What happens when your expenses climb while your income plummets? You're stuck paying overtime wages to staff while fewer customers walk through your door. This double hit demands immediate action to save your restaurant's financial health.
Start by diagnosing the root problem
Rising prime cost stems from two main culprits: excessive labor expenses or inflated food costs. Declining revenue makes this worse since you're spreading fixed expenses across smaller sales figures.
💡 Example:
Restaurant with 20% food cost and 35% labor cost = 55% prime cost at normal revenue of €50,000/month:
- Food cost: €10,000
- Labor cost: €17,500 (including €2,500 overtime)
- Prime cost: €27,500
At 20% lower revenue (€40,000) but same costs:
- Prime cost: €27,500 / €40,000 = 68.8%
That's unsustainable. Anything above 60% prime cost spells trouble.
Tackle labor costs head-on
Overtime kills your margins faster than almost anything else. Each overtime euro costs you 1.5 to 2 euros because of wage premiums.
- Cut non-essential overtime: Deep cleaning, prep work, and paperwork can wait
- Release staff early: Fewer customers means you need fewer hands on deck
- Redesign schedules: Match staffing levels to realistic customer projections
- Deploy temporary workers wisely: Sometimes temp rates beat overtime premiums
⚠️ Important:
You can't legally send people home without pay. Plan smarter schedules based on expected busy periods instead.
Maintain food cost discipline
Revenue drops often tempt owners toward cheaper ingredients. That's typically a mistake since it hurts quality and customer loyalty.
- Attack waste first: Every discarded euro hurts twice as much now
- Enforce portion control: Stick to your recipe specifications religiously
- Analyze your menu stars: Which dishes actually drive profit?
- Shift menu focus temporarily: Highlight lower-cost, high-margin options
💡 Example of waste reduction:
At €40,000 revenue and 20% food cost you're buying €8,000 in ingredients. Cutting waste from 10% to 5%:
- Monthly savings: €8,000 × 5% = €400
- Prime cost improvement: 1 full percentage point
Drive revenue without spending money
Most revenue-boosting tactics require investment in marketing or promotions. But several free strategies can deliver quick results.
- Amplify social media: Showcase your profitable dishes more frequently
- Turn staff into promoters: Encourage them to bring friends and family
- Perfect your upselling: Appetizers, desserts, and drinks boost average tickets
- Create strategic deals: Fill slow periods with lower-margin, higher-volume offers
Consider drastic measures for severe cases
Prime costs consistently above 65% signal that minor tweaks won't suffice. You'll need to choose between aggressive revenue growth or major cost cuts - a pattern we see repeatedly in restaurant financials during tough periods.
⚠️ Important:
Prime costs above 70% usually mean you're operating at a loss. Act fast or face potential bankruptcy.
- Reduce operating hours: Close during consistently slow periods
- Simplify your menu: Fewer options mean less inventory risk and faster prep
- Implement strategic price increases: Better to serve fewer profitable customers than many unprofitable ones
- Seek professional guidance: Fresh eyes from an accountant or consultant can spot overlooked solutions
Track progress with frequent monitoring
Crisis management requires more frequent number-crunching. Weekly reviews aren't enough - you need daily visibility into your metrics.
💡 Daily monitoring checklist:
- Yesterday's sales compared to same day last week
- Actual hours worked versus scheduled hours
- Food waste and disposal costs
- Current cash position and upcoming obligations
Tools like KitchenNmbrs can automate these calculations, giving you instant visibility without manual spreadsheet work. During financial emergencies, rapid access to accurate data makes the difference between recovery and closure.
How do you tackle rising prime cost? (step by step)
Calculate your current prime cost percentage
Add your food cost and labor cost and divide by your revenue. Prime cost = (food cost + labor cost) / revenue × 100. Anything above 60% requires action.
Identify the biggest cost item
Is it overtime driving up your labor cost, or waste driving up your food cost? Focus on the biggest leak first before tackling everything at once.
Take immediate action
Stop non-essential overtime, limit waste, and send staff home early when occupancy is low. Every euro you save today helps your cashflow.
Monitor your progress daily
Check your revenue, hours worked, and waste every day. In crisis situations, weekly checks are too slow. You need to be able to adjust before it's too late.
✨ Pro tip
Monitor your prime cost every 48 hours during revenue declines, not weekly. Two days gives you enough data to spot trends while leaving time to course-correct before cash flow becomes critical.

Frequently asked questions
What prime cost percentage signals real danger?
Anything above 65% puts you in the danger zone, while 70% or higher typically means you're losing money. Most successful restaurants maintain prime costs between 55-60%.
Can I legally send employees home early when business is slow?
You cannot send scheduled employees home without paying them for their scheduled hours. However, you can adjust future schedules based on realistic sales projections and historical patterns.
Should I raise menu prices to fix high prime costs?
Price increases can help, but approach them strategically. First exhaust cost-cutting opportunities that don't compromise food quality, then implement selective price adjustments on your most popular items.
How quickly must I respond to rising prime costs?
Immediate action is essential once prime costs exceed 65%. Every day of delay compounds the problem and drains more cash from your business.
Which overtime expenses should I eliminate first?
Target non-customer-facing tasks first: administrative work, deep cleaning, inventory management, and prep work that can be rescheduled to regular hours. These cuts won't impact service quality.
What's the fastest way to reduce food waste during a revenue crisis?
Implement daily waste tracking by ingredient and dish, train staff to follow exact portion sizes, and create daily specials using ingredients nearing expiration. These steps can cut waste by 30-50% within two weeks.
