How to Write a COUNTIF Formula 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. Treat “write a countif formula in excel” as a small repeatable workflow rather than a one-off click you hope to remember next time. Use a small test block before the live file, so any surprise in the affected formula shows up while it is still harmless. 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. That turns a calculation you can defend to a CFO or an auditor into a method you can reuse, explain, and defend when the workbook leaves your screen.

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. If there is any chance you will reuse this, drop it into a small template tab right now: a labelled input area on the left and the formula beside it, checked once against the tool above. Next time the same question comes up, the answer is a single paste away instead of a rebuild from memory.

In Google Sheets

Google Sheets handles this almost identically to Excel. The formula syntax above is the same, and the menu lives under a slightly different label rather than a ribbon tab. Use the platform toggle at the top of the page to switch every keyboard shortcut between Windows and Mac, and expect at most cosmetic differences in naming. 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. If you take one thing from this page on “write a countif formula in excel”, make it the habit rather than the keystrokes: set the problem up with labelled inputs, reference those cells, and let Excel do the recomputing. Bookmark the page for the syntax, but do the example once in a blank sheet and check it against the tool above — five minutes of hands-on practice fixes the method in memory far better than re-reading, and it surfaces the small snags while they are still harmless. After that the technique is genuinely yours: faster than searching for it again, and reliable enough to drop into work that other people depend on.

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.
