Percentage increase calculator is used to calculate the increased value of an item over a time period in terms of percentage. It can be expressed in percentage form. It can be calculated by increased value over a original value multiplied by 100.
Percentage Increase = (New value – Old value)/ (Old value) x 100
Example 1: What is the percentage of increase when a number is modified form 55 to 65?
Given that New value = 65
Old value = 55
Difference = 65- 55=10
Percentage Increase = (10/55) x 100
= 0.18181818 x 100
= 18.181818 %.
= 18.18 % (nearest hundredth).
So the number is increased by 18.18%.
Example 2: What is the percentage increase in the salary of James if his salary is increased from $
149 to $199 per month?
Given that New value =$199
Old value = $149
Difference = $ 199 - $ 149 = $50
Percentage Increase = (50 /149) x 100
= 0.33557 x 100
= 33.56% (nearest hundredth)
James salary is increased by 33.56%.

Your tutor has been such an inspiration to me as I have difficulty getting some of the physics concepts down and truly understanding them. She takes the time to fully explain each and every aspect of any problem I might ask for help and always with encouragement and humor.
