Percent change in sales 2013-06-04
From Sui:
Hi,

I would like to ask your favor for reviewing the following percent change in sales calculation, did I do it right? I am surprise/wondering with the big amount of the percentage result. Your assistance and guidance would be highly appreciate.

Sales for month of August 2000: 5,198,750 IDR Sales for month of October 2000: 62,291,700 IDR Difference = 62,291,700 IDR - 5,198,750 IDR = 57,092,950 IDR Percentage change = 57,092,950 IDR : 5,198,750 IDR = 10.98 X 100 = 1,098%

Sales for month of February 2008: 1,664,800 IDR Sales for month of August 2008: 161,715,307 IDR Difference = 161,715,307 IDR - 1,664,800 IDR = 160,050,507 IDR Percentage change = 160,050,507 : 1,664,800 = 96.14 X 100 = 9,614%

Thanking you,
Sui

Inverting fractions and percentage 2013-05-18
From Carlos:
If I calculate the percentage change between two fractions, say, 1/100 and 2/100, I get 100% change. Now, if I flip denominator and numerator, 100/1 and 100/2, and repeat the calculation, I get a 50% change. Why are the percentages different?
Thank you very much

Plotting percentage change 2006-10-11
From Beckie:
I have worked out a set of percentage differences which are all percentage decrease. Should i express them as a negative percentage as -20%? I also need to plot them on a graph and am not sure whether to just use the percentage difference as it is, in which case i get a positive gradient, or include a negative axis and plot them in this way, in which case i would get a negative gradient. I think the slope of the curve will be the same either way so it might not matter!

Percentage change in completion rate 2003-02-21
From Remo:
In the year 2000 300 out of a possible 600 completed a phone survey for a total of 50% completion rate.

In the year 2001 20 out of 100 possible people completed the survey when it was re-done. This is a completion rate of 20%

To figure out the percentage change between the years can just use the difference between the percentage figures I already have? Or can I calculate it the same as you would for non-percentage numbers. For example you gave an example here of a salary increase from $20 to $95 being an increase of 375%.

Would I solve my problem the same way expect substituting my percentages (.5 and .2) in place of $20 and $95?

Averages of Averages 2002-12-21
From Amy:
If in the month of October the % of Payments Received was 80.74% and in November it decreased to 69.36%. Can you take the 80.74-69.36/69.36 to get the % of difference. In otherwords can you take the % of difference when the numbers you are comparing are %'s????

Can you also take an average of an average? For example, average number of payments received in October was 25.00%, average number of payments received November was 50.00%, and the average number of payments received in December was 15.00%. Do you average (25.00%, 50.00% and 15.00%) or do you have to go back to the numbers that calculated the averages. For example, October 25.00% was based on 25 payments being received out of a possible 100. So instead of taking the average of the averages, do you take the average payments and the average customers over the 3 months and calculate the average???

Percentage change 1999-12-08
From Michael Weinberg:
I am the Laboratory information system supervisor in a hospital. Our computer system calculates the change of specific results to monitor a patient's status. But there is a problem with the calculation in the base code of the program.
If one day the patient has a Blood count of 100 (P for Previous) then the next day the Blood count is 75 (C for current), the computer should calculate the change as -25% using the calculation |P-C|/P= D (D for Delta) and then check for positive or negative by the equation If P>C then D*-1 or If P The program is calculating using the equation: ((P/C)-1)*100 in the above situation this would calculate the Delta as 33.33333% Referenced in a Laboratory manual published before computers were used to calculate the delta changes.
