How to calculate percentage decrease

Percentage decrease is based on the amount you began with, not the final amount. That baseline makes a $10 reduction mean something different on $20 than it does on $200.

Formula: ((original value − new value) ÷ original value) × 100

1. Subtract the new value from the original value to find the amount removed.
2. Divide the reduction by the original value.
3. Multiply by 100 to show the reduction as a percentage.

Example: a subscription falls from $60 to $45

The reduction is $15. Divide $15 by the original $60 to get 0.25, then multiply by 100. The subscription price decreased by 25%.
