Manage Disk Throughput usage

* * *

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

Each database has a dedicated disk, and you are charged for its provisioned disk throughput. However, unless you explicitly opt in for additional throughput, no charges apply.

Refer to our [disk guide](../../compute-and-disk/index.md#disk) for details on how disk throughput, disk IOPS, disk size, disk type and compute size interact, along with their limitations and constraints.

Disk Throughput is **not** covered by the [Spend Cap](../../cost-control/index.md#spend-cap).

Launching a Read Replica creates an additional database with its own dedicated disk. Read Replicas inherit the primary database's disk throughput settings. You are charged for the provisioned throughput of the Read Replica.

## How charges are calculated[#](#how-charges-are-calculated)

Disk throughput is charged by MB/s-Hrs (MB/s stands for megabytes per second). 1 MB/s-Hr represents disk throughput of 1 MB/s being provisioned for 1 hour. For example, having 10 MB/s provisioned for 5 hours results in 50 MB/s-Hrs (10 MB/s × 5 hours).

### Usage on your invoice[#](#usage-on-your-invoice)

Usage is shown as "Disk Throughput MB/s-Hrs" on your invoice.

## Pricing[#](#pricing)

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

### General purpose disks (gp3)[#](#general-purpose-disks-gp3)

$0.00013 per MB/s-Hr ($0.095 per MB/s per month). gp3 disks come with a baseline throughput of 125 MB/s. You are only charged for provisioned throughput exceeding these 125 MB/s.
