Sometimes it is easier to show percentage decrease as a negative number – to do this follow the formula above to calculate percentage increase – your answer will be a negative number if there was a decrease. In Dylan’s case the increase in hours between February and March is -10.5 (negative because it is a decrease). Therefore -10.5 ÷ 45.5 = -0.23. -0.23 × 100 = -23%.Although we have just covered how to calculate percent increase and percent decrease, sometimes we just are interested in the change in percent, regardless if it is an increase or a decrease. If that is the case, you can use the percent change calculator or the percentage difference calculator. A situation in which this may be useful would be an opinion poll to see if the percentage of people who favor a particular political candidate differs from 50 percent. The percentage increase calculator above computes an increase or decrease of a specific percentage of the input number. It basically involves converting a percent into its decimal equivalent, and either subtracting (decrease) or adding (increase) the decimal equivalent from and to 1, respectively. Multiplying the original number by this value will result in either an increase or decrease of the number by the given percent. Refer to the example below for clarification.

Math Example: How to calculate percentage increase, Decrease or Difference This example will explain how calculating increase and decrease works. To calculate percent difference, you need to follow these steps: Percent Problem: You need to calculate percent % increase from 2 to 10. First Step: find the difference between two numbers, in this case, it's 10 - 2 = 8. Second Step: Take the difference, 8, and divide by the original number: 8/2 = 4. Last, multiply the number above by 100: 4*100 = 400%. You're done! You calculated difference of a number in percent, and the answer is a percentage increase of 400%.Let's review what we've learned. A percentage increase or decrease is the amount of increase or decrease expressed as a percentage. To calculate it, we first calculate the first total and then the second total. If we are comparing two consecutive years, the first year gives us the first total, and the second year gives us the second total. Then we determine if there is an increase or decrease happening. Then we calculate the amount of this increase or decrease. To find the percentage, we divide the amount of increase or decrease by the first total and multiply by 100. (Source: study.com)
