Manage Disk size usage
What you are charged for
Each database has a dedicated disk. You are charged for the provisioned disk size.
Disk size is not relevant for the Free Plan. Instead Free Plan customers are limited by Database size.
How charges are calculated
Disk size is charged by Gigabyte-Hours (GB-Hrs). 1 GB-Hr represents 1 GB being provisioned for 1 hour. For example, having 10 GB provisioned for 5 hours results in 50 GB-Hrs (10 GB × 5 hours).
Usage on your invoice
Usage is shown as "Disk Size GB-Hrs" on your invoice.
Pricing
Pricing depends on the disk type, with gp3 being the default disk type.
General purpose disks (gp3)
$0.000171 per GB-Hr ($0.125 per GB per month). The primary database of your project gets provisioned with an 8 GB disk. You are only charged for provisioned disk size exceeding these 8 GB.
| Plan | Included Disk Size | Over-Usage per GB per month | Over-Usage per GB-Hr |
|---|---|---|---|
| Pro | 8 GB | $0.125 | $0.000171 |
| Team | 8 GB | $0.125 | $0.000171 |
| Enterprise | Custom | Custom | Custom |
Launching a Read Replica creates an additional database with its own dedicated disk. You are charged from the first byte of provisioned disk for the Read Replica. Refer to Manage Read Replica usage for details on billing.
High performance disks (io2)
$0.000267 per GB-Hr ($0.195 per GB per month). Unlike general purpose disks, high performance disks are billed from the first byte of provisioned disk.
| Plan | Included Disk size | Usage per GB per month | Usage per GB-Hr |
|---|---|---|---|
| Pro | 0 GB | $0.195 | $0.000267 |
| Team | 0 GB | $0.195 | $0.000267 |
| Enterprise | Custom | Custom | Custom |
