Step by step
- 01
Start with revenue assumptions
Price × units × growth. Keep it monthly for year 1.
- 02
Build the income statement
Revenue − COGS = gross profit. Subtract operating expenses to get EBITDA.
- 03
Link the cash flow
Start with net income, add back non-cash items, account for working capital.
- 04
Balance the balance sheet
Assets = liabilities + equity. If it doesn't balance, your linking is off.
- 05
Add scenarios
Best, base, worst — toggle with a single cell.
