Amazon RDS for PostgreSQL Pricing
4 days ago - Dedicated Log Volumes are priced the same as a data volume with 1,000 GiB and 3,000 IOPS and by storage type. Dedicated Log Volumes are only supported in Provisioned IOPS storage. For example, in US East (N. Virginia), an io1 Dedicated Log Volume attached to a Single-AZ instance in RDS for PostgreSQL would cost $0.125 x 1024 GiB plus $0.10 x 3000 IOPS, or $428/month. If you were to run an io1 Dedicated Volume in the same AWS ...

Why is Postgres RDS instance more expensive than SQL Server (license included) RDS instance?
Assuming like me you are using the calculator I think you are missing a couple of important nuances here: Only version available on a t3.micro for SQL Server is express, so you are not paying for any license here. Also only available as single AZ. When you do t4g.micro on RDS PgSQL it defaults to multi-az. When I do apples to apples t3.micro single AZ in us-east-2 for both engines I get approx $13 per month for DB cost for Postgres and $16 per month DB cost for SQL server. If you share source or screenshot of where you are getting your price from might be able to help more. More on reddit.com

r/aws on Reddit: Why is RDS so incredibly expensive
May 23, 2022 -
I created an RDS postgres database with the lowest settings - literally free tier on everything, but apparently I don't qualify for that anymore.
I was never able to figure out how to create a table, put data into it, or connect to it.
However, I was charged $10 a day for a few days, so I killed it and won't be going back. I've had multiple similar experiences with AWS and I never get an explanation for the charged from AWS.
Is there any explanation for this? I use heroku and firebase and never have nearly as much difficulty using those and I've never had a billing issue or random charges.
Update:Here is a detail for the billing. How did this happen?
Update 2:
After feedback here that the costs came from the storage type, I went back and looked at the creation process to see what happened. In selecting the "Easy Create" process for a postgres RDS database, the more expensive storage type was the "default". That's pretty upsetting to me and I really wish that there was something that told you the project cost prior to activation, but at least I figured out what happened. I'm gonna recreate and see if I can't get it cheaper.
Thanks for the help.

Based on the screenshot, the bulk of the charges were from having provisioned iops on an io1 volume, not from the database node itself. If you chose to use a gp2 volume instead the charges would have been significantly cheaper.

r/aws on Reddit: Why is Postgres RDS instance more expensive than SQL Server (license included) RDS instance?
September 5, 2025 -
Question is in the Title. Only reason I'm considering Postgres is because of the "licensing costs" associated with SQL Server. Then I see this. What's up?
Postgres instance would be $86.51 USD:
db.t4g.micro
vCPU: 2
Memory: 1 GiB
SQL Server equivalent instance would be (license included): $67.71 USD
db.t3.micro
vCPU: 2
Memory: 1 GiB
Edit:
For those who asked for more information to better understand my perspective

Go to https://aws.amazon.com/rds/pricing/?p=ft&c=db&refid=e21cc09f-34cd-4d7e-a012-ad97353eb4b4 and go to the "Pricing by Amazon RDS engines" section.

Select either "Amazon RDS for PostgreSQL Pricing" or "Amazon RDS for SQL Server Pricing"
-
Navigate to the "AWS Pricing Calculator" and click "Create your custom estimate now." Select the instance types that I have mentioned above without changing any of the filler info.
