Book Writing Timeline Calculator
Calculate how long it will take to write a book from daily word count goal and target length.
Includes realistic buffer for revision and rest days.
Most writing advice overestimates how fast a first draft can realistically be completed. This calculator gives you a grounded timeline that includes revision time and rest days.
First draft time
days_draft = target_words / daily_words
This is the raw math. Stephen King writes 2,000 words per day consistently. Most working novelists manage 500-1,500 words. Academic nonfiction writers working around day jobs often average 300-500. Be honest about your average — a fast bad day might produce 200 words, and your typical average over a week is usually lower than your best day.
The revision multiplier
First drafts are just the beginning. A novel typically goes through:
- First-pass revision (structure, pacing, character arcs): adds 40-60% more calendar time
- Line editing (sentence-level work): 20-30% more
- Copyediting (grammar, consistency): 10-15% more
Combined, revision typically doubles or triples the total time of the first draft. Academic or nonfiction books that require research interspersed with writing can take even longer.
Rest days
Writing every single day is sustainable for some writers but leads to burnout for most. The calculator lets you set 1-2 days off per week and adds realistic buffer to the total timeline.
Words per book type:
- Short story: 1,000-10,000 words
- Novella: 20,000-40,000 words
- Novel (commercial fiction): 70,000-100,000 words
- Literary novel: 80,000-130,000 words
- Nonfiction (narrative): 60,000-90,000 words
- Academic book: 80,000-120,000 words
