Dropping to 99p is one of the most common reflexive responses to slow sales, because it is quick, free to implement, and feels like doing something. It is worth separating the genuine question, whether price is actually the constraint on this particular book, from the appeal of a fast, low-effort change. Sometimes price is part of the picture; often it is not the main one.
This guide sets out what a 99p price can realistically be expected to do, what it cannot do, and the royalty mechanics worth understanding before choosing it, so the decision is made with the full picture rather than as a guess.
What a low price can and cannot do
A very low price removes one possible objection: cost. For a reader already interested, on the fence, and comparing several books, 99p can be the nudge that turns browsing into a purchase. That is a real, if limited, effect.
What a low price cannot do is put the book in front of readers who never see it in the first place, or persuade a reader who does see it but is not convinced by the cover, description or sample. If the constraint is discoverability rather than price sensitivity, dropping to 99p mainly reduces the amount earned per copy without changing how many people find the book.
Royalty mechanics at very low prices
At the time of writing, KDP offers different royalty options depending on price and marketplace, and very low prices, including 99p, commonly fall outside the higher royalty band available at moderate price points. This means the amount earned per sale at 99p can be substantially smaller in proportion to the price than at a higher price point, not simply "a smaller number of the same percentage".
It is worth checking the current KDP pricing page directly for the exact bands and delivery cost mechanics that apply in each marketplace, since these are set by Amazon and can change without much notice.
| Price approach | Typical earnings per sale | What it actually tests |
|---|---|---|
| 99p / low-band price | Often reduced, depending on current royalty bands | Whether price was a barrier for readers who already see the book |
| Moderate genre-comparable price | Often higher, depending on current royalty bands | Ongoing sustainable positioning against similar books |
| Short promotional dip | Temporarily reduced, for a defined window | Whether a limited-time low price shifts visibility or reviews during that window |
Retail price, author earnings and value
It helps to keep three things distinct: the retail price a reader pays, the author’s earnings per sale after the retailer’s share and any print or delivery costs, and the value a reader perceives the book to offer. A 99p price changes the first two directly and may or may not change the third. For a book with a strong cover, good reviews and a clear description, 99p can occasionally read as underpricing rather than as a bargain, depending on genre and reader expectations.
If earnings per sale, not just unit count, are the real objective, it is worth doing the arithmetic honestly: a higher unit count at a much lower margin per copy does not always add up to more total income than fewer sales at a higher margin. See our guide on what price to charge for a self-published book for the wider pricing picture, and the self-published author earnings guide for how royalties add up more generally.
When 99p might genuinely make sense
A 99p price is more likely to be worth testing when there is already reasonable traffic to the book’s page but a low conversion rate, and price is the one remaining untested variable after the cover, description and categories have been checked. It can also suit a short, specific promotional window, for example the first book in a series, used deliberately to attract readers into a longer, more sustainably priced sequence.
Example
Imagine the first book in a five-book fantasy series priced at 99p on an ongoing basis, while books two to five are priced at the author’s normal rate. The lead title acts as a deliberate, low-margin entry point, and the later books carry the actual earnings; this is a specific strategic choice, not a default response to slow sales.
It is far less likely to help a standalone book with very low page views, since there is not yet enough traffic for a price change to be tested against.
When it probably will not help
If the book is getting very few views on its product page in the first place, price is unlikely to be the limiting factor, because too few readers are reaching the decision point for price to matter yet. In that situation, discoverability, categories and keywords are usually more useful places to look before touching price at all.
What not to assume
Do
- Check current page views and click-through before assuming price is the constraint.
- Check the current KDP royalty bands for the exact price and marketplace involved.
- Treat 99p as a defined, time-limited test with a clear before-and-after comparison where possible.
Avoid
- Assume a lower price automatically means more total income.
- Change price at the same time as the cover or description.
- Treat 99p as a permanent default without reviewing what it actually achieved.

Common mistakes
- Assuming lower price always means more income. A much smaller margin per copy can outweigh a modest increase in units sold; it is worth doing the arithmetic rather than assuming.
- Dropping price on a book with very low traffic. If very few readers are reaching the page, price is unlikely to be the limiting factor yet.
- Not checking the current royalty band before deciding. Royalty bands can change; a decision based on out-of-date figures may not reflect actual earnings at 99p.
- Changing price and cover or description at the same time. This makes it impossible to know afterwards which change, if any, made a difference.
- Treating 99p as permanent without reviewing it. A price set once and forgotten is a decision made without evidence of whether it worked.
Frequently asked questions
Does 99p guarantee more sales?
No. It can lower a barrier for readers who already see the book, but it does nothing for readers who never reach the page in the first place.
Will I earn less per copy at 99p?
At the time of writing, very low prices commonly fall into a lower KDP royalty band, so earnings per copy are usually reduced; check current KDP pricing documentation for exact figures.
Is 99p ever a sensible permanent price?
It can suit a deliberate entry point into a series, but it is worth checking current royalty bands and reviewing the decision periodically rather than leaving it unexamined.
Should I try 99p before checking anything else?
Generally not. Checking discoverability, cover and description first helps establish whether price is actually the constraint before spending a test on it.
How long should I test a 99p price for?
There is no official figure. A defined period, agreed in advance, with a clear plan for what will be reviewed afterwards, is more useful than an open-ended change.
