200 revenue per customer, 70 COGS, 40 servicing = 90 profit per customer. 45% margin. Combined with customer count, this tells you total profit. Combined with customer acquisition cost, shows whether unit economics work.

A worked example

Try the defaults: revenue per customer of 200, cogs per customer of 70, service cost per customer of 40. The tool returns 90.00. You can adjust any input and the result updates as you type — no submit button, no reload. That's the real power here: seeing how sensitive the output is to one or two assumptions.

What moves the number most

The result responds to Revenue per Customer, COGS per Customer, and Service Cost per Customer. Not every input has equal weight. Flip one at a time toward extreme values to feel which ones move the needle most for your situation.

The formula behind this

Revenue minus variable per-customer costs. Everything the calculator does is shown in the formula box below, so you can check the math against your own spreadsheet if you want.

Using this as a check-in

Re-run this every three months. A single reading tells you where you stand; four readings tell you whether things are improving. The trend matters more than any individual snapshot.

What this doesn't capture

The score is a composite of the inputs you provide. Life context — job security, family obligations, health, housing — doesn't appear in the math but shapes the real picture. Use the number as a prompt, not a verdict.

What to calculate alongside this

One figure by itself is fragile. The customer lifetime value calculator, the gross profit calculator, and the airbnb host profit calculator cover adjacent ground — the answer to any one of them changes how you read the output from this tool. Worth a few minutes each, honestly.

Frequently Asked Questions

Is CAC a variable cost?
Treated separately. Customer acquisition cost is a one-off at sign-up. Profit per customer is recurring; LTV / CAC is the full unit-economics picture.
What's a healthy margin?
Varies by industry. SaaS often 70-90%, retail 10-30%, manufacturing 15-40%. Compare within industry.
How to improve?
Raise prices (most powerful), reduce COGS, streamline service. Often one of these has 20-40% improvement available.
Per customer or per sale?
Subscription/service: per customer. Product sale: per transaction. Depends on business model.
