Real-World Prometheus Cost Examples
Self-Hosted Small Team (10 services)
$50$50–$100/month
A 10-person startup self-hosting Prometheus on a single t3.xlarge EC2 instance with EBS storage, monitoring 10 services with ~50M samples/month. No long-term storage, 15-day local retention.
Self-Hosted Production (High Availability)
$400$400–$800/month
A mid-size engineering team running 3x r5.large EC2 instances with Thanos for long-term S3 storage, monitoring a Kubernetes cluster with ~500M samples/month and 90-day retention.
Grafana Cloud Free Tier
$0$0/month
A small team monitoring a few microservices using Grafana Cloud's hosted Prometheus with up to 10,000 active series and 14-day retention. No infrastructure to manage.
AWS Managed Prometheus (Medium Kubernetes Cluster)
$90$90–$150/month
An AWS-native team running EKS with ~1 billion metric samples/month, using AMP for fully managed Prometheus with no infrastructure overhead and PromQL querying via Grafana.
Google Cloud Managed Prometheus (Large Kubernetes)
$300$300–$400/month
A GCP team running 5 GKE clusters generating ~5 billion samples/month across all services. Google charges $0.06 per million samples with no storage fees, plus read API costs.
Enterprise Scale (Chronosphere / Sysdig)
$2,000$2,000–$5,000/month
A large enterprise with 50+ services, millions of active series, multi-tenancy requirements, and compliance needs. Typically includes dedicated support, cardinality management, and custom SLA.
Small Team: Self-Hosted Infrastructure Only
$1,800$1,800/year ($150/month)
Single Prometheus instance on a t3.xlarge equivalent, scraping 105k samples every 10 seconds, no HA or redundancy. Infrastructure cost only — excludes engineering labor.
HN community comment (2021-09-30)Small Team: Self-Hosted Total Cost of Ownership
$21,800$21,800/year ($20,000 engineering + $1,800 infrastructure)
Self-hosted Prometheus with a junior engineer at 25% time for maintenance and operations. Represents realistic TCO for a startup running their own monitoring stack.
Reddit r/googlecloud community comment (2025-03-19)Moderate Scale: AWS Managed Service for Prometheus
$18,000$18,000+/year ($1,500/month before storage and query costs)
Equivalent monitoring to a 105k-samples/10s self-hosted setup using AWS Managed Service for Prometheus starting at $90/month. Actual costs scale with metric volume and query load.
