MongoDB Atlas
MongoDB Atlas — cost scanning across your clusters and data services
Connect with a read-only Atlas API key. CostSave scans your clusters, data tiers, backups, and network — and flags idle or oversized resources wasting your Atlas spend.
Clusters
Cluster Sizing
  • Over-provisioned — avg CPU <20% and memory <70% over 7 days
  • Idle clusters — avg CPU <5%, <5 connections, near-zero ops/sec
  • Free-tier candidates — M10 with <5% CPU and <0.5 GB disk
  • Over-provisioned storage — disk used <25% of provisioned size
  • Low connection utilization — max connections <5% of tier capacity
Dev clusters
Dev / Test Clusters
  • Cluster name matches test/dev/qa/staging/sandbox/demo patterns
  • Low-traffic clusters matching dev naming
  • Auto-pause disabled on free-tier clusters (M0/M2/M5)
Config
Auto-Scaling & Config
  • Auto-scaling disabled on dedicated clusters (M10+)
  • No VPC peering and no private endpoints on dedicated clusters
  • Cross-region mismatch — cluster region differs from app region
Data Transfer
Data Transfer
  • Multi-region clusters — inter-region replication charges
  • Cross-region transfer cost breakdown
  • Internet egress costs on clusters
  • BI Connector usage and cost
Backups
Backups & Snapshots
  • Excessive backup snapshots — >10 per cluster
  • Continuous backup enabled on idle clusters
  • Backup storage cost per cluster
Operations
Operations Intelligence
  • Read-heavy clusters — ≥90% reads (candidates for replicas)
  • Atlas Search indexes with 0 queries in 30 days
  • App Services functions — unused or 0 invocations
Billing
Billing
  • Current-month vs. previous-month comparison
  • Cost breakdown by cluster and service type
  • Backup cost per cluster
  • Data transfer breakdown — cross-region, egress, VPC/private
  • Monthly trend from paid invoice history
  • Projected full-month cost
