How it works
- Absolute price change equals the new price minus the original price.
- Percentage change compares that difference with the original price.
- A negative result represents a price decrease rather than an increase.
Percentage Change = (New Price − Original Price) / Original Price × 100
Frequently asked questions
Can this calculator show a price decrease?
Yes. If the new price is lower than the original price, the percentage change is negative.
Why can't percentage change use an original price of zero?
Percentage change requires division by the original value, so zero cannot be used as the reference amount.
Is price increase the same as markup?
No. Markup specifically compares selling price with cost, while this calculator compares any old and new price.
