Which karate dojo expense categories are fixed, variable, or step up as enrollment grows?

Cost classification

A break-even model only works if fixed monthly dojo expenses stay fixed and sales-linked items flex with revenue. Treat rent and core payroll as baseline load; treat supplies, marketing, and card fees as margin drag.

Expense	Cost	Break-Even Treatment	Common Mistake
Dojo Facility Rent	Fixed	Use $4,500 per month as baseline overhead before any student revenue.	Don’t tie rent to student count.
Utilities and Internet	Fixed	Use $650 per month in this model for the relevant planning range.	Don’t inflate it per student without evidence.
Liability Insurance	Fixed	Use $300 per month as a required recurring operating expense.	Don’t bury it in admin.
Cleaning Services	Fixed	Use $400 per month to keep the training space ready for classes.	Don’t skip hygiene standards.
Uniforms and Gear Inventory	Variable	Apply 6% of first-year revenue because supplies move with sales volume.	Don’t count inventory sales without matching supplies.
Digital Marketing and Lead Gen	Variable	Apply 8% of first-year revenue during the enrollment ramp.	Don’t stop spend during enrollment ramp.
Payment Processing Fees	Variable	Apply 3% of revenue for card and payment collection fees.	Don’t forget card fees.
Assistant Instructor	Semi-fixed	Model payroll in staffing steps: 1.0 FTE in first year and 1.5 FTE in second year.	Don’t add class times without payroll.

How does break-even change from a lean dojo launch to a full class schedule?

Scenario table

Lean uses Year 1 assumptions, so tuition has less room to cover overhead. Base and full add enrollment and price, while belt testing fees stay upside, not the main break-even driver.

Planning view only; these scenario figures use model assumptions and are not guaranteed enrollment or profit results.

Scenario	Monthly Revenue	Variable Costs	Fixed Costs	CM Ratio	Operating Profit	Break-Even Signal
Lean dojo launch	$91K	$17K	$16K	81%	$58K	Positive, but the cushion is thin if occupancy slips.
Base staffed dojo	$242K	$41K	$19K	83%	$182K	Tuition covers overhead more comfortably, so break-even risk drops.
Full mature dojo	$460K	$71K	$20K	84.5%	$369K	Strongest cushion; recurring tuition covers fixed costs well before belt fees.

What breaks the break-even plan for a karate dojo?

Stress test

A 20% revenue drop or a 10% cost bump still leaves this dojo above break-even, but the cushion narrows fast if occupancy slips below 45% or lead costs stay above 8% of revenue. The biggest risk is adding staff before enrollment catches up.

Stress Case	Changed Assumption	Break-Even Revenue	Revenue Gap	Risk Signal
Current plan	No change; revenue stays near $913K and variable expenses stay at 19%.	$197K	$716K cushion	Break-even sits far below plan revenue.
Revenue shortfall	Revenue falls 20% to about $731K while costs stay the same.	$197K	$534K cushion	Still safe, but low occupancy would be the first warning.
Fixed-cost pressure	Fixed costs rise 10% from about $159K to about $175K.	$216K	$697K cushion	Higher rent or extra staff raise the floor, not the alarm.
Margin pressure	Variable expenses rise to 24%, cutting contribution margin to 76%.	$209K	$704K cushion	Lead costs above 8% would start squeezing the cushion.
Combined pressure	Revenue drops 20%, fixed costs rise 10%, and variable expenses rise to 24%.	$230K	$501K cushion	Still above break-even, but adding instructors too early is risky.

What should you prove before you sign the dojo lease and add staff?

Founder checklist

Test the student mix, pricing tiers, and class fill before you lock the lease. If the opening plan can’t hold 40 little ninjas, 80 youth students, and 30 adults at the modeled prices, break-even gets shaky fast.

1Demand Mix40 / 80 / 30

Verify the opening student mix at $125, $160, and $175 monthly before you commit to the lease, because the whole break-even path depends on those enrollments landing.

2Fixed Overhead$6.25K/mo

Check that rent, utilities, insurance, software, cleaning, and accounting stay near this base load, since fixed costs set the floor you have to cover every month.

3Margin Math81% CM

After 6% gear cost, 2% belt supplies, 8% digital marketing, and 3% payment fees, the model keeps about 81 cents of each revenue dollar before wages and rent.

4Capacity Ramp22 days / 45%

Make sure the class schedule can absorb 22 billable days a month at 45% occupancy in Year 1, and hold assistant expansion until attendance supports the extra payroll.

5Cash Cushion$889K

Keep this reserve ready because the model’s low point hits in Month 1, so launch costs and payroll land before the membership base fully settles.

6Launch TrackingTrials, joins, churn

Set up waivers, recurring billing, student management software, and payment processing before launch month so you can track leads, trial starts, joins, and drop-off.
