Calculate CPA (cost per acquisition) or CPL (cost per lead) from spend and conversions.

The CPA / CPL Calculator works out your cost per acquisition (CPA) or cost per lead (CPL) from your ad spend and the number of conversions or leads. It is the metric that ties spend directly to results, so it is the clearest way to judge whether a campaign is profitable against your target payout.
CPA (cost per acquisition) is the average amount you spend to get one conversion. It is calculated as ad spend divided by conversions. CPL (cost per lead) uses the same formula with leads.
CPC measures the cost of a click, while CPA measures the cost of a completed conversion. CPA is always at least as high as CPC because not every click converts.
