Percentage Decrease Calculator

Subtract the new value from the original, divide by the original, then multiply by 100. Example: price dropped from $200 to $150 → (50/200) × 100 = 25% decrease.

No. If you increase 100 by 50%, you get 150. But decreasing 150 by 50% gives 75, not 100. To return to the original after a 50% increase, you need a 33.3% decrease.

Multiply the number by (1 - percentage/100). For example, to decrease 200 by 25%: 200 × 0.75 = 150.
