Which mobile donut catering expenses are fixed, and which move with sales?

Cost classification

Break-even only works if each expense behaves the way the model says it does. Treat rent as fixed, ingredients and card fees as variable, and capacity-linked labor or maintenance as semi-fixed.

Expense	Cost	Break-Even Treatment	Common Mistake
Rent	Fixed	Include $5,000 per month in fixed overhead, then divide by contribution margin.	Spreading rent per event too early and hiding the monthly hurdle.
Utilities	Semi-variable	Keep the $1,200 monthly plan in overhead, but expect usage to rise with more event prep.	Treating all utility spend as fixed even when production hours grow.
Insurance	Fixed	Include $400 per month even in slow months because coverage does not stop when bookings dip.	Leaving it out of break-even because it is not tied to each order.
POS & Software Subscriptions	Fixed	Include $300 per month as operating overhead separate from payment processing.	Burying subscriptions inside credit card fees and double-counting payment costs.
Equipment Maintenance	Semi-fixed	Model $500 per month as a base, then step it up when event volume strains equipment.	Assuming maintenance stays flat after capacity and usage increase.
Food Ingredients	Variable	Apply 11.8% of first-year revenue, declining to 9.8% by the fifth year in the model.	Using a flat dollar amount instead of tying ingredients to sales volume.
Credit Card Fees	Variable	Apply 2.4% of first-year revenue, declining to 1.9% by the fifth year in the model.	Classifying processing fees as fixed software spend.
Wages	Semi-fixed	Start with $24,167 per month in first-year payroll; treat salaried roles as fixed and event staffing as step-based.	Modeling all labor as variable when core staff must be paid before bookings scale.

How does break-even shift from lean to base to full-volume catering?

Scenario table

As cover counts and average order value rise from lean to full volume, revenue climbs faster than variable costs, but payroll also steps up, so break-even revenue moves from about $41.4k to $53.6k.

Planning view only: these scenario figures are model assumptions, not guaranteed event results.

Scenario	Monthly Revenue	Variable Costs	Fixed Costs	CM Ratio	Operating Profit	Break-Even Signal
Lean Year 1 mix	$119,508	$23,304	$33,317	80.5%	$62,887	Above break-even, but the cushion is thinner.
Base Year 3 mix	$194,850	$34,488	$38,317	82.3%	$122,045	This is the planning case, and the cushion is solid.
Full Year 5 mix	$281,277	$44,160	$45,192	84.3%	$191,925	Strong cushion and less break-even risk.

What breaks the break-even plan for a mini donut caterer?

Stress test

The base case clears break-even with about $78.1k of cushion on $119,508 of revenue. The weak spots are a 20% revenue dip and any jump in overhead or input costs, because both cut that cushion fast.

Stress Case	Changed Assumption	Break-Even Revenue	Revenue Gap	Risk Signal
Current plan	No change from the base case.	$41,400	$78,108 cushion	Strong buffer, but fixed costs are heavy.
Revenue shortfall	Revenue falls 20% to $95,606.	$41,400	$54,219 cushion	Still viable, but the cushion shrinks fast.
Fixed-cost pressure	Fixed costs rise 10%.	$45,525	$73,983 cushion	Higher overhead trims room, not profit yet.
Margin pressure	Variable expenses rise to 245%.	$44,128	$75,380 cushion	Input pressure cuts room before sales do.
Combined pressure	Revenue falls 20% and costs rise together.	$48,540	$47,066 cushion	Loss starts near $48.5k of revenue.

What should a mini donut catering founder verify before locking in rent and equipment?

Founder checklist

Prove bookings, not just interest, before you take on fixed rent and equipment. The model only works if Saturday volume, midweek pricing, and cash reserves can carry the Month 3 break-even plan without starving launch.

1Booking Proof150 Sat

Confirm pre-booked events are real before you sign the $5,000 rent, because empty weekends make break-even slip fast.

2Weekend Capacity150 covers

Test that the team and setup can handle the Year 1 Saturday cover assumption of 150 without slowing service.

3Price Mix$35 / $50

Check that deposits and order mix hold around the midweek $35 and weekend $50 average order values, or revenue will run light.

4Fixed Load$9.15K/mo

Make sure the monthly fixed bill can be carried before launch, since rent, utilities, insurance, software, maintenance, cleaning, security, and marketing stack up fast.

5Staffing Load$290K/yr

Keep staffing tight because Year 1 wages total $290,000 annually and the model can get bloated before demand catches up.

6Cash & Capex$802K

Hold the Month 2 cash floor at $802,000 before buying the $35,000 oven, $25,000 kitchen equipment, $8,000 POS hardware, $5,000 smallwares, and the $10,000 initial stock.
