The Cheapest Foods to Buy When Money Is Tight

When money is tight, the useful question is not “what is cheap?” It’s “what is cheap per meal, filling, and doesn’t spoil before I eat it?”

Those three conditions rule out a lot of things that look cheap on the shelf. A reduced bag of salad is cheap and is not food you can build a week on.

Prices vary too much between countries and shops for me to give you numbers, so this is a list of categories and the reasoning behind them. Check them against your own prices.

The base: things that never spoil

These are what a tight-budget week is built on. They cost little per serving, keep for months, and turn small amounts of everything else into full meals.

Rice. Probably the cheapest way to fill a plate. Buy the largest bag you’ll get through.

Dried pasta. Same logic. Ignore the shaped and flavoured versions.

Oats. Very cheap per portion and genuinely filling. Breakfast for a month costs remarkably little.

Dried lentils. Cheaper than tinned, cook in twenty minutes, no soaking. Red lentils collapse into sauces and stretch a small amount of meat a long way.

Dried beans and chickpeas. Cheaper than tinned if you’ll plan ahead enough to soak them. Tinned if you won’t — still good value, and a tin you actually use beats a bag you don’t.

Flour. If you’ll use it, it’s the cheapest bread there is. If you won’t, skip it — the cheapest ingredient in the world is worthless unopened.

The protein that isn’t expensive

Eggs. The best value protein in most shops, and they work at any meal.

Tinned fish. Sardines and mackerel are usually far cheaper than tuna and keep indefinitely.

Chicken thighs and drumsticks. Consistently cheaper than breast, harder to overcook, and better in anything slow-cooked.

Whole chicken. Cheaper per kilo than any cut, and gives you two or three meals plus stock.

Mince, stretched. Half mince and half lentils in a bolognese cuts the cost substantially and most people can’t tell.

Vegetables that earn their place

Onions, carrots, potatoes, cabbage. The cheap, keep-for-weeks base of most cooking. A bag of onions is one of the highest-value purchases in a shop.

Frozen mixed vegetables, peas, sweetcorn, spinach. Usually cheaper than fresh, don’t spoil, and let you use exactly what you need. For anything going into a cooked dish, frozen is the better buy on both cost and waste.

Tinned tomatoes. The base of an enormous number of cheap meals.

Fruit that doesn’t die in three days

Bananas and apples. Cheap, filling, and they survive a week.

Frozen berries. Far cheaper than fresh, and better for anything you’re not eating raw.

Fresh soft fruit is where tight budgets leak. It’s expensive and it spoils fast.

Cheap on the shelf, expensive per meal

Worth naming, because these look like savings:

• Bagged salad. Costs a lot per kilo, spoils in days, and doesn’t fill anyone up.
• Fresh herbs in packets. Expensive and usually half-wasted. Frozen or dried, or a pot on the windowsill.
• Ready meals on offer. Sometimes genuinely good value; usually more per serving than cooking the same thing, and less food.
• Anything pre-prepared — grated cheese, sliced vegetables, diced onion. You’re paying a large premium for a few minutes of work.
• Multipack snacks. Cheap per packet, expensive per calorie, and they don’t replace a meal.

The two rules that matter more than the list

Judge by unit price, not shelf price. The price per kilo is on the shelf label. It’s the only honest comparison, and it frequently contradicts the headline price.

Buy big only on what doesn’t spoil. Bulk saves money on rice, pasta, oats, tins and frozen goods. It loses money on fresh produce and dairy, because the surplus gets thrown away — and food you binned costs more than the expensive version you ate.

A tight-week trolley

If you had to fill one and stop thinking about it:

Rice, pasta, oats, red lentils, tinned tomatoes, tinned beans, tinned fish, eggs, a bag of onions, carrots, potatoes, cabbage, frozen mixed veg, frozen peas, bananas, a block of cheese, chicken thighs, oil, salt.

That’s a week of real dinners with almost nothing wasted, and every item on it does more than one job.
