Top Sources of Cloud Bill Creep
| Cost Source | Avg YoY Increase | Example | How to Control |
|---|---|---|---|

| Data Egress Fees | +28% | Outbound transfer costs | CDN offloading, egress budgets |
| Overprovisioned Compute | +22% | Oversized EC2 / VMs | Right-size quarterly with Advisor |
| Unused Resources | +18% | Orphaned snapshots, EIPs | Monthly resource audits |
| Logging & Monitoring | +40% | CloudWatch, Log Analytics | Log retention limits, sampling |
| Database Costs | +25% | RDS Multi-AZ scaling up | Read replicas vs. tier upgrades |

Cloud Cost Creep - Frequently Asked Questions
What causes cloud bill creep?
Cloud bill creep is caused by: data storage growing faster than expected (S3, blob storage), data egress/transfer fees on growing traffic, unused or orphaned resources (old EC2 instances, unattached EBS volumes), autoscaling that never scales back down, new services added by developers without cost review, and cloud provider price increases on new resource types.
How much do cloud costs typically grow per year?
Flexera's 2024 State of the Cloud Report found organisations overspend their cloud budgets by an average of 13%, and cloud costs grow 20-35% year-over-year for growing companies. 82% of enterprises report cloud waste from overprovisioned or idle resources. The average organisation wastes 32% of cloud spend.
What are the most common sources of unexpected cloud costs?
Top unexpected cloud cost sources: (1) Data egress fees - AWS charges $0.09/GB out, often hidden in estimates, (2) NAT Gateway costs - $0.045/GB processed, invisible in small deployments but significant at scale, (3) CloudWatch logs storage - accumulates silently, (4) Unused reserved instances - bought for discounts but workloads changed, (5) Multi-region replication - 2-3x storage costs.
How do I stop cloud bill creep?
To control cloud bill creep: (1) Set AWS/Azure/GCP billing alerts at 80% and 100% of budget, (2) Use Cost Explorer or equivalent weekly to find anomalies early, (3) Tag all resources with team/project for accountability, (4) Schedule non-production environments to shut down overnight - saves 60-70% on dev costs, (5) Right-size instances quarterly using AWS Compute Optimizer or Azure Advisor recommendations.
