Proofreading Time
Estimate the time to proofread a document at a set pace.
About Proofreading Time
Proofreading runs faster than deep editing because it looks for surface errors rather than rewording, so proof speeds are typically higher. The page figure assumes roughly 400 words per single-spaced proof page. Knowing proofreading cost and time separately from editing prevents scope creep, since polishing for typos is much cheaper than restructuring prose.
Formula
Proofreading Time
Proofreading time = words / proofreading speed
- proofreading speed
- Words inspected per hour for typos and slips
Worked example
With the default values below, Proofreading Time returns Proofreading Minutes of 120. Change any input above and every figure here is recalculated in your browser.

Assumptions and limits
- The result is derived only from the 2 inputs listed above. Anything not among them is not part of the calculation.
- In particular, this calculator does not take inflation, tax, fees or charges or compounding frequency into account.
- Figures are rounded for display to 2 decimal places, so totals built from several rounded parts can differ slightly from the unrounded arithmetic.
How these calculators are built and tested is described on the Methodology page. If a figure looks wrong, please report it.
Frequently Asked Questions
How is Proofreading Time calculated?
Proofreading time = words / proofreading speed Proofreading runs faster than deep editing because it looks for surface errors rather than rewording, so proof speeds are typically higher. The page figure assumes roughly 400 words per single-spaced proof page.
Why does Proofreading Time matter?
Knowing proofreading cost and time separately from editing prevents scope creep, since polishing for typos is much cheaper than restructuring prose.
What values do I need to enter?
This calculator takes 2 inputs: Word count, Proofreading speed. The pre-filled defaults are a realistic starting point — replace them with figures from your own environment for a result you can act on.
