  • Format as percentage
  • Interpret result
  • Use in formulas

With these steps, you can easily calculate the percentage change in Excel and use it for various purposes.

Input old value

The first step in calculating the percentage change in Excel is to input the old value. This is the value from which you want to measure the change. It can be any numerical value, such as a sales figure, a stock price, or a population count.

To input the old value, simply enter it into a cell in the Excel worksheet. Make sure that the cell is formatted as a number, not as text. You can do this by selecting the cell and clicking on the "Number" button in the "Number" group on the "Home" tab. Alternatively, you can press Ctrl+1 to open the "Format Cells" dialog box and select the "Number" category.

Once you have entered the old value, you can proceed to the next step, which is to input the new value.

Tips for inputting the old value:

  • Make sure that the old value is accurate and up-to-date.
  • If the old value is a whole number, you can enter it without any decimal places. However, if the old value is a decimal number, you must enter it with the correct number of decimal places.
  • If the old value is negative, you must enter it with a minus sign (-).

After you have inputted the old value and the new value, you can proceed to the next step, which is to calculate the difference between the two values.

Once you have calculated the difference between the old value and the new value, you can proceed to the next step, which is to divide the difference by the old value.

Input new value

The second step in calculating the percentage change in Excel is to input the new value. This is the value that you want to compare to the old value in order to determine the change.

To input the new value, simply enter it into a cell in the Excel worksheet, next to the old value. Make sure that the cell is also formatted as a number, not as text.

Once you have entered the new value, you can proceed to the next step, which is to calculate the difference between the two values.

Tips for inputting the new value:

  • Make sure that the new value is accurate and up-to-date.
  • If the new value is a whole number, you can enter it without any decimal places. However, if the new value is a decimal number, you must enter it with the correct number of decimal places.
  • If the new value is negative, you must enter it with a minus sign (-).

After you have inputted the new value, you can proceed to the next step, which is to calculate the difference between the two values.

Once you have calculated the difference between the old value and the new value, you can proceed to the next step, which is to divide the difference by the old value.

Calculate difference

The third step in calculating the percentage change in Excel is to calculate the difference between the old value and the new value. This can be done using the following formula:

Difference = New Value - Old Value

To calculate the difference in Excel, simply enter the following formula into a cell in the Excel worksheet:

=B2-A2

In this formula, A2 is the cell that contains the old value and B2 is the cell that contains the new value.

Once you have entered the formula, press Enter. The difference between the old value and the new value will be displayed in the cell.

Tips for calculating the difference:

  • Make sure that you are using the correct formula.
  • Make sure that you are referencing the correct cells.
  • If the difference is a negative number, it means that the new value is less than the old value.
  • If the difference is a positive number, it means that the new value is greater than the old value.

After you have calculated the difference between the old value and the new value, you can proceed to the next step, which is to divide the difference by the old value.

Once you have divided the difference by the old value, you can proceed to the next step, which is to multiply the result by 100.

Divide by old value

The fourth step in calculating the percentage change in Excel is to divide the difference between the old value and the new value by the old value. This will give you the percentage change as a decimal number.

  • Divide the difference by the old value.

    To do this, simply enter the following formula into a cell in the Excel worksheet:

    =C2/A2

    In this formula, A2 is the cell that contains the old value and C2 is the cell that contains the difference between the old value and the new value.

  • Format the result as a percentage.

    Once you have divided the difference by the old value, you need to format the result as a percentage. To do this, select the cell that contains the result and click on the "Percentage" button in the "Number" group on the "Home" tab. Alternatively, you can press Ctrl+Shift+%. This will format the result as a percentage with two decimal places.

  • Interpret the result.

    The result of the division is the percentage change between the old value and the new value. If the result is a positive number, it means that the new value is greater than the old value and the change is an increase. If the result is a negative number, it means that the new value is less than the old value and the change is a decrease.

  • Use the result in formulas.

    The result of the percentage change calculation can be used in other formulas in Excel. For example, you could use it to calculate the total amount of change or the average rate of change.

Once you have divided the difference by the old value and formatted the result as a percentage, you can proceed to the next step, which is to interpret the result.

Multiply by 100

The fifth step in calculating the percentage change in Excel is to multiply the result of the division by 100. This will convert the decimal number to a percentage.

  • Multiply the result of the division by 100.

    To do this, simply enter the following formula into a cell in the Excel worksheet:

    =D2*100

    In this formula, D2 is the cell that contains the result of the division.

  • Format the result as a percentage.

    Once you have multiplied the result of the division by 100, you need to format the result as a percentage. To do this, select the cell that contains the result and click on the "Percentage" button in the "Number" group on the "Home" tab. Alternatively, you can press Ctrl+Shift+%. This will format the result as a percentage with two decimal places.

  • Interpret the result.

    The result of the multiplication is the percentage change between the old value and the new value. If the result is a positive number, it means that the new value is greater than the old value and the change is an increase. If the result is a negative number, it means that the new value is less than the old value and the change is a decrease.

  • Use the result in formulas.

    The result of the percentage change calculation can be used in other formulas in Excel. For example, you could use it to calculate the total amount of change or the average rate of change.
