Serverless instances offer pay-per-operation pricing, meaning that you only pay for the Processing Units consumed by your database operations and storage consumed by your data and indexes. You do not need to specify a cluster size since serverless instances seamlessly scale to accommodate changes in workload traffic.
Serverless instances may be more cost effective for applications with low or intermittent traffic. To learn more about serverless instances and use cases, see Choose a Database Deployment Type.
Operation pricing varies between cloud providers and geographic regions. All operations are billed per day.
Read Processing Unit (
Read operations to the database.
You are charged one
If a document exceeds 4KB or an index exceeds 256B, Atlas
covers each excess chunk of 4KB or 256B with an additional
Write Processing Unit (
Write operations to the database.
You are charged one
If a document and index exceed 1KB, Atlas covers each excess
chunk of 1KB with an additional
Range from $0.90 to $2.20 per million
Logical document and index storage. This value includes the number of bytes of all uncompressed BSON documents stored in all collections, plus the bytes stored in their associated indexes.
Range from $0.20 to $0.70 per
Point-in-Time backups triggered by write events.
Range from $0.20 to $0.60 per
Restore from Backup
The time required to restore your serverless instance.
Data transfer as part of the backup and restore process is charged separately.
Range from $2.50 to $6.00 per restore hour.

The price for each million (MM)
RPUs depends on volume of reads
RPUs start at 0 each day. Prices are in cascading
The first 50 million
$0.09 to $0.22/MM
The next 500 million
$0.05 to $0.11/MM
550 MM-20.55 B
The next 20 billion
$0.01 to $0.03/MM
If your application uses 560 million
RPUs in a day, in a region
with prices of $0.10/MM, $0.06/MM, and $0.02/MM by tier, Atlas
charges you $35.20:
$0.10/MM for the first 50 million ($5.00).
$0.06/MM for the next 500 million ($30.00).
$0.02/MM for the last 10 million ($0.20).
If that usage is typical for a day, your application costs approximately $1056 per month ($35.20 per day x 30 days).
In another example, if your application uses 0.5 million
in a day in the same region, Atlas charges you $0.05:
$0.10/MM for the first 0.5 million ($0.05).
If that usage is typical for a day, your application costs approximately $1.50 per month ($0.05 per day x 30 days).
An unexpected, significant increase in serverless instance usage could result in an expensive invoice. Use billing alerts to monitor usage.
