1 Empty or Blank Column Values Causing NaN
What happens: Your formula returns NaN or a blank result on certain rows.
Why: When a referenced column is empty, monday.com passes a null value. Most math operations choke on nulls and return NaN.
The fix: Wrap your formula in an IF statement that checks for blank values.
IF({Numbers}="", 0, {Numbers} * 1.15)For date columns:
IF({Due Date}="", "", DAYS({Due Date}, TODAY()))2 Referencing an Unsupported Column Type
Supported types: Numbers, Text, Date, Status, People, Time Tracking. Auto Number, Tags, Files, Country, Rating, and Dropdown are NOT supported.
The fix: Create a Text or Numbers column and use an automation to copy unsupported column values into it.
3 Mismatched or Missing Parentheses
Build nested formulas from the inside out. Write the innermost calculation first, confirm it saves, then wrap the next layer around it.
ROUND({Revenue}/{Hours},2)
IF({Hours}=0,0,ROUND({Revenue}/{Hours},2))
IF({Revenue}="","No data",IF({Hours}=0,0,ROUND({Revenue}/{Hours},2)))4 Text vs. Number Formatting Conflicts
TEXT() and CONCATENATE() convert output to text. Use two columns: one numeric for calculations, one formatted for display.
5 Date Column Formula Errors
Use DAYS() for differences, WORKDAY() for business days, START_DATE()/END_DATE() for Timeline columns. Always write 0.25 not .25.

This is a platform limitation. Use a Status column updated by a separate automation, or use Make.com to read formula values via API.
7 Column Summary Shows N/A
Column summaries only work on numeric outputs. Remove TEXT()/CONCATENATE() or use Numbers column built-in formatting.
8 Hitting the 10,000 Character Limit
Break into multiple intermediate formula columns. Reference their results in a final column.
Quick Diagnostic Checklist
- Supported column types only?
- IF checks for blank values?
- Parentheses matched?
- Leading zeros on decimals (0.25 not .25)?
- Under 10K characters?
- Not triggering automations from formula output?
- No TEXT()/CONCATENATE() if you need summaries?
- Pro or Enterprise plan?
If your monday.com workspace depends on formula columns, getting these patterns right saves hours. If HR automations depend on formula outputs, revisit that design.
