Yeah, tack on another $115 or so for the 1TB of storage. And as a sibling comment mentions, on-demand pricing means it isn't really an apples-to-apples comparison. In almost every case other than a hobby project it feels like the convenience of RDS vastly outweighs the savings of ~$250 you'd get by self-hosting.

> for ~$188/month.

Note that this is still the on-demand price.

Although it's still not Apple to Apple, no one (sane) would useRDS 24x7 without RI. That probably brings you down another 50 bucks or so.

$188 without storage and bandwidth.

The t4g instances are also burstable so running your database with 4 cores under load would either get you throttled or produce more charges.

and the price excludes the 1.5 TB EBS volume
