How long does it take to write a novel (the math)

How long does it take to write a novel? For most people, somewhere between six months and two years, depending on how much time you protect each week and how many drafts you do. The honest answer beyond that is: it depends on you. Not on averages, not on famous authors, not on some rule you read in a writing book. It depends on your word count target, the time you can protect each week, and whether you treat writing like a job or a mood.

That said, there are real numbers here. Let’s work through them so you can calculate your own timeline instead of waiting to discover it the hard way.

How long does it take to write a novel? Most authors take 6 to 12 months to finish a first draft, based on a 2021 Reedsy survey. At 500 words a day, an 80,000-word draft takes about 5 months. At 200 words a day, it takes about 13 months. The full novel, including revision, typically runs 1 to 2 years.

• At 200 words/day: 80,000 words in about 13 months
• At 500 words/day: 80,000 words in about 5 months
• At 1,000 words/day: 80,000 words in about 2.5 months
• Add at least as much time again for revision before the manuscript is ready

The spectrum is enormous (and that’s okay)

Ray Bradbury wrote the first draft of Fahrenheit 451 in nine days, spending $9.80 on a coin-operated typewriter in the basement of UCLA’s Powell Library. “It was a dime novel,” he said. It became one of the most read books of the 20th century.

J.R.R. Tolkien spent sixteen years writing The Lord of the Rings. Donna Tartt took eight years for The Secret History, starting it as a student at Bennington. She has said she can’t write quickly and doesn’t think it would serve her readers if she tried. J.K. Rowling took five years on Harry Potter and the Philosopher’s Stone, writing in Edinburgh cafes while her infant daughter slept, during one of the hardest stretches of her life.

John Boyne wrote The Boy in the Striped Pajamas in two and a half days. The story came to him so fully formed, he said, that he wrote it in a single sustained burst.

Nine days to sixteen years. The spectrum is that wide. What this tells you: the timeline is not a signal of quality or commitment. It’s a signal of scope, method, and circumstance.

First, decide how long your novel needs to be

Before you calculate anything, you need a target word count. Genre matters here.

Kindlepreneur’s analysis of Amazon’s Top 100 bestsellers shows fantasy and historical fiction averaging around 109,000 words, literary fiction around 98,000, and mystery, thriller, and romance ranging from 89,000 to 91,000. If you’re a debut author, most publishing professionals recommend aiming for 70,000 to 90,000 words. It’s easier for publishers to take a chance on a tighter manuscript.

For the math that follows, I’ll use 80,000 words as a working target. Adjust for your genre.

Here is how the numbers break down by genre at a 500-word-per-day pace:

The math: daily output times target equals your finish date

This is the part writers avoid because it makes the timeline feel real. But it’s also the only part you can control.

Stephen King writes 1,000 words a day. Graham Greene wrote 500. Brandon Sanderson writes around 2,500. Salman Rushdie writes 400 to 500. None of these are the right number. The right number is the one you can hit on a tired Tuesday.

For an 80,000-word draft:

• 200 words a day gets you there in about 13 months
• 500 words a day gets you there in about 5 months
• 1,000 words a day gets you there in about 2.5 months

The NaNoWriMo math is the cleanest proof of concept: 1,667 words a day for 30 days equals 50,000 words. Since 2006, nearly 400 NaNoWriMo novels have been traditionally published. Wool, Water for Elephants, and The Night Circus all started as NaNoWriMo manuscripts. The sprint works, when you protect the time.

But here’s the thing: it’s not about writing fast. It’s about not stopping. A slow daily habit beats fast sporadic bursts every time. 300 words a day is 109,500 words in a year.

How long does a first draft take

A 2021 Reedsy survey found that most authors take six months to a year to complete a draft. That’s experienced authors. First-timers often take longer, mostly because of one habit: editing while drafting.

King’s rule in On Writing is worth taking seriously. He believes the first draft of a novel should take no more than three months. His reason is practical, not competitive: “Any longer and the story begins to take on an odd foreign feel, like a dispatch from a foreign department.” The story stays alive in your head when you keep moving. Let it sit too long and you start to forget why it mattered.

Three months is aggressive for most people. Six to twelve months is realistic for someone writing around a full life. Both are fine. What matters is that you keep the draft moving forward, not backward.

If you think in hours rather than months: a 70,000-word novel at 1,000 words per hour takes roughly 70 hours of drafting. Add revision (typically 50 to 100% of draft time) and you are looking at 100 to 140 hours total for the draft phase alone. Author Jennifer Ellis documented 376 hours writing a nonfiction book. A memoirist tracked 736 hours from inception to final manuscript on a 77,000-word novel. Those numbers are not intimidating once you spread them over a year. Two hours a week is still 104 hours in twelve months.

What actually slows writers down

This is the honest list, not the flattering one.

Editing while drafting is the most common timeline killer. You rewrite chapter one six times and never reach chapter five. The first draft’s job is to exist, not to be good.

