Developmental Editor Cost: 2026 Rates by Word Count

A developmental edit of a novel typically costs 3.0 to 3.5 cents a word, according to the Editorial Freelancers Association (EFA) 2026 rate chart. For an 80,000-word novel, that comes to $2,400 to $2,800.

Non-fiction costs more, at 4.0 to 5.0 cents a word, so 80,000 words of non-fiction comes to $3,200 to $4,000. To work it out for your word count, try the free book editing cost calculator, which uses the same EFA rates.

This guide sticks to developmental editing: what the rates mean, how a developmental edit compares with a manuscript assessment and a line edit, what pushes a quote up, and how to prepare so your money buys an editor's judgment.

Key takeaways

• The EFA's 2026 rate chart lists developmental editing at 3.0 to 3.5 cents a word for fiction and 4.0 to 5.0 cents for non-fiction.
• At those rates, a 100,000-word novel comes to $3,000 to $3,500, and 100,000 words of non-fiction to $4,000 to $5,000.
• A manuscript assessment is listed at 1.5 to 1.8 cents a word, about half the price of a fiction developmental edit.
• A 90,000-word novel is roughly 36 to 65 hours of editing at the pace EFA members report.
• The EFA does not set rates. It calls its figures median rate ranges and says individual members' rates may vary considerably.
• A revised, consistent draft lets the editor spend those hours on structure instead of on contradictions you could have caught yourself.

Typical developmental editing rates in 2026

A useful public benchmark is the rate chart from the Editorial Freelancers Association. The 2026 edition is built from a survey of members' 2025 rates, and it is published on the EFA rates page.

For developmental editing, it lists:

Per-word rates and pages per hour from the EFA 2026 rate chart, as shown on its rates page (archived 8 October 2026). Per-page figures are our arithmetic at 250 words a page.

Before you compare quotes against these numbers, keep three things in mind.

• The EFA does not set rates. It reports what its members said they charge. It is a benchmark, not a price list.
• These are median rate ranges. The EFA says individual members' rates may vary considerably, so expect some quotes above or below them.
• A "page" is a unit, not your printed page. The chart counts 250 words as a page, so 90,000 words is 360 pages whatever your file shows.

What the hours tell you

The pages-per-hour column shows what you are paying for: time spent reading closely.

A 90,000-word novel is 360 pages. At 5.5 to 10 pages an hour, that is about 36 to 65 hours of editing.

Non-fiction moves more slowly on the chart. An 80,000-word non-fiction book is 320 pages, and at 4 to 8 pages an hour that is 40 to 80 hours.

Some editors quote by the hour, some by the word and some a flat project fee. The per-word figure is the easiest to compare, so it is the one this guide uses.

Cost by manuscript length

Here is what the EFA per-word ranges come to at common manuscript lengths.

Word count multiplied by the EFA 2026 per-word range. The EFA gives one range for manuscript assessment, not separate fiction and non-fiction rates. Real quotes vary by editor.

The cost scales in a straight line with length. Every 20,000 words cut before the edit takes $600 to $700 off a fiction developmental edit at these rates, and $800 to $1,000 off non-fiction.

That is not a reason to cut for the sake of the invoice. It is a reason to make the cuts you already know you need before the editor reads the book, not after.

Developmental edit vs manuscript assessment vs line edit

These three get confused, and they are priced differently.

A developmental edit looks at the book as a whole: structure, plot logic, pacing, character arcs and, for non-fiction, the argument. You usually get an editorial letter plus notes in the manuscript tied to specific scenes or sections.

A manuscript assessment (the EFA chart calls it "Manuscript Assessment/Evaluation") asks the same big-picture questions, but usually answers them in a letter without detailed notes on the manuscript. It costs less because it is less hands-on.

A line edit works sentence by sentence: clarity, rhythm, word choice, repetition and voice. It assumes the structure is settled.

Rates from the EFA 2026 rate chart.

Which one fits your draft:

• Choose a manuscript assessment if you want a diagnosis and plan to do the revision yourself, or you are not sure the draft is ready for a full edit.
• Choose a developmental edit if you want detailed, scene-level notes and the draft is as good as you can make it alone.
• Leave the line edit until the structure is settled. For fiction, the EFA chart puts it at nearly the same per-word rate as a developmental edit, so paying to polish chapters you may later cut is expensive.

What pushes the price up

The EFA ranges are a starting point. These are the things that move an individual quote.

Length. Most quotes are per word or built from a word count, so a longer book costs more. Check whether the editor counts from your file or estimates.

Genre and type of book. Non-fiction sits higher on the EFA chart, and editors get through fewer pages an hour. Within fiction, a complex timeline, a large cast or dense world-building can take longer to read carefully.

