A subscription is not a pricing decision. It is a promise to keep working, made to people who will notice if you stop. The arithmetic always favours recurring revenue; the question is whether you can carry the obligation that comes attached, for years, on your own.
Most of the advice here skips that part because the arithmetic is more fun to write about.
What does the arithmetic actually say?
That recurring wins, obviously, and by a lot.
Take a €20 product against a €5 a month subscription. The subscription draws level in month four, passes the one-off in month five and never looks back — assuming nobody leaves.
| Monthly churn | Average months a subscriber stays | Lifetime value at €5/month |
|---|---|---|
| 3% | ~33 | €167 |
| 5% | ~20 | €100 |
| 10% | ~10 | €50 |
| 15% | ~7 | €33 |
The spread between the top and bottom row is five times, which is larger than any pricing decision you will make. And you do not get to choose the row — it is chosen by whether the thing keeps being worth paying for.
That is the whole subject, compressed: a subscription converts a product problem into a consistency problem.
What does the obligation actually feel like?
Monthly, and public.
A one-off sale concludes. The customer has the file, you have the money, and if you take three weeks off nobody is harmed. A subscription has a renewal date for every single customer, staggered across the month, each one a small moment where they ask whether this is still worth it.
The month you ship nothing, they all ask it at once.
For a business of one, that is the real cost: not the support load, but that your worst month is now visible to everyone who pays you, and arrives on a schedule set by them rather than by you.

When is a subscription clearly right?
When the thing genuinely changes.
- Prices and tools move. A maintained list is worth paying for monthly precisely because it goes stale. That is honest recurring value.
- The output is ongoing. Access to new material each month, where "each month" is a rhythm you already have.
- The value is access, not artefacts. A community, answers to questions, a thing that is useful because it is live.
The test: if you published nothing for two months, would a subscriber still be getting something they would miss? If yes, it is a subscription. If no, it is a product with a payment plan, and buyers work that out faster than you would like.
When is it clearly wrong?
When you do not already have the rhythm.
A subscription will not create a monthly habit you do not have. It will add an audience that watches you not have one. If you are not currently shipping something every month without anyone paying you to, the subscription is a commitment device that mostly commits you to guilt.
Also wrong when the catalogue is finished. Eight books that are done are eight products, not a subscription. Charging monthly for a fixed library is the thing buyers feel most cheated by, because the second month is identical to the first.
Can you do both?
Usually, and it is the best answer.
The clean split: the product is the one-off, the subscription is what comes next. The playbooks here are €20 each and a bundle is €50 — and the strongest version of that bundle is the one that includes everything added for the next twelve months.
That last form is worth noticing. It gives the buyer the upside of recurring access and gives you a defined end to the obligation. You can renew it, but you are not promising indefinitely at the moment you have the least idea what indefinitely costs.
| Model | You promise | They get |
|---|---|---|
| One-off | nothing further | a finished thing |
| Twelve-month inclusion | a year of additions | upside, with an end date |
| Open-ended subscription | forever | access while they pay |
The middle row is the one most small sellers should be in and the one least often chosen, because it is less impressive in a pitch.
What about the affiliate version of this question?
Same structure, opposite side of the table. Most affiliate programmes pay once; a few pay on every renewal, and the difference over a year is not close. Recurring affiliate income, and why most of it is not covers that, and it is the cheapest way to get recurring revenue without taking on a delivery obligation of your own.
Where these numbers came from
The lifetime-value table is arithmetic, not measurement: average lifetime in months is approximately one divided by the monthly churn rate, multiplied by the monthly price. Churn rates are illustrative, chosen to show the spread rather than to predict yours.
The €20 and €50 figures are this site's actual prices as of 19 October 2026. Bundle or single covers the catalogue side of the same decision.
The Affiliate Playbook is the one about recurring income specifically.

Questions people ask
Is a subscription better than a one-off product?
It earns more per customer and costs more to keep. A one-off sale ends when the file is delivered; a subscription means every month you have to have added something, forever, or people leave and say why in public.
What churn rate should you expect?
Rather than guess, work out what you can survive. At 5% monthly churn the average subscriber stays about 20 months; at 10% it is about 10. Both are plausible for a small product, which is a wide enough range that planning on the optimistic one is a mistake.
Can you sell both?
Yes, and it is usually the right answer: the product is the one-off and the subscription is the updates, the community or the new material. What does not work is selling the same thing twice under two labels.
When should you not start a subscription?
When you do not already have a monthly rhythm. If you are not publishing something every month now, a subscription will not create the habit — it will add an audience watching you fail to have one.
Does recurring revenue make a business more valuable?
It makes it more predictable, which is not the same thing. Predictable revenue with an obligation attached is worth less than people assume when the obligation is one person's time.
What is the smallest honest version of a subscription?
A bundle that includes everything added for a fixed period, like twelve months. It gives the buyer the upside of recurring access and gives you a defined end to the obligation.
