So, How to fix the Excel formula not calculating?

In this guide, I will walk you through a step-by-step process to identify and rectify if Excel formula is not working.

What Causes Excel Formulas Not Calculating?

There can be many issues that can cause Excel to not calculate formula. Here are some major problems.

1. Text Formatting Interference

Problem: Formulas display as text instead of providing calculated values.

Cause: Cells are formatted as 'text' instead of the 'General' type. It can happen due to previous text formatting or inheriting formatting from adjacent columns.

1. Formula Evaluation Troubles

Problem: Formulas yield unexpected results.

Cause: Complex formulas can contain errors that are hard to spot at first glance.

1. Gremlins in your Formulas

Problem: Formulas don't work as intended.

Cause: Errors such as mismatched parentheses, incorrect cell references, or improper use of functions/operators can disrupt calculations.

1. Calculation Automatic Update

Problem: Formulas don't update automatically.

Cause: Excel's calculation settings might be manual, preventing automatic updates.

1. Circular Reference Quandary

Problem: Calculations go awry.

Cause: Circular references, where a formula refers to the cell containing the formula itself, can lead to chaos.

1. Data Type Dilemmas

Problem: Formulas behave unexpectedly with different data types.

Cause: Performing operations on incompatible data types can lead to unexpected outcomes.

1. Cell and Sheet Protection Issues

Problem: Formulas aren't calculated due to protection settings.

Cause: Protected cells can prevent formulas from updating or being edited.

1. External Reference Puzzles

Problem: Formulas referencing external cells don't give desired results.

Cause: Incorrect or inaccessible external references can disrupt calculations.

1. Add-In Malfunctions

Problem: Formulas misbehave due to third-party add-ins.

Cause: Excel's default calculation order might not align with your expectations.

How to Fix Excel Formulas Not Calculating?

Now that you know the most common causes of why your Excel formula is not working, let’s explore the solution to each error.

1. Text Formatting Interference

When cells are set to 'text' format instead of the more versatile 'General' type, Excel interprets everything, including formulas, as text. This can happen if you've previously applied text formatting to the cell or when a new column inherits formatting from an adjacent text-formatted column.

Step 1: Check Cell Formatting

1. Right-click on the cell displaying the formula as text.

2. Select "Format Cells" from the context menu.

3. Choose the "Number" tab.

4. Select "General" or the appropriate number format.

5. Click "OK" to apply the new formatting.

Step 2: Clear Formatting

1. Right-click the cell with the text-formatted formula.

2. Choose "Format Cells."

3. Go to the "Number" tab and select "General."

4. Click "OK" to remove text formatting.

Step 3: Fix Adjacent Column Formatting

1. Identify adjacent columns with text formatting.

2. Right-click the column letter and select "Insert."

3. Copy data from the problematic column to the new column.

4. Delete the original column if unnecessary.

2. Formula Evaluation Troubles

Formula evaluation can be challenging, but don’t fret; Excel offers a built-in tool to evaluate complex formulas and perform seamless calculations.

Step 1: Use Formula Evaluation

1. Select the cell containing the formula you want to evaluate.

2. Go to the "Formulas" tab in the Excel ribbon.

3. Click "Evaluate Formula" in the "Formula Auditing" group.

4. 

5. Click "Evaluate" to step through the formula's calculations.

1. Examine each step carefully to identify errors or unexpected behaviour. For Example, in this formula, there is a constant i-e, in this case, a “space” before = sign.

Step 2: Check Nested Functions

1. Break down complex formulas into smaller parts.

2. Evaluate each nested function individually to identify errors.

3. Make sure the inputs for each function are correct.

Step 3: Review Cell References

1. Verify that all cell references in the formula are accurate.

2. Double-check for missing or extra dollar signs ($) for absolute references.

3. Rectifying Formula Errors in Excel

Excel uses a specific order while calculating. It depends on the correct use of parentheses and operators. If you have jumbled the operators and parentheses, you might get inaccurate calculations, or Excel will fail to execute the formula.

Step 1: Parentheses and Operators

1. Examine the formula for mismatched parentheses.

2. Ensure correct use of operators (+, -, *, /).

Step 2: Function Syntax

1. Review each function's syntax in the formula.

2. Check the order and type of arguments.

Step 3: Error Checking

1. Use Excel's error-checking feature.

2. Click the cell with the error indicator for solutions.

4. Fixing Calculation Issues in Excel Formulas

Sometimes, calculations can be set to manual mode, causing formulas not to update automatically. Go to the "Formulas" tab and ensure that "Calculation Options" is set to "Automatic." If your formula is not updating automatically, follow these steps.

Step 1: Automatic Calculation

1. Go to the "Formulas" tab.

2. Click "Calculation Options" and select "Automatic."

   Step 2: Recalculate Worksheet

3. Press "F9" to recalculate the entire worksheet.

Step 3: Recalculate Specific Cells

1. Select the specific cell(s) to recalculate.

2. Press "Shift + F9" for selected cells.

5. Circular Reference Quandary

Follow these steps if you have circular references hindering Excel to calculate formulas.

