Calculation for Compute Savings Plan
0
Hi, question about Compute Savings Plan calculation:
I try to come up with some numbers and I'm not sure if I'm doing this right, so it would be great if someone could confirm. Let's say for example I have m5.xlarge instances that are all on-demand, and I pay currently $3000 per month for them.
I'd like to purchase a Compute Savings Plan, 3 years, no upfront for them and commit $1 per hour. According to https://aws.amazon.com/savingsplans/compute-pricing/ m5.xlarge has 40% savings over on-demand for that.
On-Demand cost 3 years: $3000 * 36 = $108000
Commit $1: $1 * 24 * 30.5 * 36 = $26352
$108000 * 0.6 = $64800
$64800 - $26352 = $38448
$38448 * (10/6) = $64080
$64080 + $26352 = $90432
Meaning over 3 years, I pay $90432 instead of $108000, because the m5.xlarge instances are billed with only 60% of their on-demand cost until my committed $1/h is used up. Is that correct or did I misunderstand how that's supposed to work?

I suggest using the pricing calculator to compare the difference between different saving plans options.
I put in a simple m5.xlarge server on a 3 year no upfront here. You can easily expand the calculations and change the options to compare
Thanks for your reply. My problem is, I need to come up with suggestions like "if we commit to spend $A over 3 years, we save $B, if we spend $C, we save $D". https://us-east-1.console.aws.amazon.com/cost-management/home?region=eu-central-1#/savings-plans/purchase allows me to purchase custom commitments, I just need to know first if I calculate it correctly.
