| 120,000 | 1,000 | 2 | 60 | 8.6 |
| 120,000 | 2,000 | 1 | 60 | 8.6 |
| 120,000 | 2,500 | 2 | 24 | 3.4 |
This table helps writers quickly identify approximate completion timelines considering their writing habits and goals. Adjustments to writing speed or session count significantly impact deadlines.
Formulas Behind the Book Completion Calculator
Understanding the underpinning formulas is crucial for customizing and interpreting your timeline estimates accurately.
The core formula for calculating the number of days to complete your manuscript is:
Days to Complete = Total Word Count / (Writing Speed per Session × Sessions per Day)
Where:
- Total Word Count (W): The full expected number of words of your book. Common book lengths range from 20,000 to 120,000 words, depending on genre and depth.
- Writing Speed per Session (S): Average words written per writing session. Writers often measure speed in the range of 500 to 2,500 words per session depending on typing proficiency and drafting style.
- Sessions per Day (N): The number of writing sessions undertaken daily.
To estimate the time in weeks, you can use:
Weeks to Complete = Days to Complete / 7
Additionally, when writing speed is calculated per hour instead of per session, incorporate writing hours per day (H):
Days to Complete = Total Word Count / (Words per Hour × Hours per Day)
Where:
- Words per Hour (Wph): Typing or drafting speed measured hourly.
- Hours per Day (H): Writing time dedicated daily.
To appreciate variation by session counts and speeds, you may also calculate completion time incorporating breaks or variability factors such as:
Adjusted Days = Days to Complete / Productivity Factor
Productivity Factor (P) accounts for days off, non-writing activities, or lower production days. Typically, values range from 0.5 to 1, where 1 means consistent daily productivity.
Common Variable Values and Interpretations
- Total Word Count (20,000–120,000 words): Depends on genre — short novellas (~20,000 words), typical novels (50,000–100,000 words), and epic tomes (100,000+ words).
- Writing Speed (500–2,500 words/session): Based on typing speed and drafting fluency. Professional writers can exceed 2,000 words per session during flow states.
- Sessions per Day (1–3): Session count varies by daily schedule and discipline; more sessions accelerate completion.
- Words per Hour (300–700+ words/hour): Typing plus thinking processes influence this; slower for research-heavy nonfiction.
- Productivity Factor (0.5–1): Accounts for non-writing days, distractions, or burnout, crucial for realistic schedules.
Real-World Applications of the Book Completion Calculator
Case Study 1: Fiction Writer Planning a 70,000-Word Novel
A professional fiction author plans to write a 70,000-word novel. The author wants precise scheduling and usually writes one session per day averaging 1,500 words.
Known variables:
- Total Word Count (W) = 70,000 words
- Words per Session (S) = 1,500 words
- Sessions per Day (N) = 1
Calculation:
Days to Complete = 70,000 / (1,500 × 1) = 46.67 ≈ 47 days
This means the novel can be completed in about 47 days of writing. Converting days to weeks:
Weeks to Complete = 47 / 7 ≈ 6.7 weeks
To account for rest days or unforeseen interruptions, the author applies a productivity factor of 0.8:
Adjusted Days = 47 / 0.8 = 58.75 ≈ 59 days
So, realistically, it will take approximately 8.4 weeks to finish the manuscript. This timeline helps the author plan deadlines, research periods, and editing phases with a clear understanding of writing pace.
Case Study 2: Nonfiction Author Using Hourly Writing Blocks
A nonfiction writer aims to complete a 100,000-word research book. The writer writes 2 hours daily, averaging 600 words per hour, balancing writing with extensive research.
Known variables:
- Total Word Count (W) = 100,000 words
- Words per Hour (Wph) = 600 words/hour
- Hours per Day (H) = 2 hours
Calculation of days:
Days to Complete = 100,000 / (600 × 2) = 83.33 ≈ 84 days
Converting to weeks:
Weeks to Complete = 84 / 7 = 12 weeks
The writer knows that productivity hits lower levels due to research demands and schedules a productivity factor of 0.75 to accommodate breaks and revisions:
Adjusted Days = 84 / 0.75 = 112 days
This adjustment extends the completion time to 16 weeks, which allows better-managed expectations and a balanced workflow between research, writing, and revisions.
Critical Tips for Maximizing Your Book Completion Calculator Accuracy
- Track Real Progress: To improve accuracy, log actual daily word counts and session times. Use data to refine estimates.
- Adjust for Life Variables: Include vacation days, holidays, and expected productivity dips directly in your productivity factor.
- Segment Writing Phases: Consider separate calculations for outlining, drafting, revising, and editing, as speeds differ.
- Use Writing Tools: Leverage software like Scrivener, Google Docs, or Microsoft Word integrated with track changes and word count for precision.
- Stay Flexible: Regularly revisit timeline assumptions and adapt your plan based on progress and changing writing conditions.
