Calculating your reading time (minutes) is straightforward once you know the Reading Time formula and what each input means. This guide explains the method in plain language, walks through a manual calculation, and gives worked examples you can follow — then you can do it instantly with the Reading Time Calculator.

What is Reading Time?

The Reading Time calculation tells you your reading time (minutes) from a few simple inputs. The figure you are solving for here is the reading time (minutes).

The Reading Time formula

The core formula is:

Reading time (minutes) = Word count ÷ Reading speed

Here is what each input means:

  • Word count — a number. Example: 1,500.
  • Reading speed — a value measured in words/min. Example: 200 words/min.

How to calculate it step by step

  • Write down the word count (for example, 1,500).
  • Write down the reading speed (for example, 200 words/min).
  • Apply the formula above to get your reading time (minutes).
  • Double-check the result with the Reading Time Calculator.

Worked examples

Example 1

Input / OutputValue
Word count1,500
Reading speed200 words/min
Reading time (minutes)7.5
Speaking time (130 wpm)11.5

With word count of 1,500 and reading speed of 200 words/min, the reading time (minutes) works out to 7.5.

Example 2

With word count of 3,000 and reading speed of 200 words/min, the reading time (minutes) works out to 15.0.

ResultValue
Reading time (minutes)15.0
Speaking time (130 wpm)23.1

Example 3

With word count of 750 and reading speed of 200 words/min, the reading time (minutes) works out to 3.8.

ResultValue
Reading time (minutes)3.8
Speaking time (130 wpm)5.8

Tips for an accurate result

  • Keep your units consistent — mixing, say, months with years or grams with kilograms is the most common source of error.
  • Round only at the very end. Rounding inputs early can shift the final answer noticeably.
  • Re-run the numbers whenever an input changes, rather than estimating from an old result.

Prefer not to do the maths by hand? — the Reading Time Calculator does it instantly, for free, with the formula and a worked example built in.
