WPM vs KPH: How to Read Your Typing Score
Worked examples of WPM, numeric KPH, corrections and accuracy using WPMTest’s actual scoring rules.
Practical guide · Updated October 28, 2026 · By the WPMTest team.
Match the measurement to the task
Prose typing measures how you reproduce sentences, spaces and punctuation. Numeric entry involves repeated digits, identifiers and decimal points. WPM is useful for prose; KPH expresses numeric entry as an hourly rate. Neither establishes that a complete customer or invoice record is correct.
Compare the same device, passage type, duration and correction rules. Touchscreen scores are not interchangeable with physical-keyboard scores. For employment, the actual employer’s instructions take priority over general practice advice.
Worked WPM calculation
WPMTest’s main WPM is correct characters remaining in the passage divided by five, then divided by elapsed minutes. Spaces and punctuation count. This convention does not count dictionary words.
For 250 correct characters in 60 seconds: (250 ÷ 5) ÷ 1 = 50 WPM. The same characters in two minutes give 25 WPM. If only 240 of 250 entered characters match, the main score after one minute is 48 WPM. Displayed values are rounded.
Corrections do not erase input history
Prose accuracy uses correct character inputs divided by all character inputs. Backspace is tracked separately. Correcting a wrong character repairs the final text but does not erase the original incorrect input from accuracy.
Suppose 250 final characters are correct after five wrong inputs were deleted and retyped. If these are the only extra inputs, 250 of 255 character inputs were correct: 98.0% accuracy. Raw WPM uses all character inputs, so extra corrections can raise it. Raw speed is not a quality score.
KPH extrapolates a shorter sample
Numeric KPM is entered characters divided by elapsed minutes. KPH = KPM × 60. For 300 entered characters in three minutes, KPM is 100 and KPH is 6,000. This does not prove you can maintain that pace for an hour.
WPMTest’s numeric tool counts separators between groups, including automatically inserted spaces. Backspace removes entries before scoring; numeric accuracy describes remaining text, not every corrected error. These rules differ from the prose trainer and may differ from employer software. Check formulas before comparing tools.
Choose the next exercise
For low prose accuracy, use the weak-key summary. For numeric errors, check decimal placement and leading zeroes before increasing pace. For large score swings, repeat comparable sessions instead of reporting only the fastest attempt.
Record date, device, duration, WPM or KPH, accuracy and your most common error. Keep mobile and hardware-keyboard results separate. Your progress is saved locally; clearing browser data removes it unless you export a backup.
How to use this guide
The worked examples use fictional records and WPMTest’s scoring rules. Compare the same duration, passage format and input method when tracking progress. For an employment assessment, use the provider and requirements in the job instructions.
