Use the get_cost_and_usage_with_resources API in which you need to add filters to get results on the services you would like to view costs monthly:

  • Actually cost and usage are more granular information but I just want information about total charge for a service in month.

  • You can also get monthly total charge easily lIke this.

    '''python res = boto3.client('ce').get_cost_and_usage( TimePeriod = {"Start": start_day, "End": end_day}, Granularity = "MONTHLY", Metrics = ["UnblendedCost"])

    print(f"TotalCost: {res['ResultsByTime'][0]['Total']['UnblendedCost']['Amount']}") '''

  • I see discrepancy in the amount showed using "cost explorer" vs "billing dashboard" for a month. for ex. in billing dashboard S3 and S3 glacier in total shows 1000 USD but in cost explorer for S3 service it is showing as 1040 USD. There is no difference even unblended, blended or amortized. why is this difference ?
