Counting words sounds like the simplest possible thing a piece of software can do, and yet paste the same paragraph into two different word counters and you'll sometimes get two different numbers. That's not a bug in either tool — it's because "word" is a slightly fuzzier concept than it looks, and different tools quietly make different decisions about how to handle the edge cases.
How a basic word counter works
At its core, most word counters do something close to this: split the text wherever there's a space, tab, or line break, and count how many pieces come out. This works well for ordinary prose, but it's a mechanical rule, not a linguistic one — it doesn't actually know what a "word" means, it just knows what whitespace looks like. That gap between the mechanical rule and the real concept is where the disagreements start.
Where the disagreements come from
Hyphenated compounds like well-known or mother-in-law get counted as one word by tools that split only on whitespace, but as two or three by tools that also split on hyphens. Numbers with commas or decimals (1,000 or 3.14) are usually one "word" to a whitespace-based counter, but some tools strip punctuation first and count differently. Em-dashes used without surrounding spaces —like this— can accidentally glue two words into one long token if a tool doesn't specifically handle that punctuation mark, quietly under-counting the real total.
URLs and email addresses are another common snag: a long web address with no spaces counts as a single "word" no matter how many real words' worth of information it contains, which can make a text with several links look shorter than it actually reads.
What most platforms actually count
Word processors like Microsoft Word and Google Docs generally count hyphenated words as one word and handle most punctuation sensibly, which is why their counts are often treated as the "reference" figure. Many simpler web-based counters use a plainer whitespace-split rule, which is faster to compute but slightly less refined at the edges. Neither approach is "wrong" — they're just different reasonable definitions of the same fuzzy concept, and the gap between them is usually small (a few words on a page-length piece of text) rather than dramatic.
Why the exact number rarely matters as much as it feels like it should
For almost every practical use — hitting a rough target for a school assignment, checking a blog post isn't too thin, gauging how long a message is — being off by a handful of words against a different tool's count doesn't change the underlying answer to "is this long enough." The cases where exact precision genuinely matters are usually ones with a strict, explicitly defined rule (a submission portal that states its own counting method, for instance), and in those cases it's worth counting with the same tool or method the rule-setter specifies, rather than trusting a general-purpose counter to match it exactly. When no specific method is stated, picking one reliable counter and using it consistently is a reasonable default.

Does a hyphenated word count as one word or two?
It depends on the tool. Word processors like Word and Google Docs typically count a hyphenated compound as one word, while some simpler whitespace-based counters may split it into two if the hyphen is treated as a separator.
Why does Microsoft Word's count differ from an online counter?
Word uses a more linguistically aware counting method that handles punctuation, hyphens, and numbers with some nuance, while many simple online tools just split text on whitespace, which is a slightly cruder rule that can land on a marginally different total for the same text.
Do numbers count as words?
Generally yes — a standalone number like 42 or 1,000 is typically counted as one word by most counters, since it's treated as a whitespace-separated chunk of text just like any other word.
