Math Updated 16 Jun 2026

Reading List Completion Time is a mathematics calculator that helps you calculate reading list completion time values from your input data. The formula used is: Days per Book = Pages per Book ÷ Pages per Day\nTotal Days = Days per Book × Books in List\nBooks per Year = 365 ÷ Days per Book. Ensure all inputs share the same unit system (e.g. all metres or all feet) unless the formula converts between units.

Formula

Days per Book = Pages per Book ÷ Pages per Day Total Days = Days per Book × Books in List Books per Year = 365 ÷ Days per Book

Example Calculation

Inputs
  • Books in Reading List: 20
  • Average Pages per Book: 300 pages
  • Pages Read per Day: 30 pages/day

Suppose you enter: Books in Reading List = 20, Average Pages per Book = 300, Pages Read per Day = 30. The calculator applies the formula (Days per Book = Pages per Book ÷ Pages per Day\nTotal Days = Days per Book × Books in List\nBooks per Year = 365 ÷ Days per Book) and shows all output values below. Change any input field to immediately see how the result changes.
