Pages Per Day Calculator to Finish a Book
The book
Use the last numbered page, not the page count an ebook app shows for your current font size.
Leave this at 0 if you have not started. Partway through, put in the real page number and the target recalculates from today.
Your deadline
Day 1 is your start date, so a 30-day run beginning on the 1st finishes on the 30th, not the 31st.
Challenge length must be between 7 and 365 days.
Your reading speed
238 wpm is the adult silent reading mean for non-fiction from Brysbaert (2019), which pooled 190 studies and more than 17,000 participants. Fiction came out at 260.
Book format
Reading an ebook with no fixed pages? Divide the total word count by 275 and use that as the page count, or take the page estimate your e-reader shows.
A number on a screen is not a habit. LockIn30 puts the daily target you just worked out on a day grid you tick off once an evening, and keeps a running streak and completion rate so you can see whether the plan is holding.

How the pages per day calculation works
Pages left divided by days left, rounded up. That is the whole calculation. A 320-page book over 30 days is 10.67 pages a day, which the calculator reports as 11.
The rounding up is not fussiness. Round 10.67 down to 10 and you arrive at Day 30 with 20 pages still to read, so the plan quietly fails on the last day. If you are already partway in, the sum uses pages left and days left rather than the original totals, so a slow first week shows up as a slightly higher number rather than a surprise at the end.
The second half is the part most calculators skip: turning pages into minutes. Multiply the daily page target by the words on a page, then divide by your words a minute. Both of those are inputs here, so the minutes figure changes when your book or your speed does. Competing tools hard-code something like 30 pages an hour, and that single constant is wrong for almost everyone: it is too slow for light fiction and too fast for a textbook. At the defaults of 275 words a page and 238 words a minute (the adult non-fiction mean from Brysbaert, 2019), you get roughly 52 pages an hour.
Pages a day by book length, with the minutes a day next to each, at those defaults:
| Book length | 7 days | 30 days | 60 days | 90 days |
|---|---|---|---|---|
| 200 pages | 29 pages, 34 min | 7 pages, 8 min | 4 pages, 5 min | 3 pages, 3 min |
| 300 pages | 43 pages, 50 min | 10 pages, 12 min | 5 pages, 6 min | 4 pages, 5 min |
| 400 pages | 58 pages, 67 min | 14 pages, 16 min | 7 pages, 8 min | 5 pages, 6 min |
| 600 pages | 86 pages, 99 min | 20 pages, 23 min | 10 pages, 12 min | 7 pages, 8 min |
The finish date follows the same convention the 30-Day Challenge End Date Calculator uses: the start date is Day 1, so a 30-day run is start date plus 29 days.
What a realistic daily page target looks like
Twenty to forty pages a day is the range most readers hold. At an average speed that is 25 to 50 minutes, which fits in an evening without displacing anything important. Under 20 pages the habit is easy to keep but the book takes a while. Over 40 it starts competing with sleep, and that is a competition reading loses.
So treat a target above 40 as information about the deadline, not about your willpower. If a 600-page book over 30 days is asking for 20 pages a day, fine. The same book over 7 days is asking for 86, which is over an hour and a half every night for a week. Stretching it to 60 days brings the target down to 10 pages a day, about 12 minutes. Nobody grades you on the deadline.
Genre moves the number as much as page count does. Light fiction runs 50 pages an hour or better, general non-fiction sits nearer 40, and textbooks or anything with equations and diagrams drop to 20 to 25 because you stop and re-read. Set the words per minute input to match what you are holding rather than to what you can manage on an easy novel, or the minutes figure will flatter you.
The trade-off: a smaller number you hit every day beats a larger number you hit twice a week. Ten pages a day finishes a 300-page book in a month. Fifty pages on Sundays finishes it in six weeks, if the Sundays happen.
Turning the number into a daily reading habit
The gap between knowing you need 11 pages a day and reading 11 pages a day is where most reading plans die. Nothing about the arithmetic helps with that part.
LockIn30 is built for the other part. Its task library already has Read (10 pages) in the Mind category, and the counter task type takes any target with plus and minus buttons, so the number this calculator produces goes straight in as your daily goal. You log it once a day, the day grid fills in, and the streak and completion rate tell you whether the plan is holding. The default run is 30 days, with anything from 7 to 365 supported, so it matches whatever length you picked above.
