## Step-by-Step Tutorial on How to Auto Calculate in Excel

In this tutorial, we’ll walk you through setting up auto calculations in Excel using basic functions like SUM, AVERAGE, and more. Follow these steps to make your Excel sheets do the math for you.

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

Start by opening Excel and selecting the cells where you want the calculations to occur.

Choosing the right cells is crucial. Make sure to click and drag to highlight the range of cells you want to include in your calculation.

### Step 2: Choose a Function from the Formulas Tab

Go to the "Formulas" tab on the top ribbon and pick a function like SUM or AVERAGE.

The "Formulas" tab has a variety of functions grouped into categories. Click on a category to see the available functions. For instance, if you want to sum numbers, click on the Math & Trig category and select SUM.

### Step 3: Enter Your Data

Pressing Enter finalizes your formula. If you’ve done everything correctly, you should see the result of your calculation in the cell where you entered the formula.

### Step 5: Observe the Automatic Calculation

Notice that every time you change the data in your selected cells, the result updates automatically.

This dynamic updating is what makes auto calculating so powerful. Change any number in the range, and Excel will instantly recalculate the result.

After completing these steps, your Excel sheet will automatically calculate the results based on the data you enter. It’s like having a math whiz on standby, ready to crunch the numbers for you.
