Why isn't PERCENTILE.INC working in LibreOffice?
PERCENTILE.INC exists in LibreOffice 25.8.7.3, but it is not a drop-in match for
Excel — our executed tests found real behavioral differences (detailed in the test results on this
page). If a formula that works in Excel or Google Sheets misbehaves in LibreOffice, compare your usage
against the failing cases above before assuming your data is wrong.
Discovered quirks
- =PERCENTILE.INC(A1:A3,1.5) on LibreOffice Calc returned #VALUE!, but the documented/expected result is #NUM!. MISMATCH vs expected: expected '#NUM!', got '#VALUE!'

LibreOffice Calc 25.8.7.3 (tested 2026-08-06)
| Formula | Description | Result | Expected | Verdict |
|---|---|---|---|---|
| =PERCENTILE.INC(A1:A10,0) | k=0 is a valid boundary for PERCENTILE.INC and returns the minimum | 1 | 1 | Matched |
| =PERCENTILE.INC(A1:A10,1) | k=1 is a valid boundary for PERCENTILE.INC and returns the maximum | 10 | 10 | Matched |
| =PERCENTILE.INC(A1:A10,0.5) | k=0.5 (median); compare to PERCENTILE.EXC_k_half on identical data | 5.5 | 5.5 | Matched |
| =PERCENTILE.INC(A1:A3,1.5) | k outside [0,1] -> #NUM! | #VALUE! | #NUM! | Mismatch |
