Markup, margin, and food-cost percentage can all describe the same menu, but they do not describe the same relationship. If you use the words interchangeably, two correct calculators can appear to disagree.

Food-cost percentage

Food-cost percentage asks how much of the selling price is consumed by ingredients.

Food-cost percentage = food cost ÷ selling price × 100

If a menu costs $26.93 per guest and sells for $68:

$26.93 ÷ $68.00 ≈ 39.6% food cost

The remaining 60.4% is not profit. It still has to cover labor, packaging, rentals, delivery, overhead, tax treatment where applicable, waste outside the recipe, and the return the business needs.

Markup

Markup compares the amount added with the cost you started from.

Markup = (selling price − cost) ÷ cost × 100

Using the same food cost and selling price:

($68.00 − $26.93) ÷ $26.93 ≈ 152.5% markup on food cost

Thirty percent food cost is not a 30% markup. A 30% markup on $26.93 would produce a selling price of only $35.01.

Food-only gross margin

Margin compares the amount left after food cost with the selling price:

Food-only margin = (selling price − food cost) ÷ selling price × 100

For the same menu:

($68.00 − $26.93) ÷ $68.00 ≈ 60.4% food-only margin

This is simply the other side of the 39.6% food-cost percentage. It is still not net profit because only food cost has been removed.

Price from a target

When you start with a target food-cost percentage, divide the food cost by the target written as a decimal:

Selling price = food cost per guest ÷ target percentage
$26.9331 ÷ 0.30 ≈ $89.78 per guest

This calculation is a decision aid, not a command. If the market will not support the result, the honest choices are to change the menu, change portions, negotiate buying, revise the target with full knowledge of the consequence, or decide the event is not a fit.

Pick one language for the quote review

For catering work, food-cost percentage is often the clearest way to compare different menus against the same internal target. Markup remains useful when you are deliberately pricing from a cost base. Margin is useful only when everyone agrees which costs have been removed.

Write the chosen target beside the quote. Also name what is outside the number. A percentage without its cost boundary is a confident-looking ambiguity.
