About

Automatically converts the "get an additional X conversions for Y cost" to a marginal acquisition cost in Google Ads - really useful for getting a feel of where your optimal Target CPA should be.

When you click 'Edit Target CPA' in Google Ads, you'll automatically see the Marginal CAC calculated and added into your budget popup.

Please note - the marginal cost and conversion increases are calculated by Google Ads. It's up to you to judge how accurate they are.
