Subscription vs Pay Per Story

Subscription against pay per story is the first real decision a writer makes, because it sets everything else: a pool pays on how much is read, a membership pays whether anything is read or not, and a per-sale royalty pays once. This page compares the three from the writer's side, using the figures each platform publishes.

Updated

Quick answer

  • A pool pays on reading. Kindle+ divides a monthly fund by pages read, with no fixed per-page rate published and ninety-day exclusivity required.
  • A membership pays on commitment. Patreon, Substack, Ream and Ko-fi charge a platform fee on recurring payments that arrive whether a reader opens the story or not.
  • A sale pays once. The stores pay a percentage of a price you set, from 35% to 75% depending on route and conditions.
  • Chapter unlocks sit in between, and the serial apps that use them publish bonus schedules rather than the share itself.
  • The arithmetic below is ours, built only from published rates. None of it is a forecast and none of it comes from an account we hold.

This is the writer's side of a question readers ask too. If you are deciding what to pay for rather than what to publish on, our reader-side pages are subscriptions against credit-based apps and free against paid erotica apps. Everything here is about which way the money reaches the person who wrote the story, under the sourcing rule set out in this section for writers.

Three shapes, and what each one pays on

ShapeWhat triggers the paymentWhere it is published
Subscription poolHow much of your book a subscriber reads, measured in normalised pagesKindle+ through KDP Select
Recurring membershipA reader's monthly or annual payment to you, regardless of readingPatreon, Substack, Ream, Ko-fi memberships
Engagement shareReading and assessed quality, with no rate publishedMedium's Partner Program
Per-sale royaltyOne purchase of one titleThe ebook stores and Draft2Digital
Chapter unlockA reader spending coins, tokens or Ink to open the next chapterGoodNovel, Dreame, Roma, Tapas

The subscription side

Kindle+ is the only true pool in this section. Enrolling in KDP Select puts the ebook in the subscription library, and Amazon's documentation says earnings come from the KDP Select Global Fund, measured in Kindle Edition Normalized Pages, with the rule that you are paid the first time a subscriber reads a given page. It also says it reviews the size of that fund every month, which is the detail that makes planning impossible: the denominator changes and the numerator is everyone else's pages too. There is no fixed per-page rate in the documentation, so any figure you have been quoted is an estimate. The price of entry is ninety-day exclusivity for the ebook, as the Kindle+ page sets out.

Memberships work the other way round. A reader on a Substack or Ream tier pays on a date, not on a page, so the income is smoother and the ceiling is set by how many people will commit rather than by how much they read. All four membership platforms publish their cut: Patreon, Substack and Ream each state 10%, and Ko-fi charges 5% on memberships on its free option. None of them publishes an average earning, and this site will not invent one. Medium is a hybrid that documents neither end: its Partner Program pays from member subscription revenue according to performance and assessed quality, with no percentage and no per-read rate anywhere we read.

The pay-per side

A sale is the simplest thing on this page. You set a price, the store takes its share, you get the rest once. The published rates run from 35% at Amazon's lower option to 75% on Smashwords.com above $2.99, with conditions on nearly all of them, and they are set out in full on how these platforms pay. The appeal is clarity: you can calculate the royalty on a sale before you make it, which is true of nothing else here.

Chapter unlocks look like sales and behave like neither. On the serial apps a reader spends coins, tokens or Ink on one chapter at a time, and what reaches the writer is a share of that spend. GoodNovel describes premium chapters for signed authors paid monthly, Dreame describes a pay-to-read royalty share, and Roma says Authors earn a share of tokens when readers unlock their premium chapters. Not one of the three publishes the share. Tapas is the exception in the group, publishing 100% of reader support after third-party fees and about 70% of ad revenue, while telling creators it cannot promote mature series.

