Most restaurant owners panic when facing a 20% ingredient price spike, but the real damage often comes from hasty reactions rather than the increase itself. Your main ingredient going up doesn't mean your entire dish cost jumps 20%. Calculate first, then choose your strategy wisely.
First, calculate the impact on your food cost
Before you make any moves, figure out what this price bump actually costs you. A 20% increase on one ingredient rarely translates to 20% higher food cost for the whole dish.
? Example:
Your pasta carbonara breaks down like this:
- Pasta: €0.80
- Bacon: €2.40 (jumps to €2.88)
- Cream: €0.60
- Cheese: €1.20
- Other: €0.50
Original cost: €5.50
New cost: €5.98 (+8.7%)
See that? Bacon shoots up 20%, but your total food cost only climbs 8.7%. That's crucial intel for your next move.
You've got 4 options
Each path has trade-offs. Your choice depends on the dish, your customers, and your margins.
Option 1: Bump the menu price
- Pro: Margin stays intact
- Pro: Quick fix
- Con: Customers spot it right away
- Con: Risk losing sales volume
Option 2: Shrink the portion
- Pro: Menu price stays put
- Pro: Less obvious to diners
- Con: Can backfire if customers notice
- Con: Doesn't work for steaks or whole fish
Option 3: Swap the ingredient
- Pro: Might even cut costs
- Pro: Chance to upgrade the dish
- Con: Recipe changes completely
- Con: Requires testing and staff training
Option 4: Eat the cost
- Pro: Zero customer disruption
- Pro: No sales risk
- Con: Profit per plate drops
- Con: Unsustainable if costs keep climbing
Which option fits your situation?
From years of working in professional kitchens, I've seen the same patterns play out. Here's what typically works:
? Decision framework:
Top-selling dish? Avoid price hikes. Try portion tweaks or ingredient swaps instead.
High-end dish with fat margins? Price increases usually stick. Your clientele expects quality over bargains.
Already thin margins? You can't absorb this hit. Act fast or watch profits vanish.
Run the numbers on each option
Don't guess. Calculate what each choice means for your bottom line:
? Real scenario:
You move 80 portions weekly at €18.50 each.
Option 1 - Price jumps to €19.50:
- Same margin, but maybe 10% fewer orders
- 72 portions × €19.50 = €1,404 revenue (-€76/week)
Option 4 - Absorb the increase:
- 80 portions × €18.50 = €1,480 revenue
- But €0.48 less profit per dish = €38.40/week loss
⚠️ Reality check:
Always project annual impact. That €38.40 weekly loss becomes €2,000 yearly. Small leaks sink ships.
Loop in your team
Your staff can make or break these changes. Get them on board:
- Break down how price increases squeeze margins
- Brainstorm alternative ingredients together
- Coach them on explaining changes to customers
- Track results as a team
Build defenses for next time
Smart operators prepare for volatility:
- Quiz suppliers about upcoming price trends
- Pad your food cost targets (aim for 30% instead of 35%)
- Review cost prices on bestsellers monthly
- Keep backup ingredients researched and ready
Food cost calculators help you spot price impacts instantly across your entire menu, no manual math required.

How do you handle a 20% price increase? (step by step)
Calculate the actual impact
Calculate how much your food cost rises for the entire dish. A 20% increase on one ingredient often means 5-10% higher total cost price. Use the formula: new cost price divided by old cost price minus 1.
Compare your 4 options
Calculate for each option what it costs or brings in: raise price, reduce portion, replace ingredient, or accept lower margin. Look at impact on both revenue and profit per week.
Test and implement your choice
Start with your best option and monitor the results. With a new ingredient: test first with a small part of your inventory. With a price increase: watch sales figures in the first few weeks.
✨ Pro tip
Contact your backup suppliers within 24 hours and negotiate a 3-month price lock if possible. This buys you time to implement menu changes without rushing decisions that could hurt your reputation.
