Readium LCP

LCP Pricing
In this section, we’ll detail the Readium LCP pricing model.
Our pricing structure is dual:
- A “volume-based” pricing on LCP Server fees for organisations that do not have a considerable annual revenue from digital products, but generate more than 1 million licenses per year.
- A “revenue-based” pricing on LCP Client fees for all organisations, and LCP Server fees for organisations that are not volume-based. This is a tiered-pricing structure based on their annual revenue from digital products.
The following tables outline the pricing model that will be applied to new LCP integrations starting in March 2025 and to existing customers from January 2026.
Volume-based pricing
This pricing is used for companies that have an annual revenue from digital products of less than 15 million euros.
Class | Server |
---|---|
F – more than 1 M licenses | 18,000 |
G – more than 2 M licenses | 36,000 |
H – more than 4 M licenses | 60,000 |
I – more than 10 M licenses | tbn |
All prices are in €, before VAT.

Key Points
- Volume-based pricing: This model has been created to mitigate the effects of small to medium organisations distributing LCP licenses on behalf of large libraries and e-book vendors.
- Revenue-based pricing: The fee structure is determined by the client organisation’s annual gross revenue from digital products. Digital products are ebooks, audiobooks and other types of publications, distributed with or without DRM.
- Annual fee structure: All listed fees are charged annually as of the date of signature of the contract and are exclusive of taxes.
- Predictable updates: Prices are reviewed every two years, with changes announced six months prior to their application in January of the following year.
Additional Applications
This applies to extra applications, built and deployed by the same organisation after the first one has been fully certified:
- Mobile applications: 20% of the base fee per additional application or a Class A fee, whichever is higher.
- Thorium fork or customization: 50% of the base fee per additional fork/customization.
- Hardware: No additional charges per extra device.
Discount for Low-income Countries
We are committed to accessibility and affordability for companies in low-income countries. Members in Class A and B belonging to countries listed in our official list of low-income countries receive a 50% rebate on the total certification cost.
