About Reading Comprehension Score Calculator

Comprehension score is simply correct answers over total, but pairing it with rate matters because speed and accuracy trade off. 34 of 40 in 25 minutes is 85% at 1.36 correct answers a minute. Reading research treats 90% or above as independent level and below 75% as needing instructional support.

Assumptions and limits

  • The result is derived only from the 3 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 3 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

Why measure rate as well as accuracy?

Because a reader who is accurate only when given unlimited time will struggle with real reading demands. Both matter for fluency.

What accuracy indicates independent reading level?

Conventionally 90% or above for comprehension and 95% for word recognition. Below 75% the text is at frustration level.
