Reader-supported writing — what each platform actually takes

Reader-supported writing means readers pay you directly rather than a publication paying you. It is the model behind Substack, Patreon, Ko-fi and Buy Me a Coffee, and the pitch is always the same: cut out the middleman, keep most of the money.

The percentages are real. The trap is that a percentage of a small number is a small number, and almost nobody publishes the small number.

What each platform takes

Read from each company's own pricing page on 6 September 2026:

One flag on Ko-fi: its optional Gold plan, which removes the 5%, is quoted at both $6 and $12 a month across current sources. Check Ko-fi's own page before budgeting for it.

The worked example that matters

On a $5 tip through Buy Me a Coffee: platform takes $0.25, Stripe takes about $0.45, you keep roughly $4.30 — about 86%.

The percentage improves as amounts rise, because Stripe's $0.30 is fixed. On a $50 membership you keep about 91%. On a $1 tip you keep barely half.

Practical consequence: set your minimum tip at $5, not $1 or $3. The fixed fee eats small payments alive.

What Patreon gives you for its 10%

Worth stating fairly, because the 10% looks expensive next to Ko-fi's 0% until you read what it covers. Patreon's own page lists: it handles chargebacks, disputes and fraud; there is no Stripe account to set up; it collects and remits most applicable taxes; and it supports 16+ currencies for both pay-ins and payouts.

That is real administrative work you would otherwise do yourself. Whether it is worth 10% depends entirely on how much you are earning and how much you hate paperwork.

Patreon also offers exportable email lists, which matters more than any fee — see below.

The number nobody puts next to the percentages

Here is the arithmetic that should decide this for you.

On Substack, roughly 90% of newsletters never turn on paid subscriptions at all. Among those that do, independent analyses put median annual earnings around $4,000, with most taking home under $1,000 a month and nearly half earning under $500 in a year.

On Ream Stories, the one platform that publishes an aggregate, creators earned $1.3 million across 15,000+ authors — an average of about $87 per author per year.

So the honest framing is not "Substack takes 10% and Ko-fi takes 0%." It is:

Ten per cent of nothing and nought per cent of nothing are the same number.

The platform fee only starts to matter once you have readers who pay. Getting those readers is the entire problem, and no platform solves it for you.

What actually decides the outcome

You must bring the audience. Every honest account of Substack, Patreon and Ko-fi says the same thing: none of them will find readers for you. Free-to-paid conversion typically runs 3–10%, so 500 paying readers usually means a free list of 5,000–15,000. From cold, that is two to four years.

Pick for the asset, not the rate. The single most valuable feature across all of these is an exportable email list. Substack and Patreon both give you one. That list survives the platform pivoting, dying or changing its terms — and platforms in this category do all three. Mirror shut down; Paragraph left creator publishing entirely; Ream retired the payout route that served most international authors.

Check you can be paid before you build. Substack, Ream and Buy Me a Coffee all route through Stripe, which covers 46 countries. Ko-fi and Patreon support PayPal, which widens it. If you are outside the Stripe list this decides your platform before any fee does — see payment platforms for writers.

How to choose, honestly

If you want tips with the least friction and lowest cost: Ko-fi. 0% on tips is unbeatable and you can add memberships later.

If you want the simplest possible supporter experience: Buy Me a Coffee. The 5% buys genuine simplicity. Fine at small scale, expensive once you are earning consistently.

If you are building a publication with an email list: Substack. The 10% is the highest fee here and the exportable list is worth it. It also now auto-translates posts into 18 languages by default.

If you want tiers, community and no admin: Patreon. The 10% covers tax handling and chargebacks that would otherwise cost you time.

If you write serial fiction and are in one of the 46 Stripe countries: Ream. 10%, no exclusivity, no payout minimum.

The realistic path

Do not start with reader support. Start with commissions.

A single feature at a paying publication — Pellicle pays £375, Geist up to CAD$650 — is worth more than most writers earn from reader support in a year, and it builds the audience that makes reader support viable later. BRYME lists 142 verified paying publications with the rate stated on each.

Run a free Substack alongside it. Build the list. Turn on payments when there is someone to pay you.

Platform fees read from each company's own pricing page on 6 September 2026, except the Ko-fi Gold price, which current sources disagree on and which is flagged rather than quoted. Earnings figures are from independent analyses and platforms' own published aggregates as cited. Fees change — verify before committing.
