Compute Savings Plan for Payer has higher estimated savings than Linked account option, why aren't they the same?

0

Why is the estimated monthly savings for Compute Savings Plan at the Payer Account much higher than the Compute Savings Plan Recommendation when I only change the option to Linked Account?

In my example the options are Savings Plan Type: Compute Savings Plan Recommendation level: Payer Level Savings Plan Term: 1-year Payment Option: All up front Based on the past: 7 Days Estimated Monthly Savings: $12,570.07

VERSUS: Savings Plan Type: Compute Savings Plan Recommendation level: Linked account Savings Plan Term: 1-year Payment Option: All up front Based on the past: 7 Days Estimated Monthly Savings: $665.84

I would expect the Estimated Monthly Savings to be the same.

When you are looking at it from the Payer account, it is estimating savings based on compute usage in every account under that payer (could be 1 to N accounts with lots of EC2). Whereas when you are looking at it from the Linked account, it is estimating the savings for only one specific linked account under the payer (which has far less EC2/compute usage). The estimated savings are far greater when you consider a much larger pool of compute that would be discounted by the savings plan.

Hope this helps.
