One cost, two different 60% choices
For a fictional $60 fully modeled cost:
| Pricing choice | Calculation | Price | Amount above modeled cost |
|---|---|---|---|
| 60% markup | $60 × 1.60 | $96 | $36 |
| 60% margin | $60 ÷ 0.40 | $150 | $90 |
A $96 selling price has a margin of $36/$96 = 37.5%, not 60%. A $150 selling price has markup of $90/$60 = 150%. These examples do not recommend either price.
Formulas to keep beside the input
Markup = (price − cost) ÷ cost
Margin = (price − cost) ÷ price
Margin from markup = markup ÷ (1 + markup)
Markup from margin = margin ÷ (1 − margin)
Enter percentages as decimals for arithmetic: 60% becomes 0.60. A target margin below 100% is necessary for the last denominator to stay positive. For these ratio comparisons, cost and price must be positive; a zero cost does not produce a meaningful markup percentage.
Decide what “cost” includes
If the $60 contains only ingredients, the $36 above it still needs to fund labor, packaging and other costs. If $60 includes every modeled order cost, the $36 has a different interpretation. Label the cost scope whenever you show the percentage.
“Gross,” “contribution” and “net” describe different scopes in financial reporting. This arithmetic reference does not supply an accounting classification or prove actual profit. Reconcile business reporting with your accountant's approach.
Catch the common entry error
A baker wants 30% margin but types 30% into a markup field. At $100 cost, the tool gives $130. The margin is $30/$130 = 23.08%. A 30% margin would require $100/0.70 = $142.86, rounded for display.
The remedy is a clearly labeled method selector or two visibly different input fields, not a vague field called “profit percentage.” Show the computed price and the resulting other percentage so the choice is auditable.
