Manage Disk size usage

* * *

## What you are charged for[#](#what-you-are-charged-for)

Each database has a dedicated [disk](../../compute-and-disk/index.md#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](../../database-size/index.md).

## How charges are calculated[#](#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-on-your-invoice)

Usage is shown as "Disk Size GB-Hrs" on your invoice.

## Pricing[#](#pricing)

Pricing depends on the [disk type](../../compute-and-disk/index.md#disk-types), with gp3 being the default disk type.

### General purpose disks (gp3)[#](#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.

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](../read-replicas/index.md) for details on billing.

### High performance disks (io2)[#](#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.

To see how your disk usage is distributed across Database, WAL, and System categories, refer to [Disk size distribution](../../database-size/index.md#disk-size-distribution).

## Reduce Disk size[#](#reduce-disk-size)

To see how you can downsize your disk, refer to [Reducing disk size](../../database-size/index.md#reducing-disk-size)

## Exceeding Quotas[#](#exceeding-quotas)

If you are on a paid plan and have [Spend Cap](../../cost-control/index.md#spend-cap) disabled or your organization is on Team Plan or above, you will pay for any overages.
