Using the SUM Function in Excel

The SUM function in Excel helps you quickly add up a range of numbers. It’s a simple tool but can save you a lot of time. In this article, you’ll learn how to use the SUM function step by step. By the end, you’ll be able to total any range of numbers in your Excel spreadsheet with ease.

## Step by Step Tutorial: Using the SUM Function in Excel

### Step 1: Open Excel and Select Your Cells

Open Excel and select the cells that you want to add together.

Simply click and drag your mouse over the cells you want to highlight. If the cells are not next to each other, hold down the CTRL key while clicking each cell.

Go to the Formula tab in the Excel toolbar.

This tab is where all your formula tools are located, making it easy to find the SUM function.

The AutoSum button is usually labeled with the Greek letter Sigma (Σ). Clicking it will automatically insert the SUM function into your selected cell.

### Step 4: Press Enter

Press the Enter key to complete the formula.

Once you press Enter, Excel will calculate and display the total of the selected cells.

### Step 5: Review Your Results

Check the result to make sure it’s correct.

If the total of your cells is not what you expected, double-check that you selected the correct cells and used the right function.

After completing these steps, you’ll have a total for the selected cells in your Excel sheet. This is a great way to quickly add numbers without having to do it manually.

## Tips for Using the SUM Function in Excel

• Always double-check your cell selection before applying the SUM function to avoid errors.
• You can use the SUM function for non-continuous cells by holding down the CTRL key while selecting.
• If you frequently use the SUM function, memorize the keyboard shortcut: ALT + =.
• You can write the SUM formula manually by typing =SUM(A1:A10) directly into the cell.

### What if I only want to sum certain cells?

Hold down the CTRL key while selecting each cell you want to include in the sum.

### Can I sum cells from different sheets?

Yes, you can. Use the formula =SUM(Sheet1!A1, Sheet2!B1) to sum cells from different sheets.

### How do I sum an entire column?

Click on the letter of the column you wish to sum, then go to the AutoSum button to quickly sum all cells in that column.

### What if I need to sum filtered cells?

Use the SUBTOTAL function instead of SUM to sum only visible (filtered) cells.

### Can I use SUM for text values?

No, the SUM function only works with numerical values. Text values will be ignored in the calculation.
