"nCAC is $53." Good or bad?

Nobody in the room can answer that. "$53 against a breakeven of $66" — now you know you can scale. A number without its threshold decided nothing. This calculates yours from two inputs you already have.

What's inside

A calculator, not a checklist.

Enter your margin and your first-order AOV. Every threshold below computes live, and your own numbers get read against them — no spreadsheet, nothing sent anywhere.

Breakeven nCAC — the most you can pay for a customer and still profit on the first order
Max nCAC at 6 months — the ceiling if you're willing to wait for the repeat
Breakeven NC-ROAS and MER — same formula, different scope, and why the gap is the rest of your marketing
The eleven numbers, split across three cadences: monthly, weekly, quarterly
Every formula, written out — contribution, payback, 6-month compound, repeat rate
What's excluded and why — CPA, blended ROAS, LTV∶CAC, CPM/CTR/CVR

The rule behind it

A metric earns its place by changing a decision. Everything else is a screenshot. Every threshold here comes from your own P&L — none of them is a benchmark borrowed from a brand that isn't yours, which is why the calculator asks for your numbers instead of quoting someone else's.
