How the model works
- Monthly contribution = completed cases × gross contribution per case after direct case costs.
- Monthly operating result = monthly contribution − fixed costs.
- Break-even cases = fixed costs ÷ contribution per case, rounded up, when contribution is positive. No fixed costs means break-even at zero cases.
- Working cash after setup = starting cash − setup costs. Any setup shortfall is shown separately. The model does not calculate runway or cash-flow timing.
Hypothetical example and limits
Illustrative example: setup 2,000, starting cash 5,000, fixed costs 1,000 and 12 cases contributing 50 each produce 600 contribution, a -400 monthly result, 3,000 working cash after setup, and break-even at 20 cases. These are not prices, market averages or an earnings forecast.
The calculation is a static monthly scenario only. It excludes tax, financing, depreciation, seasonality, collection timing, restricted client funds, supplier refunds and FX changes; it does not forecast runway. Do not treat supplier-bound money as unrestricted cash. The readiness checklist is not a license, legal advice or certification.
