Every driver below is a fictional assumption. The spreadsheet contains these inputs and working formulas. Revenue is entered independently; it is not calculated from customer acquisition, churn, or market share.
Calculation method and limits
Revenue and OpEx compound at their annual growth rates. COGS = revenue × (1 − gross margin). EBITDA = gross profit − OpEx. Tax = 21% of positive EBITDA, with no loss carryforwards. Operating cash = EBITDA − tax. Ending cash = previous cash + operating cash. Values retain precision; only displayed amounts are rounded. Negative cash shows a funding gap. Working capital, capex, debt, and financing transactions are excluded.
