How can consolidated billing within AWS Organizations help reduce overall costs across multiple accounts?

Intermediate

Answer

Consolidated billing combines the usage from all accounts within an AWS Organization into a single bill, and importantly, it also combines usage across accounts when calculating volume based pricing tiers and applying Reserved Instance or Savings Plan discounts, meaning an organization with many accounts can benefit from better pricing tiers and shared discount coverage that no single account might qualify for on its own.

Real-world example A company with ten separate AWS accounts for different departments benefits from consolidated billing when a single Savings Plan purchased centrally automatically applies its discount to matching usage across all ten accounts, rather than needing a separate plan purchased in each one.
