VIDEO: Calculate the deviation in percent - this is how you proceed

How to find out the difference in percent

You can calculate the percentage variance if there are two different values ​​for a specific key figure. This can be, for example, an actual value and a target or average value.

1. First, calculate the absolute deviation by subtracting the smaller from the larger value.
2. Think about what value you consider to be the core value. The basic value is always the value from which the other value deviates. If you want to calculate the percentage deviation of an actual value from a target value, the target value corresponds to the basic value.
3. You can calculate the percentage deviation by multiplying the absolute deviation by 100 and dividing by the basic value.
4. The percentage deviation does not initially say anything about which value is greater. If the actual value is smaller than the setpoint, it is a negative deviation, conversely it is a positive one.

An example of calculating the percentage deviation

The average monthly turnover of a company is 250,000 euros. In April the company achieved sales of 230,000 euros and in May 270,000 euros.

1. The average monthly turnover of 250,000 euros corresponds to the basic value, from which the other two values ​​differ.
2. In both April and May, the absolute deviation is 20,000 euros. That is the difference between the average sales and the actual sales.
3. Multiply 20,000 euros by 100 and divide this value by 250,000 euros. You will get a deviation of 8 percent.
4. That means actual sales were up 8 percent from both April and May Average sales deviate, except that April is negative and May is positive Deviation acts.
