Which pressure washing expenses are fixed, and which move with sales?

Cost classification

Break-even is only useful if fixed overhead stays separate from job-level expenses. Fuel, detergents, and card fees move with sales, so putting them in fixed overhead will overstate margin and make Month 15 break-even look too easy.

Expense	Cost	Break-Even Treatment	Common Mistake
Vehicle insurance	Fixed	Include $800/month in fixed overhead for the relevant planning range.	Spreading it across jobs and hiding the real monthly nut.
Business liability insurance	Fixed	Include $250/month before calculating required contribution margin.	Treating it like a job expense when it exists even with no jobs.
Software subscriptions for CRM and scheduling	Fixed	Include $150/month in baseline operating overhead.	Ignoring small recurring tools because each line feels minor.
Consumables for solutions and detergents	Variable	Subtract as a revenue-linked expense, starting at 5.0% in the first year and falling to 3.0% in Year 5.	Treating chemicals as fixed supplies instead of job-driven usage.
Fuel for service vehicles	Variable	Subtract from revenue at 4.0% in the first year, improving to 3.0% by Year 5.	Calling fuel fixed because the truck is already owned.
Payment processing fees	Variable	Deduct 2.5% of sales before measuring contribution margin.	Using gross customer payments as margin after card fees.
Subcontractor costs for overflow work	Semi-variable	Model as volume-linked overflow, rising from 0.0% in Year 1 to 4.0% in Year 5.	Assuming every added job can be handled by existing staff.
Annual marketing budget	Semi-fixed	Model the first year at $1,000/month, then step it up as the annual budget rises.	Matching marketing only to closed jobs instead of planned capacity growth.

How does break-even change in lean, base, and full pressure washing setups?

Scenario table

Lean break-even sits near $9.4k a month, the base case near $13.7k, and the full setup near $42.0k because fixed payroll and marketing rise faster than the margin cushion.

Planning assumptions only; actual break-even shifts with pricing, route density, and crew mix.

Scenario	Monthly Revenue	Variable Costs	Fixed Costs	CM Ratio	Operating Profit	Break-Even Signal
Lean owner-only test	$9,357	$1,357	$8,000	85.5%	$0	Low fixed costs keep break-even close, but there’s little cushion.
Base Year 1 team	$13,743	$1,993	$11,750	85.5%	$0	This is the core operating case, so steady bookings are the key.
Full Year 5 scale-up	$42,012	$6,512	$35,500	84.5%	$0	Higher payroll and marketing need dense, repeat jobs to protect margin.

What breaks the break-even plan for a pressure washing business?

Stress test

The break-even plan is most exposed to fewer booked jobs, a small jump in fixed overhead, and higher fuel or subcontractor costs. At the base structure, monthly break-even is about $13.7k, so even a modest slip can reopen a gap.

Stress Case	Changed Assumption	Break-Even Revenue	Revenue Gap	Risk Signal
Current plan	No change from the base model: $11,750 in monthly fixed costs and 14.5% variable costs.	$13,743	$0 gap	You’re right at the monthly break-even line.
Revenue shortfall	Booked jobs slip from 49 to 40 a month, pulling monthly revenue to about $11,300.	$13,743	$2,443 gap	Fewer booked jobs quickly drain the cushion.
Fixed-cost pressure	Add a $500 monthly loan or insurance payment.	$14,327	$584 gap	A small monthly charge moves break-even up.
Margin pressure	Variable expenses rise from 14.5% to 18.0% of revenue.	$14,329	$586 gap	Fuel and consumables eat margin faster.
Combined pressure	Booked jobs slip, variable expenses rise to 18.0%, and fixed costs add $500 a month.	$14,939	$1,196 gap	Demand, cost, and overhead shocks stack fast.

Can this pressure washing business hit break-even before you buy the truck and hire?

Founder checklist

Verify that booked demand can cover the model's break-even load before you lock in equipment or payroll. In Year 1, the business carries about $11.75K a month of fixed load, breaks even in Month 15, and pays back in 30 months.

1Demand proof49 jobs/mo

Verify booked demand can hold about 49 average jobs a month at a $282.50 blended ticket, because that is the pace the model needs to clear break-even.

2Fixed load$11.75K/mo

Confirm recurring overhead, base wages, and the Year 1 ad budget stay near $11.75K a month before you add a bigger truck, storage lease, or extra payroll.

3Contribution margin85.5% CM

Check contribution margin (CM), the cash left after variable costs, by testing quotes against the Year 1 variable stack, which totals 14.5% of revenue and leaves 85.5% for fixed costs.

4Staffing rampMonth 13

Hold the junior hire until route density can keep the first two techs busy, because the model adds a junior technician in Month 13 and the payroll step-up can sink margin if work is thin.

5Cash buffer$837K

Keep enough cash for the modeled trough, because minimum cash hits Month 2 at about $837K and payback does not arrive until 30 months.

6Launch demand$150 CAC

Confirm water supply, wastewater handling, safety gear, and payment collection work on the first route, because a $1,000 monthly Year 1 marketing budget at a $150 CAC only buys about 6 to 7 new customers.
