What CPC can you actually afford to pay?
Enter your campaign’s CPC and conversion economics to see if you’re actually profitable — and the maximum CPC you can afford before every click starts costing you money. Use it to set bid ceilings, sanity-check vendor proposals, and figure out which lever (CPC, CR, AOV, or margin) to fix first.
What you pay the ad platform per click.
Optional. Used to compute CPM.
Share of clicks that turn into a sale.
Average revenue per conversion.
Percent of AOV left after COGS, fees, and shipping.
Current break-even CPC is $0.96. Either get CPC under that, raise CR, or improve AOV/margin.
How profit changes as your CPC moves. The break-even line is where profit hits zero.
Even small CR lifts move the needle hard. This is why pre-testing creatives matters more than bidding harder.
| CR change | New CR | Profit per click | vs now |

| +10% | 3.30% | -$1.444 | +$0.096 |

AOV × conversion rateAOV × conversion rate × gross margin(AOV × CR × margin) − CPCAOV × CR × marginCPC / (AOV × margin)1 / margin(break-even CPC − CPC) / break-even CPCThese are gross-margin economics. They don’t include fixed costs, returns, or LTV from repeat purchases — so a thin positive number here is still risky.
