Nearly 73% of menu items fail to generate meaningful profit within their first year. A poorly performing dish hits you with a double penalty: wasted investment in development plus lost opportunity costs. Simple math reveals whether each dish earns its menu real estate.
Measure the performance of each dish
Fair assessment requires three core numbers: sales volume, profit generation, and menu space allocation.
💡 Example:
Restaurant with 25 dishes on the menu, 1000 covers per month:
- Average per dish: 40 sales per month
- Dish A: 15 sales (37.5% of average)
- Dish B: 65 sales (162.5% of average)
Dish A is clearly underperforming.
Calculate the profit contribution per dish
Popularity doesn't guarantee profitability. High-volume dishes with razor-thin margins can drain resources just like slow movers.
Profit contribution formula:
(Selling price excl. VAT - Ingredient costs) × Number of sales = Total profit contribution
💡 Comparison example:
Two dishes with different performance:
- Pasta (popular): €16.51 excl. VAT - €5.20 costs = €11.31 profit × 80 sales = €904.80
- Duck breast (exclusive): €27.52 excl. VAT - €9.10 costs = €18.42 profit × 12 sales = €221.04
The pasta deserves its spot, the duck breast is questionable.
The 80/20 rule for menus
Typically, 20% of your dishes drive 80% of revenue. From analyzing actual purchasing data across different restaurant types, this pattern holds remarkably consistent.
- Rank all dishes by total profit contribution
- Calculate running totals until you hit 80% of dish profits
- Items below this threshold become removal candidates
⚠️ Note:
Seasonal fluctuations matter. Today's dud might become next quarter's star performer. Analyze at least 6 months of historical data before making permanent cuts.
The cost of a menu spot
Each menu position carries hidden costs: inventory investment, prep time, staff training, and customer decision fatigue.
Simple benchmark: dishes representing less than 2% of total sales should justify their existence or face elimination.
💡 Menu spot calculation:
With 20 dishes on the menu:
- Ideal per dish: 100% ÷ 20 = 5% of sales
- Minimum acceptable: 2% of sales
- Dish with 1% = candidate for removal
Replacement test: what can go in its place?
Don't just subtract - strategically replace. New dishes require development investment and customer adoption time.
- Can you create variants of existing winners?
- Do seasonal ingredients offer fresh opportunities?
- Which current inventory items could expand their menu presence?
The goodbye: how to remove a dish
Avoid abrupt removals. Let dishes naturally phase out by stopping ingredient orders and allowing inventory depletion.
Customer inquiries about missing items actually validate your analysis - only dishes worth missing deserve to be remembered.
How do you calculate whether a dish can go? (step by step)
Gather 3 months of sales data
Count how many of each dish you sold over the past 3 months. Also check the same period last year for seasonal effects. Note the selling price and ingredient costs per dish.
Calculate profit contribution per dish
Subtract the ingredient costs from each selling price (excl. VAT). Multiply this by the number of sales. This gives you the total profit contribution per dish over 3 months.
Rank and determine the threshold
Sort all dishes by profit contribution. Dishes that make up less than 2% of your total dish sales AND score below average on profit contribution are candidates for removal.
✨ Pro tip
Track your bottom 4 performers monthly using 90-day rolling averages. If they collectively generate under 8% of total dish revenue, you can safely eliminate 2 without impacting overall sales.

Frequently asked questions
How long should I wait before removing a new dish?
Give new additions at least 3 months to find their audience. Check 6-week trends to spot upward momentum. Customer discovery takes time, but clear patterns emerge quickly.
What if a dish sells little but generates high profit per portion?
You've got a 'puzzle dish' - profitable but unpopular. Try repositioning it prominently or training staff to recommend it before cutting. Sometimes great dishes just need better marketing.
Should I account for seasons when removing dishes?
Absolutely critical. Today's slow seller might dominate next season's sales. Always review full-year data or compare identical periods from previous years before making permanent decisions.
What if regular customers ask for a removed dish?
That's validation you made a thoughtful choice - only memorable dishes get missed. Consider bringing it back as an occasional special without permanent menu commitment.
