AWS Cost and Usage Report (CUR)
Think of CUR as your AWS itemized receipt, delivered daily to S3. It breaks down charges by hour, product, resource, and tag for spreadsheets or Athena queries. Mid-month numbers are estimates, so do not lock budgets until the report finalizes after invoicing.
AWS Cost and Usage Report is your account's complete itemized ledger, not a dashboard snapshot. It lands in your S3 bucket daily as CSV files, breaking down every dollar by hour, product, resource, and custom tag, ready for Excel or Athena. Engineers use it to attribute costs to teams and analyze granular usage. Each mid-month update is cumulative but estimated, and refunds or support fees can appear days after the month closes, so treating preliminary numbers as final will wreck your chargeback accuracy.
