how to subtract a column in excel

Performing column subtraction in Excel is pretty straightforward and can save tons of time. First, you select the cell where you want the result. Second, you write a formula that subtracts one column from another. Finally, you drag this formula down through the cells to apply it across multiple rows. This summary should give you a good idea of what to expect.

## How to subtract a column in Excel

Alright, let’s dive into the nitty-gritty details of how to subtract one column from another in Excel. By following these steps, you’ll be able to complete this task with ease.

### Step 1: Select the Result Cell

First, select the cell where you want the result of your subtraction to appear.

When you click on the cell, it becomes the active cell. This is where your formula will live, and where the subtraction result will show up.

### Step 2: Write the Formula

Next, enter the formula to subtract one column from another. Start by typing an equal sign (=), then click on the first cell you want to subtract from. Type a minus sign (-), and finally click on the cell you want to subtract.

For example, if you’re subtracting cell B1 from cell A1, your formula will look like this: `=A1-B1`. Press Enter to see the result.

### Step 3: Apply the Formula to Multiple Cells

Now, click on the cell with your formula. You’ll see a small square at the bottom-right corner of the cell. Click and drag this square down to apply the formula to other cells in the column.

Dragging the formula down copies it to the other cells. Each cell will subtract the corresponding cells in columns A and B.

### Step 4: Check Your Results

Make sure to double-check your results to ensure the subtraction has been done correctly.

It’s always good practice to verify a few key cells to make sure the formula has been copied correctly and the results are accurate.

### Step 5: Save Your Work

Finally, don’t forget to save your Excel file to keep all your hard work intact.

You can do this by clicking "File" in the top-left corner, then selecting "Save" or "Save As" to save your Excel sheet.

After you’re done with these steps, you’ll see the results of your subtraction in the cells you dragged the formula through. Excel will continue to show the updated subtraction results if you change any of the original numbers. Pretty cool, right?
