Unit Economics
Find out whether each sale makes money after every cost, and which channel to keep, fix, or stop.
Not tax, legal, or investment advice.
A one-page sheet with profit per sale, cost to win a customer by channel, payback, and a keep, fix, or stop call for each channel.
Revenue can grow while every sale loses money. This skill subtracts every direct cost to find what a sale really leaves you.
It computes the cost to win a customer by channel, the value of a customer (capped so one good month cannot inflate it), the ratio, and payback in months.
It tests how the answer changes if costs rise or customers leave faster, then ranks the three levers that move profit most.
- Price and every direct cost per sale
- Spend and new customers by channel
- Repeat rate or churn
- Fixed monthly costs
- Inputs table
- Contribution per sale
- Cost to win and value by channel
- Ratio, payback, break-even sales
- Sensitivity lines
- Channel verdicts
- Three levers
