Your AI return is how much of your AI tooling investment actually turns into shipped software. The formula is simple: (Outcome − Rework) ÷ Investment.
Most teams today measure only one side: how much code gets generated, how many licenses get used. But generating isn't shipping. A change written in twenty minutes that waits nine days for review, or bounces back twice over an ambiguous acceptance criterion, consumed AI budget without producing value.
It matters now because AI spend is already a visible budget line, and the question “is this paying off?” arrives before the evidence to answer it exists.
