# How to Allow Circular Reference in Excel?

Are you working with Excel and have hit a roadblock due to circular references? Don’t worry! In this article, we will provide a step-by-step guide to help you understand how to allow circular references in Excel. We’ll cover the different methods used to enable circular references and how to ensure that they are properly managed. So, if you’re looking to learn more about Excel and circular references, keep reading! ## What is a Circular Reference in Excel?

A circular reference in Excel occurs when a formula contains a cell reference that refers back to itself, or to another cell referencing the original cell. This can cause an infinite loop that Excel can’t solve. For example, if cell A1 contains the formula “=A1+1”, then the formula has a circular reference.

Circular references can cause unexpected results in your calculations and should generally be avoided. However, there are times when you may need to use a circular reference. For example, if you are creating a budget that calculates the total amount of money spent, you may need to use a circular reference to calculate the amount of money remaining.

## How to Allow Circular Reference in Excel?

To enable a circular reference in Excel, first click on the “File” tab and then click on “Options”. Next, click on the “Advanced” tab and then scroll down to the “Formulas” section. Finally, check the box labeled “Enable iterative calculation” and then click “OK”.

This setting will allow Excel to use circular references and will also enable a new feature called “iterative calculation”. Iterative calculation allows you to specify the maximum number of iterations (calculations) that Excel will use to solve a circular reference. By default, this is set to 100.

### What is Iterative Calculation?

Iterative calculation is a feature in Excel that allows you to specify the maximum number of iterations (calculations) that Excel will use to solve a circular reference. By default, this is set to 100. This means that Excel will repeat the calculation up to 100 times to try and find a result. If it still can’t find a result after 100 iterations, it will display a warning message.

If you are using a circular reference in your spreadsheet, you may want to increase the number of iterations that Excel uses to calculate the result. To do this, click on the “File” tab and then click on “Options”. Next, click on the “Advanced” tab and scroll down to the “Formulas” section. Finally, increase the “Maximum Iterations” value and then click “OK”.

### What are the Benefits of Iterative Calculation?

Iterative calculation can be useful when you are using circular references in your spreadsheet. It allows you to specify the maximum number of iterations that Excel will use to calculate the result, which can be helpful if you are dealing with a complex calculation.

In addition, iterative calculation can help to improve the accuracy of your results. By increasing the number of iterations, you can make sure that Excel is using the most accurate calculation possible.

### What are the Drawbacks of Iterative Calculation?

Using iterative calculation can have some drawbacks. For example, increasing the number of iterations can slow down the calculation process and cause Excel to use more resources. Additionally, if the number of iterations is set too high, it can cause Excel to become unresponsive or even crash.

In addition, iterative calculation can lead to errors if the maximum number of iterations is set too low. For example, if the number of iterations is set to 10 but the calculation requires 12 iterations to be accurate, then the result will be inaccurate.

## When to Use a Circular Reference?

Circular references should generally be avoided, as they can cause unexpected results in your calculations. However, there are certain circumstances in which you may need to use a circular reference. For example, if you are creating a budget that calculates the total amount of money spent, you may need to use a circular reference to calculate the amount of money remaining.

In these cases, it is important to use iterative calculation to ensure that the result is as accurate as possible. This can help to minimize errors and ensure that your calculations are accurate.

### How to Minimize Errors?

When using a circular reference, it is important to minimize errors. To do this, you should always use iterative calculation and increase the maximum number of iterations if necessary. Additionally, you should review your calculations to ensure that they are accurate and make adjustments as needed.

Finally, it is important to test your calculations to ensure that they are working as expected. This can help to identify any errors and ensure that your circular reference is working as intended.

### Conclusion

Circular references should generally be avoided, as they can cause unexpected results in your calculations. However, there may be times when you need to use a circular reference in your spreadsheet. In these cases, it is important to use iterative calculation to ensure that the result is as accurate as possible. Additionally, you should review your calculations, test them, and make adjustments as needed to minimize errors.

## Related FAQ

### Q1. What is a Circular Reference in Excel?

A circular reference in Excel occurs when a formula references itself, either directly or indirectly. This creates a circular chain of dependencies, where a change in one cell causes a chain reaction of updates to other cells. This can cause Excel to get stuck in an endless loop and become unresponsive, so it’s important to understand how to manage and even allow circular references in Excel.

### Q2. What are the Benefits of Allowing Circular Reference in Excel?

Allowing circular references in Excel can be beneficial in some cases, such as when creating a budget worksheet. When calculating the budget, you may need to use the total of the budget in other calculations. Allowing a circular reference would enable you to use the same cell for both calculations without causing an error. Additionally, circular references can be used to model complex problems that involve multiple variables that are all dependent on each other.

### Q3. How to Enable Circular Reference in Excel?

Circular references can be enabled in Excel by going to the File menu and selecting Options. Under the Formulas tab, there is an option to Enable Iterative Calculation. This will allow Excel to calculate circular references. However, it’s important to note that if the circular references involve large amounts of data, they can take a long time to calculate, so it’s best to check the calculation time before enabling it.

### Q4. How to Locate Circular Reference in Excel?

Once a circular reference has been enabled in Excel, the next step is to locate the circular reference. This can be done by selecting the Formulas tab and then clicking on the Error Checking button. This will bring up a list of any errors that are present in the worksheet, including circular references.

### Q5. How to Troubleshoot and Avoid Circular Reference in Excel?

Once a circular reference has been identified, it’s important to troubleshoot it to ensure that the worksheet is functioning properly. This can be done by tracing the circular references to see where the loop is occurring and then making changes to break the loop. Additionally, it’s important to understand the data and be aware of the relationships between cells to avoid creating circular references in the first place.

### Q6. What are the Limitations of Using Circular Reference in Excel?

Excel’s ability to handle circular references has its limitations. It can take a long time to calculate circular references when dealing with large amounts of data. Additionally, circular references can lead to inaccurate results if the data is not consistent or if the relationships between cells are not properly understood. It’s also important to be aware that Excel may become unresponsive if the circular references cause an endless loop.

### Circular Reference – Fixing Circular Reference in Excel 2013

In conclusion, allowing circular reference in Excel can be beneficial when trying to solve complex equations. By utilizing the tools available such as the Enable Iterative Calculation option and the Circular Reference Warning, it is possible to safely use circular references in Excel. However, with any form of recursive calculation, it is important to be mindful of the potential for errors and to use proper caution when using this feature. With the right approach, circular references can be a powerful tool that unlocks a new level of problem-solving in Excel.