Arithmetic you can actually do

Only the per-sale and membership routes allow real sums, and these are ours, from the published rates alone. A $3.99 ebook pays about $2.79 on a 70% option before any delivery cost is deducted, about $1.40 on a 35% option, and about $2.99 on Smashwords.com at the 75% band. The same book priced at $2.49 drops into the 40% Smashwords.com band and pays about $1.00, which is less than the same book at $2.99 would pay at 75%, about $2.24. That is the sort of cliff edge worth knowing before you choose a price.

On the membership side, a $5 monthly tier on Substack carries the 10% platform fee, $0.50, and Stripe's 2.9% plus $0.30 on a US card, about $0.445, leaving roughly $4.06 before tax. The same $5 on Ream's Direct integration carries the same 10% and the processing figure its help article gives, leaving a similar amount with no payout fee on top. In both cases the fixed $0.30 is the reason small tiers are inefficient: it is 6% of a $5 payment and 1.5% of a $20 one. The fee layers are separated on what the platforms charge.

The pool route allows no arithmetic at all, and that is the honest finding rather than a gap in our research. Amazon publishes the method and not the rate.

What each shape asks of you in return

The money shape sets the work pattern, and two platforms put that in writing. Dreame's basic bonus requires a new chapter published daily with at most two days missed in a calendar month and at least 50,000 eligible words in the month; after a story has claimed the daily update bonus three times, it can keep claiming while that story's pay-to-read earnings for the writer stay above $20 that month. GoodNovel's monthly attendance bonus needs an exclusive book updated with more than 50,000 words across 25 days in a calendar month. Those are publication schedules, not writing targets, and they are the clearest statement anywhere in this section of what a chapter-unlock economy actually wants.

Exclusivity is the other price. KDP Select locks the ebook to the Kindle Store for each ninety-day period, and GoodNovel's exclusive contract means the novel appears nowhere else and hands over translation rights for the signed language version. By contrast Draft2Digital, Apple Books and Ream all state that they require no exclusivity, so a membership or a wide release can run alongside anything else.

Which shape suits which writer

If this is true of youThe shape that fitsWhy, from the published terms
You have finished books and no audience yetPer-sale royalty, sold wideThe rate is knowable in advance and no route except KDP Select asks for exclusivity
You have readers who already follow youRecurring membershipA 10% platform fee on payments that arrive on a date rather than on a page
You write long and readers finish what you writeThe Kindle+ poolIt pays on pages read, so a completed long book earns more than a sampled one, although the rate is not published
You can publish a chapter nearly every dayA serial contractThe published bonuses at Dreame and GoodNovel are built around exactly that cadence
You want to keep every option openPer-sale plus a membershipDraft2Digital, Apple Books and Ream each state that no exclusivity is required

None of those rows is a recommendation about income, because no platform here publishes what a writer earns. They describe the fit between a way of working and a way of being paid. Where each route stands on explicit content is the other half of the decision, on where erotica is banned.

FAQ

Do writers earn more from Kindle+ or from sales?

Unanswerable from published figures. A sale pays a stated percentage of a stated price; Kindle+ pays a share of a fund whose size Amazon says it reviews every month, with no per-page rate published. Anyone who gives you a comparison has filled in the missing number themselves.

What does a $5 subscription actually pay the writer?

On Substack's published rates, about $4.06 before tax, after the 10% platform fee and Stripe's 2.9% plus $0.30 on a US card. That is our arithmetic from its own figures, not a figure Substack states.

Is pay per chapter better than per book?

No platform publishes enough to answer it. GoodNovel, Dreame and Roma all describe a share of coin or token spend without stating the share, so a chapter economy cannot be compared with a royalty you can calculate.

Can I run a subscription and sell books at the same time?

Yes, unless something you signed says otherwise. Draft2Digital, Apple Books and Ream each state that they require no exclusivity. KDP Select and a GoodNovel exclusive contract are the two routes here that would stop you.

Which shape is least work?

On published requirements, a per-sale release, because nothing in a store's terms asks for a publishing cadence. The serial contracts are the opposite: their bonus conditions require near-daily chapters and tens of thousands of words a month.
