Menu item profitability matrix: act on popularity and contribution margin together
Build a popularity-by-margin matrix from real sales, assign every dish to a quadrant, and apply disciplined re-engineering rules.
The matrix should be built by section: starters compete with starters, not with bottles of wine. If eight mains sell 1,600 units, equal popularity is 12.5%; a practical threshold might be 70% of that share, or 8.75%. For margin, use the median contribution of the eight mains so one premium steak does not distort the cut-off. Thresholds are decision aids, not laws: an allergen-friendly dish selling 6% may deserve to stay because it serves a strategic guest need.
Read the four quadrants as jobs, not labels
- Stars—high popularity, high margin: keep quality and availability stable, give them visible placement, and test only modest price movement. Their main risk is damaging a proven promise.
- Plowhorses—high popularity, low margin: protect recognition while improving economics through a €0.50–€1.50 price step, portion control, side choice, or supplier specification.
- Puzzles—low popularity, high margin: clarify the name, photograph or describe the value, move the item, and give servers one honest recommendation cue before changing the recipe.
- Dogs—low popularity, low margin: remove, seasonalise, or rebuild only when the item lacks a strategic function. Count shared ingredients and kitchen complexity before cutting it.
Plot one section without confusing margin and markup
A neighbourhood restaurant reviews four mains after 28 days. The popularity threshold is 9% of main-course units and the contribution threshold is €13.00. These figures demonstrate the method and are not a verified customer case.
| Roast chicken | 18% mix · €14.20 contribution | Star: maintain execution and test no more than €0.50 |
|---|---|---|
| House burger | 24% mix · €9.80 contribution | Plowhorse: examine portion, fries, and a €1 price step |
| Sea bass | 6% mix · €18.40 contribution | Puzzle: improve description and server cue for four weeks |
| Mushroom pasta | 5% mix · €8.90 contribution | Dog unless it covers an important vegetarian need |
The burger is not ‘better’ than the sea bass merely because it sells four times as often. Their jobs differ, so the burger needs margin repair while the sea bass needs a demand test.
Turn the chart into controlled menu experiments
- 1Clean the inputs. Use net prices after discounts, current standard recipe costs, and item-level units. Merge duplicate POS buttons and remove days with closures or an exceptional fixed menu that would skew ordinary demand.
- 2Set local thresholds. Calculate equal-share popularity within each section and use 70% of that figure as a starting line. Use median euro contribution for margin, then document strategic exceptions before seeing the quadrants.
- 3Assign one intervention. Give every target one change only: price, portion, description, placement, recommendation, or deletion. Cap a first price test around 3–5% and never shrink a signature dish silently.
- 4Measure the new mix. After 28 comparable days, compare units, section share, unit contribution, and total contribution. Keep a change only when the combined economics improve without a material rise in complaints or returns.
FAQ
- Should I use gross profit or contribution margin?
- Use unit contribution margin—net selling price minus variable food and packaging cost—for the plot. It does not claim to be full profit because labour, rent, and overhead remain. Add complexity as a separate decision factor.
- What if an item changes quadrant each month?
- Use a rolling 8–12 week view or combine comparable four-week periods. Low unit counts create noise. Do not redesign a dish because one rainy weekend pushed its mix from 9.2% to 8.7%.
- Can drinks and food share one matrix?
- No. Their purchase economics, sales occasions, and natural volumes differ. Build separate matrices for starters, mains, desserts, alcoholic drinks, and non-alcoholic drinks where volume allows.
- When should a dog stay on the menu?
- Keep it when it provides a necessary dietary option, uses existing mise en place, completes a set menu, or has seasonal significance. State that role explicitly and review whether a simpler item could serve it.
