How to Fix Excel IF and IFS Formulas Not Returning Zero

Question details

The user needs to correct a monthly cost formula using IF or IFS so that it correctly returns a zero when a referenced cell is blank or contains a zero, instead of continuing to calculate a cost.

How to Fix Excel IF and IFS Formulas Not Returning Zero

Product: Excel
Device & OS: not provided
Scenario: Calculating monthly costs based on funding dates, where specific reference cells might be blank or explicitly set to zero.
Observed behavior: The formula ignores the zero or blank values in the reference column and continues executing the cost calculation, resulting in an incorrect monthly amount instead of zero.

Before you start

Ensure that the cells you are referencing are formatted as 'General' or 'Number' and do not contain hidden spaces, as this can affect how Excel evaluates zero and blank values in logical formulas.

Solution 1Recommended

Reorder Conditions in the IFS Function

The IFS function evaluates conditions in the order they are written. Placing the zero check first ensures the formula stops and returns zero before calculating other conditions.

Because the IFS function returns the result for the very first TRUE condition it encounters, prioritizing your zero or blank cell criteria is crucial. If the calculation logic is placed before the zero check, Excel will execute the calculation first.

Select the target cell

Click on the cell containing the incorrect IFS formula that calculates your monthly cost.

Edit the formula

Click into the formula bar and adjust the order of your arguments so the zero test is first. For example, type: =IFS($J5=0, 0, M$2>=$J5, $E5/12).

Apply and fill

Press the Enter key to apply the corrected formula, then click and drag the fill handle at the bottom-right of the cell to update the remaining rows.

Condition Order: Always structure IFS formulas from the most restrictive or critical condition (like handling zero/blank values) to the least restrictive condition.

Solution 2

Use Nested IF and ISBLANK Functions

If you are using older versions of Excel or prefer standard IF statements, nesting IF with the ISBLANK function allows you to explicitly handle both empty cells and zeros.

Frequently Asked Questions

Why does Excel treat a blank cell as a zero in some formulas?

Excel's calculation engine often evaluates completely empty cells as zero during mathematical operations. However, logical functions like IF may not automatically equate them in all contexts. Using the ISBLANK function ensures blank cells are handled explicitly and accurately.

What is the difference between the IF and IFS functions?

The IF function evaluates a single logical condition and requires nested IF statements to test multiple conditions. The IFS function simplifies this by allowing you to test multiple conditions in a single continuous formula, returning a value for the first condition that evaluates to TRUE.

How do I hide zero values in my spreadsheet instead of deleting them?

You can hide zero values by going to File > Options > Advanced. Scroll down to the 'Display options for this worksheet' section, and uncheck the box labeled 'Show a zero in cells that have zero value'.
