What this planner works out
This planner takes the pages remaining, your reading speed and the time you read each day, and returns the hours left and the date you would finish.
The finish date is the useful output. Hours remaining is abstract; a date is something you can hold a book club or a library due date against.

Before you plan
- Reading speed in pages per hour varies enormously with the book. Thirty-five pages an hour is a reasonable general figure for fiction.
- Dense non-fiction, technical material and anything read for study go far slower — sometimes half the rate.
- Daily reading time should be honest. Ten minutes actually read beats an hour intended.
- Page counts differ between editions. A large-print or illustrated edition has more pages for the same text.
Reading speed is usually quoted in words per minute, which is hard to apply to a physical book. Pages per hour is directly measurable — read for twenty minutes, count the pages, multiply by three. It also automatically accounts for the edition's type size and layout, which a word rate does not.
How this calculator works
Pages remaining converted to hours, then to days:
Pages remaining = total − already read
Hours = pages remaining ÷ pages per hour
Days = (hours × 60) ÷ daily minutes, rounded up
Finish date = today + daysRounding days up means a part-day of reading counts as a day, which matches how reading actually happens. The date assumes reading every day; skipping days extends it proportionally.
Worked example: a 350 page book
Using the default figures — 350 pages with 40 read, at 35 pages an hour, reading 30 minutes a day:
- Pages remaining: 310
- Reading time left: 8.9 hours
- Days: 18
Eighteen days at half an hour a day. Doubling the daily time to an hour finishes it in nine — which is the more useful observation than the total, because the total does not change and the daily habit does. A book club meeting in a fortnight needs 35 minutes a day rather than 30, which is a small and achievable adjustment.
Common mistakes
- Using a generic reading speed. Measure your own, for the kind of book you are reading.
- Applying a fiction rate to technical material. It can be half as fast.
- Overstating daily reading time. Plan from what you actually do.
- Assuming every day. Skipped days extend the date proportionally.
- Comparing page counts across editions. They differ substantially.
Frequently asked questions
How do I measure my reading speed?
Read normally for twenty minutes and count the pages, then multiply by three for pages per hour. Repeat with a different book — the difference between a novel and a dense non-fiction title is usually large enough to be worth knowing separately.
Does speed reading work?
The evidence is not encouraging for the stronger claims. Research consistently finds a trade-off between speed and comprehension beyond a certain point, and that techniques promising several times normal speed do so largely by skimming. Reading regularly and with fewer interruptions improves effective speed more reliably than any technique.
How does an audiobook compare?
Audiobooks are typically narrated at 150 to 160 words a minute, which is slower than most people read, though playback speed can be increased. The useful difference is that listening can accompany other activities, which for many people adds hours of books a week that reading could not.
How many books can I read in a year?
At 30 minutes a day and 35 pages an hour, roughly 6,400 pages — around 20 average novels. Doubling to an hour a day gives 40. The daily habit matters far more than reading speed, which is why the finish date responds so strongly to the daily minutes and so weakly to everything else.
