Reverse Percentage Calculator
Enter the final price (after the percent change) and the percent — the original price will be found. Great for finding the original of discounted or taxed prices.
Enter values — result will show here live.
How to use
- First choose whether the value increased or decreased.
- Enter the final value and percent.
- You will get both the original value and the change amount.
Note: For increase: original = final / (1 + p/100). For decrease: original = final / (1 - p/100). If decrease is 100% or more, the original cannot be found.
