How to Calculate Your Own Typing Accuracy Percentage

Key Points

Accuracy = correct characters divided by total characters attempted, expressed as a percentage.
Different platforms count "errors" differently — some count by character, some by word.
A 95% accuracy score on a 1-minute test at 60 WPM means roughly 15 character errors.
You should target 97% or higher before worrying about speed improvements.
Understanding the formula lets you spot when a site's score doesn't match what employers will see.

The Basic Accuracy Formula

Typing accuracy is calculated by comparing what you typed against what you were supposed to type. The standard formula is:

Accuracy (%) = (Correct Characters / Total Characters Typed) × 100

Where "total characters typed" includes correct characters, incorrect characters, and any extra characters you typed beyond what was in the passage.

Example: you type 300 characters in a test. 285 are correct, 15 are errors. Your accuracy = (285 / 300) × 100 = 95%.

Character-Level vs Word-Level Accuracy

Some platforms calculate accuracy at the character level (counting each incorrect character as one error). Others calculate it at the word level (a word with any error counts as completely wrong). Word-level accuracy produces a lower accuracy percentage for the same number of mistakes, because a single typo in a long word invalidates the whole word.

Error counting method	Example scenario	Resulting accuracy
Character-level	3 wrong characters out of 300 typed	99%
Word-level (3 words affected)	3 words with errors out of 60 words typed	95%
Uncorrected error penalty only	10 characters left uncorrected out of 300	96.7%

This is one reason scores differ between platforms. A character-level accuracy of 98% might translate to a word-level accuracy of 92% if your errors cluster in specific words. Always check which method a platform uses before comparing scores. For the full picture on how platforms differ, see why accurate tests matter more than raw speed.

What Accuracy Percentages Mean in Practice

Accuracy %	Errors per 100 characters	Real-world interpretation
99%+	1 or fewer per 100	Professional / transcription quality
97–98%	2–3 per 100	Strong — meets most employer requirements
95–96%	4–5 per 100	Acceptable for general office; below legal/medical
90–94%	6–10 per 100	Errors are noticeably affecting net WPM
Below 90%	10+ per 100	Speed is not the main problem — accuracy is

How to Track Your Own Accuracy

The easiest way to track your accuracy is to use the accuracy test as a regular diagnostic tool. Take it alongside your regular speed test each session and record both numbers. Watch for patterns: does your accuracy drop when you push for speed? Does it stay the same? Does it improve with specific practice?

If your accuracy is consistently below 97%, that's your primary improvement target. Speed improvements built on a high-error foundation are unstable — they collapse under pressure or when you encounter unfamiliar text.

What Employers Measure

Most formal typing assessments report both WPM and accuracy percentage in the results. Job postings that list typing requirements often specify both: "minimum 60 WPM at 97% accuracy." If only WPM is listed, assume 97% accuracy is the implicit requirement — most employers reject applications where accuracy is below 95% even if the WPM is technically above the minimum.
