Manage Disk IOPS 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 IOPS. However, unless you explicitly opt in for additional IOPS, no charges apply.

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

Disk IOPS Hours are **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 IOPS settings. You are charged for the provisioned IOPS of the Read Replica. Refer to [Manage Read Replica usage](../read-replicas/index.md) for details on billing.

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

Disk IOPS is charged by IOPS-Hrs. 1 IOPS-Hr represents 1 IOPS being provisioned for 1 hour. For example, having 10 IOPS provisioned for 5 hours results in 50 IOPS-Hrs (10 IOPS × 5 hours).

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

Usage is shown as "Disk IOPS-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)

$0.00003288 per IOPS-Hr ($0.024 per IOPS per month). gp3 disks come with a default IOPS of 3,000. You are only charged for provisioned IOPS exceeding these 3,000 IOPS.

### High performance disks (io2)[#](#high-performance-disks-io2)

$0.000163 per IOPS-Hr ($0.119 per IOPS per month). Unlike general purpose disks, high performance disks are billed from the first provisioned IOPS.

## Billing examples[#](#billing-examples)

### Gp3[#](#gp3)

Project 1 doesn't exceed the included IOPS, so no charges for IOPS apply. Project 2 exceeds the included IOPS by 600, incurring charges for this additional usage.
