Estimate cloud run-rate savings from rightsizing, commitment discounts, storage optimization, and network and egress controls. Use conservative inputs and validate with billing trend after controls are installed.

Estimated percent of cloud spend that is network and egress.
Percent of compute spend eligible to be covered by commitment discounts.
Average discount percent achieved on the covered compute spend.
Percent savings achievable on compute spend via rightsizing and idle cleanup.
Percent savings on storage spend from cleanup and tiering.
Percent savings on network spend from routing, caching, and egress controls.
Cost to implement controls. Used for payback.
Used in memo output.
Optional context for stakeholders.
Assumptions
Fix validation errors to generate results.
1) Enter annual cloud spend and a simple spend split (compute, storage, network).
2) Enter conservative savings assumptions for each lever.
3) Generate results to view savings breakdown and payback.
4) Copy or download the memo and export a one-row CSV for Finance.
- Rightsizing savings: savings from downsizing overprovisioned compute and removing idle instances.
- Commitment savings: savings from applying commitment discounts to the stable portion of compute.
- Storage savings: savings from cleanup and tiering.
- Network and egress savings: savings from routing, caching, and egress controls.
- Payback: implementation cost divided by ongoing monthly savings (if implementation cost is provided).
- Double counting: rightsizing and commitments can overlap; keep assumptions conservative.
- Bad spend splits: compute + storage + network cannot exceed 100 percent.
- Over-committing: commitment savings assumes stable workloads and disciplined coverage management.
- No ownership: savings do not stick without tagging and cost ownership.
- Rightsizing: reducing overprovisioned resources to match actual usage.
- Commitment coverage: the percent of compute spend you can safely discount via commitments.
- Egress: data leaving the cloud provider network that often drives unexpected cost.
