Free IFS Formula Generator (2026) — Multi-Condition Logic
Checks multiple conditions and returns a value corresponding to the first TRUE condition. Cleaner than nested IFs.
IFS vs Nested IF
IFS evaluates conditions in order and returns the value for the first TRUE test—ideal for letter grades, tiered discounts, and commission bands without stacking IF(IF(IF(...))).
Minimum viable pattern
Always end with a catch-all: use TRUE as the last condition to assign a default (e.g. "F" or "Other").
Google Sheets & Excel
IFS works in Excel 2019+ / Microsoft 365 and Google Sheets. For older Excel, use nested IF or lookup tables.
Common Errors & Fixes
#N/A or wrong grade bucket
Causes:- Conditions out of order so a lower threshold matches first.
- Missing TRUE fallback.
- Comparing text scores without VALUE().
Fixes:- Put highest thresholds first.
- End with TRUE, "default".
- Use VALUE(A1) if scores are stored as text.
Frequently Asked Questions
Can IFS replace nested IF for letter grades?
Yes. Example: =IFS(A1>=90,"A",A1>=80,"B",A1>=70,"C",TRUE,"F"). Easier to read than multiple nested IFs.
Why does IFS return #N/A?
No condition matched and there is no final TRUE fallback. Add TRUE, "Default" as the last pair.
IFS vs SWITCH?
IFS tests ranges and inequalities; SWITCH matches exact values. Use IFS for grade bands and tier thresholds.
