Formula
Growth = (Current − Prior) ÷ Prior · Future = Current × (1 + Growth)ⁿ
FAQ
What if the prior period was unusual?
Normalize it. A one-time spike or dip distorts the rate — use a representative base or a multi-period average.
Should I project with net or gross growth?
Use net growth (after churn/returns) for revenue projections; gross growth overstates what persists.
