As a restaurant owner, you've likely received emails or calls from corporate catering marketplaces promising to flood your kitchen with new orders. The pitch sounds enticing: access to thousands of hungry office workers, streamlined ordering systems, and a steady stream of revenue you didn't have to chase down yourself.
But here's the question that should keep you up at night before signing any agreement: Do you actually know what your catering profit margin is?
Not your dine-in margin. Not your takeout margin. Your catering-specific profit margin—the number that accounts for every unique cost associated with preparing, packaging, transporting, and servicing large orders for corporate clients.
If you can't answer that question with confidence, you're not alone. Most restaurant owners operate on assumptions and averages, which can lead to devastating financial surprises when marketplace commission fees start eating into margins that were thinner than expected.
This guide will walk you through exactly how to calculate your true catering profit margin so you can make an informed, profitable decision about joining any corporate catering marketplace.
Why Catering Margins Are Different From Your Regular Restaurant Business
Before we dive into calculations, let's address a common misconception: many restaurant owners assume their catering margins mirror their dine-in or takeout margins. This assumption can cost you thousands of dollars.
The Hidden Cost Differences in Corporate Catering
Workplace food service operates on an entirely different cost structure than your regular restaurant operations:
Higher packaging costs: A $15 entrée served on a reusable plate costs you maybe $0.10 in dishwashing. That same entrée packaged for office catering might require $1.50-$3.00 in containers, utensils, napkins, and serving equipment.
Transportation expenses: Delivering to office buildings requires vehicles, fuel, parking fees, and driver time—costs that don't exist for dine-in customers.
Labor intensity: Corporate lunch catering often requires specialized prep during your slowest hours, plus delivery and setup personnel who may not generate other revenue.
Minimum order requirements: Unlike a $50 table that turns over in 45 minutes, you might spend 2-3 hours preparing a $200 corporate order.
Equipment investments: Catering warmers, insulated bags, serving platters, and delivery containers represent capital expenses unique to this revenue stream.
Step-by-Step: Calculating Your True Catering Profit Margin
Now let's get into the actual math. Grab your calculator, pull up your POS data, and let's work through this together.
Step 1: Determine Your Catering-Specific Food Cost Percentage
Start with your raw ingredient costs, but adjust for catering realities:
Standard Food Cost Calculation: (Total Food Cost ÷ Total Food Revenue) × 100 = Food Cost Percentage
However, for corporate catering, you need to factor in:
- Overproduction buffers: Most caterers prepare 5-10% extra to ensure adequate portions. This safety margin directly impacts your food costs.
- Presentation additions: Garnishes, serving portions, and display elements that wouldn't be necessary for plated service.
- Waste from delivery delays: Food quality degradation that leads to complaints, refunds, or reputation damage.
Example calculation: If your standard food cost is 28%, your catering food cost might realistically be 31-35% once you account for these factors.
Step 2: Calculate Your Catering-Specific Packaging Costs
This is where many restaurant owners dramatically underestimate expenses. Track every item for a typical office catering order:
| Item | Cost Per Unit | Quantity Needed | Total | |------|---------------|-----------------|-------| | Entrée containers | $0.45 | 25 | $11.25 | | Utensil sets | $0.35 | 25 | $8.75 | | Napkins | $0.05 | 50 | $2.50 | | Serving utensils | $0.75 | 6 | $4.50 | | Catering bags | $1.50 | 3 | $4.50 | | Labels/branding | $0.15 | 25 | $3.75 | | Total Packaging | | | $35.25 |
For a $400 catering order, that's 8.8% of revenue going to packaging alone—a cost that doesn't exist in your dine-in model.
Step 3: Calculate True Labor Costs for Catering
This calculation requires honest assessment of time invested:
Prep time: Hours spent preparing catering orders (often during slow periods when staff is already clocked in, but could be doing other productive work or could be sent home)
Assembly time: Packaging, labeling, and organizing orders
Delivery time: Round-trip transportation plus setup time
Administrative time: Order taking, confirmation calls, dietary accommodation management
Example for a 25-person corporate lunch order:
- Prep time: 1.5 hours × $15/hour = $22.50
- Assembly: 0.5 hours × $15/hour = $7.50
- Delivery/setup: 1 hour × $18/hour = $18.00
- Administration: 0.25 hours × $20/hour = $5.00
- Total labor: $53.00 on a $400 order = 13.25%
Step 4: Account for Delivery and Transportation Costs
Workplace food delivery isn't free, even if you own your vehicle:
- Fuel costs: Calculate actual miles and current fuel prices
- Vehicle wear: IRS standard mileage rate is $0.67/mile (2024)—this accounts for depreciation, insurance, and maintenance
- Parking fees: Downtown office buildings often require paid parking
- Hot/cold bag depreciation: Quality insulated bags cost $50-150 and need replacement
Example for a 10-mile round-trip delivery:
- Mileage: 10 miles × $0.67 = $6.70
- Parking: $8.00
- Equipment wear: $2.00
- Total delivery cost: $16.70 = 4.2% of a $400 order
Step 5: Factor in Overhead Allocation
Your restaurant has fixed costs that catering operations should share:
- Rent and utilities
- Insurance (you may need additional coverage for catering/delivery)
- POS systems and technology
- Marketing and advertising
- Administrative expenses
A reasonable overhead allocation for catering is typically 10-15% of catering revenue, depending on how much of your fixed costs the catering arm utilizes.