Turnaround. A rush job usually costs more, because the editor has to move other work to fit you in. Booking ahead gives you more choice of editor.

The editor's experience. Editors with a long track record in your genre can charge above the median. You are paying for pattern recognition that took years to build.

A messy draft. If the timeline contradicts itself, a name changes spelling, or the editor has to reread chapters to follow the plot, those hours land on your bill. A draft that needs a second full pass after a major rewrite costs more again.

When you compare quotes, ask what each one includes: how long the editorial letter is, whether there are notes in the manuscript, whether a follow-up call is included, and whether the editor will look at revised chapters afterwards.

How to prepare so you pay for judgment, not for catching contradictions

An editor's time is the expensive part. An hour spent noticing that Tuesday's meeting happens before Monday's is an hour not spent on whether your second act works.

Before you send the manuscript:

1. Revise it yourself at least once. Read it as a whole, not chapter by chapter, and fix what you can already see.
2. Clean up continuity. Names, ages, eye colors, dates, and who knows what when. Our guide to finding plot holes in your novel walks through how to check.
3. Check that every setup has a payoff. A clue planted in chapter 2 should matter later, or come out.
4. Make sure each scene has a job. If you cannot say what a scene changes, the editor will ask the same question at your expense.
5. Write a short brief. A one-page synopsis, your genre, your intended readers and the two or three problems you already suspect.
6. Confirm the word count. It is the basis of the quote.

If you are not sure the draft is ready, paste up to about 10,000 words into the free Manuscript Readiness Score for a quick check on where it stands.

None of this replaces the edit. It means the editor spends those 36 to 65 hours on the questions only an experienced reader can answer.

Where AI diagnostics fit, and where they do not

AI manuscript analysis is most useful between your last self-edit and the editor's first read. It is not a substitute for the editor.

StoryWith AI reads the manuscript you wrote and answers editorial questions about it. Its analyzers cover story structure, setups and payoffs, pacing and emotional arc, continuity and plot holes, scene purpose and character arcs.

Every finding goes into one ranked list, Book Health, sorted by severity and linked to the exact scene, with a manuscript readiness score on top. It does not write your book.

That makes it suited to the mechanical layer: the contradictions, dropped threads and purposeless scenes you would otherwise pay an editor to find. See AI developmental editing for what the structural pass covers.

Where it does not fit:

• Taste and market judgment. It cannot tell you whether your premise will feel fresh to an agent or acquiring editor.
• Your intent. An unreliable narrator may trip a continuity check on purpose. You decide what counts as a problem.
• A conversation. A developmental editor can talk through the book you are trying to write. Software reports; it does not mentor.
• Real reactions. Simulated reader personas are a first pass, not evidence of how readers will respond.

On cost, the Free plan includes every tool with a one-time AI allowance and no card. On the Author plan ($19 a month), a book-level pass of a 90,000-word novel, with every book-wide analyzer plus a full continuity scan, uses about 18 of its 500 monthly AI text actions. The other plans are on the pricing page.

If your draft is already revised and consistent and you have the budget, going straight to a human editor is a sound choice.

Frequently Asked Questions (FAQ)

How much does a developmental editor cost per word?

The EFA's 2026 rate chart lists 3.0 to 3.5 cents a word for fiction and 4.0 to 5.0 cents for non-fiction. The EFA calls these median rate ranges and says individual members' rates may vary considerably.

How much is a developmental edit for an 80,000-word novel?

At 3.0 to 3.5 cents a word, $2,400 to $2,800. For 80,000 words of non-fiction, the EFA range gives $3,200 to $4,000.

Is a manuscript assessment cheaper than a developmental edit?

Yes. The EFA lists manuscript assessment at 1.5 to 1.8 cents a word, or $1,200 to $1,440 for 80,000 words. You usually get a letter on the big issues rather than detailed notes in the manuscript.

How long does a developmental edit take?

In editing hours, a 90,000-word novel is about 36 to 65 hours at the EFA's 5.5 to 10 pages an hour. Calendar time depends on the editor's schedule, so ask for a start date and a delivery date in the quote.

Why does non-fiction developmental editing cost more?

The rates reflect what editors reported charging, not a set formula. On the EFA chart, editors cover fewer pages an hour on non-fiction (4 to 8, against 5.5 to 10 for fiction), so each page takes more of their time.

Should I book a line edit at the same time?

Usually not. A developmental edit can cut or move whole chapters, so settle the structure first and polish the sentences that survive.

Can AI replace a developmental editor?

No. AI diagnostics can catch contradictions and structural gaps before the edit, which leaves the editor more time for judgment. Taste, market sense and a conversation about the book are still the editor's job.
