How do I calculate what percentage of my revenue should go to purchasing, staff, and other costs?

📝 KitchenNmbrs · updated 16 Mar 2026

83% of restaurants fail within the first five years, primarily due to poor cost management across purchasing, staff, and operational expenses. Most hospitality entrepreneurs can't pinpoint what percentage should go to each cost category. This knowledge gap silently erodes profits month after month.

The basics: revenue distribution in hospitality

Your total revenue gets split across four main buckets: purchasing (food & beverage), staff costs, other operational expenses, and profit. Finding the sweet spot between these categories determines if you'll thrive or barely survive.

💡 Example of standard distribution:

  • Purchasing (food cost): 30% of revenue
  • Staff costs: 35% of revenue
  • Other costs: 25% of revenue
  • Profit: 10% of revenue

Total: 100% of revenue

Calculating food cost percentage

Food cost represents the percentage of revenue spent on ingredients. Calculate this by dividing total purchasing costs by revenue (excluding VAT). The math's simple, but the implications run deep.

Formula: Food cost % = (Total purchasing / Revenue excl. VAT) × 100

💡 Example calculation:

Monthly revenue: €50,000 incl. 9% VAT = €45,872 excl. VAT

Total purchasing: €14,000

Food cost: (€14,000 / €45,872) × 100 = 30.5%

Staff costs percentage

Staff costs encompass salaries, social contributions, pension premiums, and bonuses. A pattern we see repeatedly in restaurant financials shows healthy percentages range from 30-40% of revenue, but this varies dramatically by business model.

  • Fine dining: 35-45% (more staff per guest)
  • Casual dining: 30-35%
  • Fast casual: 25-30%
  • Delivery/takeaway: 20-25% (less service staff)

⚠️ Note:

Include all staff costs, not just net wages. Social contributions can add 25-30% on top of gross salary.

Mapping out other costs

Other costs include every expense that isn't food or staff. This category gets underestimated constantly, yet can balloon to 20-30% of revenue without proper monitoring.

  • Rent and energy costs
  • Depreciation on equipment
  • Marketing and advertising
  • Insurance and administration
  • Maintenance and repairs
  • Packaging materials (for delivery)

💡 Example of other costs per month:

  • Rent: €4,000
  • Energy: €1,200
  • Marketing: €800
  • Insurance: €400
  • Other: €600

Total: €7,000 on €50,000 revenue = 14%

Determining profit margin

Profit margin equals what's left after covering all expenses. Healthy hospitality profit margins sit between 8-15%. Drop below 5% and you're walking a financial tightrope with zero cushion for unexpected hits.

Formula: Profit % = 100% - (Food cost % + Staff % + Other costs %)

Why these ratios matter

Each cost category competes for the same revenue pie. Push one too high and something else suffers. Many operators try compensating for excessive food costs by cutting staff, which destroys service quality and creates a downward spiral.

⚠️ Note:

A food cost of 40% means you need to cut other costs or raise your prices. Otherwise, you won't make any profit.

Digital tools for cost monitoring

Tracking these percentages manually consumes precious time you don't have. Digital solutions automatically calculate food cost per dish and display what percentage of revenue flows to each cost category.

How do you calculate your revenue distribution? (step by step)

1

Gather your monthly figures

Write down your total revenue, total purchasing, total staff costs, and all other expenses from last month. Convert revenue to exclude VAT by dividing by 1.09.

2

Calculate the percentages for each cost category

Divide each cost category by your revenue excluding VAT and multiply by 100. This gives you the percentage that each category takes from your revenue.

3

Compare with healthy ratios

Check if your percentages are correct: food cost 28-35%, staff 30-40%, other costs 20-30%. Is one category too high? Then you know where to take action.

✨ Pro tip

Run your cost percentage calculations every Tuesday at 9 AM using the previous week's data. This 15-minute weekly check catches cost creep before it destroys your monthly profit margins.

Frequently asked questions

What is a healthy food cost for my type of restaurant?

Most restaurants should target 28-35% food cost. Fine dining can push higher (up to 38%) due to premium ingredients, while fast casual often runs lower (25-30%). Your concept and pricing strategy determine the sweet spot.

Should I include VAT in my revenue calculation?

Never include VAT in revenue calculations. That tax money belongs to the government, not your business. Always use revenue excluding VAT for accurate cost percentages.

What if my staff costs exceed 40% of revenue?

You're likely overstaffed for your revenue level, or your menu prices are too low. Analyze scheduling efficiency first before making staff cuts. Sometimes raising prices solves the problem without layoffs.

How often should I monitor these cost percentages?

Weekly monitoring catches problems early, monthly is the bare minimum. Daily tracking during busy seasons or menu changes prevents small issues from becoming major losses.

What if I have zero profit after covering all costs?

Your costs are too high or prices too low - likely both. Start with food cost analysis since it's easiest to control quickly. If food cost exceeds 35%, that's your first target.

Can I adjust these ratios if my rent is unusually high?

High rent forces you to squeeze other categories harder. You might need to run 27% food cost instead of 30% to maintain profit. Location premiums require operational excellence across all cost centers.
