Growth Efficiency Index (GEI)


The Growth Efficiency Index (GEI) is a metric that evaluates the cost of earning $1 of net ARR. GEI below 1.0 is considered optimal revenue acquisition while a value over 1.0 means suboptimal revenue acquisition.


Growth Efficiency Index is calculated by dividing the current year's Sales and Marketing expenses by the Net New ARR of the Current Year.

Why it matters
