Plan to read all 1,189 chapters.
66 books · 1,189 chapters. Pace assumes daily reading with no catch-up days.
CPD = ⌈(T − C) / D⌉
The calculator uses a straightforward division formula. The total number of chapters in the Bible (1,189) is divided by the total number of days in your reading plan. The result is rounded up to the nearest whole chapter so you never fall behind your target.
If you have already completed some chapters, enter your progress and those chapters are subtracted first, giving you an adjusted remaining target.
CPD = ⌈(1,189 − 0) / 365⌉ = ⌈3.2575…⌉ = 4
Result: You need to read **4 chapters per day** to finish all 1,189 chapters in 365 days. At exactly 3.26 chapters per day the raw average is just over 3, but rounding up to 4 keeps you comfortably ahead of schedule. Reading 4 chapters daily for 365 days covers 1,460 chapter-slots, giving you 271 buffer slots for rest days or re-reads.
Your result tells you the minimum whole-chapter daily reading target needed to complete the entire Bible within your chosen period. Because the calculator uses a ceiling function, you will always finish on time or slightly early. A 365-day plan requires 4 chapters daily; a 180-day plan requires 7 chapters daily; a 90-day plan requires 14 chapters daily. The weekly summary multiplies your daily target by 7 so you can plan your reading sessions in advance.
The Protestant Bible contains 66 books — 39 in the Old Testament and 27 in the New Testament — divided into exactly 1,189 chapters. (The Catholic Bible adds deuterocanonical books and has more chapters; this calculator uses the 1,189-chapter Protestant canon by default.)
The chapter divisions we use today were introduced by Stephen Langton, Archbishop of Canterbury, around 1227 AD. Verse divisions were added by Robert Estienne (Stephanus) in 1551. These are editorial aids — they do not appear in the original Hebrew, Aramaic, or Greek manuscripts.
| Plan Length | Days | Chapters/Day (rounded up) | |---|---|---| | 3 months | 90 | 14 | | 6 months | 180 | 7 | | 1 year | 365 | 4 | | 2 years | 730 | 2 |
The average adult reads at roughly 200–250 words per minute. The King James Version contains approximately 783,137 words, meaning a cover-to-cover reading takes roughly 52–65 hours of actual reading time. At 4 chapters per day in a one-year plan, each daily session takes about 10–15 minutes — very achievable.
This calculator works for any reading order — canonical (Genesis to Revelation), chronological, or New Testament first. Total chapters remain 1,189 regardless of order, so your daily target is unchanged.
Research on habit formation suggests attaching a new habit (daily Bible reading) to an existing routine (morning coffee, lunch break, bedtime) significantly improves consistency. Missing a day? Simply recalculate by entering your updated chapters-completed figure and remaining days to get a fresh daily target.
Reading the entire Bible aloud at a normal speaking pace of roughly 150–180 words per minute takes approximately 70–80 hours. Many audio Bible recordings confirm this range, with complete KJV audio versions running between 70 and 84 hours.
Many Bible scholars recommend beginners start with the Gospel of John, then Psalms and Proverbs, then the rest of the New Testament, and finally the Old Testament. Chronological plans that follow historical sequence are also popular because they provide narrative context. The total of 1,189 chapters is the same regardless of order.
The King James Version contains approximately 783,137 words. The New International Version (NIV) is shorter at around 727,969 words. Word counts vary by translation, but the chapter count of 1,189 (Protestant) is consistent across English translations.
Yes — the M'Cheyne Reading Plan (1842) is one of the most famous, assigning 4 passages daily that blend Old Testament, New Testament, Psalms, and the Gospels. Our calculator can approximate any such plan; simply ensure your daily chapter target matches your chosen plan's total.
Surveys by the American Bible Society (State of the Bible reports) consistently find that fewer than 20% of self-identified Christians report reading the Bible through completely. A personalised reading plan with a concrete daily chapter target is one of the most effective tools for improving completion rates.
The Protestant Bible contains exactly 1,189 chapters across 66 books — 929 chapters in the 39 Old Testament books and 260 chapters in the 27 New Testament books.
You need to read 4 chapters per day (ceiling of 1,189 ÷ 365 = 3.26). At 4 chapters daily for 365 days you cover 1,460 chapter-slots, finishing the 1,189 chapters well before the year is up and giving you buffer days.
Yes. Enter the number of chapters you have already completed in the 'Chapters Completed' field. The calculator subtracts that from 1,189 and divides the remainder by your remaining days to give you a fresh, accurate daily target.
A 90-day plan requires ⌈1,189 ÷ 90⌉ = ⌈13.21⌉ = 14 chapters per day, which takes roughly 35–45 minutes of reading daily at an average adult reading pace.
The default total is 1,189 chapters (Protestant canon). For the Catholic Bible, which includes the Deuterocanonical books, the total is approximately 1,334 chapters. You can manually override the total chapters field if your calculator version supports it, or contact us for a Catholic edition.
Obadiah (Old Testament) has just 1 chapter, while 3 John (New Testament) also has 1 chapter. The longest book is Psalms with 150 chapters. These individual lengths don't affect the plan calculation — only the cumulative total of 1,189 chapters matters.
