## 2 Issues with Solutions When Excel Iterative Calculation Is Not Working

Here, I will describe** 2 **suitable solutions for why Excel **Iterative** calculation not working. In addition, for your better understanding, I’m going to use the following dataset. Where I want to sum up the **SIN function** and **COS function** with the same value of **X** using **the SUM function**.

Furthermore, I repeat the whole process for the output from the **E5** cell. At this time, I want the value of **X** for which the summation of the **Sin** and **Cos** function will be very close to the **previous** one. Basically, which is an** Iterative** process. Where the result will be converging.

### 1. By Changing Manual Calculation to Automatic

Sometimes, you try the **Fill Handle** icon for **Iterative** calculation, but you may see that all the values are remaining the same. Which means the formula is not responding to the rest of the cells.

Actually, this is happening because you may keep on the** Manual Calculations option** in the Excel workbook. Furthermore, below, I have attached an image of it.

As a result, you will see that there is no change in the calculation. Which means your calculation remains unoperated.

Now, let’s talk about the solution.

**Solution:**

- Firstly, from the
**Formulas**tab >> go to**Calculation Options**. - Secondly, tick mark on the
**Automatic**option.

Finally, you will see that your calculation is auto-updated. Furthermore, the result from **B17** is converging.

### 2. Enable Iterative Calculation from Excel Options

There is a built-in program in Excel to do the **Iterative calculation**. Moreover, through this, you don’t need to do the Iteration by dragging the **Fill Handle** icon. Here, by enabling the **Iterative calculation **feature you can just get your iterated result at a glance.

So, you should make sure that the** Iterative calculation **feature enables or not.

At this time, a new window will appear.

- Then, go to the
**Options**.

As a result, a new dialog box named **Excel Options** will appear.

- After that, from the
**Formulas**menu >> tick mark on**Enable iterative calculation.** - Then, press
**OK**.

So, by doing this now you can use the **Excel iterative calculation **against not working the iterative calculation.

- Then, write the added value in the
**B5**cell.

- After pressing
**ENTER**, you will see the iterated values at a glance.

## How to Fix When Circular Reference Is Not Working in Excel

There is a term in Excel named **Circular reference**. Here, the** circular reference** is a formula that returns the same or another cell numerous times in its sequence of calculations, resulting in an** infinite loop** that severely slows down your spreadsheet.

Furthermore, to illustrate** circular reference** more clearly I will use the following dataset. The dataset consists of **Sales** and **Profit** for some customers. Suppose, I need to calculate the total amount of sales in cell** C12**.

Now, If you accidentally select the cell range** (C5:C12)** you might not get the result that you are expecting. Basically, *when you include this C12 cell in the function itself, then it is called a circular reference*.

Now, let’s take a look at the steps how to solve this problem.

**Solution:**

- Firstly, follow the steps of
**method-2**and open the dialogue box named**Excel Options**. - Secondly, from that box select
**Formulas**and check the option**Enable iterative calculation.** - Thirdly, set the value
**1**for**Maximum iterations**. Here, the value**1**indicates that the formula will iterate only once through the cells**C5 to C11**. - Lastly, press
**OK**.

Finally, you will not get any circular reference errors in cell **C12**. It returns the total sales amount in cell** C12**.
