Excel is a powerful tool for performing complex calculations and analyzing data. One common task in Excel is calculating percent increases, which can be useful for tracking trends or comparing data over time. In this tutorial, we will cover how to calculate percent increases in Excel using several different methods.

Method 1: Simple Percent Increase Formula

The simplest way to calculate a percent increase in Excel is to use the following formula:

= (New Value – Old Value) / Old Value

This formula calculates the percentage difference between two values. For example, if you have an old value of 100 and a new value of 120, the percent increase would be:

= (120 – 100) / 100 = 0.2 or 20%

To use this formula in Excel, simply enter the values into two cells and then enter the formula in a third cell. For example, you could enter the old value in cell A1, the new value in cell B1, and the formula in cell C1.

Method 2: Percent Increase Function

Excel also has a built-in function for calculating percent increases called “PERCENTAGE.INCREASE”. To use this function, you need to provide the old value and the new value as arguments. For example, if you have an old value of 100 in cell A1 and a new value of 120 in cell B1, you could use the following formula:

=PERCENTAGE.INCREASE(A1, B1)

This formula would return the percent increase as a decimal value (0.2 in this case). To format the result as a percentage, you can multiply it by 100 and apply the Percentage format to the cell.

Method 3: Percentage Change Function

Another built-in function for calculating percent increases in Excel is “PERCENTAGE.CHANGE”. This function works similar to the previous function, but it can handle negative values as well. To use this function, you need to provide the old value and the new value as arguments. For example, if you have an old value of 100 in cell A1 and a new value of 80 in cell B1, you could use the following formula:

=PERCENTAGE.CHANGE(A1, B1)

This formula would return the percent decrease as a decimal value (-0.2 in this case). To format the result as a percentage, you can multiply it by 100 and apply the Percentage format to the cell.

Method 4: Percentage Difference Formula

Another formula that can be used to calculate percent increases in Excel is the Percentage Difference formula. This formula is similar to the simple percent increase formula, but it is more flexible and can be used to calculate percentage differences between any two values, not just increases. The formula is:

= ABS(New Value – Old Value) / ((New Value + Old Value) / 2)

To use this formula, you need to enter the old value and new value into two cells and then enter the formula in a third cell. For example, if you have an old value of 100 in cell A1 and a new value of 120 in cell B1, you could use the following formula:

= ABS(B1 – A1) / ((B1 + A1) / 2)

This formula would return the percent increase as a decimal value (0.1667 or 16.67% in this case).

Conclusion

Calculating percent increases in Excel is a common task that can be accomplished using several different methods. Whether you prefer to use a simple formula or a built-in function, Excel has many tools available to help you calculate percent increases quickly and easily. By using these methods, you can track trends, analyze data, and make informed decisions based on your findings.
