A look inside

This is a real slice of the Inputs sheet from the actual file — not a screenshot, and not a mock-up. Cells shown in violet are live formulas, exactly as they arrive.

#	INPUTS	B
2	Sales & marketing spend (month)	£62,000
3	New customers won (month)	48
4	ARPA (monthly)	£189
5	Gross margin	78.0%
6	Monthly logo churn	2.8%
7	Expansion revenue rate	0.8%

Rows 2 onward of ‘Inputs’. The workbook ships with sample data throughout so every formula has something to calculate the moment you open it.
