Profit per Click Calculator
Every click as a small bet with a known payoff.
Profit per click
−$0.565
−$5,088 a month at 9,000 clicks
Each click loses $0.565. Buying more traffic makes the loss bigger — the fix is upstream, in conversion rate or order value.
How the Profit per Click Calculator works
A click is a small bet: it costs a known amount and returns contribution times conversion rate on average. Once profit per click is positive, more clicks is straightforwardly better — until the marginal click stops converting at the same rate, which is the point actually worth watching.

Frequently asked questions
How do I calculate profit per click?
Average order value times conversion rate times contribution margin, less cost per click. That is the expected profit from buying one more click.
Why is this more useful than ROAS?
Because it is a marginal figure rather than an average. ROAS tells you how the campaign did; profit per click tells you whether the next click is worth buying.
What if it is negative?
Buying more traffic makes the loss bigger. The fix is upstream — conversion rate, order value or margin — because nothing in bidding turns a negative expected value positive.
Does the average hold as I scale?
No. Marginal clicks convert worse than average ones, so profit per click falls as spend rises. Scaling stops where the marginal click hits zero, not where the average does.
