What's inside.
AWS Savings Plans are simultaneously the simplest and most misused commercial commitment in the AWS portfolio. This white paper documents the full Savings Plans strategy — Compute vs. EC2 Instance plan selection, commitment right-sizing, coverage targets, the conversion from legacy Reserved Instances, and the layering of Savings Plans under an Enterprise Discount Programme. It is built on more than 500 AWS engagements and $2.4 billion in reviewed spend, with specific data on every major plan type across financial services, SaaS, media, retail, healthcare, and AI-native customers.
The most common Savings Plans mistakes are predictable: over-committing on rigid EC2 Instance plans when Compute plans would have been the correct choice; leaving legacy Standard Reserved Instances in place after Savings Plans launched; running 100% coverage targets that defeat the point of Spot and rightsizing programs; and treating Savings Plans as a finance decision when the technical roadmap should dominate. This playbook corrects each of those mistakes with concrete decision frameworks.
The white paper also addresses the harder strategic question: how do Savings Plans interact with an EDP commitment? Most enterprise customers do both — but the order, layering, and sizing matter substantially. We document the right sequence, the right ratio, and the right coverage target at each spend tier.

Built on 500+ engagements.
Every figure, benchmark, and recommendation in this white paper is grounded in primary data from real AWS negotiation engagements. We have advised on more than $2.4 billion in AWS spend across 500+ engagements, spanning financial services, SaaS, media, retail, healthcare, public sector, and AI-native companies. The data set is anonymized and aggregated; no individual customer agreement is identifiable.
This white paper is buyer-side analysis. It is not affiliated with, sponsored by, or reviewed by Amazon Web Services. The recommendations reflect what works in negotiation against AWS's standard playbook, not AWS's preferred customer behavior. Where the two diverge, we have written from the customer's perspective.
