Staff Cost per Event for Caterers

Why staff cost per event is a critical metric

A caterer sells events, not hours. Each event has a price billed to the client and a cost price. The difference is your margin. And in that cost price, staff weighs heavily.

A 200-guest wedding with 26 temporary staff averaging 10 hours means 260 hours of work. At an average loaded hourly cost of 20–25 euros, the staff bill reaches 5,200 to 6,500 euros for a single event. If your quote budgeted 4,500 euros for staff, you have a profitability problem.

Without precise per-event tracking, you are operating blind. You quote by feel, underestimate costs, and discover at month-end that your margin has evaporated.

Components of staff cost

Temporary staff cost

The cost of a temporary worker includes:

• Gross wage: according to the Joint Committee 302 (Belgian hospitality collective agreement) scale and professional category (waiter, cook, head waiter)
• Employer contributions: approximately 25–30% of gross wage for a standard temporary worker, much less for a student worker (5.42%)
• Supplements: Sunday (+2 euros/h), night (+1.24 euros/h), public holidays (doubled)
• Holiday pay: included in the calculation for regular temporary workers
• Workplace accident insurance: premium proportional to the wage bill

The total loaded hourly cost of a temporary waiter (including contributions, excluding supplements) ranges from 18 to 24 euros depending on the scale. An experienced head waiter costs 25 to 30 euros fully loaded.

Fixed staff cost

Your head chef, permanent cooks and logistics manager contribute to every event. Their cost must be allocated across events. If your chef works 160 hours a month and you run 12 events, each event carries approximately 13 hours of chef cost.

This allocation is often overlooked. Caterers calculate temporary staff cost per event but forget to charge fixed staff cost. Result: the reported margin is overstated.

Indirect costs

Other costs are linked to staff but not directly to the service:

• Recruitment and training time for temporary workers
• Administrative management (contracts, Dimona (Belgian employee registration system) declarations, pay slips)
• Transport of staff to the event venue (if covered by employer)
• Staff meals during the event
• Work clothing provided by the employer

Calculating cost before the event: the quote

Estimating hours needed

The starting point of the quote is estimating staff hours. For each role, estimate:

• Number of people needed (based on ratios for the event type)
• Duration of the service (not just service, but setup and breakdown too)
• Total hours = people x duration

Example for a 150-guest wedding, plated service:

• 13 waiters x 9h (16:00–01:00) = 117 hours
• 1 head waiter x 10h (15:00–01:00) = 10 hours
• 3 cooks x 12h (08:00–20:00) = 36 hours
• 1 chef x 14h (07:00–21:00) = 14 hours
• 2 dishwashers x 8h (17:00–01:00) = 16 hours
• 2 bartenders x 6h (21:00–03:00) = 12 hours
• 2 drivers x 8h (12:00–20:00) = 16 hours

Estimated total: 221 hours.

Applying hourly costs

Multiply hours by the loaded hourly cost for each profile:

• Waiters: 117h x 20 euros = 2,340 euros
• Head waiter: 10h x 28 euros = 280 euros
• Cooks: 36h x 22 euros = 792 euros
• Chef: 14h x 30 euros (allocated fixed staff) = 420 euros
• Dishwashers: 16h x 18 euros = 288 euros
• Bartenders: 12h x 22 euros = 264 euros
• Drivers: 16h x 20 euros = 320 euros

Estimated total: 4,704 euros.

Adding supplements

If the event is on a Saturday, no specific supplement applies. If it is on a Sunday, add 2 euros per hour per person. If service runs past midnight, add the night supplement for hours between midnight and 5am.

For a Saturday wedding with bar service until 3am: 2 bartenders + 1 dishwasher + 1 manager = 4 people x 3 night hours x 1.24 euros = 14.88 euros in night supplements. The amount is modest, but for a Sunday event with 20 temporary workers over 8 hours, the Sunday supplement reaches 320 euros.

The safety margin

Add 10–15% to the estimated cost to cover contingencies: unplanned overtime, last-minute reinforcements, breakdown running longer than expected. A quote without a margin is a quote that loses money on the first unexpected issue.

Measuring actual cost after the event

Actual vs. estimated hours

On-site time tracking records actual hours for each person. After the event, compare actual to estimated:

• Total actual hours vs. estimated hours
• Variance by role (did breakdown take longer? Did waiters finish earlier?)
• Total actual cost vs. quote budget

Shyfter automatically calculates the actual cost by aggregating logged hours, applicable scales and supplements. You get the real staff cost for the event without manual calculation.

