In an excel sheet, calculating the chain is a measure of relative changes in data, often used to compare data changes over adjacent time periods or periods. Here are the general formulas and steps for calculating the ring comparison:
Let's say you have two columns of data: one for the current period (e.g., this month, this quarter) and one for the previous period (e.g., last month, last quarter).
1.Create a new column
First, select a blank cell in Excel that will be used to calculate the ring comparison. Then enter the following formula:
Current Period Value - Previous Period Value) Previous Period Value.
In other words, the formula is actually subtracting the value of the previous period from the value of the current period and dividing the value of the previous period. This will give a small value that represents the percentage of relative change.
2.Copy the formula
Apply this formula to the corresponding cells of other rows. You can copy the formula by dragging the fill handle (located in the bottom right corner of the cell) or by using the shortcut keys (Ctrl + D).
3.Formatted as a percentage
Since we want to present the chain data as a percentage, we need to format the new column as a percentage. Select the new column, right-click and select "Format Cell". In the dialog box that pops up, select the Percentage category and set the number of decimal places you want.
After completing the above steps, Excel will calculate and display the chain data for each row to reflect the relative change between the current period and the previous period.
It is important to note that the values used in the formula will vary depending on your actual data range and layout. Please make sure to replace the correct cell reference when you enter the formula, and adjust it according to the actual situation of the data.
In addition, if the data has missing or zero values, it can lead to incorrect or invalid ring calculations. When processing this data, check and take appropriate measures, such as eliminating missing values or making conditional judgments in formulas, to avoid calculation errors.
