Percentage change between two numbers A & B can be calculated as:
(B-A)/A * 100
For example, if a stock price increases in value from $123 to $145 the percentage increase is:
(145-123)/123 * 100 = 17.9%
Alternatively, if a stock price decreases in value from $145 to $123 the percentage decrease is:
(123-145)/145 * 100 = 15.2%
The technically correct answer to the scenario of $145 stock dropping to $123 is a -15.2% change in price. The original answer is semantically correct because the user calls out percentage "decrease", but you cannot have a drop in value and a positive % change outcome.

How do you calculate what percentage a number is out of another number?
To calculate that answer to "a is what percentage of b" divide a by b, then move the decimal point two places to the right. In more rigorous terms: divide a by b, then multiply by 100. But the answer is the same either way.
What percentage is 12 of 240?
To find the percentage a number is of a another number, divide the "is" number by the "of" number. Then, change the decimal into a percent. (Click on the link to learn how to change a decimal to a percent: http://wiki.answers.com/Q/How%20do%20change%20a%20decimal%20to%20percent)12/240 = 0.050.05 = 5%
How do you calculate a percentage change in excel if one number is negative?
To find the percentage change, you divide the change from initial to final by the absolute value of the initial value and then multiply by 100%. As an example: if the initial value is in cell A1 and the final value is in cell A2, the formula for percent change would be: =(A2-A1)/ABS(A1). You can EITHER multiply that value by 100 to get the percentage OR format the cell to display the number as a percentage. If the original number is negative and the final number is less (even more negative) - this makes the percentage change negative. If the original number is negative and the final number still negative but greater (closer to zero) then this would be an increase even though it would be less negative so the percent change would be positive. If the original number is negative and the final number zero or positive, this would still constitute an increase so the percentage change would be positive. If the initial number was positive and the final number negative, then this would be a pretty obvious decrease and the percentage change would be negative.

How do you figure what percent one number is of another number?
If you take '2' and '4', then 2 is 50% of 4. To calculate that, use (2/4)*100 to get the percentage. So to find out what percentage number 'x' is of number 'y', use (x/y)*100.
How do you calculate a percentage change from one number to anotherj?
You take the original number. You then work out by how much this number has changed (so if the new number is bigger subtract the original number from the new number and if it is smaller subtract the new number from the original). Now you divide the difference (how much the number has changed) by the original number and multiply the result by 100.An example:100 becomes 120.The number has changed by (120 - 100) 20. It has increased by 20.To calculate the percentage change we do:20 (the change) / 100 (the original number) and then multiply by 100 (to turn it in to a percentage rather than a fraction).20/100 * 100 = 20%So, in this example, the number has increased by 20%.
How do you change the number 4 into percent?
