• Using an incomplete total when comparing multiple cases.
• Confusing simple percentage with percentage change.

What the result helps you review

• A main calculated result based on the values you entered.
• Context on how to interpret the number before using it in a real decision.
• Examples and related reading that help you compare scenarios.

When you should verify the result

Formula

Percentage = (value / total) x 100
