Break-even chart Revenue Total costs
Which expenses are fixed and which move with sales in a computer vision software business?
Cost classification
Break-even is reliable only when monthly burn is split from usage-linked spend. If cloud, storage, commissions, or support labor sit inside general overhead, Month 3 break-even can look stronger than the operating reality.
Expense

Break-Even Treatment
Common Mistake
Office rent, $5,000/month
Fixed
Count in monthly fixed burn from Month 1 through Month 60.
Assuming rent flexes down when revenue misses plan.
Operational software licenses, $1,500/month
Fixed
Include as recurring fixed overhead before contribution margin.
Carry as fixed operating expense across the planning period.
Leaving it out because it does not serve customers directly.
CEO, lead AI engineer, developer, and sales payroll
Fixed
Treat committed salaries as fixed burn within each staffing plan.
Modeling payroll as if it falls automatically with sales volume.
Cloud infrastructure, 7.0% of first-year revenue
Variable
Deduct from revenue before measuring contribution margin.
Hiding inference spend inside general overhead.
Data processing and storage, 3.0% of first-year revenue
Variable
Scale with customer usage and transaction volume.
Forgetting that video and image workloads raise storage needs.
Sales commissions and bonuses, 6.0% of first-year revenue
Variable
Apply against sales-driven revenue before break-even math.
Counting gross revenue without the payout tied to closing it.
Customer success payroll
Semi-fixed
Add in steps once support load rises with the customer base.
Waiting too long to model support capacity after paid trials convert.
How does break-even change from a lean launch mix to a base case and a full deployment?
Scenario table
Break-even moves up fast as the mix shifts toward higher-priced plans and heavier support. Margin improves, but fixed payroll and service load rise too, so revenue has to climb just to stay at zero.
Planning cases only; these figures show break-even mechanics from the model inputs, not guaranteed results.

What pushes this break-even plan off track?
Stress test
The base case works at about $919K of revenue, but it’s fragile if 20.0% trial-to-paid slips, cloud load rises, or sales payroll starts early. At an 82.5% contribution margin, small misses move the break-even line fast.

Stacked misses push break-even well beyond the plan.
What should you verify before locking in office rent and specialized hires for this computer vision platform?
Founder checklist
Test paid demand, pricing, and usage before you commit to the office and extra hires. In Year 1, the model only works if 3.0% of visitors start trials, 20.0% of trials convert, and recurring revenue can cover about $63.3K of monthly fixed burn before variable costs.
1Demand Proof3.0% / 20.0%
Confirm the trial funnel and paid close rates in the first operating year before you sign fixed commitments.
2Fixed Burn$63.3K/mo
Make sure monthly payroll plus overhead can be covered, since office rent alone is $5K and core staff drive most of the burn.
3Unit Margin82.5% CM
Keep cloud, storage, commissions, and payment fees near the modeled levels so margin stays high enough for breakeven.
4Usage Load500 / 2,000 / 10,000 tx
Test support and compute at each active-customer usage level, and delay extra sales, data science, and customer success hires until recurring revenue pays for them.
5Cash Floor$848K min cash
Hold the Month 2 cash floor, because capex totals about $100K and the model does not reach breakeven until Month 3.
6Launch CAC$150 CAC
Track customer acquisition cost against the Year 1 target and keep enterprise setup work tied to recurring revenue, not custom one-off engineering.
