How to use it
Make the worksheet part of the work.
Use contribution after variable delivery costs, not gross revenue.
Use qualified leads with a consistent definition.
Compare low, central and high assumptions against available sales capacity.
Check actual customer and refund data before increasing spend.
Worked example
Illustration assumptions: $2,000 marketing cost; 100 qualified leads; 20% close rate; $250 contribution/customer. Expected contribution=$5,000; after marketing=$3,000; acquisition cost=$100/customer; break-even=8 customers. This is arithmetic, not a forecast.
