Month-over-month (MoM) analysis compares data from one month to the previous month to identify trends, growth patterns, and performance changes. It's a fundamental tool for tracking business metrics and KPIs.

What is Month-Over-Month Analysis?

Definition

Comparison of consecutive months
Measures short-term performance changes
Identifies trends and patterns
Key metric for business monitoring

Formula

MoM Growth = ((Current - Previous) ÷ Previous) × 100
MoM Change = Current - Previous
Expressed as percentage or absolute value
Can be positive or negative
