How Long Does It Take To Write a Book?

You have time to write a book. You just have to be honest about it.

I built the little calculator below so you can run your own numbers. Tell it how many words you can realistically write in a day and how many days a week you’ll genuinely show up, and it’ll tell you when your 80,000-word book will be finished. Be honest with it and it’ll be honest with you.

My first novel started with a drunken wager. A few Christmas drinks, a rash declaration that I’d write a book, and a bet I promptly forgot about until a friend cheerfully reminded me months later. So I sat down and typed the first page of a novel I had absolutely no idea how to write.

That’s the part people get wrong about authors. They assume we’re a different species — that we were born knowing where the commas go and how a plot holds together. We weren’t. I certainly wasn’t. The only thing that separated me from every other person who’s ever said “I’ve got a book in me” was that I kept turning up at the keyboard after the novelty wore off.

And here’s the bit nobody tells you: turning up doesn’t require you to quit your job, rent a cabin, or wait for the muse to descend. It requires two things: time, and honesty about how much of it you’ll actually give.

Let’s talk numbers, because this is where most would-be writers either give up or get delusional. A typical novel is around 80,000 words. That sounds enormous. It is enormous, if you insist on picturing all 80,000 arriving at once. Break it down, though, and it stops being a mountain and becomes a series of very manageable molehills.

Write 500 words a day, five days a week, and you’ll have a finished first draft in a little over eight months. That’s a page and a half. You’ve probably written longer emails to complain about a parking fine. Push it to 1,000 words a day and you’re looking at four months. Do a modest 250 words on just three days a week and it still gets done — it just takes longer, and that’s completely fine, as long as you’re honest that it’ll take longer and don’t sulk about it in month three.

The killer isn’t the word count. It’s the lie we tell ourselves about commitment. We plan our books at our most optimistic — a fresh notebook, a clear weekend, big ambitions — and then measure our progress against that fantasy version of ourselves who was going to write 2,000 words every single morning before work. When real life turns up, as it always does, we don’t adjust the plan. We just decide we’ve failed, and quietly shelve the whole thing.

So be realistic instead. Ambitious about the finished book, honest about the daily reality. Pick a number you can actually hit on a bad Tuesday, not a good one. Protect a slot in your week the way you’d protect a dentist appointment you can’t cancel. Then let the maths do the reassuring for you. If the arithmetic says your book will be done by next spring, that’s not a hope — it’s a schedule.

That’s the whole secret, and it’s a deeply unglamorous one. There’s no lightning bolt. No special permission required. Just a word count you can live with, a diary that reflects the truth about your life, and enough patience to let the pages stack up while you’re busy doing everything else.

You have time to write a book. Most people just never sit down and work out how much.

Frequently Asked Questions

How long does it take to write a book?

There’s no single answer — it depends on how many words you write and how often you sit down to do it. A typical 80,000-word novel takes a little over eight months if you write 500 words a day, five days a week. Write 1,000 words a day and you could have a first draft in around four months. The word count is fixed; the timeline is entirely down to your pace and consistency.

How many words is a typical novel?

Most novels land around 80,000 words. Genre plays a part — thrillers and romance often sit between 70,000 and 90,000 words, while fantasy and some literary fiction run longer — but 80,000 is a sensible average to plan your first book around.

Can anyone write a book?

Yes. Writing a book isn’t a talent you’re born with, it’s a habit you build. The people who finish aren’t necessarily the most gifted writers — they’re the ones who keep turning up at the keyboard and stay realistic about how much they can write each week.

How many words should I aim to write each day?
Pick a number you can hit on a bad day, not a good one. For most people writing around a day job, 250 to 500 words a day is realistic and sustainable. Consistency matters far more than the size of any single session — a modest daily habit beats an occasional heroic burst.

Do I need to write every day to finish a book?

No. Writing every day is one route, but three or four focused days a week will still get you there. What matters is protecting the time and being honest about your pace. A slower, steady schedule you actually stick to will always beat an ambitious one you abandon by March.

How does the book writing calculator work?

Enter how many words you can realistically write in a day and how many days a week you’ll write. The calculator assumes an 80,000-word book and tells you how many weeks it’ll take, the number of actual writing days involved, and roughly when you’ll finish if you start today.
