What this calculator does
Pricing a cake means covering three things: ingredients, your time, and the overhead that keeps the kitchen running. Ingredients at $35 plus three hours at $25 comes to $110, and a 10% overhead takes the total cost to $121.
Margin is then applied by dividing rather than multiplying, which is the part most often got wrong. A 30% margin means the cost is 70% of the price, so the price is $121 divided by 0.7, which is $172.86. Multiplying the cost by 1.3 would give $157.30 and a margin of only 23%.
The formula
Ingredient cost is added to labour, which is hours multiplied by the hourly rate. The overhead percentage is applied to that subtotal to give total cost. The sale price is the total cost divided by one minus the margin, which produces a genuine margin on the sale price rather than a markup on cost. Price per serving divides the result by the serving count.
| Term | Meaning |
|---|---|
| Margin | Profit as a percentage of the sale price. Calculated by dividing cost by one minus the margin. |
| Markup | Profit as a percentage of cost, which is a different and larger-looking number for the same money. |
| Overhead | Costs not attributable to one cake: power, equipment wear, insurance, packaging, wasted stock. |
| Labour rate | What you are paying yourself per hour, which belongs in the cost rather than being left as whatever is left over. |
The inputs explained
| Field | What to enter |
|---|---|
| Ingredient cost ($) | Ingredient cost for this cake. |
| Labour hours | Hours of work, including decorating, shopping and cleaning up rather than baking time alone. |
| Labour rate ($/hr) | Your hourly rate. |
| Overhead (packaging, utilities, delivery) (%) | Overhead as a percentage of ingredients plus labour. |
| Target profit margin (%) | Target profit margin as a percentage of the sale price. |
| Servings | Number of servings, for the per-serving figure. |
When to use it
Quoting a custom cake
The per-serving figure is what customers compare against, and having it derived from actual costs rather than guessed makes a quote defensible.
Checking whether a price is sustainable
Working backwards from a price you already charge shows what margin it actually leaves once your own time is properly costed.
Deciding whether to take an order
A complex cake with many decorating hours can price above what a customer will pay, and knowing that before accepting is better than discovering it afterwards.
Worked examples
Every figure in the tables below is produced by this page’s own calculator at build time, so the numbers and the tool always agree. Select any row to load that scenario.
What price does each target margin give?
The same cost base at three different target margins.
| Target margin | Suggested sale price | Price per serving | Total cost (with overhead) | Profit at this price |
|---|---|---|---|---|
| 20% | $151.25 | $7.56 | $121.00 | $30.25 |
| 30% | $172.86 | $8.64 | $121.00 | $51.86 |
| 40% | $201.67 | $10.08 | $121.00 | $80.67 |
Questions
What is the difference between margin and markup?
Margin is profit as a share of the sale price; markup is profit as a share of cost. A 30% margin is a 43% markup on the same money. Confusing them systematically under-prices, which is why this calculator divides by one minus the margin rather than multiplying.
Should I charge for my own time?
Yes, at a real hourly rate, and count all of it: shopping, baking, decorating, delivery and cleaning. Leaving labour out of the cost means the profit figure is really just wages, and usually poor ones once the hours are honestly counted.
What should the overhead percentage be?
It depends on the operation, but 10 to 20% of ingredients plus labour is a common range for a small home-based operation. It covers power, equipment depreciation, packaging, insurance and the ingredients that spoil before use. Track actual costs over a few months rather than guessing indefinitely.
How do I price per serving?
Divide the total price by the serving count, which the calculator does. Customers frequently compare on this figure, so it is worth knowing where yours sits. If it looks high, the answer is usually to examine the hours rather than to cut the rate.
