What the result means
It converts the entered assumptions into a consistent estimate of google ads return on investment. The result is most useful for comparison and planning when every input covers the same scope.
State which costs and attribution rules are included whenever reporting ROI. Recalculate when the underlying inputs change, and use source records rather than memory for material decisions.

The example illustrates the mechanics only. Replace every example value with data that reflects the user’s actual period, account, policy, or scenario.
