How To Calculate Percentage Increase



A percent increase is computed when a quantity grows bigger. To calculate the percentage increase is not complicated if you know the simple formula to use.

The basic formula is:
Percent increase = (New Amount Original Amount)
____________________________
Original Amount

For example:
Originally, there were 100 people in the office. The office decides to expand and hires 50 more people. Now, there are 150 people in the office. What is the percentage increase? By using the simple formula above, you will first find the different between the two numbers (150 - 100 = 50) to figure how much the total increase is. Then you divide the number you come up with by the original amount (50/100 = .5). The final step is to get a percentage form which you can do by moving the decimal to the right two places and the adding the percent sign. The final answer would be a 50 percent increase in workers in the office.
Another example:
Last year, 300 people attended the annual flower festival. This year, 500 people attended. What is the percentage increase?


Step 1: 500 300 = 200
Step 2: 200/300 = .67
Step 3: Move the decimal to the right two places to get a percentage increase of 67%.
