Understanding GWAM (Gross Words a Minute)
GWAM — Gross Words a Minute — is the standard typing-speed metric taught in keyboarding classes and used in most typing certification and employment tests. Rather than counting actual dictionary words (which vary wildly in length), GWAM standardizes a "word" as 5 keystrokes, including letters, spaces, and punctuation. That makes speed comparable across any passage, regardless of vocabulary.
The formulas
Three numbers come from a timed typing test: the total characters typed (including spaces), the time taken in minutes, and the number of errors.
- Total words typed: Characters typed ÷ 5 (the standardized word length).
- Gross WAM (GWAM): Total words typed ÷ Time in minutes. This is raw speed with no penalty for mistakes.
- Net WAM: GWAM − (Errors ÷ Time in minutes). This penalizes speed for every uncorrected error and is the figure most tests actually score.
- Accuracy rate: (Total words − Errors) ÷ Total words × 100. Expressed as a percentage of words typed correctly.
For example, typing 250 characters in 5 minutes with 3 errors gives 50 total words, a GWAM of 10 words a minute, a Net WAM of 9.4, and an accuracy of 94%.
Common typing speed benchmarks
These bands are general guidelines used across many keyboarding programs, not a single certifying body's official cutoffs:
- Under 20 net WAM: beginner, still learning key placement.
- 20–40 net WAM: average for casual, everyday typists.
- 40–60 net WAM: above average; typical target for many office and administrative roles.
- 60–80 net WAM: professional level, often required for transcription or data-entry positions.
- 80+ net WAM: expert level, approaching court-reporting or specialist data-entry speeds.
How errors are counted
An "error" in most keyboarding programs is any deviation from the source copy — a wrong letter, an omission, an extra character, or a transposition — counted once per occurrence regardless of how many characters it affects. Consistent, honest error counting matters: undercounting errors inflates both Net WAM and accuracy.
