How Different Tests Handle It
Worth knowing: Most typing tests penalize uncorrected errors more heavily than corrected ones — a single uncorrected mistake often costs more to your accuracy score than 2-3 backspace corrections along the way.
Typing tests take one of two general approaches. Some score only the final text you submit — if you catch and fix a mistake before finishing, it's as if it never happened. Others track your full keystroke history, including every backspace, and factor that activity into your accuracy score even if the final text is perfect.
Gross WPM vs. Net WPM, With Backspace
Gross WPM counts every character you typed, including ones you later deleted, which means heavy backspacing can lower your effective typing rate even if your final text is completely correct — the deleted characters still took time to type and undo. Net WPM subtracts errors from your final result, so a mistake you catch and fix generally counts less against you than one left in the text.

Take the Typing Speed Test →Is Correcting Mistakes Worth the Time Cost?
Usually, yes. An uncorrected error typically costs more in net WPM than the brief pause needed to backspace and fix it, since most scoring methods weight final accuracy heavily. The exception is excessive, habitual backspacing on minor typos that don't meaningfully affect readability — that pattern can cost more time than it saves.
What This Means for Your Typing Habits
- Fix clear mistakes — the accuracy benefit usually outweighs the time cost
- Don't obsess over minor typos if your test scores gross accuracy leniently
- Check which scoring method a specific test uses before assuming your habits are being measured a certain way
- Focus practice on reducing how often mistakes happen in the first place, not just how you handle them after

Because tests differ in how they calculate speed and handle corrections, the same typing performance can produce different WPM figures on different tests. Understanding what WPM actually measures helps explain why your score might vary from one typing test to another even when your actual typing hasn't changed.
A Practical Way to Think About It
Rather than trying to optimize around exactly how one specific test scores backspace, it's more useful to focus on accurate, rhythmic typing in general. A typist who makes fewer mistakes in the first place needs less correction either way, which improves the score on any test regardless of its specific backspace handling.
Building the Habit That Actually Helps
Slowing down slightly during practice, prioritizing correct finger placement over raw speed, tends to reduce how often backspace is needed at all — which helps every scoring method at once, rather than trying to game one specific test's rules around corrections.

Frequently Asked Questions
Does backspace count against your typing score?
It depends on the test. Most typing tests don't penalize the backspace keystroke itself, but the time spent backspacing still counts against your overall time, and the original mistake may still count as an error even after it's corrected.
Is it better to backspace and fix a mistake, or keep typing?
For net WPM, fixing a mistake usually improves your score more than leaving it, since net WPM subtracts uncorrected errors. For gross WPM, which counts raw characters typed, backspacing costs time without adding to your character count.
Do all typing tests measure backspace the same way?
No. Some tests only score the final submitted text, effectively erasing the mistake if corrected. Others track every keystroke, including backspaces, and factor that history into the accuracy score.
Should I avoid using backspace to type faster?
Not as a rule. Accuracy generally matters more than avoiding corrections, since an uncorrected mistake usually costs more in net WPM than the brief time spent fixing it.
