Compare the meals you would actually change
You do not need to stop enjoying restaurants to understand your food spending. Start with one or two meals you currently buy, then compare them with something you would realistically cook. Keep social meals or useful convenience in the plan if you value them.
Weekly difference = (all-in eating-out cost per person − home-cooked cost per serving) × people × meals replaced per week. Include known tax, tips and delivery fees once. For a shared order, divide its total by the people it feeds before entering a per-person price. Use the same number of people for every meal in a calculation.
Use the free eating out vs cooking calculator
The starting prices are fictional euro amounts, not local averages. Replace them with receipt totals and your own ingredient costs. An average month uses 52 weeks divided by twelve; four weeks is a separate result. You can compare one, two or three replacements without committing to any of them.
Eating out vs cooking calculator
Compare the meals you want to change, using your own prices and a plan you can actually keep.
Fictional euro example, not local price averages. Replace the values with your own.
Use the same group for each meal. Enter 1–20 people and 0–21 meals you would otherwise buy. Include known tax, tips and fees once; split shared order fees per person.
Number format: 1,234.56. Use zero or a positive amount up to one billion and the currency’s decimal places. Changing currency relabels amounts; it does not convert them. Use one currency per audit.
Potential cost reduction with your plan
Weekly cost of the meals you change
Try a smaller or larger change
Each row uses your prices and household size. Choose only a number of meals you would really replace. Selecting a row updates the plan above.
| Meals to replace each week | Per week | Average month | Per year |
|---|---|---|---|
| EUR 12.00 | EUR 52.00 | EUR 624.00 | |
| EUR 24.00 | EUR 104.00 | EUR 1,248.00 | |
| EUR 36.00 | EUR 156.00 | EUR 1,872.00 |
Help me work out a serving cost
Include ingredients used and any discarded share; exclude usable stock for other meals. Divide by the portions actually eaten, from 1 to 1,000. The helper rounds up to the nearest currency minor unit. It is not your whole grocery checkout bill.
Cost per eaten serving: EUR 6.00
Add preparation time, separately
Optional: enter 0–1,440 minutes for the whole household meal, not per person. Weekly time is this figure × meals replaced. It does not change the money calculation or turn time into wages.
Additional minutes per week: —
Weekly difference = (all-in eating-out cost per person − home cost per serving) × people × meals replaced.
An average month is 52 weeks ÷ 12; a year is 52 weeks. Results round to the currency’s minor unit. Only entered costs count: no automatic live prices, nutrition, equipment, energy, interest or investment returns. A projected reduction is not cash already saved. Upfront grocery spending may be higher than the ingredient cost used here.

A worked example: two meals, €24 a week
| For one person | Two meals per week | Cost |
|---|---|---|
| Buy both meals | 2 × €18 | €36 |
| Cook both meals | 2 × €6 | €12 |
| Potential weekly difference | €36 − €12 | €24 |
If those prices and choices stayed the same for 52 weeks, the difference would be €1,248 a year, or €104 per average month. Four weeks would be €96. These are scenarios, not verified savings or live restaurant prices.
For a serving-cost check, a fictional €24 batch eaten as four portions costs €6 per portion. If only three portions are eaten and the fourth is discarded, the same batch costs €8 per eaten portion. The helper counts that waste; it rounds a fractional result up to the currency’s smallest unit.
Count leftovers, time and checkout spending fairly
Suppose you pay €20 for groceries, use €12 for the meals being compared and keep €8 of usable ingredients for later. Record the full €20 as an actual expense. The meal comparison uses the allocated €12, so its €24 cost difference does not mean your bank balance immediately improves by €24. Ingredients already in your cupboard are not automatically free either.
Plan around portions you will actually eat. EPA’s guidance recommends checking existing stock, shopping for planned meals and buying in bulk only when you can use the food. The source is linked below. This calculator does not set a nutritional target or prescribe a local grocery budget.
Cheap prepared food, a kitchen purchase, wasted ingredients or a difficult schedule can change the result. Let higher home costs remain visible. You may also enter extra preparation and cleanup minutes for the whole household meal; time stays separate from money. Only energy or equipment costs you include yourself enter the price comparison.
Try a seven-day food-spending experiment
At the start, look at recent receipts and choose two specific meals to change. During the week, shop from a short list and note what gets eaten or discarded. At the end, compare the actual grocery and dining totals with your plan, then decide whether the change was worthwhile.
Fit the meals into your monthly budget. Use the payday planner to check what is available before buying groceries, and a weekly review to catch differences. A potential reduction becomes useful only when actual spending falls and you choose what to do with the money.

Questions about eating out and cooking costs
Is cooking always cheaper for one person?
No. Compare the food you actually buy with portions you will really eat. Cheap prepared meals, waste, equipment needs and your schedule can change the result. Higher home costs stay negative in the calculator.
How much could replacing two takeaway meals save?
Using fictional prices of €18 outside and €6 at home for one person gives (€18 − €6) × 2 = €24 weekly. That is €96 for four weeks or €104 per average month, if the pattern continues.
Should I count the entire grocery receipt?
Record the full checkout payment in your expense tracker. For the meal comparison, allocate ingredients used plus any discarded share; exclude usable stock for other meals. The two figures answer different questions.
Does the calculator count my time?
You can enter extra cooking and cleanup minutes per replaced household meal. They are shown separately per week, without conversion to wages or a change to the money result.
Is this calculator free and private?
Yes. It runs in your browser without an account or bank connection. Inputs are not uploaded or saved. Print your plan if you want a copy; reloading restores the fictional example.
