Measurements and reference values
- Atlas Flex has a built-in maximum charge of $30 per cluster for 30 days of continuous usage. The $8 base tier includes 5 GB storage, 100 operations per second, and unlimited data transfer; the published hourly rates rise by usage band to $30 per 30 days at 400–500 operations per second. (high confidence) (verified as of 2026-10-21) [source]
Problems, failure modes and limitations
- Atlas documents the $30 ceiling as a built-in Flex pricing limit, not as a customer-set dollar budget. The published price schedule ends at 500 operations per second and the Flex limits documentation describes fixed service limits; these pages do not document a configurable per-cluster spend-stop amount. (medium confidence) (verified as of 2026-10-21) [source]
- The $30 monthly ceiling does not buy higher Flex throughput beyond 500 operations per second. Atlas applies a separate hard throughput limit above 500 ops/sec and may queue operations; the cost guide recommends considering a Dedicated cluster when a workload consistently reaches Flex throughput or storage limits. (high confidence) (verified as of 2026-10-21) [source]
Comparisons and alternatives
- Flex pricing stops at 500 operations per second. Atlas treats throughput above that as a hard limit and applies per-connection cooldowns and queues, rather than billing a higher Flex tier. (high confidence) (verified as of 2026-10-21) [source]
Facts and statements
- MongoDB currently lists Flex cluster pricing from $8 to $30 per 30 days, billed hourly. Its five monthly-equivalent totals are $8, $15, $21, $26, and $30; the $30 band covers 400–500 operations per second. (high confidence) (verified as of 2026-10-21) [source]
- The $30 maximum applies to a Flex cluster's priced usage, not an Atlas organization-wide spend quota. Atlas bills organizations across projects, deployments, and services, and defines invoice Total Cost as billed usage plus taxes, so the full invoice can exceed $30. (high confidence) (verified as of 2026-10-21) [source]
- A historical MongoDB forum thread asked whether the $8 Flex base price applied per organization or per cluster. A respondent answered that it was per cluster, and the original poster considered consolidating lightly used clusters. (low confidence) [source]
