Formula
CPA = ad spend ÷ signups= 7.5
Note
This is a simplified model: it applies the counts, rates, prices and fees you enter to plain arithmetic. Every platform cut, payment fee, CPM, royalty per play and commission rate is a value you supply, because no platform's revenue share, advertising rate or payout rate is fixed: they change over time and differ by country, contract, category, audience and season. Engagement, open, click and unsubscribe rates are the standard definitions, but each platform and email tool counts interactions, reach, delivered mail and opens differently, so a rate is only comparable against numbers counted the same way; image-blocking and privacy features in particular make open rates unreliable. Revenue estimates ignore taxes, withholding, currency conversion, refunds, chargebacks, invalid traffic, minimum payout thresholds and payment delays. The churn projection assumes a constant monthly churn rate and a constant number of new subscribers, which real audiences never follow. Treat every figure as a rough planning estimate, not a forecast of what you will be paid, and check your own platform statements and any contract before relying on it. This is not financial, tax or legal advice.

How is cost per signup calculated?+
Divide total spend on a campaign or channel by the number of signups it generated. $500 in ad spend producing 100 signups gives a cost per signup of $5.
What counts as 'spend' for this calculation — just ad dollars?+
For a complete picture, include all directly attributable costs: ad spend, but also affiliate payouts, influencer fees, or promotional discounts tied specifically to that acquisition channel — using only raw ad spend understates the true acquisition cost.
How do I know if my cost per signup is 'good'?+
Compare it against the lifetime value (LTV) of an average signup — a sustainable ratio is typically at least 3:1 (LTV to acquisition cost), though the exact target depends on your margins, retention, and how quickly you need to recoup the cost.
Why does cost per signup differ so much between traffic channels?+
Different channels attract audiences at different points in intent — someone searching for your exact product converts more easily (lower cost per signup) than someone seeing a cold social ad, and channel competition and targeting precision also vary the price of that attention.
Is a lower cost per signup always better?+
Not necessarily — cheap signups from low-intent traffic often churn quickly and have low lifetime value, so a lower cost per signup paired with poor retention can be worse for the business than a higher-cost signup that stays and pays for much longer.
