Cost classification

Break-even gets unreliable when recurring overhead, usage fees, and scale-up staffing are mixed together. For this model, separate stable monthly spend from revenue-linked fees before testing the Month 11 break-even target.

Expense	Cost	Break-Even Treatment	Common Mistake
CEO salary	Fixed	Include the $120,000 annual salary as stable monthly overhead across the planning range.	Excluding founder payroll makes break-even look earlier than the cash plan supports.
Lead Software Developer payroll	Fixed	Treat the first-year 1.0 FTE at $110,000 annually as base product payroll needed to operate.	Moving developer payroll into variable spend hides the true monthly burn.
Office rent	Fixed	Include $1,500 per month from Month 1 through Month 60 as recurring overhead.	Dropping rent from break-even because it is small understates required revenue coverage.
Technology Infrastructure Cloud Hosting	Variable	Apply the first-year 4.0% of revenue charge as usage-linked delivery expense.	Treating hosting as flat forever ignores subscriber load as volume rises.
App Store Commissions	Variable	Apply the 3.0% of revenue commission directly against subscription sales.	Calculating break-even on gross subscription revenue overstates margin.
Digital Marketing & Advertising	Variable	Use the first-year 10.0% of revenue assumption when testing contribution margin.	Mixing the $250,000 annual marketing budget with this percentage can double count acquisition spend.
Customer Support Specialist payroll	Semi-fixed	Model support staffing in steps, from 0.5 FTE in the first year to higher capacity later.	Assuming support scales smoothly with each subscriber misses hiring jumps and training drag.
Content Production & Licensing	Variable	Apply the first-year 3.0% of revenue charge as content tied to subscription growth.	Loading the $183,000 launch capex into monthly overhead distorts operating break-even.

How does break-even shift from lean to base to full subscription mix?

Scenario table

Break-even shifts because each step up in pricing mix lifts margin, while CAC falls from $30 to $20 and trial-to-paid conversion rises from 15% to 24%. But support and growth scale also lift fixed costs.

Planning assumptions only; actual break-even will move with conversion, CAC, and support costs.

Scenario	Monthly Revenue	Variable Costs	Fixed Costs	CM Ratio	Operating Profit	Break-Even Signal
Lean Year 1 mix	$527.5K	$105.5K	$422K	80%	$0	Lowest revenue hurdle, but the cushion is thin.
Base Year 3 mix	$601.2K	$96.2K	$505K	84%	$0	Higher margin helps, but fixed spend still keeps break-even near $601K.
Full Year 5 mix	$710.3K	$92.3K	$618K	87%	$0	Best margin mix, yet the larger support and growth base pushes the hurdle higher.

What breaks first if revenue slips or costs rise for this personal fitness app?

Stress test

The plan clears break-even at about $527K in annual revenue, but it has very little cushion. A 15% revenue miss, a 5-point margin hit, or a 10% fixed-cost rise can push it back into a cash gap.

Stress Case	Changed Assumption	Break-Even Revenue	Revenue Gap	Risk Signal
Current plan	No change.	$527K	$0 cushion	No buffer for CAC or conversion slippage.
Revenue shortfall	Revenue falls 15% to $448K.	$527K	$63K gap	A small top-line miss opens a real cash hole.
Fixed-cost pressure	Fixed overhead rises 10% to $464K.	$580K	$53K gap	Overhead growth pushes break-even higher.
Margin pressure	Variable expense load rises from 20% to 25%.	$562K	$35K gap	Fee creep cuts contribution margin to 75%.
Combined pressure	Revenue falls 15% and fixed costs rise 10%.	$580K	$128K gap	Month 14 cash pressure shows up fast.

Can you prove the fitness app will break even before you lock the build and ad spend?

Founder checklist

Test the $10, $20, and $40 plans, the funnel, and the $30 CAC target before you scale. The model only works if the weighted price holds near $16, contribution stays near 80%, and cash can absorb the Month 14 low point.

1Plan demand$10 / $20 / $40

Verify buyers want the Basic Fitness, Pro Trainer, and Elite Performance tiers before you push the premium mix.

2Trial proof3.0% → 15.0%

Confirm visitors convert to trials and trials convert to paid users before you spend harder on ads.

3CAC cap$30

Keep Year 1 acquisition cost at or below $30, or the planned $250,000 marketing budget will buy too few paying users.

4Margin mix$16 / 80% CM

Check that the weighted monthly price stays near $16 so cloud, app store, marketing, and content costs still leave about 80% contribution margin, which is the cash left after variable costs.

5Build cap$145K

Hold app development, studio equipment, and design assets to the $145,000 cap before you add more launch spend.

6Runway gate$521K / Month 14

Start support at 0.5 FTE and keep cash through the Month 14 low point until paying users are around 3,294, or fixed payroll will outrun the break-even plan.