There is a choice to make about the rules before you start. Strict mode ends the run on a missed day, which suits a short sprint. Forgiving mode logs the miss and carries on, which suits a 90-day book you are reading around a job. Neither is the right answer for everyone, and the guide on strict vs forgiving habit tracking works through which one fits.
One detail worth knowing: the pace line here and the app's completion rate both use the same straight-line expectation, your progress against the share of the run that has elapsed. They will not disagree with each other, so you do not have to reconcile two different verdicts on the same book.
When you miss a night
Put your real current page in and press nothing else. The target recalculates from today, and the pace line tells you how far behind the straight line you are. On a 30-day book, one missed evening usually adds a single page a day, which you will not feel. That is the case for entering the honest number rather than the one you meant to reach.
A week behind is different. Now the daily target is meaningfully higher than the one you agreed to, and the choice is between a sprint, a longer deadline, or a restart. Extending is almost always the better option: the pages you have read still count, and the finish date moving by ten days costs you nothing. Restarting from Day 1 throws away real progress in exchange for a tidy number.
If you are weighing those options against each other, the Streak Restart Date Calculator puts the three side by side, with the finish date each one leads to.
Frequently Asked Questions
Common questions about pages per day calculator to finish a book
How many pages a day do I need to read to finish a book in 30 days?
Divide the pages left by 30 and round up. A 300-page book is 10 pages a day, a 400-page book is 14, a 600-page book is 20. At an average pace those are roughly 12, 16 and 23 minutes of reading. The calculator does the rounding for you and adds the minutes, which is the number that actually decides whether the plan survives contact with a Tuesday evening.
How many pages a day is realistic?
Twenty to forty pages a day is the range most people sustain, which is about 25 to 50 minutes at an average reading speed. Below 20 pages it barely registers as a commitment; above 40 it starts competing with everything else in the evening. If the calculator hands you a number well above 40, the honest fix is a longer deadline rather than a heroic daily target. For goals measured in something other than pages, the Daily Target Planner Calculator does the same split for any unit.
How long does it take to read 30 pages?
About 35 minutes for a typical paperback. That comes from 275 words a page and 238 words a minute, which works out at roughly 52 pages an hour. Dense non-fiction or anything with equations drops that to 20 to 25 pages an hour, so 30 pages could take well over an hour. Change the words per minute input to match what you are actually reading.
What is the average adult reading speed?
It is 238 words a minute for non-fiction and 260 for fiction. Those figures come from Brysbaert's 2019 meta-analysis in the Journal of Memory and Language, which pooled 190 studies and more than 17,000 participants. The claim that the average person reads at 300 wpm, repeated on most reading calculators, is above what that evidence supports. This calculator defaults to 238 for that reason.
How many words are on a page?
Around 275 for a standard 6x9 trade paperback, with the usual range running 250 to 300. Mass market paperbacks pack more in, roughly 300 to 350, because the type is smaller. Large print and illustrated books run nearer 200. Pick the chip that matches what is in your hands: it changes the minutes-a-day figure but not the pages-a-day target.
What if I fall behind?
Enter your real current page and the calculator recalculates from today rather than from the original plan. That is the whole point of the pace line: it tells you how many pages behind you are and what the new daily number is. One missed evening on a 30-day book usually adds a single page a day. Falling a week behind is when the target starts to look unpleasant, and at that point extending the deadline beats abandoning the book. The Challenge Completion Rate Calculator does the next part: your completion rate, and how many days you can still afford to miss.
Should I count every day or only the days I actually read?
This calculator counts every calendar day, because the thing you are building is a daily reading habit. If you only read on weekdays, the same deadline gives you about five sevenths of the days, so raise the target by roughly 40 percent, or shorten the book. Skipping weekends is fine for a work deadline and a poor fit for habit building, where the daily repetition is what makes it stick.
How many books a year does this pace add up to?
Finishing one book every 30 days is 12.2 books a year. Every 60 days is 6.1, every 90 days is 4.1, and a week per book is 52.1. Most people overestimate what they can do in a month and badly underestimate what 15 minutes a day turns into over a year.
