Find your maximum CPC and the minimum CR, deposit rate and payout for a target ROI.
Quick answer
Enter payout, click→lead CR and deposit rate — get max CPC (equal to EPC at 100% ROI). Add your actual CPC to see the minimum CR, deposit rate and payout needed to break even.
At a 100% target ROI the max CPC equals EPC — bidding above it is guaranteed loss.
Max CPC is the highest click price at which a campaign still hits your target ROI. The math is straightforward: EPC = payout × click→lead CR × deposit rate, and at a 100% target ROI your max CPC is exactly your EPC. Any bid above EPC loses money on every click; anything below leaves profit.
The tool also solves the reverse problems that matter before you buy traffic. Enter the CPC a source actually charges, and you get the minimum click→lead conversion, minimum deposit rate and minimum payout needed to stay above water. If a push network charges $0.008 per click but your funnel needs a 3% click→lead rate to break even, you know the bar before spending a dollar.
A worked example: a CPA offer pays $290 per deposit. Your landing page converts 10% of clicks to leads, and 10% of leads deposit. EPC = 290 × 0.10 × 0.10 = $2.90 — that is your absolute max CPC at break-even. Want a 130% ROI? The ceiling drops to $2.23. Now flip it: if the source only sells $4 clicks, the tool shows you need a 13.8% click→lead CR or a payout of at least $400 — whichever lever is easier to pull.
Use it during offer selection, not after a failed test. Comparing two offers with payouts of $200 and $290 takes ten seconds: the second one raises your max CPC by 45%, which often decides whether an expensive traffic source is even viable.
