Build a simple financial model covering revenue, gross margin, operating costs, contribution margin, cash burn, runway, and break-even.

Model three scenarios: Conservative, Base Case, and Upside, clearly stating every assumption used.

Calculate:

2. Gross and contribution margins
3. Break-even customer volume and revenue
4. CAC payback period
5. Estimated runway
