It divides your word count by a speaking rate (words per minute). Most narration runs 130–160 wpm; this tool lets you pick slow, average or fast.
At an average pace (~150 wpm) about 150 words. A 30-second spot is ~75 words, and a 10-minute video is ~1,500 words.
A calm explainer reads slower than a punchy ad. Matching the pace to your content gives a far more accurate runtime estimate.
