Calculate Development Fee from Two Knowledge Factors
The expansion charge, also called the proportion change, is a invaluable metric for quantifying the magnitude and path of change over time. In Excel, calculating the expansion charge between two knowledge factors is an easy course of that may be carried out utilizing primary formulation.
Steps for Calculating Development Fee from Two Knowledge Factors
-
Set up your knowledge: Be certain that your knowledge is organized chronologically, with the sooner worth listed first.
-
Decide the change in worth: Subtract the sooner worth from the later worth. This calculation yields absolutely the change in worth.
-
Calculate the expansion charge: Divide absolutely the change in worth by the sooner worth. The result’s the expansion charge, expressed as a decimal.
To calculate the proportion development charge, multiply the expansion charge by 100 and categorical the end result as a share.
As an example, if the sooner worth is 10 and the later worth is 15, absolutely the change in worth is 5. The expansion charge is 5 divided by 10, which is 0.5, or 50% when expressed as a share.
| Preliminary Worth | Remaining Worth | Absolute Change | Development Fee | Share Development |
|---|---|---|---|---|
| 10 | 15 | 5 | 0.5 | 50% |
Decide Development Fee from a Sequence of Knowledge
Step 1: Convert the info to percentages
To calculate the expansion charge, we have to categorical the info as a share. To do that, subtract the earlier worth from the present worth, after which divide the distinction by the earlier worth. For instance, if the info is 10, 20, 30, 40, then the proportion development charge for the second yr could be (20 – 10) / 10 = 100%.
The share change for every interval will be calculated utilizing the next system:
Share Change = [(Current Value – Previous Value) / Previous Value] x 100
Step 2: Calculate the typical share change
As soon as now we have transformed the info to percentages, we are able to calculate the typical share change. To do that, we merely add up the entire share modifications and divide by the variety of durations. For instance, if the proportion modifications are 100%, 50%, and 25%, then the typical share change could be (100% + 50% + 25%) / 3 = 58.33%.
The common share change represents the general development charge of the info over the desired interval.
Step 3: Categorical the expansion charge as a decimal
Lastly, we have to categorical the expansion charge as a decimal. To do that, we merely divide the typical share change by 100. For instance, if the typical share change is 58.33%, then the expansion charge as a decimal could be 58.33% / 100 = 0.5833 or 58.33%.
