Which language learning app expenses stay fixed, and which move with sales?

Cost classification

Break-even gets unreliable when committed spend is treated like usage spend. Separate stable burn from revenue-linked fees so Month 9 break-even reflects the real cash load.

Expense	Cost	Break-Even Treatment	Common Mistake
App Store Fees	Variable	Apply 15.0% of first-year revenue, falling to 13.0% by the mature year.	Modeling it as fixed and overstating margin at low subscriber volume.
Cloud Hosting & AI API Usage	Variable	Apply 3.0% of first-year revenue, then reduce to 2.0% by the mature year.	Ignoring usage growth as lessons, sessions, and AI calls rise.
Digital Advertising & Content Creation	Variable	Apply the revenue-linked layer at 1.0% in the first year, declining to 0.6%.	Combining it with the committed annual marketing budget.
Customer Support Tier 1	Semi-variable	Use the 0.5% first-year revenue layer, then track staffing separately as volume grows.	Treating support as purely variable when payroll adds step changes.
Annual Marketing Budget	Semi-fixed	Spread the $200,000 first-year budget across months, about $16,667 per month.	Treating all marketing as variable even though spend is committed.
Payroll	Semi-fixed	Use first-year payroll of $700,000, about $58,333 per month, then step up with FTE.	Using one flat salary run-rate while developer and support headcount rises.
Office Rent	Fixed	Include $3,000 per month throughout the 60-month model period.	Scaling rent with subscribers instead of treating it as stable burn.
Tools, Legal, Admin, Cybersecurity, Payment Fixed Fees, Content Licensing, Utilities	Fixed	Include $5,100 per month as recurring overhead outside subscriber volume.	Dropping small fixed tools and admin items from break-even math.

How does break-even change from lean launch to base scale and full growth for this language learning app?

Scenario table

Break-even gets easier as the plan shifts to higher-priced tiers and lower fee drag, so each paid subscriber covers more of the fixed base. The full-growth case has the best cushion, but it only works if retention and CAC support the hiring ramp.

Planning cases only; actual results will move with retention, CAC, and content costs.

Scenario	Monthly Revenue	Variable Costs	Fixed Costs	CM Ratio	Operating Profit	Break-Even Signal
Lean launch	$103.5k	$20.2k	$69.3k	80.5%	$14.0k	Above break-even, but the cushion is still modest.
Base scale	$145.7k	$27.2k	$98.4k	81.3%	$20.1k	This is the planning anchor; profit stays positive if CAC holds.
Full growth	$209.4k	$37.1k	$143.3k	82.3%	$29.0k	Strongest cushion, but it depends on keeping the premium mix intact.

What breaks the break-even plan for this language learning app?

Stress test

The plan stays tight unless acquisition stays cheap and trial conversion holds. A 10% revenue miss, a 10% cost increase, or a 5-point margin drop can each push the app into a six-figure monthly gap.

Stress Case	Changed Assumption	Break-Even Revenue	Revenue Gap	Risk Signal
Current plan	No change.	$1.03M	$0 gap	Breakeven lands in Month 9, so cash stays tight.
Revenue shortfall	Revenue runs 10% below plan.	$1.03M	$83k gap	A small top-line miss quickly becomes a monthly cash hole.
Fixed-cost increase	Fixed costs rise 10% above plan.	$1.14M	$104k gap	More payroll or overhead pushes breakeven above the base case.
Margin pressure	Variable expense pressure cuts contribution margin to 75.5%.	$1.10M	$69k gap	Higher app store, cloud, or support costs lift the break-even bar.
Combined pressure	Revenue is 10% below plan, fixed costs rise 10%, and margin falls to 75.5%.	$1.21M	$213k gap	CAC above $15, visitor-to-trial below 3.0%, or trial-to-paid below 15.0% can break the model.

What should the founder verify before locking in heavier spend on this language learning app?

Founder checklist

Don’t add headcount or heavier ad spend until Year 1 ARPU holds near $15, the funnel stays near 3.0% to trial and 15.0% to paid, and cash can carry the business to Month 9. That’s the only way the current burn stays believable.

1Blended ARPU$15 ARPU

Verify the Year 1 mix stays near 60% Basic Learner, 30% Fluent Speaker, and 10% Master Linguist, because that blend is what gets you to $15 average monthly revenue per paid user.

2Trial Funnel3.0% / 15.0%

Check that visitor-to-free-trial stays near 3.0% and trial-to-paid near 15.0%, or the funnel will not feed enough paid users to justify more spend.

3CAC Guardrail$15 CAC

Keep Year 1 customer acquisition cost at or below $15, because acquisition cost above target can wipe out the margin on a low-price subscription.

4Margin Stack80.5% CM

Confirm app store fees start at 15.0% and the other variable costs stay near 4.5% of revenue, leaving about 80.5% contribution margin before fixed costs.

5Fixed Burn$66.4K/mo

Freeze new recurring spend until you are comfortable with the current fixed load of about $66.4K a month from payroll and overhead.

6Runway Gate$599K / $82.5K/mo

Hold at least $599K of cash through Month 9, and do not add linguist or support payroll until monthly revenue can clear about $82.5K.
