How To Calculate Percent Relative Range
A range is an interval that defines the minimum and maximum values for any set of numbers or for the variation of a particular variable — a stock price on the market, for example. The percent relative range refers to the percentage ratio of the range to the average value in the set.
Step 1
Sum up the maximum and minimum values in the range. For example, if the stock price changes in the range from $34.67 to $41.12 then $34.68 + $41.12 = $75.80.
Step 2
Divide the sum by two to calculate the average value. In the example, the average price is $75.80 /2 = $37.90.
Step 3
Subtract the minimum value from maximum one to calculate the range. In this example, the range is $41.12 – $34.68 = $6.44.
Step 4
Divide the range by the average value, and then multiply the result by 100 to calculate the relative percent range. In this example, the relative percent range is ($6.44 / $37.90) x 100 = 16.99 percent.
