A family meal budget planner that survives a real supermarket
Rent is decided once. Food is decided again every few days, in a shop, while tired, usually with someone asking for something. That is why it is the line that breaks, and also why it is the line where the money actually is.
Why food budgets fail when other categories hold
A monthly food budget is a strange instrument: it sets a number for a period you never shop in. Nobody does one grocery run for October. You shop weekly, sometimes twice weekly, and each of those trips is a fresh negotiation with a number you set four weeks ago and cannot remember.
Three things make it worse than any other category.
- The receipt is not one thing. A single supermarket trip contains food, cleaning products, toiletries, maybe a birthday card. Filed as "groceries", your food number is wrong all year.
- It hides top-ups. The big shop gets counted. The three small trips for milk, bread and something forgotten do not, and together they are often a quarter of the total.
- It is not really discretionary. You cannot decide to skip food the way you can skip a takeaway, so "spend less" is not advice. What works is deciding earlier, not deciding less.
Set a weekly number, not a monthly one
This is the single change that makes food budgeting work, and it costs nothing. Take your monthly food figure and divide it by the number of weeks you actually shop in. That weekly number is small enough to hold in your head at the shelf, which the monthly one never was.
If you do not know your monthly figure, do not guess it. Add up the last four weeks of food spending from your bank app, including the top-ups and the takeaways. Most people are out by a wide margin in the same direction, and finding the real number is most of the work.
Count takeaways and lunches at work in the food number. Splitting them into a separate "eating out" line is how a food budget stays technically green while the money leaves anyway. One number for everything you eat is harder to fool.
Plan the meals you will actually cook
Meal planning fails when it is aspirational. Seven ambitious dinners on a Sunday becomes three, then a takeaway, then a shop full of ingredients that go off. A planner that works looks boring on purpose.
- Plan five dinners, not seven. Leave two open for leftovers, a late night or a change of plan. Those two nights happen whether or not you planned them.
- Repeat deliberately. The same four or five dinners on rotation is not a failure of imagination, it is what makes the shopping list predictable and the cost stable.
- Shop the cupboard first. Write the list after looking at what is already in the house. This one habit is usually worth more than any coupon.
- Price per portion, not per pack. The bigger pack is cheaper per unit and only cheaper in reality if you eat all of it.

| Difference against budget |
The "food only?" column is the important one
When you get back, split the receipt. Write down what was actually food and what was cleaning products, nappies, batteries and the rest. It takes thirty seconds and it is the difference between knowing your food budget and guessing at it.
Almost everyone who does this for the first time discovers their real food spending is lower than they feared and their household spending is higher than they thought. Both of those are useful, and neither shows up while one receipt counts as one thing.
When a week goes over
Carry it forward to the next week rather than writing the month off. A week that runs 20 over is a week where next week's number is 20 smaller, and that is a completely survivable adjustment. Declaring the month ruined is what turns one bad week into a bad quarter.
If every week runs over, the budget is wrong rather than your behaviour. Raise the number to what you actually spend and cut somewhere you decide once, not somewhere you have to decide again every Tuesday.
When paper stops being enough
Paper works, and the writing is part of why it works. What wears people down is the arithmetic: splitting every receipt by hand, remembering the two top-ups, keeping a running total of what is left this week, and tracking the cash spent at a market stall that never appears in a bank app at all.
That is the part Wallety takes over. It lets you split a single transaction across categories, so one supermarket trip can be part food and part household. It tracks cash alongside cards, sets monthly budgets per category with a daily pace so you can see whether this week is on track, and warns you before you go over rather than after. Everything stays on your phone, with no account and no bank login.
If you would rather see how the options compare first, including who my own app is wrong for, that is written up in how to choose a budget planner app.
Where food fits in the wider budget
A food number only means something once you know what is left after the bills that were never optional. If you have not separated committed money from spendable money yet, do that first: it is the same exercise one level up, and it is written out with its own printable in a month to month budget planner that survives past week two.