Step 1: Identify Circular References

1. Look for circular reference warning messages.

2. Click "OK" to close the warning and locate the cell causing the issue.

Step 2: Resolve Circular References

1. Edit the formula in the circular reference cell to remove the circular reference.

2. If necessary, restructure your calculations to avoid circular references.

Step 3: Verify Calculation Order

1. Go to the "Formulas" tab and click "Calculation Options."

2. Choose "Manual" calculation mode temporarily.

3. Press "F9" to recalculate the worksheet manually.

4. Switch back to "Automatic" calculation mode.

6. Cell shows the formula instead of the result.

Often, a Cell contains the formula, but instead of calculating results, it shows the formula as a text. This issue commonly arises when the cells containing formulas are set to the 'text' formatting instead of the 'General' type.

This situation can occur due to either of the following reasons:

1. Text formatting has been applied to the cell at some point.

2. When you insert a new column next to an existing column with text formatting, the new column inherits the formatting of the adjacent column.

3. You have added an apostrophe or space before the = sign-in formula.

When this kind of formatting is applied, Excel treats any input in the affected cells (including formulas) as text, leading to the display of formula text instead of calculated values.

7.Formulas Not Calculating Due to Protection

Protection settings can potentially cause Excel not to calculate formulas. Protected cells, though crucial for data safety, protected cells can obstruct formula updates and edits, disrupting your workflow.

Step 1: Identify Protection Settings

1. Go to the "Review" tab.

2. Click "Protect Sheet" to view settings.

Step 2: Adjust Protection Settings

1. Uncheck options limiting cell edits or formatting.

2. Preserve data integrity while enabling necessary changes.

Step 3: Balance Security and Access

1. Assess required worksheet access levels.

2. Apply passwords for sensitive data if needed.

Strike a balance between protection and formula prowess. Your spreadsheets will maintain security by fine-tuning settings while allowing formulas to work seamlessly.

8.Order Of Operations

The order of operations is often remembered using the acronym PEMDAS, which stands for Parentheses, Exponents, Multiplication and Division (from left to right), and Addition and Subtraction (from left to right).

Here's a breakdown of the order of operations in Excel:

1. Parentheses (Brackets): Excel prioritizes calculations within parentheses first. Any calculations within parentheses are performed before anything else.

1. Exponents: Excel then evaluates exponentiation (raising a number to a power). For example, if you have calculations like 2^3, Excel will perform the exponentiation before moving to other operations.

1. Multiplication and Division (from left to right): Excel evaluates multiplication and division operations from left to right after parentheses and exponents. If you have a formula like 4 * 3 / 2, Excel will perform the multiplication first (4 * 3 = 12), then the division (12 / 2 = 6).

1. Addition and Subtraction (from left to right): Excel calculates addition and subtraction operations from left to right. For example, in the formula 5 + 3 - 2, Excel will add 5 and 3 first (5 + 3 = 8) and then subtract 2 (8 - 2 = 6).

It's important to note that while Excel follows this standard order of operations, you can use parentheses to override the default sequence.

FAQs

How do I force Excel to calculate?

In Microsoft Excel, you can manually force the recalculation of formulas and functions to update the values in your spreadsheet. There are a few different ways to do this:

Pressing F9

• You can force Excel to recalculate all formulas in the active workbook by pressing the "F9" key. It recalculates all worksheets in the workbook.

Using the Formulas Tab

• Go to the "Formulas" tab on the Excel ribbon.

• In the "Calculation" group, you'll see a button labelled "Calculate Now." Clicking this button will recalculate all formulas in the active workbook.

Using the Formulas Tab's Dropdown

1. Go to the "Formulas" tab on the Excel ribbon.

2. In the "Calculation" group, click the dropdown arrow next to "Calculate Now."

3. From the dropdown menu, you can choose:

4. "Calculate Sheet" to recalculate only the active worksheet.

5. "Calculate Workbook" to recalculate all worksheets in the active workbook.

6. "Calculate Active Cell" to recalculate only the formula in the currently selected cell.

Using the Shortcut

Pressing "Ctrl" + "=" (equal sign) is a shortcut to insert a formula into a cell manually, and it also recalculates the entire worksheet.

Changing Calculation Options

1. Go to the "File" tab (Excel 2010 and later) or the "Office Button" (Excel, 2007).

2. Click on "Options" (Excel 2010 and later) or "Excel Options" (Excel, 2007).

3. Go to the "Formulas" section in the Excel Options dialogue box.

4. You can choose different calculation settings under the "Calculation options" section. "Automatic" will recalculate the workbook whenever you make a change, while "Manual" requires you to recalculate using the methods mentioned above manually.

Please note that Excel usually recalculates automatically as you make changes to your worksheet, so manually forcing a recalculation is often necessary only in specific situations.

Why are my Excel cells not updating unless I double click?

If your Excel cells are not updating automatically when you make changes and only update when you double-click them, it is likely due to the calculation settings in Excel being set to "Manual" mode. In "Manual" calculation mode, Excel won't automatically recalculate formulas and functions when changes are made; instead, you need to trigger the recalculation manually.

To resolve this issue and make your Excel cells update automatically, follow these steps:

1. Change the Calculation Setting

2. Check for Circular References

Summary

Excel is a powerful tool for data analysis and automation, but formulas might sometimes not calculate as expected. This comprehensive article addresses various issues and provides step-by-step solutions to ensure your formulas work seamlessly.