Writing with no outline is the next trap. Discovery writers (pantsers) often produce more spontaneous prose, but they also face more structural rewrites. Adding months of revision because the plot collapsed in act two is a real cost. A light outline, even just scene-level notes, is insurance.

Research rabbit holes catch historical and science fiction writers most. The research never feels complete, so set a boundary before you start.

Waiting for the right conditions stops more books than the rest combined. E.B. White said it plainly: “A writer who waits for ideal conditions under which to work will die without putting a word on paper.” Rowling wrote around a sleeping infant. Bradbury wrote in a library basement because he couldn’t afford an office.

And with no external structure, no deadline and no accountability, the weeks disappear. This is where a consistent method matters more than talent.

If you’re still working out how to approach the work itself, the post on how to write a novel covers the structure and process end-to-end.

Plotting vs. pantsing: how your method changes the math

Outliners spend more time upfront but tend to write faster drafts and need less structural revision. Discovery writers write more intuitively but often face complete redrafts when the story goes sideways.

King, Lee Child, and Nora Roberts are all notable pantsers. Many successful authors use a hybrid: a loose scene-by-scene outline that keeps them oriented without constraining how the story develops.

If timeline matters to you, an outline is the single most practical investment. Not because spontaneity is bad, but because fixing structure in revision costs months you don’t need to spend.

How long does the full novel take, start to finish

The draft is only the beginning. Plan for at least as much time again for revision.

A serious editing pass involves structural work (does the story hold together?), character and scene work (does it feel true?), prose-level editing, and at minimum one round of feedback from readers who aren’t your friends. That’s before copy-editing.

If you’re pursuing traditional publishing, the timeline from finished manuscript to bookstore shelf runs 18 months to 3 years. Querying agents alone takes 3 to 12 months. Publisher submission another 3 to 9 months. Design and production 9 to 18 months. That’s after you finish writing.

Self-publishing is faster. Experienced writers can go from finished draft to published book in around 65 days, covering editing, formatting, and cover design. But you still need a clean, revised manuscript before any of that starts.

How to set your own deadline

Here’s the process, step by step.

1. Pick your target word count based on genre (use the Kindlepreneur data as your starting point).
2. Audit your actual available writing time. Not your ideal schedule. The slots you can protect five days a week, even on bad weeks.
3. Set a conservative daily target. If you’re new, start at 300 to 500 words. You can always write more.
4. Divide your target word count by your daily target. That’s your draft deadline.
5. Add revision time. At minimum, equal to the draft time. For a first novel, plan on more.

The Blue Pencil Agency recommends giving yourself two years total for a first novel. Author Merilyn Simonds put it well: “I no longer think that a book should be written in a prescribed amount of time. Thinking deepens in that time away.” Two years sounds long until you’re six months into drafting and realise revision is a whole other book.

If you want a free way to track your sessions while you plan and draft, there are good free novel writing software options worth knowing about before you commit to a paid tool.

If you’re not sure how to structure the actual work before you start the clock, how to start writing a book is a good place to begin.

The only variable you actually control

Word counts of famous authors are useful data, not targets. King’s 1,000 words a day works for King, who has been doing it for decades. What the neuroscience supports is simpler: regular writing reinforces the habit, making the work progressively easier. Sporadic ambitious sessions tend to collapse. Small consistent sessions compound.

Haruki Murakami said: “People need routines. It’s like a theme in music.” The writing habit is the same. You don’t need to be fast. You need to be there. That consistency is part of why I built Penflow: not to make writing faster, but to make it easier to see whether you are actually showing up.

The National Centre for Writing has documented that starting small, 15 minutes or 200 words, is more sustainable than setting ambitious targets that fall apart by week two. 200 words a day is 73,000 words in a year. That’s a novel.

Frequently asked questions

How long does it take to write a chapter?

It depends on length and complexity, but most writers produce a chapter every one to three weeks at a normal pace. A 2,500-word chapter at 500 words a day takes five days of writing. Heavier revision or complex scenes push that to two weeks. A chapter a month is still a novel in two years.

How long does editing take after the first draft?

Budget at least as long as the draft itself. A structural edit, line edit, and final proofread on an 80,000-word manuscript typically runs three to six months for a careful solo writer. With a professional editor, the process is faster but there is still significant back-and-forth. First-time novelists often underestimate this by half.

Can you write a novel in a month?

Yes, and it has been done many thousands of times. NaNoWriMo proves it annually: 1,667 words a day for 30 days equals 50,000 words. That is a short novel, or a solid first act of a longer one. What you get at the end is a rough draft, not a finished book. But a rough draft in hand is worth more than a perfect plan in your head.

There is no average that applies to your novel. But the math is real, and it’s on your side if you use it. Pick a word count. Pick a daily minimum. Open a calendar. Mark the date. That’s your deadline.

Penflow tracks your writing sessions and shows your timeline updating in real time as you write, which makes the math feel less abstract. Free for one novel, with an AI layer available if you want it.

The writers who finish aren’t necessarily the fastest. They’re the ones who kept going on the days it felt pointless. That’s the whole secret.
