Formula & Methodology
The ABC analysis formula is based on the Pareto Principle, which states that 80% of effects come from 20% of causes. Here’s how to calculate ABC analysis:
- Calculate the total value of all items.
- Calculate the total usage of all items.
- For each item, calculate its value percentage (Value / Total Value) and usage percentage (Usage / Total Usage).
- Categorize items into A, B, and C based on their value and usage percentages.
