How to choose the right reserved instance in Azure

useruk1, thanks for the question. Unfortunately, the break even point for Savings Plans is much more complex to calculate due to the dynamic nature and broad resource type/SKU reach of this commitment type. When you commit to a Savings Plan hourly usage (let's say 5 USD/hour), it will be consumed according to each eligible on-demand usage (Virtual Machines, Azure Container Instances, Azure Functions Premium, etc.) at Savings Plan rates. Savings Plans hourly commitments are deducted starting with the highest discounted usage first (different resource types/SKUs get different discounts). See more details here. As usage can be very dynamic, we cannot easily anticipate which resources are going to benefit from the Savings Plan nor the average discount during the Savings Plan term.