The Complete Catering Profit Margin Formula
Now let's put it all together:
Catering Profit Margin = Revenue - (Food Cost + Packaging + Labor + Delivery + Overhead + Marketplace Commission)
Real-World Scenario: Before and After Marketplace Fees
Let's run the numbers on a typical $500 corporate catering order:
Your Costs:
- Food (32%): $160
- Packaging (8%): $40
- Labor (13%): $65
- Delivery (4%): $20
- Overhead (12%): $60
- Total Costs: $345
Your Profit Before Marketplace: $155 (31% margin)
Now, add a typical 15-20% marketplace commission:
With 15% commission ($75): Profit = $80 (16% margin) With 20% commission ($100): Profit = $55 (11% margin)
This is the reality check most restaurant owners need. That "free marketing" from a corporate catering marketplace cuts your profit margin roughly in half.
When Marketplace Economics Still Make Sense
Before you dismiss marketplace partnerships entirely, consider scenarios where the math can work in your favor:
Utilizing Excess Capacity
If your kitchen sits idle from 9-11 AM, catering orders during these hours use capacity you're already paying for. Your overhead allocation for these orders approaches zero, improving margins significantly.
Building Corporate Accounts for Direct Ordering
Smart restaurant owners use marketplaces as a customer acquisition channel. Once you've impressed a corporate client, there's often opportunity to transition them to direct ordering—eliminating the commission while retaining the relationship.
Scaling Without Marketing Investment
Customer acquisition costs for corporate catering clients can be steep. If your alternative is spending 20% of revenue on sales staff and marketing anyway, the marketplace commission is essentially a performance-based marketing expense.
Volume Negotiations
Established catering operations with proven track records can often negotiate reduced commission rates. Starting at 20% doesn't mean staying at 20%.
Questions to Ask Before Joining Any Catering Marketplace
Armed with your profit margin calculations, you're now prepared to have informed conversations with marketplace representatives. Ask these questions:
-
What is your commission structure? Is it flat-rate or tiered based on volume?
-
Are there additional fees? Payment processing, delivery coordination, promotional programs?
-
What's the average order value on your platform? Higher AOV means more dollars despite the percentage cut.
-
What marketing support do you provide? Are you featured equally, or do promoted restaurants get preference?
-
What are the customer service expectations? Who handles complaints, refunds, and disputes?
-
Can I maintain direct relationships with clients? Some contracts prohibit soliciting marketplace customers for direct ordering.
-
What's the contract term and exit process? Flexibility matters if the economics don't work out.
Creating Your Catering Profitability Dashboard
Successful restaurant owners don't calculate profit margins once—they track them continuously. Build a simple tracking system that monitors:
- Average catering order value
- Food cost percentage per order
- Packaging cost per order
- Labor hours per order
- Delivery cost per order
- Commission/fee per order
- Net profit per order
- Net profit margin percentage
Review these metrics weekly during your first few months with any new marketplace partnership. If margins consistently fall below acceptable thresholds, you have data to support negotiation—or exit.
Setting Your Minimum Acceptable Margin
What margin do you need to make corporate catering worthwhile? There's no universal answer, but consider:
- Below 10%: Dangerous territory. One bad order, one refund request, or one unexpected expense wipes out profit.
- 10-15%: Acceptable for volume-building phases, but not sustainable long-term.
- 15-25%: Healthy range that provides cushion for operational hiccups.
- Above 25%: Excellent—you've either optimized operations exceptionally well or have pricing power to protect.
Making Your Decision With Confidence
You now have the framework to calculate exactly what your catering profit margin is—and what it will be after marketplace commissions. This positions you to make strategic decisions rather than hopeful guesses.
Remember: joining a corporate catering marketplace isn't inherently good or bad for your restaurant. It's a business decision that deserves business-level analysis. With accurate profit margin calculations, you can negotiate from strength, set appropriate menu prices, and structure operations that remain profitable even after platform fees.
