About Us
Learn about the WCPM Calculator and how it helps educators assess reading fluency.
Our Story
WCPM Calculator was born from a simple frustration: educators were spending too much time on manual calculations and not enough time actually helping students improve their reading skills.
As teachers and reading specialists ourselves, we knew the formula by heart — (Total Words Read − Errors) ÷ Time in Minutes — but doing it repeatedly for every student, every assessment period, was tedious and error-prone. Spreadsheets helped, but they weren't designed for the fast-paced reality of classroom assessments.
So we built the tool we wished we had: a fast, free, beautifully designed WCPM calculator that works instantly in the browser — no sign-ups, no data collection, no complexity. Just enter your numbers and get results.
What started as a single calculator has grown into a complete Reading Assessment Toolkit — with tools for reading accuracy, prosody evaluation, text difficulty analysis, vocabulary extraction, progress tracking, and goal setting. Every tool is built with the same philosophy: professional-grade functionality, zero cost, total privacy.
