Cost BuilderFree

Work out what a dish — or anything you make — really costs

Most costing goes wrong in the same place: the price on the invoice is for a 5kg bag and the recipe uses 180g — or the sheet of leather cost $90 and the wallet takes a tenth of it. Cost Builder does that arithmetic every time, whether what you make is food or not, so the margin you are looking at is the real one.

Free on every plan, including the free account.

How it works

  1. 1

    List what goes in

    Each ingredient or part, with what the pack costs and how much is in the pack.

  2. 2

    Say how much you use

    The per-unit cost is worked out from the pack price, so 180g of a 5kg bag is 180g of a 5kg bag.

  3. 3

    Set your sell price

    The margin appears next to it, in money and as a percentage. No hunting for it.

  4. 4

    Take the report

    A clean PDF you can hand to a partner, a bookkeeper or an accountant — or keep for the next time prices move.

Questions

Is it really free?
It is free on every plan, including the free account — not a trial. You need an account so your work saves, and that is all.
How do I work out food cost percentage?
Divide what the ingredients cost by what you sell the dish for, then multiply by 100. A burger whose ingredients cost $5.19, sold at $18.00 excluding GST, is 28.8%. The step people get wrong is the ingredient side: use the cost of the amount you use, not the price of the pack — 40g out of an $18 kilo of cheese is $0.72, not $18. That conversion is what this calculator does for every line.
Should the sell price include GST when I work out food cost?
Keep both sides of the sum on the same basis. If you are registered for GST you claim it back on what you buy, so use the GST-exclusive ingredient cost against a GST-exclusive sell price. Mixing them makes every dish look worse than it is.
Can I change a costing after I save it?
Yes. Open it again and edit it — you are not starting from scratch when a price changes.
Does it handle products that aren't food?
Yes. Nothing in it is food-specific — it is parts, pack sizes and amounts. Food is just where the maths bites hardest.
Can I use it as a raw materials calculator?
That is the same job under another name. A metre of webbing off a 30m roll and 180g out of a 5kg bag are one calculation, so wax, fabric, timber, beads and hardware all cost the same way ingredients do.
Will it tell me what to charge?
It shows the margin beside your sell price as you change it, so you can work backwards to the price that hits the margin you want rather than guessing and checking.

How to do it without the app

Cost Builder is one way. These explain the job itself — free to read, nothing to sign up for.
