Häufig gestellte Fragen

How do I calculate percentage decrease?

Subtract the new value from the original value, divide by the original value, and multiply by 100. Example: from 200 to 150 → (50 ÷ 200) × 100 = 25%.

Why is my result negative?

A negative result means the value actually increased. Swap your inputs or use the percentage increase calculator.
