Event Break-Even Calculator
Day BookHow many have to go out of the window before the pitch is paid.
A pitch fee arrives as a single number in July and gets answered on instinct. Nobody works out how many plates it actually costs, because that means knowing what a plate contributes after what went into it — and that figure lives in four places, none of them together.
Somebody offers you a pitch for the weekend. This works out how many have to sell before the day has paid for itself at the mix you expect, draws where that sits against the day you are planning, and costs the prep that does not sell at what it cost you rather than at what it would have made.
About this tool
Event Break-Even Calculator: what it solves
A day at a festival has one piece of arithmetic in it and almost nobody does it. Everything sold contributes its price minus what that one cost to make. The pitch fee, the fuel, the propane and the extra pair of hands do not move with sales at all. So the day breaks even at the fixed cost divided by what a unit contributes — and with more than one thing on the menu, a unit means one unit at the mix being expected, which is an assumption this states on the page rather than burying. It rounds that number UP, because half a plate does not pay half a pitch fee and a break-even that has not broken even is worse than none. Prep that does not sell is costed separately and at what it cost, never at what it would have sold for, because that money was never anybody’s. It is the only tool here that draws its answer, and the line is straight because the arithmetic is — nothing is fitted, smoothed or projected. It forecasts no crowd, suggests no price, and will not tell you whether to take the booking.
One piece of arithmetic decides the day, and almost nobody does it
The pitch fee does not care how many people come. Neither does the fuel, the propane, or the extra pair of hands you booked.
Everything you sell contributes its price minus what that one cost to make. Stack those contributions up until they cover the costs that do not move, and that is the moment the day starts paying you.
Fixed cost divided by what one unit contributes. That is the number. It takes thirty seconds once you have the figures in one place, and the reason it does not get done is that the figures are never in one place — the pitch fee is in an email, the food cost is in your head, and the day is on Saturday.
With a menu, “a unit” means something specific
If you sell one thing, a unit is that thing and the arithmetic is clean.
Sell four things and a unit means one unit at the mix you are expecting — six tacos to every burrito, or whatever your Saturday looks like. That assumption changes the answer materially, and it is an assumption rather than a fact.
So it is on the page, in the open, where you can change it and watch the number move. Not buried in a setting, and not quietly averaged behind your back. If you think the mix will be different at this event, say so and see what it does.
It rounds up, and that is not politeness
Half a plate does not pay half a pitch fee.
A break-even of 87.3 rounds to 88. A break-even that has not actually broken even is worse than no number at all, because you will stand there at 87 thinking you are square when you are not.
Prep that does not sell is costed at what it cost
Not at what it would have sold for.
That distinction matters and it is where a lot of event arithmetic goes soft. Two hundred portions prepped, a hundred and forty sold, sixty in the bin. Those sixty cost you what the ingredients cost. They did not cost you sixty times the menu price, because that money was never anybody’s — nobody was standing there with cash for it.
Costing waste at the selling price makes every slow day look like a disaster and every good day look better than it was. This costs it at cost.
The line is straight because the arithmetic is
This is the only tool here that draws its answer.
The line is straight, and it is straight because contribution per unit is a constant multiplied by a count. Nothing is fitted to it, nothing is smoothed, and no curve has been drawn through anything. What you are looking at is a division with a ruler through it.
What it replaces
The decision made on gut, which is right often enough to keep being made. Or the arithmetic done on Sunday night, after the event, when it is a fact rather than a decision.
You set your costs and your menu once. Each event is a pitch fee and a mix.
Who it is for
Food trucks, caterers, market and festival vendors — anybody paying to be somewhere for a day and selling on the day.
What it will not do
It forecasts no crowd. It does not know how many people are coming, and neither does anybody selling you software that says it does.
It suggests no price. What you charge is yours.
It will not tell you whether to take the booking. It tells you how many have to go out of the window before the pitch is paid. Whether that number is reachable is a judgment about the event, the weather, the town and your own read on it — and you have all four.
Nothing you type is sent anywhere. The arithmetic runs in your browser, which also means it works in a field with one bar of signal. Close the tab and it is gone.
Yours would be built the same way.
This one runs on made-up data. The version built for your business runs on yours, and you own it outright. Builds start at $1,300. That is a floor, not a quote. What yours costs is agreed before any work begins. The first conversation is free.
