What a break-even point actually measures
A break-even point is the moment two different costs meet: the cost of cooking a meal at home and the cost of ordering it in. Below that point, cooking works out cheaper. Above it, ordering does, once you account for how much of an ingredient or a piece of kitchen equipment actually gets used. The cook vs order break-even calculator takes your own numbers and finds that point for you, rather than leaving you to guess whether tonight's curry is worth making from scratch.
This matters because most households already know, roughly, that cooking is cheaper than ordering. What they don't know is by how much, or at what point that stops being true. A one-off dinner for two might not justify buying a jar of a spice you'll use once. The same jar, spread across six meals over a month, changes the arithmetic completely.
Why the sums are more than a takeaway receipt versus a supermarket receipt
Comparing a £9 takeaway to a £2.50 home-cooked portion looks simple until you notice what's missing from the home-cooked side. A recipe rarely uses a whole packet of anything. Half a bag of rice, a third of a jar of curry paste, and a single stock cube from a box of ten all carry a cost that doesn't disappear just because you didn't use the rest that evening.
The break-even calculation spreads that cost properly. It asks how many meals a given shop actually covers, then divides accordingly, so the price per portion reflects what you genuinely spent on that dinner rather than what the whole shopping trip cost. That's a fairer comparison, and it's usually the one that convinces people cooking is worth it more often than they assumed.
The costs people forget to count
- Part-used ingredients: spices, oils, sauces and stock that last well beyond one meal but were bought for it.
- Your time: not every household wants to price this in, but thirty minutes of chopping and stirring has some value, even if it's just \"time I'd rather not spend on a Wednesday\".
- Energy: an oven left on for an hour costs more than a hob used for ten minutes, and that difference adds up across a week.
- Waste: ingredients bought for one recipe and left to go off in the fridge effectively cost more than they should have.
Common mistakes when working this out
The most frequent error is comparing a single meal in isolation, as though it were the only time that shopping basket gets used. A recipe that needs a £4 jar of harissa looks expensive against a £7 takeaway curry, right up until you notice the same jar covers four more dinners this month. Spread across five uses, it adds 80p a portion, not £4.
A second mistake runs the other way: assuming home cooking always wins because it usually does. Some meals genuinely don't clear the break-even point, particularly for one person cooking a dish that needs six ingredients bought in full-size packs. Pretending otherwise just makes the calculator feel wrong when the answer doesn't match what you hoped to hear.
A third is leaving out the ordering side of the comparison. Delivery fees, service charges and the almost automatic extra side or drink all raise the real cost of a takeaway well above the headline menu price. Households that only compare the main dish tend to underestimate what ordering in actually costs them over a month.
The comparison only works as well as the numbers you put into it. If your typical takeaway order includes a side and a delivery charge, put those in. If your recipe uses a spice jar you'll finish over several weeks, split its cost across the meals it actually serves.
How to use the numbers
Once you know your break-even point, the practical step is deciding which meals sit clearly on the cooking side of it and building your week around those first. A dinner that only just clears break-even is a reasonable one to order in on a night when there's genuinely no time to cook, without treating that as a failure of planning.
Batch cooking shifts the maths further in favour of home cooking, because it spreads a fixed set of costs, part-used jars, an oven already heated, thirty minutes of prep, across more portions. Cooking a large batch of chilli that becomes three dinners instead of one changes the cost per portion more than almost any single ingredient swap could. The batch cooking session planner is built around exactly that kind of spreading.
It's also worth running the numbers on a genuine order you'd actually place. The takeaway vs home cooking cost comparison tool works alongside the break-even calculator for this, letting you compare a specific order against a specific recipe rather than general assumptions about which is cheaper.
Where this fits alongside your other planning
A break-even figure is most useful as one input into a week's planning. Some evenings the time saved by ordering is worth more to your household than the money saved by cooking, and that's a reasonable trade-off to make deliberately. Knowing the actual break-even point just means you're choosing with the numbers in front of you.
If you're trying to fit this into a wider budget rather than a single meal decision, the weekly meal budget planner takes the same kind of thinking and applies it across a full week's shop, so you can see where the savings from cooking actually land over time.
Like any calculator built from the figures you enter, the cook vs order break-even calculator can only work with what it's given. Prices vary between shops and regions, and a recipe you tweak slightly will shift the result. Treat the output as a working estimate to plan around, and check it against your own receipts every so often to keep it useful.
