How much does book marketing cost? Real numbers for authors (2026)

That's the honest short answer. I'm JD Caron; I run Weekend Publisher, a book marketing service for science fiction and fantasy authors, and unlike most of this industry, I publish my prices. This guide covers what everything actually costs in 2026, what the money buys, and, more useful than either, how to know whether you should be spending it at all.

The market at a glance

Two things worth noticing in that table. First, the spread is enormous: three orders of magnitude between a newsletter promo and an agency campaign. Second, most services at the top end don't publish prices at all; you find out on a sales call. If you have to get on a call to hear the number, budget for the number being big.

What the money actually buys

• Facebook ads are the main engine for fiction, that's what the spend data across my 350+ authors shows, not a guess. You can technically start at $5/day. Realistically, testing creative properly (I typically test 10 to 12 ad variations per book) takes $10 to $30/day for a few weeks before you know anything. A funded, ongoing campaign for a series usually lands at $500 to $1,500/month in spend, separate from any management fee.
• Amazon ads are support, not the star. Clicks are cheaper to understand but harder to profit from for most fiction. Where they shine is data: a few weeks of Amazon category and keyword ads is a cheap recce mission that tells you how your book converts before you scale spend elsewhere.
• BookBub Featured Deals are the lottery ticket that's actually worth buying, when you can get one. Pricing runs from around $113 for a low-priced niche freebie to nearly $4,000 for a full-price deal in a giant category; crime fiction, with 3.2 million subscribers, runs about $782. The catch is acceptance: most submissions are rejected, so nobody should build a plan around one.
• Newsletter promos and price-promotion sites ($15 to $499 a slot) are the cheapest real lever. Stacked around a discount, they can spike your sales rank. What they don't do is build the durable ad system that keeps selling books in month six.
• Services (freelancers, coaches, agencies) are where the ranges get wide and the value gets uneven. A freelance marketer on a project basis averages $570 to $1,320 depending on scope. Agencies charge $3,500 to $35,000+ for campaigns. Publicists run $1,500 to $10,000 and mostly buy media attention, which sells far fewer novels than authors hope. The honest question isn't "what does it cost," it's "what does it return," which brings me to the number this industry doesn't talk about.

The number that actually matters: cost per new reader

Here's how I evaluate every dollar my clients spend. Not clicks, clicks don't mean much on their own. Not even day-one sales. The question is: what does it cost you to acquire a new reader, and what is a new reader worth to you?

Across the SFF accounts I manage, acquiring a new reader through Facebook ads typically costs $2 to $7. One honest caveat: that range is only achievable when the ads and your Amazon product page are both set up right, send great traffic to a weak page and the number climbs fast. Whether that's a bargain or a disaster depends entirely on your backlist. If you have one standalone book netting $3.50 a sale, a $5 reader is a losing trade. If you have a six-book series where a hooked reader goes on to buy books two through six, or reads them all in Kindle Unlimited, that same $5 reader might be worth $15 to $25 to you. Same ad. Same cost. Opposite outcome.

That's why the real answer to "how much does book marketing cost" is: it depends on how many books you have. Paid marketing usually becomes profitable around book three of a series. One of my clients came to me losing $60 a month on his ads; after rebuilding his campaigns around series read-through, $553/month in spend now returns $1,332 in revenue, a $779/month profit. The books didn't change. The math did.

What I charge (and why it's published)

Most services in this industry make you get on a call to hear a price. I think that's backwards, so here's mine:

• The Readership Engine, $1,997. Six months of group coaching for authors who want to run their own ads: weekly live sessions, open office hours, a full video library, and custom tracking software. Ad spend is separate and yours to control; most members run $300 to $1,500/month. And that spend isn't money out the door: when the system is working, royalties are flowing back in while you learn.
• Done-for-you ads management, from $4,000. I build and run the campaigns; you write the next book.

Am I the cheapest option in the table above? No. A newsletter promo costs less than lunch with me. But compare against what agencies charge for generic "book marketing," $7,500 to $15,000+ by their own published guides, and I'm the specialist option at half the generalist price. That's not a sales line; it's arithmetic.

When you shouldn't spend money on marketing

I'd rather tell you the truth than sell you a fantasy, so here's the section most cost guides skip:

• One standalone book and a small budget? Don't hire anyone, including me. The math above almost never works on a single title. Spend $50 to $150 on newsletter promos around a price drop, put the rest into writing book two, and come back when the series exists.
• Book isn't positioned yet? If your cover, blurb, and category don't match what's selling in your genre, ads will only make the mismatch more expensive. Fix positioning first; it's cheaper than paying to send traffic to a page that doesn't convert.
• Tempted by the big-invoice route? I once had an author come to me after paying a marketing firm over $10,000; the result was one recorded sale. Nobody should learn pricing that way. If a service won't tell you what specifically they'll do, what it costs, and how you'll measure whether it worked, keep your card in your wallet.

Costs for sci-fi and fantasy specifically

Genre changes the numbers more than most guides admit. SFF readers are voracious series readers and heavy Kindle Unlimited users, which pushes the value side of the equation up: read-through and page reads make an SFF reader worth more than the day-one sale suggests. On the cost side, SFF ad audiences on Facebook are large and well-defined (comp-author targeting works beautifully), which keeps cost per new reader in that $2 to $7 band (again, assuming the ads and the Amazon page are dialed in). The practical upshot: a fantasy author with a three-book series and $500/month has a realistic shot at profitable ads. A literary standalone with the same budget mostly doesn't. It's not fairness, it's just the math. For the full playbook, see how I run Facebook ads for sci-fi and fantasy novels.
