What do 10, 20 or 50 Amazon reviews really cost?
ARC services charge for different things: a review that exists, a download, a reader sign-up, or a month of access. Put in the number of reviews you want and see what each model costs, with the assumptions in your hands.

Assumptions for the others
| Model | Total | Per review | Known in advance? |
|---|---|---|---|
ReadRipple (per verified review) 15 × $5.00, each one verified on Amazon; unfilled reviews refunded | $75 | $5.00 | Yes: you pay per review that exists |
BookSirens Promote (per download) $10 listing + 20 downloads × $2, assuming 75% of downloads review | $50 | $3.33 | No: depends on the review rate |
Hidden Gems (per sign-up, 50 minimum) $20 deposit covers 10 readers, then 40 × $3, assuming 60% of 50 sign-ups review | $140 | $9.33 | No: depends on the review rate |
Subscription service (e.g. Booksprout tier) 2 months × $20; reviews depend on how many reviewers claim the book | $40 | unknown | No: depends on the review rate |
Other services' prices as published on their own sites, November 2026, and they change. The review-rate assumptions are yours to edit; the services do not promise any rate. Subscription tiers vary by service, so the price is an input.
How to read the table
The per-review price is the only number that matters, and only one model lets you know it before you pay. Per-download and per-sign-up services can be cheaper per unit, but the unit is not a review; divide what you paid by the reviews still on your page after 90 days to get the real figure. Subscriptions are cheapest when you release often and the reviewer cap fills every time, and most expensive when a book sits unclaimed for a month you paid for.
