the same definition every month.
2. Record every grocery purchase for 2–3 months. Small top-up trips included — card, cash and online orders alike.
3. Take the average. Flag unusual months: holidays, hosting guests, a big stock-up.
4. Set your target slightly below the average. Five to ten percent lower is realistic for month one. Trying to halve it overnight usually falls apart by week two.
5. Break it into weeks. A weekly limit is easier to steer than a monthly one.

Here’s an example grocery budget for a family of 4. The figures are purely illustrative, not a benchmark — what a family of four spends varies widely by location, diet and store.

If prices are rising quickly, update the target each month with a rolling three-month average instead of fixing one number; our guide to budgeting during inflation covers this in detail. Prefer cash? Put each week’s grocery money in its own envelope — see the envelope method.

How to save money on groceries before you shop

1. Plan a weekly menu

Meal planning to save money works because most of the savings happen at the kitchen table, not in the store. Spend 15 minutes at the start of the week sketching out dinners: what you’ll cook on which day, what becomes tomorrow’s lunch, and which night is “use up what’s in the fridge” night. With a plan, one ingredient does double duty (a pack of ground beef becomes both tacos and pasta sauce) and the “what’s for dinner?” panic that ends in takeout happens less often.

2. Write a list — and follow the “not on the list, not in the cart” rule

Turn the menu into a list after checking the pantry, fridge and freezer. A monthly list works for staples like rice, oil and cleaning products; a weekly one covers fresh food. In the store the rule is simple: if it isn’t on the list, it doesn’t go in the cart. If you genuinely forgot something, add it — but “it was on sale” and “the kids asked” stay off. If total rigidity doesn’t suit you, allow a small buffer, say $10 a week for unplanned items.

3. Never shop hungry

Shopping on an empty stomach makes it far easier to add snacks, ready meals and sweets. Plan the trip for after a meal, or eat something before you go in. Rushed shopping at peak hours has a similar effect.

In the aisle: unit prices, store brands and seasonal food

4. Read the unit price

The price on the package doesn’t tell you how cheap a product is. Most shelf labels also show a unit price in smaller print — per ounce, per pound, per 100 g or per litre. Always compare using that number.

For example, a 16 oz box at $3.20 works out to $0.20 per ounce, while a 24 oz box at $4.32 costs $0.18 per ounce. The bigger box wins here, but not always: sometimes the “family size” has a higher unit price than the regular pack, especially when the smaller one is on sale. No unit price on the label? Divide the price by the weight.

5. Try the store brand

For staples like flour, sugar, rice, pasta, beans, canned goods and cleaning products, store brands (own-brand in the UK) are usually cheaper than the big names. Try the store version of five or six basics for a month and keep the ones your family likes.

6. Buy what’s in season

Fruit and vegetables in season tend to taste better and cost less. Build the menu around the season — root vegetables, cabbage and squash in winter, salads and berries in summer. Frozen produce is a sensible stand-in out of season.

In the cart: bulk buys, promotions and delivery fees

7. When does buying in bulk make sense?

Bulk buying only saves money when three conditions hold together: you use the item regularly, it keeps without spoiling, and its unit price really is lower. Laundry detergent, toilet paper, dried beans, pasta and canned goods fit. Fresh produce, a brand you’ve never tried or a stockpile you have no room for don’t. A bulk run inflates that month’s spending, so check that the following months come in lower.

8. Watch out for promotion traps

“Buy one, get one free”, “3 for 2” and “spend $50, get a gift” deals are real savings on things you were going to buy anyway. On anything else, they’re extra spending. Ask two questions: “Would I buy this without the deal?” and “Will we finish all of it before it expires?” If you can’t say yes to both, leave it on the shelf.

9. Count the delivery fee when ordering online

Online grocery orders can make frugal grocery shopping easier, since you’re not wandering the aisles. But delivery fees, service fees, minimum basket sizes and “add $12 more for free delivery” nudges add up. Combine orders into one a week, check your substitution settings, and when comparing prices, add the fees to the basket total.

At home and at the checkout: waste, the freezer and your receipt

10. Manage expiry dates and food waste

Every item that ends up in the bin is money paid and never eaten. Use “first in, first out” in the fridge: new purchases go to the back, older ones to the front. Learn the labels, too: a “use by” date is about safety, while “best before” or “best if used by” is about quality, and food is often fine after it. One “eat what’s left” dinner a week is the easiest way to cut waste.

11. Use your freezer strategically

The freezer solves bulk buying and waste at the same time. Slice bread and freeze it, taking out only what you need. Split meat and chicken into single-meal portions. Rescue leftovers, overripe bananas and unused herbs by freezing them. Label bags with the contents and date.

12. Check your receipt before you leave

The shelf price and the price that rings up aren’t always the same: a promotion might not be loaded, or an item may have scanned twice. Take 30 seconds to check before leaving and ask for a correction if something is off. Then log it in your budget before the receipt disappears.

Sample calculation: how much can you cut your grocery bill?

Here’s what could happen for the example family above, spending $1,050 a month, if they adopted some of these habits. The numbers are hypothetical; yours depend on your basket and where you shop.

Treat this as a thinking tool, not a promise; only your own records will show which habits make a difference for you.

Common grocery budget mistakes

• Setting a target without measuring: A budget set without your real average is either too loose or breaks in week one.
• Counting only the big shop: Bakery runs, corner-store top-ups and market stalls can be a sizeable share of the total.
• Buying cheap food that spoils: A discounted item you throw away costs more than a full-price one you eat.
• Changing everything at once: Start with two or three of the 12 ideas and add more once they stick.
• Ignoring takeout: If groceries go down while delivery orders go up, total food spending hasn’t changed. Watch both.

A 60-second pre-shop checklist

• Is this week’s menu decided?
• Did you check the pantry, fridge and freezer before writing the list?
• Have you eaten?
• Do you know this week’s grocery limit and how much you’ve already spent?
• Are the deals you’re tempted by actually on your list?
• Will you take 30 seconds to check the receipt?

Save money on groceries by tracking spending in Hano

Every method above depends on seeing what you actually spend on groceries — without logging becoming a chore.

• Snap the receipt, log it in seconds (Pro): Tap the camera button in the Assistant tab and photograph the receipt; Hano finds the total, the store name and the category, and saves it once you confirm. The photo isn’t stored. The full walkthrough is in our guide to logging expenses from a receipt.
• Log it in one sentence (Pro): No receipt? Type “farmers market 32” or “bakery 8” to the assistant. On the free plan you add the same entry manually with the + button, with no limit on the number of entries.
• Compare month to month: Switch the period between This Month, Last Month and Last 3 Months to compare your Groceries total and share. The Monthly Flow chart shows a six-month income and expense trend, and the Breakdown chart shows how much of your spending goes to groceries. All of this is on the free plan.
• “How much did we spend on groceries this month?” (Pro): Ask the assistant and it answers with your household’s total. Ask about last month to compare.
• Two shoppers, one budget: If one of you does the big weekly shop and the other picks things up on the way home, join the same household with a 6-digit invite code. Everyone logs their own spending, each entry shows who made it, and both trips land in the same grocery total. Pro covers two people, Max up to six. For the shared setup, see shared budgeting for couples.

Hano doesn’t connect to your bank; entries come from you or the assistant. That small moment of logging is also a moment to ask, “Did we really need that?” Download Hano for free — and if you want receipt scanning and the assistant, Pro starts with a 7-day free trial, no card required.
