Amazon Relational Database Service Backup Storage

Question

hello community, I am currently using free tier of the AWS, in that I am using the AWS RDS service.. But still I don't know why i charged for the "USD 0.09 per GB-month of backup storage exceeding free allocation" and "
$0.09 per additional GB-month of backup storage exceeding free allocation running PostgreSQL" even though I have deleted the Snapshots of the DB and also deleted all the RDS databases which I have created. can anyone please help me with this.....please.....

Answer

Hello.

Charges already recorded on your bill will not disappear.  
Also, did you check the regional snapshot listed on your bill?  
You can also use CostExplorer to find storage prices for RDS.  
If you search for "RDS: Storage" and find that charges are incurred every day, there is a high possibility that snapshots remain.
