The calculator uses the percentage formula:

Where:

• \( value \) — The part of the whole you're measuring
• \( total \) — The complete or whole amount

5. Frequently Asked Questions (FAQ)

A: The calculator will show a percentage greater than 100%, which means the value exceeds the total amount.

Q2: Can I calculate percentage decrease?
