How do I use the Percentage Decrease?
Enter the required values in the form. The result updates live as you type. You can adjust decimal precision, copy the answer, or share a link with your inputs pre-filled.
Can a percentage be greater than 100%?
Yes. Percentages above 100% mean the part is larger than the whole — for example, 150% of 80 is 120. Growth, markup, and error calculations often exceed 100%.
Why is my answer a decimal?
Many percentage calculations produce fractional results (for example, 15% of 250 is 37.5). Use the precision selector to control how many decimal places are shown.
