Cost classification

Break-even is only useful if fixed shop overhead stays separate from tuition-linked costs. Misclassify materials, marketing, or instructor capacity, and Month 1 break-even can look safer than it is.

Expense	Cost	Break-Even Treatment	Common Mistake
Workshop Facility Lease	Fixed	Use $12,000 per month as baseline overhead that must be covered before profit.	Treating rent as lower when enrollment is below plan.
Industrial Utilities	Semi-variable	Start with the modeled $3,500 per month, then watch machine-hour usage as class volume rises.	Assuming power and shop usage stay flat at higher occupancy.
CAD CAM Software Subscriptions	Fixed	Use $2,200 per month across the planning range, regardless of fill rate.	Linking software spend directly to each new student.
Equipment Maintenance Contract	Semi-fixed	Use $1,800 per month until added machines or heavier utilization force a higher contract tier.	Modeling maintenance as a smooth percent of tuition.
Insurance and Liability	Fixed	Use $1,500 per month as required operating overhead for the shop and training facility.	Dropping insurance during low-enrollment months.
Raw Materials and Stock	Variable	Apply 6% of first-year revenue because stock usage rises with student work and lab activity.	Budgeting materials as one flat monthly supply amount.
Student Recruitment Marketing	Variable	Apply 8% of first-year revenue to reflect spend tied to filling seats.	Counting all marketing as fixed overhead.
Lead CNC Instructor Payroll	Semi-fixed	Model capacity in staffing steps: 1.0 FTE in the first year and 2.0 FTE in the second year.	Adding instructor payroll one student at a time.

How does break-even change from a lean first year to a full third year in this machinist training program?

Scenario table

As occupancy climbs from 55% to 85%, revenue rises faster than the cost base, so fixed shop and payroll costs get absorbed more cleanly. The base case is the pivot point; after that, the program has a much wider cushion.

Planning figures only. They are modeled assumptions, not guarantees, and they do not include capex or cash runway.

Scenario	Monthly Revenue	Variable Costs	Fixed Costs	CM Ratio	Operating Profit	Break-Even Signal
Lean year 1 case	$130.1k	$26.0k	$56.9k	80%	$47.2k	Above break-even, but the cushion is still thin.
Base year 2 case	$274.3k	$49.4k	$66.5k	82%	$158.5k	Fixed costs are covered with room to grow.
Full year 3 case	$558.0k	$89.3k	$81.8k	84%	$386.9k	Well above break-even, so overhead is absorbed comfortably.

What breaks the break-even plan for this machinist training school?

Stress test

The base plan clears break-even, but the cushion shrinks fast if enrollment slips or shop costs rise. A 20% revenue dip or a 10% fixed-cost jump matters, and the combined hit still clears break-even by only about $20.6k.

Stress Case	Changed Assumption	Break-Even Revenue	Revenue Gap	Risk Signal
Current plan	No change.	$71.2k	$58.9k cushion	Solid start, but the margin buffer is not wide.
Revenue shortfall	Monthly revenue falls 20% to about $104.1k.	$71.2k	$32.9k cushion	Slower enrollment cuts room for hiring and upgrades.
Fixed-cost pressure	Monthly fixed costs rise 10% to about $62.6k.	$78.2k	$51.9k cushion	Higher shop overhead lifts the floor fast.
Margin pressure	Variable expenses rise from 20% to 25% of revenue.	$75.9k	$54.2k cushion	Tooling waste or marketing drag pushes break-even up.
Combined pressure	Revenue falls 20%, fixed costs rise 10%, and variable load rises to 25%.	$83.5k	$20.6k cushion	It still clears break-even, but the safety margin gets thin.

Can this machinist training program prove enough paid students before you lock the workshop lease and buy the machines?

Founder checklist

Yes—test paid demand, the $655K startup build, and the Month 4 cash trough before you sign the lease or buy machines. This model needs a 27 to 29 active-student path, plus enough runway to reach break-even without squeezing staffing or safety.

1Paid Demand27-29 students

Verify you can enroll at least 27 to 29 active students while keeping recruitment marketing near 8% of Year 1 revenue before you sign the lease.

2Fixed Burn$52.2K/mo

Check the full monthly burn, not just the $12K lease, because payroll plus overhead drives the real break-even target.

3Tuition Mix$2,257/seat-mo

Price the program mix against the Year 1 weighted average of about $2,257 per active monthly seat, or the model will miss break-even even with full cohorts.

4Startup Capex$655K

Fund the machining centers, lathes, metrology lab, workstations, tooling, and buildout before opening, or the launch starts undercapitalized.

5Cash CushionMonth 4 / $486K

Keep at least the modeled $486K cash cushion through Month 4, when the cash trough hits, so the buildout and staffing ramp do not stall.

6Staffing Ramp1.0-3.0 FTE

Hire instructors with cohort fill, because the Lead CNC Instructor ramps from 1.0 FTE in Year 1 to 2.0 in Year 2 and 3.0 by Year 4, and safety rules must be locked before student machine time.
