Cost classification

Break-even gets more reliable when fixed overhead is separated from enrollment-driven spend. Here, Month 7 break-even depends on treating fees, instructor share, hosting, commissions, and paid marketing as volume-sensitive.

Expense	Cost	Break-Even Treatment	Common Mistake
Platform Software Licenses	Fixed	Count $1,500 per month in fixed overhead from Month 1 through Month 60.	Treating licenses as a per-learner charge.
Office Rent	Fixed	Use $2,500 per month in fixed overhead across the planning range.	Allocating rent by enrollment volume.
Payment Processing Fees	Variable	Apply 2.5% of first-year revenue, then use the lower annual rates in later years.	Burying card fees inside general admin.
Instructor Revenue Share	Variable	Apply 8.0% of first-year revenue as delivery expense before calculating contribution margin.	Ignoring the margin drag from instructor payouts.
Video Hosting & Streaming	Variable	Apply 4.0% of first-year revenue because usage rises with viewing and paid learners.	Assuming digital delivery has zero delivery expense.
Sales Team Commissions	Variable	Apply 3.0% of first-year revenue and keep it separate from fixed salaries.	Mixing commissions with payroll overhead.
Customer Support Specialist Wages	Semi-fixed	Model staffing in steps: 0.5 FTE in the first year, then 1.0 FTE in the second year.	Hiring full capacity before demand proves out.
Paid Marketing Budget	Semi-variable	Use the $150,000 first-year budget and test it against the $35 customer acquisition cost.	Calling all ad spend fixed overhead.

How does break-even change from a lean launch to a full-scale course model?

Scenario table

Break-even gets harder as fixed spend rises faster than margin. Here’s the quick math: lean needs about $64.5k in monthly revenue, base about $117.9k, and full about $181.4k, even as variable costs fall from 17.5% to 12.3%.

Planning cases only. Actual results will move with traffic, conversion, mix, and staffing pace.

Scenario	Monthly Revenue	Variable Costs	Fixed Costs	CM Ratio	Operating Profit	Break-Even Signal
Lean Year 1 launch	$51.0k	$8.9k	$53.3k	82.5%	-$11.2k	Needs about 1,793 paid learners to cover launch overhead.
Base Year 3 growth	$59.5k	$8.9k	$100.3k	85.1%	-$49.7k	Higher margin helps, but fixed spend still leaves a wide gap.
Full Year 5 scale	$68.7k	$8.5k	$159.1k	87.7%	-$98.8k	Best unit economics, but scale still has to rise fast.

What breaks the break-even plan if enrollment or margins slip?

Stress test

The plan has no cushion at the $645,000 base case, so even a small enrollment miss hits break-even fast. A 10% revenue shortfall, a 10% overhead bump, or a drop to 77.5% contribution margin each pushes the model into a gap.

Stress Case	Changed Assumption	Break-Even Revenue	Revenue Gap	Risk Signal
Current plan	No change; base case holds.	$645,000	$0 gap	No operating cushion at base revenue.
Revenue shortfall	Revenue lands 10% below the base case.	$645,000	$53,000 gap	Higher CAC or weaker trial-to-paid conversion will show up first.
Fixed-cost pressure	Fixed overhead rises 10% from the base case.	$710,000	$65,000 gap	Delay support hiring until enrollment density is there.
Margin pressure	Contribution margin falls from 82.5% to 77.5%.	$687,000	$42,000 gap	Discounting, refunds, or fee pressure can erase the cushion.
Combined pressure	Revenue is 10% lower, fixed costs rise 10%, and margin slips to 77.5%.	$776,000	$131,000 gap	Higher CAC and weaker conversion push the model six figures off plan.

Is the online course platform ready to break even before you commit to the $250K build?

Founder checklist

Test the funnel, pricing, and burn against the break-even model before you spend on the full build and Year 1 marketing. If the $36 blended monthly price, $35 CAC, and 5.0% to 25.0% funnel do not hold, the Month 7 break-even date slips.

1Demand proof$35 CAC

Confirm you can hold a 5.0% visitor-to-trial rate and a 25.0% trial-to-paid rate at about $35 CAC before you scale the $150K Year 1 marketing budget.

2Fixed burn$40.8K/mo

Make sure the $7.0K monthly overhead plus Year 1 wages still fit the plan, because that base burn drives the Month 7 break-even target.

3Checkout live$36/mo

Finalize the Core Learning, Advanced Skills, and Professional Certs prices, and turn on checkout and payment tracking before paid traffic so the $36 blended monthly subscription is real.

4Margin mix82.5% CM

Check that instructor share, video hosting, payment fees, and sales commissions stay near 17.5% of revenue, leaving about 82.5% contribution before fixed costs.

5Team rampMonth 13-19

Tie extra hiring to load, since the Platform Engineer starts in Month 13 and the Content Creator in Month 19, and support must still run cleanly before then.

6Cash buffer$612K by M6

Keep the reserve above the Month 6 trough and defer office or equipment spend if needed, because the model needs about $612K of minimum cash to stay on track.
