Reading Pages Per Day Calculator

How it is calculated

The tool subtracts the page you have reached from the book's total to get the pages still to read, remaining = total − current, then divides by the days available and always rounds the answer UP to the next whole page: pages per day = ceil(remaining ÷ days). Rounding up means that reading exactly that many pages every day finishes on time, with a small buffer on the last day. The tool treats "current page" as pages already finished, so if you are about to start page 87, enter 86. All three numbers must be whole; the total must be larger than the current page and the days at least 1, otherwise there is no result (so a finished book, current = total, shows nothing). The remaining pages and days are also displayed.

Common mistakes

• Entering the page you are starting rather than the page you have finished. Starting page 87 means 86 pages are read, so using 87 leaves one page less to read.
• Putting the pages left in the total box. The tool needs the book's total and your current page separately, so entering only the remainder produces the wrong answer.
• Ignoring the rounding up. Rounding 23.2 down to 23 pages makes you miss the finish date; the tool deliberately gives 24.
• Counting calendar days when you will skip some. If you only read on weekdays, enter the number of reading days, not the number of days until the deadline.
• Entering a fractional page or day count such as 14.5 days. Only whole numbers are accepted, so round the days down to be safe.
