# Content Delivery Network Billing

## Prerequisites

Content delivery network resources are all [**subscription**](https://docs.console.zenlayer.com/welcome/pricing/general-pricing-rules/subscription) resources. Please first see [**General Pricing Rules**](https://docs.console.zenlayer.com/welcome/pricing/general-pricing-rules) and [**General Lifecycle Rules**](https://docs.console.zenlayer.com/welcome/pricing/general-lifecycle-rules) to know about basic pricing ways of subscription resources.

{% hint style="info" %} <mark style="color:blue;">**Note**</mark>

* <mark style="color:blue;">Any usage exceeding the data transfer package deduction will be charged on a pay-as-you-go basis, resulting in a postpaid bill. Please purchase an appropriate package based on your required services.</mark>
* <mark style="color:blue;">Your bills are usually generated within 24 hours after the end of the current subscription term, subject to the actual billing time of the system.</mark>
  {% endhint %}

## Data Transfer Package

Data transfer package billing does not distinguish between areas. The specifications and corresponding prices are shown in the table below.

<table><thead><tr><th width="325">Data transfer package</th><th>Price/Month</th></tr></thead><tbody><tr><td>1 TB</td><td>$25</td></tr><tr><td>10 TB</td><td>$250</td></tr><tr><td>50 TB</td><td>$1250</td></tr><tr><td>100 TB</td><td>$2500</td></tr><tr><td>> 100 TB</td><td>Please contact us.</td></tr></tbody></table>

{% hint style="info" %} <mark style="color:blue;">**Note**</mark>

<mark style="color:blue;">1 TB = 1000 GB</mark>

<mark style="color:blue;">Price of 1 TB data transfer package: 1000 GB × $0.025/GB = $25.</mark>
{% endhint %}

## **Data Transfer Overages**

The charges for data transfer exceeding the package are calculated based on the area. The excess data usage is billed according to the price per unit of data transfer in that specific area. The pricing details for different areas are shown in the table below.

<table><thead><tr><th width="558">Area</th><th>Price/GB</th></tr></thead><tbody><tr><td>North America-NA European Union-NAEU (EU: Germany, France, UK, Spain)</td><td>$0.025</td></tr><tr><td>Asia Pacific 1-AP1 (Hong Kong, Singapore, Japan, Malaysia, Vietnam, Thailand, Cambodia, Myanmar, Bangladesh, Philippine, Pakistan)</td><td>$0.048</td></tr><tr><td>Asia Pacific 1-AP2 (Indonesia,India, Korea, Taiwan)</td><td>$0.072</td></tr><tr><td>Asia Pacific 1-AP3 (Australia)</td><td>$0.064</td></tr><tr><td>Middle East &#x26; Africa-MEAA (South Africa, Nigeria, Arabia, Dubai, Qatar)</td><td>$0.06</td></tr><tr><td>South America-SA (Brazil, Colombia, Chile, Argentina)</td><td>$0.06</td></tr><tr><td>Other</td><td>$0.025</td></tr></tbody></table>
