Credit cost & pricing

How does it work?

coherence's pricing is designed to be accessible for all developers, ranging from indie developers to AAA game studios.

Our platform helps you utilize compute resources efficiently in order to minimize wasteful spend. We know that forecasting cloud costs can be daunting, so coherence provides different subscription plans for different requirements, and the flexibility to change plans at any time, or purchase additional credits to deal with short term bursts or spikes in the number of users.

coherence uses our own in-house virtual credit system to keep track of costs.

Some basic facts:

• There are no hard limits (like max CCU, max bandwidth, etc.). The amount of resources you have is defined by the amount of credits you have.

• Credits renew every month. You get again the full amount of credits based on the tier you're on.

• If you need more credits, you can purchase them for a fee, or move to a different tier.

• You can move tier every month, if you want.

• Unused credits don't move over to the following month.

Why credits?

Since no two games are identical in their use of cloud resources, credits give you the flexibility you need for your Unity multiplayer game. Whether you’re building a platformer, a virtual DJ venue, a racing sim game or the next big MMO, our credit system makes sure your project gets maximum value and usage out of your chosen tier!

Credits explained

Credits are coherence’s virtual unit of cost that can be converted into resources. Use the table below to understand exactly what costs a certain amount of credits:

Detailed explanations of these terms are available in our Glossary.

Calculating credit costs

Rooms

The cost for a game session in a room based game is calculated easily as follows:

sessionCreditCost = maxPlayers * sessionLength / 60 + sessionBandwidthGB * 200

Where:

• sessionLength = the maximum duration of a game session in minutes

• maxPlayers = the maximum number of players that can join a game session

• sessionBandwidthGB = total outbound bandwidth in GB

Example

Sessions per month = 150,000

Max players per session = 12

Max length of a session = 10 minutes

Outbound bandwidth per session = 2.5 MB

sessionCreditCost = (12 * 2 / 60 + 2.5 / 1000 * 200) * 150000 = 135,000 credits

150K sessions would cost approximately 135K credits.

Worlds

It's equally simple to calculate the cost for a persistent world that is online 24/7:

worldCreditCost = (worldSize * 24 * 30) + (averageHourlyTrafficGB * 24 * 30) * 200

Where:

• worldSize = the maximum number of players that the world can host

• averageHourlyTrafficGB = the average outbound bandwidth consumed hourly by the world

Example

Number of worlds online = 3 (24/7, eg. NA, EU, Asia)

Max players per the world = 250

Average outbound bandwidth per hour = 95 MB

worldCreditCost = ((250 * 24 * 30) + ((95 / 1000) * 24 * 30) * 200) * 3 = 581,040 Credits

Hosting three worlds for up to 250 players would cost approximately 580K Credits.

Simulators

To calculate costs for a Simulator you need to understand how many Simulator instances you require, and for how long they will be online. For Room-based games, credit costs can be calculated with the following formula:

totalSimCost = (timeOnlinePerInstance / 60) * (simInstanceCost * simUtilisationPerSession)

Example

simUtilisationPerSession = 0.5 (one instance for 2 concurrent sessions)

timeOnlinePerInstance = 10 (sessionLength of room example above)

simInstanceCost = 40 (medium sim)

totalSimCost (per session) = (2 / 60) * (40 * 0.5) =  0.7 credits

Simulator support for 50K sessions would cost approximately 35K Credits.

Billing

Every month we calculate your credit cost based on the total consumption of CCU hours and bandwidth. Before we calculate the total credit cost based on the aforementioned formulas, we deduct the included CCU hours and bandwidth in your plan.

The base subscription fee will be invoiced at the beginning of the month. If you exceed your limits and require additional credits, these will be invoiced with a separate invoice at the end of the month.

Limits and caveats

• Individual Rooms are limited to 100 CCUs. The total number of Rooms is unlimited provided the credit usage stays within plan limits but there's a limit of 1000 CCUs across all rooms.

• Individual Worlds are limited to 1000 CCUs. The total number of Worlds is unlimited provided that the credit usage is within plan limits but there's a limit of 1000 CCUs across all worlds.

• Enterprise customers can negotiate custom sizes and limits for both Rooms and Worlds.

• Costs per session or World will increase if additional features such as Simulators or KV-Store are utilized.

• Each plan comes with a maximum amount of purchasable extra credits. Exceeding that limit will result in throttling CCUs and an extra charge at the end of the billing cycle for features that can't be throttled like storage.
