There is no universal customer count for breaking even in meal prep; the honest formula is new fixed costs divided by contribution per bag, then by bags per customer per week. For an operator adding a prepaid line to a kitchen already paid for, the answer is often startlingly small, because each bag only has to clear its own variable costs.
Somewhere on a forum tonight, a stranger will answer this question with a confident round number. Ignore them. I ran three meal prep brands from one kitchen, and I can tell you the count differs wildly between two owners on the same street. What never differs is the arithmetic. Here it is, short enough to do on a napkin.
What is the break-even formula for meal prep?
Divide the fixed costs your meal prep line adds by the contribution each bag makes, and you have your break-even in bags; divide again by bags per customer per week for the customer count. Contribution per bag means the dish price minus ingredients, packing, and the delivery share for that bag. Fixed costs mean only what the line genuinely adds: extra staff hours, new equipment, the software, the ads you commit to monthly. Notice what does not belong in the fixed column for an existing venue: rent, licences, and the core crew, because your current trade already pays them. That single accounting choice is why the same line breaks even at a handful of customers inside a working kitchen and at hundreds for a start-up signing a fresh lease. Put your own numbers through the operator profit calculator and the division is done for you.
Why do existing kitchens break even so much sooner?
Because a start-up must climb over the whole cost mountain before its first profitable bag, while an existing kitchen has already climbed it. A new founder needs the subscriber book to carry rent, fit-out, licences, insurance, and a crew, all before profit begins. An operator bolting a prepaid line onto a venue the lunch service already funds needs each bag to clear only its own ingredients, packing and courier share. In practice that means the bolt-on case often breaks even within its first stable weeks, at a customer count you could assemble from regulars and referrals alone, no advertising involved. This asymmetry is the entire strategic argument for adding a meal prep line to a kitchen you already run instead of building a meal prep company from zero. The model rewards whoever already owns the fixed costs.
Which numbers move your break-even most?
Three, in order of leverage. First, contribution per bag: a small rise in dish price, or a drop in food cost toward the quarter-of-price target, cuts the required count directly. Second, drop density: two bags landing at one address split a courier fee that one bag would carry alone, so households and offices are worth more than their order value suggests. Third, bags per customer: a subscriber eating five days a week advances you toward break-even five times faster than a twice-a-week dabbler, which is why plan design quietly matters more than marketing volume. And one number moves it in the wrong direction: churn. A customer who leaves before repaying their acquisition cost raises everyone else’s burden. Winning durable customers, not just customers, is the real assignment, and that playbook is here.
A worked example you can copy
Say your plan sells at a dish price where each bag contributes a few dollars, about the price of a coffee and a sandwich, after ingredients, packing and its courier share. Say the line adds one part-time packer and a modest ad commitment as genuinely new fixed cost each month. Divide the monthly fixed addition by the per-bag contribution and you get bags per month; divide by roughly twenty eating days and a one-bag-a-day subscriber, and you land on your customer count. Run it with your real prices and the pattern repeats: for a working kitchen the answer is usually tens, not hundreds. Then stress it: halve your drop density, add a slow month, let food cost drift a few points. If the count still looks reachable from your own regulars, the line deserves a pilot week. If not, fix contribution first, count later. The maths behind every row lives in is a meal prep business profitable.
