About Book Finish Date Calculator

Reading days per week is the term people forget. Twenty-two pages a day on five days a week is not the same as every day: the remaining pages divided by the daily rate gives reading days, which must then be stretched by 7/5 to get calendar days.

Formula

Finish date

reading days = pages remaining / pages per day; calendar days = reading days x 7 / reading days per week

Assumptions and limits

The result is derived only from the 4 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

Why track progress as a percentage?

Because it is motivating and it exposes the mid-book slump, where most abandoned books are abandoned.

Should I count pages or words?

Words are more comparable across books, since page density varies hugely. Pages are easier to track and fine within one book.
