Does each sale make you money?
Put in one month of numbers and see your margin per order, what a customer costs and what they're worth, how fast they pay you back, and which change would help most. New to this? Read the playbook.
The four numbers
What the calculator works out
- Margin per order
- Order value minus everything that order costs you: goods, packaging, delivery, payment fees, refunds and failed deliveries. Also called contribution margin.
- Cost to win a customer
- Everything you spent on getting new customers in a month, divided by the new customers you got. Also called CAC.
- Customer lifetime value
- The margin one customer brings in across all their orders while they keep buying. Also called LTV.
- Payback
- How many months of a customer's margin it takes to earn back what you spent to win them.
Need these numbers inside your own system?
I build commerce platforms and back-office tools that track this automatically from your real orders, payments and marketing spend.
