Food is one of the biggest expenses in any household budget. According to WRAP, UK households spend a significant share of their income on food every month — and on top of that, the average family of four wastes around £1,000 worth of food every year without realising it. In the US, the equivalent figure is around $1,600 per family annually.
Food prices rose sharply in 2022–2023 and those increases have largely stayed. That makes managing your grocery budget more important than ever. The good news: you can cut spending significantly without eating worse — through smarter shopping habits and tools like the Fango app, which automatically tracks your groceries and reminds you before anything expires.
- A UK family of four wastes ~£1,000/year in food — halving this alone saves £400+ with no lifestyle change
- Shopping with a list + store-brand products are the biggest immediate wins — up to £100/month saved
- Buy discounted items and freeze them — saves 30–50% on meat and fish
- Track expiry dates automatically — Fango stops food waste without any daily effort
Where is the biggest saving potential?
Grocery savings come from two directions: buying smarter and wasting less. These two approaches reinforce each other — and combined, the potential is significant.
The food waste figure is particularly striking because it represents money already spent, then thrown away. WRAP estimates the average UK person wastes around £250 worth of food a year. Halving that waste alone would save a family of four over £400 annually — without changing a single shopping habit. The most practical tool for this is tracking expiry dates before things get forgotten — which Fango does automatically.
8 tips to cut your grocery bill
-
1
Always shop with a list — check what you have first big impact
Shopping without a list is the most expensive way to buy food. Impulse buys, duplicates and "just in case" items add up to tens of pounds or dollars a week. Before every grocery run, check your fridge, freezer and cupboards — then write down only what you actually need. Phone or paper doesn't matter: what matters is doing it every time.

2
Choose store-brand products save 20–40%
Supermarket own-brand products typically cost 20–40% less than named brands. In most categories — milk, yoghurt, pasta, tinned goods, frozen vegetables — quality is comparable. Switching to own-brand products even partially can save a family of four £50–100 a month without any noticeable difference in the food on the table.

3
Use reduced-to-clear items — and freeze them save 30–50%
Supermarkets discount products approaching their use-by date by 30–50%. Meat, fish and bread are the most common. The trick is simple: buy the discounted item and freeze it immediately when you get home. In the freezer, meat keeps for months — you get the discount price with no food waste risk.

4
Rough-plan your meals for the week significant
Meal planning doesn't mean a rigid minute-by-minute schedule. It's enough to know roughly what protein and vegetables you'll cook each day. This means you buy exactly what you need — and the shopping list stops growing with things you're not sure about. Even a loose weekly plan cuts impulse purchases dramatically.
-
5
Buy in season save 30–60%
Out-of-season tomatoes, strawberries or courgettes can cost several times more than the same produce bought in season. Fruit and vegetables are cheapest at their freshest. In summer, berries and salads; in autumn, root vegetables and squash — these are both the cheapest and best options. Stock up during peak season and freeze: summer berries keep well for months in the freezer.

Stop food waste — track expiry dates save £250/person/year
Food waste is the hidden saving that every household is leaving on the table. When food expires unnoticed at the back of the fridge, you pay for it twice: once at the shop and once when you throw it away. Fango solves this automatically: scan your grocery receipt with your phone camera, AI adds the products to your digital fridge, and you get a push notification before anything expires. Nothing to remember yourself.

7
Cook leftovers intentionally — not accidentally replaces meal costs
Leftovers are one of the cheapest lunches you can have. When you cook dinner, make more than you need — tomorrow's lunch is already ready. This cuts restaurant meals and supermarket meal-deal spending significantly. One replaced lunch out per week saves £10–15 — £40–60 a month, over £500 a year.

8
Compare unit prices — not pack sizes varies
A bigger pack isn't always cheaper — and the smallest isn't always the worst value. The only reliable comparison is the unit price (price per kg or per litre), which supermarkets are required to display on shelf labels. Always compare unit prices, not the total cost of different pack sizes. For cheese, bread, and many staples, the difference between sizes can be surprisingly large.
Automatic reminders before food expires
Tip six — cutting food waste — is arguably the most impactful of the eight, because it works every week, after every shop. The problem is practicality: checking expiry dates manually is tedious, and in a busy household things simply get forgotten at the back of the fridge.
Scan your grocery receipt with your phone camera — AI identifies your products and adds them to your digital fridge automatically. You get a push notification 1–14 days before anything expires. No sign-up. All data stays on your device.
