Question from Paul: Could you please help me with this question. I was paying $98.00 a month for my health insurance premium, now it is up to $125.83 How much of an increase is that as a percentage increase, and how can I do this on a calculator. I'd like to know how much my increase is as a percentage. |
Hi Paul,
Percentage increase is the increase, as a percentage of the old number. That is it is
(new number - old number)/old number × 100
For the numbers you sent that's
(125.83 - 98.00)/98.00 × 100 = 28.40%
