How to Use COUNTIF Function in Excel

What this does

COUNTIF tallies cells that satisfy one condition. It scans range and counts every cell matching the criteria, which can be exact text, a number, a comparison like ">=50", or a wildcard pattern. It answers questions like how many orders are "Shipped", how many scores are at least 60, or — by counting a value against its own column — how many times an entry is duplicated. Keep the inputs visible and clearly labelled and the whole thing stays auditable — anyone who opens the file later, including you, can see at a glance exactly what feeds the result and change one assumption without hunting through the formula. The difference between a quick fix and a sheet you can trust is the extra minute you spend validating “use countif function in excel”. Start on a copy or a tiny sample, keep the affected formula visible, and compare the result with the tool above before you touch the real workbook. When a formula is involved, keep the inputs labelled beside it, reference cells instead of typing values, and apply number formatting only after the result checks out. The point is a calculation you can defend to a CFO or an auditor, but the practical win is that someone else can open the file and understand what happened without asking you.

A worked example

Order statuses are in C2:C200. To count how many are shipped: =COUNTIF(C2:C200, "Shipped"), returning say 143. To count scores of 60 or higher in B2:B200: =COUNTIF(B2:B200, ">=60"). To find duplicates of the value in A2, count it against the whole column: =COUNTIF(A:A, A2) — a result above 1 means the value repeats. COUNTIF is the quickest way to answer "how many" against one condition — open tasks, passing grades, repeated entries — without filtering or a pivot table. A practical tip before you scale it up: build it once on a small block of test data, confirm the number against the tool on this page, and only then point it at your real sheet. That one habit catches almost every mistake while it is still cheap to fix, long before a wrong figure reaches a report or a colleague.

In Google Sheets

If you are in Google Sheets rather than Excel, the good news is that the formula shown here is identical and the workflow barely changes — menus sit across the top instead of in a ribbon, and a few function names differ slightly, but anything you build here moves across with little or no rework. Nothing on this page is behind a login: the tool runs entirely in your browser, the formula is shown in full with one-click copy, and the steps work the same on Windows and Mac. That is the whole promise here — the exact answer, a way to prove it on your own numbers, and just enough context to make it stick. Here is the takeaway for “use countif function in excel”: copy the answer if you are busy, but if you have a spare few minutes, rebuild the example in Excel yourself with the tool above open beside it. That single pass — type it, run it, watch the result move when you change an input — is what turns a formula you found into a technique you trust. Keep your inputs labelled and referenced, never hard-coded, and the same sheet stays correct and auditable as it grows. Done that way, you will not need to look this up again, and you will be the person others ask.

Common mistakes

• Forgetting the quotes around a comparison — ">=60" must be a quoted string, not >=60 on its own.
• Expecting COUNTIF to handle two conditions; for multiple criteria use COUNTIFS instead.
• Counting blanks unexpectedly — "" and truly empty cells behave differently, so use "<>"&"" for non-blanks or COUNTBLANK for blanks.
