Ghostwriting Rate Calculator for Book Quotes
Describe the book and your hourly goal. Get the hours by phase, a project fee, per-word view, milestone payments and a paragraph explaining the price.
River's ghostwriting pricing calculator turns a project description and your own rate into a quote you can defend. Describe the book, memoir or content series, and give your hourly target or the income you need from a year of work. River estimates the hours for each phase, from interviews and research to drafting, revisions and project management. It converts them into a flat fee, shows the per-word equivalent, sets milestone payments and offers two or three scope options. Every estimate is visible, so you can change any of them.
Most answers to how much a ghostwriter costs are ranges quoted from surveys and agency price lists, often spanning tens of thousands of dollars. They cannot tell you what this project should cost from you, because the range hides the variables that matter: how many interviews, how much the client already has on paper, how many revision rounds and how fast they reply. This builds the price from those variables and your own rate, so the number follows from the work rather than from a guess.
It is for freelance ghostwriters and small agencies quoting a new book or content series, and for writers raising rates who want the reasoning on paper. Use it after the discovery call and before you send a number. The result includes a short paragraph explaining the fee that you can drop into your ghostwriting proposal. Consultants pricing advisory work by the day will find the consulting rate calculator a closer fit.
How to price a ghostwriting project from the work
Start with hours, not words. A book built from interviews spends its time in places the word count hides: preparing for and holding interviews, reviewing transcripts, outlining, drafting, revising and managing the client. As an illustration only, a 50,000-word business book with ten interviews might take 40 hours of interviews and preparation, 30 of outlining, 250 of drafting and 80 of revisions and management. Your numbers will differ, which is why the calculator shows each line rather than one total.
Then decide what an hour is worth. Divide the income you need from your writing, plus business costs and taxes, by the hours you can realistically bill in a year. In the US, those taxes include self-employment tax of 15.3% for Social Security and Medicare. For a solo writer that is often far fewer than a full-time schedule, because marketing, admin and gaps between projects take real time. If you need $90,000 before costs and can bill 1,100 hours, the floor is about $82 an hour. Price below that and every project quietly loses money.
Finally, quote a flat project fee rather than hours. Clients compare totals, and a flat fee rewards you for getting faster instead of penalising you. Build in a buffer for the unknowns, such as a client who rewrites chapters themselves or adds a co-founder's voice midway, and spell out what triggers extra fees. Tie payments to milestones the client can see. Showing the per-word equivalent still helps, because many clients have seen per-word figures elsewhere and want to compare.

Common questions
How much does a ghostwriter charge for a book?
It varies too widely for a single answer to help you. Fees depend on length, interviews, research, revision rounds, deadline and the writer's experience, and published ranges span tens of thousands of dollars. This calculator builds your price from those factors and your own hourly target, so you can quote a number you can explain line by line.
Should I charge per word or per project?
Per project, in most cases. A flat fee tied to a defined scope is easier for clients to approve and rewards you for working efficiently. Per-word pricing suits short, predictable pieces such as articles. River still shows the per-word equivalent of your project fee, because clients often compare it against per-word figures they have seen elsewhere.
What if the client says the price is too high?
Change the scope, not the rate. Offer fewer interviews, a shorter book, one revision round instead of two, or a book built partly from the client's existing talks and articles. The scope options in your quote exist for exactly this conversation, so you can lower the price by removing work rather than by agreeing to work for less.
Does it use market rates for ghostwriting?
Not unless you ask, and then only from sources it can link. Market surveys mix very different projects and writers, so a quoted average can mislead more than it helps. River prices from your own rate and the hours the project needs. If you want a comparison, ask in chat and it will look up current published figures and cite them.
How should the payments be scheduled?
Tie them to milestones the client can see. A common pattern is a deposit on signing, then payments on an approved outline, a delivered full draft and the final manuscript. That keeps cash coming in while the work happens and means a stalled project has already paid for the work done. River proposes a schedule you can adjust, and the ghostwriting contract generator writes it into the agreement.
