Formula

Practical considerations:
Activity definition: Specify what qualifies as an active customer (e.g., a purchase, login, or usage event) and apply consistently.
Timeframe selection: Use a standard period (e.g., 30 days for monthly active customers) to ensure comparability.
Data accuracy: Verify customer identities to avoid double-counting across devices or platforms.
Seasonal factors: Adjust for seasonal spikes (e.g., holidays) that may temporarily boost active customer numbers.
