CPA Calculator — the easiest way to estimate your cost per action based on CPM.

A quick and easy way to calculate the cost per acquisition (CPA) of your ads.

CPA using CPM

1

Determine your cost per mille (CPM)

Begin by identifying your cost per mille (CPM), which represents how much you pay for 1,000 ad impressions in a campaign. You can easily obtain this figure using our CPM calculator.

2

Determine your click-through rate (CTR)

Next, enter your click-through rate (CTR). If you do not already have this metric, calculate it by dividing total clicks by total impressions and multiplying by 100. CTR is expressed as a percentage (for example, 35%). Enter the numeric value only, without the percentage sign.

3

Determine your conversion rate

Finally, enter your conversion rate, which indicates the percentage of clicks that result in conversions. Calculate it by dividing total conversions by total clicks and multiplying by 100. For example, if you have 100 clicks and 50 conversions, your conversion rate is 50. Enter “50” into the calculator.