Variance analysis

A variance between estimated and actual cost always has a cause:

• Hour underestimation: setup or breakdown took longer than expected
• Additional temporary workers: a last-minute reinforcement not included in the quote
• Overtime: event ran long, guests wouldn't leave
• Unanticipated supplements: an event that spilled into Sunday or a public holiday
• Different profile mix: more experienced (and more expensive) waiters than planned

Document each variance. Over time, your estimates improve and your quotes become more accurate.

Profitability per event

Margin calculation

The margin on an event is calculated as:

Price billed to client - (raw material cost + staff cost + logistics cost + indirect costs) = net margin of the event.

Staff cost typically represents 30–40% of the price billed. If this ratio exceeds 45%, your event is underpriced or your staff management is inefficient.

Profitability by event type

Not all event types have the same profitability. Analyse your data by category:

• Weddings: high hour volume, but comfortable margin on premium menus
• Corporate cocktails: fewer hours, lower unit margin, but potentially high volume
• Buffets: favourable staff-to-guest ratio, but often lower sale price
• Prestige events: high-end staff (more expensive), but high sale price

Shyfter lets you compare profitability by event type over a given period. You identify your most profitable events and steer your business development accordingly.

The break-even point

For each event type, define a break-even point: the maximum staff cost as a percentage of the price billed. If a 150-guest wedding exceeds 40% staff cost, analyse why: too many temporary workers? Poorly estimated hours? Unanticipated supplements?

Optimising staff cost

Student worker / temporary staff mix

Student workers have lower social security contributions. A 50% student workers / 50% standard temporary workers mix reduces your average cost by 15–20% compared to a 100% standard temporary worker mix. Adjust this ratio based on the level of service required.

Estimation accuracy

The more accurate your time estimates, the fewer surprises. Use data from past events as a reference. A 150-guest wedding with plated service — you have done it before. How many actual hours? That is your best forecasting tool.

Reducing unproductive hours

Analyse setup time, waiting time between services and breakdown time. Are there savings possible? Better-prepared setup (detailed loading lists, installation plan) reduces on-site time. Organised breakdown (each team knows what to do) speeds up the end of the day.

Optimising simultaneous events

When you have multiple events on the same day, fixed staff costs are better spread. A chef supervising production for 3 events costs the same salary as for 1. Shared logistics (a single depot, pooled vehicles) also reduces unit costs.

Financial reporting

Per-event summary

After each event, generate a financial summary:

• Total hours worked, broken down by role
• Total gross wage cost
• Social security contributions
• Supplements applied
• Total loaded cost
• Variance vs. quote budget
• Staff cost / price billed ratio

Monthly dashboard

Aggregate data from all events in the month:

• Total monthly staff cost
• Average cost per event
• Cost-to-revenue ratio
• Trend vs. previous months
• Breakdown: student workers vs. temporary staff vs. fixed staff

Seasonal analysis

Compare seasons. Does staff cost per event increase in peak season (temporary workers scarcer, rates up)? Is the margin better in June or September? These analyses guide your commercial and pricing strategy for the following season.

Shyfter aggregates all this data automatically from logged hours and configured scales. You get reporting without re-entry, fed by field data.

FAQ

What percentage of a catering event price does staff cost represent?

On average, staff cost represents 30–40% of the price billed to the client. This ratio varies by event type: a buffet (less staff per guest) sits around 25–30%, while high-end plated service can reach 40–45%. Beyond 45%, profitability is at risk and you need to review either the price or the organisation.

How do you factor supplements into a catering quote?

Identify the event day (Saturday = no supplement, Sunday = +2 euros/h, public holiday = doubled) and the hours (after midnight = night supplement). Calculate the total surcharge and add it to the staff line in the quote. For a Sunday event with 20 temporary workers over 8 hours, the Sunday supplement is 320 euros. Don't forget it: it is lost margin.

How do you track staff cost in real time during an event?

Mobile time tracking via Shyfter records each person's hours in real time. The system automatically applies scales and supplements. You can view the cumulative staff cost at any point during the event. If the cost is approaching the budget, you see it before the event ends, not two weeks later on the pay slip.
