- Define the variables with semicolons (;) after each one.
- End the function with a closing parenthesis ().

With **LET**, you can set variables for your Excel formulas, making them easier to read and understand. Moreover, it reduces redundant calculations.

For example, to calculate total cost of an order, you can define variables for **quantity** and **unit price**. This way, if either of these changes later, you only need to modify the corresponding variable – instead of reworking the entire formula.

In investment analysis, you can use LET to define inputs like **interest** or **growth rate** as variables with descriptive names. This makes the financial models more readable and understandable.

### Applying the LET Function in Excel

Type **=LET** into an empty cell to begin.

Then, define the variables you want to use – for example: **=LET(x, 7, y, 6)**.

After that, enter your formula using the defined variables: **=LET(x, 7, y, 6, x+y)** and press enter. The answer will appear.

Using **LET** in formulas can save time and make complex calculations easier.

It’s important to remember that variables are only temporary and vanish when the formula is finished or deleted.

Also, **LET** can only work with dynamic arrays or spill ranges, making it great for large datasets.

I used **LET** in a project with a large dataset and it saved me hours of work.

Let’s learn more about applying the **LET Function in Excel** with examples and use cases in the next section.
