Start with the question you need to answer

Use ROAS and ACOS to describe attributed revenue relative to media spend. Use break-even ROAS to connect an order's contribution to a media allowance. Use allowable CAC when you need to separate total acquisition cost from the amount left for media per new customer.

These tools calculate from your inputs. They do not connect to an ad account, predict campaign performance, or establish incremental sales. Each page explains its cost and revenue definitions, shows an illustrative example, and links to primary sources and a fuller guide.

For the decisions around the calculation, explore budget and unit economics or check your measurement definitions.
