- Log in to Azure Portal
- Navigate to Azure Resource Graph Explorer
- Use queries to retrieve Azure Cost Advisor Recommendations
- Recommendations where the type refers to Reserved Instances/Capacity will include an annual savings value
- Check the "properties.extendedProperties.term" field to understand which Reservation period the saving applies to
- When querying by RecommendationType be aware of the number of resources that the recommendation is applied to. This can be found in "properties.extendedProperties.targetResourceCount"
- Recommendations where the type refers to Right Size or Shut down will not have an annual savings value. Instead refer to "properties.extendedProperties.targetSku".
- To calculate targetSku costs a separate call will need to be made against the Pricing API: https://docs.microsoft.com/en-us/rest/api/cost-management/retail-prices/azure-retail-prices
