Which expenses are fixed, variable, semi-variable, or semi-fixed in a pool maintenance break-even model?

Cost classification

Break-even only works if each expense follows the right behavior. Treat chemicals, parts, fuel, and card fees as revenue-linked, while rent and core overhead stay fixed within the monthly planning range.

Expense	Cost	Break-Even Treatment	Common Mistake
Pool Chemicals and Testing Supplies	Variable	Model at 12.0% of revenue in the first year.	Adding initial chemical inventory as a normal monthly expense.
Equipment Parts and Replacement Items	Variable	Model at 8.0% of revenue in the first year.	Treating parts as fixed even when service volume rises.
Vehicle Fuel and Maintenance	Variable	Model at 8.0% of revenue in the first year.	Counting service vehicle purchases inside monthly break-even.
Credit Card Processing Fees	Variable	Model at 2.5% of revenue across the forecast.	Using a flat monthly estimate instead of payment volume.
Office Rent	Fixed	Use $4,500 per month from Month 1 through Month 60.	Scaling rent with revenue before a space change is planned.
Insurance Premiums	Fixed	Use $2,800 per month across the operating forecast.	Leaving insurance out because it is not tied to jobs.
Utilities and Communications	Semi-variable	Start with the $800 monthly baseline, then review usage as routes expand.	Assuming every dollar stays fixed as field activity grows.
Pool Technician Wages	Semi-fixed	Add labor in hiring steps as route volume requires more capacity.	Modeling technician payroll as a smooth percentage of sales.

How do lean, base, and full pool route setups change break-even?

Scenario table

The first-year mix gives a $168 weighted monthly fee. Variable costs take 30.5% of revenue, so contribution is 69.5%. With about $54.2k of fixed load, the base route is essentially break-even, and Month 9 matches the model.

Planning assumptions only; route mix and step hires can move break-even.

Scenario	Monthly Revenue	Variable Costs	Fixed Costs	CM Ratio	Operating Profit	Break-Even Signal
Lean route, 463 accounts	$77,784	$23,723	$54,177	69.5%	-$116	Below 464 accounts, the route stays loss-making.
Base route, 464 accounts	$77,952	$23,775	$54,177	69.5%	$0	At about 464 accounts, the route is at break-even and Month 9 matches the model.
Full route, 465 accounts	$78,120	$23,827	$54,177	69.5%	$116	Above 464 accounts, each extra account adds about $117 of monthly contribution.

What breaks the break-even plan for a pool maintenance business?

Stress test

Break-even is tight in the first year because Month 8 still needs $528K of cash, Month 9 is the break-even point, and Year 1 EBITDA is -$151K. A small revenue miss, higher route costs, or 1 point of margin drag pushes the target up fast.

Stress Case	Changed Assumption	Break-Even Revenue	Revenue Gap	Risk Signal
Current plan	No change.	$779,000	$0 gap	Month 9 is the base break-even point.
Revenue shortfall	One recurring account drops out before the route is full.	$981,000	$202,000 gap	A small miss turns into a large annual hole.
Fixed-cost pressure	Fixed monthly overhead rises by $1,000.	$793,000	$14,000 gap	Rent, insurance, and payroll creep move break-even fast.
Margin pressure	Variable costs take 1 more point of revenue.	$791,000	$12,000 gap	Chemicals, parts, fuel, and card fees squeeze margin.
Combined pressure	One account slips, overhead rises $1,000 monthly, and margin falls 1 point.	$1,007,000	$228,000 gap	This is the harshest case before the route is full.

What should a pool maintenance founder verify before buying vehicles and hiring the first crew?

Founder checklist

Before you buy vehicles and add payroll, confirm the route book can support the $168 weighted monthly fee, the 69.5% contribution margin, and the Month 8 cash peak. If account density is thin, break-even slips fast because fleet, insurance, and labor start before revenue matures.

1Route Mix$168/mo

Map service areas before you hire technicians and verify the package mix really lands at a $168 weighted monthly fee, because thin routes make the first crew uneconomic.

2Contribution69.5% CM

Validate that chemicals, parts, fuel, and card fees stay at 30.5% of revenue, which leaves 69.5% to cover payroll, rent, and growth.

3Fixed Load$11.2K/mo

Keep the fixed run rate at $11.2K a month and fund the first cash outlay of $90K for vehicles, $25K for tools, and $18K for chemicals before you lock overhead.

4Crew Ramp3 tech FTE

Start with the Year 1 staffing plan of 3 technician FTEs, 1 operations manager, 1 customer service rep, and 0.5 marketing FTE so payroll grows only when account density does.

5Launch Demand$120K / $150 CAC

Pressure-test the Year 1 marketing budget of $120K against a $150 CAC, because each new account has to arrive fast enough to bridge the gap to Month 9 break-even.

6Cash Buffer$528K

Hold cash for the $528K low point in Month 8, or the business can run out of room before the route book and collections stabilize.
