Which swim school expenses are fixed, and which move with lesson sales?

Cost classification

Break-even only works if fixed commitments stay separate from revenue-linked items. Treat the $417,000 in startup capex as opening cash needs, not monthly break-even expense, or the enrollment target gets overstated.

Expense	Cost	Break-Even Treatment	Common Mistake
Facility Lease $15,000	Fixed	Include the full monthly lease before contribution margin.	Spreading rent per lesson and treating it as variable.
Utilities Fixed $1,000	Fixed	Keep the base utility charge in monthly overhead.	Blending it with pool-use utilities and hiding fixed drag.
General Manager payroll $6,250	Fixed	Use $75,000 annual salary divided by 12 months.	Removing management pay until enrollment is full.
Swim Instructor payroll $10,000	Semi-fixed	Model Year 1 at 3.0 FTE, then step up with staffing.	Treating every instructor dollar as tied to one student.
Pool Chemicals 3%	Variable	Apply 3% of revenue in the first operating year.	Budgeting a flat amount while swimmer volume rises.
Instructor Supplies 2%	Variable	Apply 2% of revenue in the first operating year.	Ignoring supply use from higher class attendance.
Marketing & Advertising 8%	Semi-variable	Use 8% of revenue, then review minimum spend separately.	Cutting marketing to zero in low-enrollment months.
Utilities Variable 4%	Variable	Apply 4% of revenue for pool-use activity.	Combining usage charges with the fixed utility base.

How does break-even change across lean, base, and full swim school scenarios?

Scenario table

Lean is the launch case, base fits staffed growth, and full fits mature capacity because occupancy rises from 40% to 85% while variable costs fall from 17% to 9%. Higher margin then covers fixed payroll and overhead faster.

Planning cases only; actual break-even will move with enrollment, staffing, and pricing.

Scenario	Monthly Revenue	Variable Costs	Fixed Costs	CM Ratio	Operating Profit	Break-Even Signal
Lean launch case	$99,000	$16,830	$49,950	83%	$32,220	Above break-even, but the launch cushion is still thin.
Base staffed growth case	$194,300	$25,259	$58,700	87%	$110,341	Healthy cushion; this is the first growth case with room to scale.
Full mature-capacity case	$303,200	$27,288	$70,367	91%	$205,545	Wide cushion; mature occupancy gives strong break-even safety.

What pressure points can break this swim school’s break-even plan?

Stress test

Year 1 starts with a solid cushion: $99,000 revenue versus about $60,200 break-even. The weak spots are softer enrollment, higher payroll, and margin squeeze from discounts, utilities, or pool upkeep.

Stress Case	Changed Assumption	Break-Even Revenue	Revenue Gap	Risk Signal
Current plan	No change; revenue stays at $99,000 and variable expenses stay at 17%.	$60,200	$38,800 cushion	Healthy start, but fill rate still matters.
Revenue shortfall	Revenue drops 15% to $84,150.	$60,200	$23,950 cushion	Still profitable, but the cushion shrinks fast.
Fixed-cost increase	Fixed costs rise 10% to $54,945.	$66,200	$32,800 cushion	A lease or staffing step-up raises the bar quickly.
Margin pressure	Variable expenses rise to 22% of revenue.	$64,000	$35,000 cushion	Discounting or higher pool costs squeeze margin.
Combined pressure	Revenue drops 30%, variable expenses rise to 22%, and fixed costs rise 10%.	$70,400	$1,100 gap	The cushion almost disappears and turns into a small loss.

What should you verify before signing a swim school lease and buildout?

Founder checklist

Don’t sign the lease until the model clears $60.2K in monthly break-even revenue and you can fund the opening ramp. The check is simple: demand, staffing, and cash all need to line up before the buildout gets locked in.

1Break-even$60.2K/mo

Verify monthly lesson revenue can clear the break-even line before you commit, because this is the run rate that covers fixed overhead.

2Fixed load$49.95K/mo

Check the opening fixed load from the lease, payroll, and other fixed costs, since the site has to carry that burden from day one.

3Price mix$120 / $200 / $350

Test that group, semi-private, and private pricing holds at these monthly rates and still leaves the model’s 83% contribution margin intact.

4Demand proof650 places

Prove first-year demand for at least 650 lesson places across all three formats, and make sure the schedule can fill about 25 billable days at 40% occupancy.

5Staffing cover5 FTEs

Confirm opening coverage for 3 swim instructor FTEs, a head instructor, and a lifeguard, because thin coverage will cap class fill and hurt retention.

6Cash cushion$883K

Hold cash for the $883K minimum cash need and the $417K startup capex, then delay extra hiring if class fill lands below plan.
