Calculating percentages The basic formula for calculating a percentage is =part/total. Say you want to reduce a particular amount by 25%, like when you're trying to apply a discount. Here, the formula will be: =Price*1-Discount %. (Think of the “1” as a stand-in for 100%.)

To the find the percent increase, first subtract the initial value from the final value. Then take the difference and divide it by the initial value. Finally, multiply this number by 100% to convert the number to a percentage. This final result will represent the percent increase between the two values.

First: work out the difference (increase) between the two numbers you are comparing. Then: divide the increase by the original number and multiply the answer by 100. % increase = Increase ÷ Original Number × 100. If your answer is a negative number, then this is a percentage decrease.

First Step: find the difference between two percentages, in this case, it's 15% - 5% = 10%. Second: Take 10 percent, and divide by 2nd percentage: 10/5 = 2. Now multiply this number by 100: 2*100 = 200%.

Thus, a product that normally costs $2 with a 5 percent discount will cost you $1.90, and you saved $0.10. You can also calculate how much you save by simply moving the period in 5.00 percent two spaces to the left, and then multiply the result by $2 as follows: $2 x . 05 = $0.10 savings.

Final Price: Thus, a product that normally costs $10 with a 5 percent discount will cost you $9.50, and you saved $0.50. You can also calculate how much you save by simply moving the period in 5.00 percent two spaces to the left, and then multiply the result by $10 as follows: $10 x . 05 = $0.50 savings.

How do you work out the percentage of something? To calculate what percentage the number A is of B, you can simply divide A by B and then multiply by 100 or simply move the decimal place to the right twice. So for example the percentage 2 is of 4 is 2/4*100 = 0.5*100 = 50%.

The percentage difference between two values is calculated by dividing the absolute value of the difference between two numbers by the average of those two numbers. Multiplying the result by 100 will yield the solution in percent, rather than decimal form.
