# Decrease by percentage

Microsoft Excel is used for various functions and purposes. You can also decrease an amount, figure, or number in the respective cell using a formula. However, you should be careful of the formula when using it. The following guideline describes calculating decrease by percentage using a step-to-step approach:

# Estimating a decrease in figure using percentage: Figure 1. Example of estimating and calculating a decrease by a percentage

## Formula

`=number*(1-percent)`

## Explanation

If you are required to use Microsoft Excel for decreasing a value of a figure using a certain percentage then, you can simply use the above-given formula, which would multiply the number with the given percentage. Next, -1 should be excluded from the value for estimating the desired figure.

## How the formula works:

In the example attached above, you can see that the active cell uses the given formula for making the calculations:

`=C4*(1-D4)`

Using this example, let’s proceed further with the explanation. Excel first estimates the outcomes which would be garnered using 1-, and it would result in (0.9). The value is simply multiplied by the value in C4 (80) for estimating the final outcome of 72.

= 80*(1-*0.10)

= 80*(0.9)

=72

You should be careful when subtracting the given percentage from 1, when it comes to devaluating a figure. If you miss this step then, you will get the figure represented by the percentage.

Using the formula and procedure given above, you can calculate a decrease by percentage in a given price or amount. You should be familiar with how the formula works in Excel. The formula is simple to use, and anyone can use it for calculating large-sized datasets for calculating decrease by percentage:

• You should be familiar with the price of the item. For instance, you can see groceries in B4 cell, which was purchased for \$80. Open an Excel Sheet, and enter the value in a cell of your choice. Figure 2. Enter the total Price

• Next, you should enter the discount rate in a cell block next to groceries’ total cost. In this case, the given discount rate (percentage) is 10%. You should specify the discount rate by adding % next to the figure. Have a look below: Figure 3. Enter the Discount Percentage

• Now, in the final cell, you will enter excel formula to get an original price from percentage discount. Use the following screenshot for help

Notes on using decrease by percentage feature:

• Specify the number of cell number for the product and cell number for discount rate in the formula bar.
• Look for any symbols in the cells which could disrupt the calculation process, and eliminate it accordingly
• You can simply enter the formula in the top cell of the list, and drag it all way down for calculating the rest of the products.
