Excel PERCENTILE.INC Function

By · Last updated:

Chala mitrano — today PERCENTILE.INC. Cut at 50%, 90% — who cleared the band?

Fictional sample data for learning. Cut-scores for Vadodara exams and Auckland assessments. Mixed ₹ and $ bands.

Purpose

Return the k-th percentile of a range (inclusive 0..1).

Return value

The percentile value.

Syntax

PERCENTILE.INC(array, k)

Arguments

ArgumentRequired?Description
arrayRequiredRange of numbers.
kRequiredPercentile from 0 to 1 inclusive (0.5 = median).

Version

Excel 2010+ (older: PERCENTILE). LibreOffice / Sheets: PERCENTILE.

How to use — Why → What → How

Why: Exam boards set cut-scores with percentiles. PERCENTILE.INC(k) reads that point on your data. Cut-scores for Vadodara exams and Auckland assessments. Mixed ₹ and $ bands. In Indian back offices and foreign sister teams, PERCENTILE.INC shows up on scoreboards, QC sheets and queue dashboards every week.

What: PERCENTILE.INC includes 0 and 1 (min and max). k=0.5 matches MEDIAN for many sets. Bad k → #NUM!. Read every argument in the table once before you type; each one changes the answer on purpose.

How — numbered steps:

  1. Type =PERCENTILE.INC(B2:B100,0.9) for 90th.
  2. k between 0 and 1.
  3. Show MEDIAN as a sanity check at 0.5.

Ravindra Bagale's Tip

Friends, after PERCENTILE.INC, find one column or range in a real workbook this week where this lesson saves time.

Ravindra Bagale's Tip

Friends, sleep on PERCENTILE.INC; rebuild example 1 tomorrow without looking.

Ravindra Bagale's Tip

Friends, say the business question in plain words before =PERCENTILE.INC.

Ravindra Bagale's Tip

Friends, check a known case with a calculator before you trust a long PERCENTILE.INC chain.

Ravindra Bagale's Tip

Friends, after you finish PERCENTILE.INC, open yesterday’s real workbook and find one place this function would have saved ten minutes.

Ravindra Bagale's Tip

Friends, treat PERCENTILE.INC like a seatbelt on number columns — check a known case first.

About this data. Small demo rows for learning. Real sheets are longer; the same formula pattern scales when columns are clean.

Common errors and fixes

#NUM! — k outside 0..1. Fix: Fix k.
#VALUE! — Non-numeric k. Fix: Use a decimal.
INC vs EXC — EXC excludes 0 and 1 ends. Fix: Prefer INC unless a standard says EXC.

Notes and tips

  • Revisit the PERCENTILE.INC errors table after the quiz.
  • Build example 1 from memory on a blank sheet.
  • Check number vs text if a result looks wrong.
  • Teach one tip in Marathi or Hindi this week.
  • Keep currency symbols consistent inside one report column (practice mixes ₹ $ £ €).
  • Drill: set a 90th cut-score on a five-row mark list from memory.
  • PERCENTILE.INC vs QUARTILE.INC: any k versus fixed quarter cuts.
  • Fictional sample data only — names and amounts are for learning.
  • Print the PERCENTILE.INC revision card for one week of real worksheets.
  • Ask juniors to predict before they press Enter.
  • Track your top mistake with this function monthly.
  • Cut-scores for Vadodara exams and Auckland assessments. Mixed ₹ and $ bands.
  • Interview tip: explain the business question before the formula.
  • Classroom drill: invent three brand-new formulas from your city without the page open.
  • If a result looks wrong, check blanks vs zeros before rewriting.
  • When Excel versions differ, note the LibreOffice / Sheets fallback in a cell comment.
  • Prefer clear ranges over whole-column refs on huge sheets if speed matters.
  • Document units (₹, kg, days) in the header so totals stay honest.
  • Print the revision card for PERCENTILE.INC for one week of real worksheets.
  • When helping a junior, ask them to predict before Enter.
  • Share one tip with a classmate in Marathi or Hindi.
  • Keep currency symbols consistent inside a single report column.
  • Interview tip: explain the business question before the formula.
  • If a result looks wrong, check blanks vs zeros before rewriting maths.
  • When Excel versions differ, write a LibreOffice fallback under a comment.

In real work

Drill: set a 90th cut-score on a five-row mark list from memory. Cut-scores for Vadodara exams and Auckland assessments. Mixed ₹ and $ bands. Classroom drill: write three brand-new PERCENTILE.INC formulas on a blank sheet using names from your own city — if you can invent them without the page open, you own the skill. Then break one formula on purpose and watch the error; recovering from that break is half of interview readiness. Always verify with a known case before trusting a long chain. Keep a personal notebook of the one mistake you make most often with this function; review it monthly.
