☁ AWS Cost Calculator

Simulate costs for a lower-traffic copy of your AWS account — compare instance types, Reserved Instances and Savings Plans.

1

Export billing data

Run in your terminal (requires Cost Explorer access):

# Monthly CE export — adjust dates as needed aws ce get-cost-and-usage \ --time-period Start=2026-04-01,End=2026-05-01 \ --granularity MONTHLY \ --metrics "UnblendedCost" "UsageQuantity" \ --group-by Type=DIMENSION,Key=SERVICE Type=DIMENSION,Key=USAGE_TYPE \ --output json > billing_export.json
2

Export discounts (optional but recommended)

Run this command to export active Reserved Instances and Savings Plans to discounts.json:

printf '{"rds_ri":%s,"opensearch_ri":%s,"elasticache_ri":%s,"savings_plans":%s}' \ "$(aws rds describe-reserved-db-instances --output json 2>/dev/null || echo '{}')" \ "$(aws opensearch describe-reserved-instances --output json 2>/dev/null || echo '{}')" \ "$(aws elasticache describe-reserved-cache-nodes --output json 2>/dev/null || echo '{}')" \ "$(aws savingsplans describe-savings-plans --states active --output json 2>/dev/null || echo '{}')" \ > discounts.json
💡 If the new environment will use On-Demand pricing (no RIs yet), the calculator already shows the correct higher OD price for changed items. The current column always reflects your actual billing.
