Study Time Calculator
Plan study hours from a page count, reading speed and the review time retention actually needs.
The formula
Hours = pages ÷ pages per hour × (1 + review overhead)
Every result on this page comes from this formula. Nothing is rounded until the final display, so figures match a spreadsheet to the cent.
How to use the Study Time Calculator
- Fill in each field with your own figures — the defaults are only there as an example.
- The result updates as you type, so there is no button to press.
- Check the breakdown under the main result for the supporting numbers.
- Use the copy button to take the result with you, or share the link to reload the same inputs.
