Is a 25% decrease the same as keeping 25%?
No. A 25% decrease removes 25% of the original and leaves 75%. The remaining multiplier is 1 - 25/100 = 0.75.
Percentage Decrease Calculator
Calculate the final value after a percentage decrease by separating the original baseline, the amount removed, and the remaining value.
Start with the original, not the final
A percentage decrease is measured from the original value. A 30% markdown removes 30% of the starting price and leaves 70%, so the remaining multiplier is the part that matters.
Calculate a final-after-decrease value
- Enter the original value.
- Enter the decrease percent.
- Calculate the removed amount.
- Subtract the removed amount from the original.
- Check that units stay consistent.

FAQ
Why do markdowns, shrinkage, and depreciation use the original value?
The decrease percent is defined from the starting amount. The removed amount changes when the original price, quantity, or asset value changes.
