Cloud Cost Optimization 2026: Cut Your AWS Bill by 40%

The Problem Nobody Talks About

The average company wastes 30-35% of cloud spend on unused or over-provisioned resources. Here is how to find and fix it systematically.

Step 1: Find Where Money Goes

aws ce get-cost-and-usage \
  --time-period Start=2026-01-01,End=2026-01-31 \
  --granularity MONTHLY --metrics BlendedCost \
  --group-by Type=DIMENSION,Key=SERVICE
# Typical: EC2 40-50%, RDS 20-25%, Data transfer 10-15%

Step 2: Right-Size Instances

Instances below 20% average CPU are candidates for downsizing. An m5.xlarge at 15% CPU should be t3.large — 40% cost reduction. Use AWS Compute Optimizer for automated recommendations.

Step 3: Reserved Instances

For instances running 1+ years, reservations are mandatory — on-demand for those is just waste.
