# Billing for Storage

Krutrim Cloud provides flexible, usage-based pricing for all storage services including **Block Storage**, **Snapshots**, **Backups**, and **Object Storage**. This guide outlines the pricing models, metering logic, and example calculations to help you understand and manage your storage costs effectively.

***

### Billing Overview

Storage usage is metered **hourly**, and prices are displayed on a **per GB per month** basis for ease of comparison. However, final billing is calculated on an **hourly peak usage** basis, which ensures you're charged accurately and proportionately.

You are only billed for **active storage** — i.e. attached block volumes, retained snapshots or backups, and stored objects.

***

### Block Storage

Block Storage volumes are persistent disks that can be attached to VMs or AI Pods. You can provision volumes ranging from **4 GB to 2048 GB**.

#### Pricing

* **Monthly Rate**: ₹7.88 per GB
* **Hourly Rate**: ₹0.011 per GB
* **Size Range**: 4 GB to 2048 GB

{% hint style="info" %}
*Need more than 2048 GB?*

Contact our sales team at <cloudsupport@olakrutrim.com> for custom provisioning.
{% endhint %}

***

### Metering Logic

All storage services follow a **peak usage metering model**, where:

* Usage is calculated based on **maximum provisioned or consumed capacity** in any given hour.
* The total monthly bill is the **sum of hourly peak usage**, multiplied by the hourly rate.

#### Example

{% tabs %}
{% tab title="Case 1" %}
**Single Volume, Consistent Size**

* Volume: 1 volume of 100 GB
* Duration: 10 continuous hours
* **Billing Calculation**: `100 GB × ₹0.011 × 10 hours = ₹11`
  {% endtab %}

{% tab title="Case 2" %}
**Multiple Volumes, Consistent Size**

* Volume 1: 50 GB for 10 hours
* Volume 2: 40 GB for 10 hours
* **Peak Hourly Usage**: 50 + 40 = 90 GB for each hour
* **Billing Calculation:** 90 GB × ₹0.011 × 10 hours = **₹9.90**
  {% endtab %}

{% tab title="Case 3" %}
**Dynamic Usage Across Volumes**

* Volume 1:
  * 50 GB for first 5 hours
  * 40 GB for next 5 hours
* Volume 2: 20 GB for entire 10 hours

| Time Period | Volume 1 (GB) | Volume 2 (GB) | Total Peak (GB) |
| ----------- | ------------- | ------------- | --------------- |
| Hours 1–5   | 50            | 20            | 70              |
| Hours 6–10  | 40            | 20            | 60              |

* **Billing Calculation**:\
  `(70 GB × ₹0.0068 × 5 hours) + (60 GB × ₹0.0068 × 5 hours)`\
  `= ₹2.38 + ₹2.04 = ₹4.42`
  {% endtab %}
  {% endtabs %}

***

### Snapshots

Snapshots are point-in-time backups of your block volumes. You can use them to restore or clone volumes.

***

### Backups

Backups are long-term, durable storage copies of your volumes and can be stored independently of the source.

{% hint style="info" %}
Backups are billed separately from volumes and snapshots, even if they contain the same data.
{% endhint %}

***

### Object Storage

Krutrim Cloud Object Storage offers scalable, highly available storage for unstructured data such as backups, images, videos, and application data.&#x20;

### **Pricing Structure**

| Storage Type / Tier | Flavor         | Unit | Price / GB / Hour | Price / GB / Month |
| ------------------- | -------------- | ---- | ----------------- | ------------------ |
| Tier 1              | 0 – 5 GB       | Hour | ₹0                | ₹0                 |
| Tier 2              | 5 GB – 50 TB   | Hour | ₹0.0023           | ₹1.66              |
| Tier 3              | 50 TB – 500 TB | Hour | ₹0.0022           | ₹1.61              |
| Tier 4              | Above 500 TB   | Hour | ₹0.0021           | ₹1.54              |

***

### **Billing Details**

* **Metering**: Usage is metered hourly by using the peak storage of that hour.
* **Free Tier**: First **5 GB** of storage per month is free.
* **Tiered Billing**: Pricing is applied per tier based on total monthly usage. For example:
  * If you store **60 TB** in a month:
    * First 5 GB → Free
    * Next 49.995 TB → ₹1.66/GB
    * Remaining 10 TB → ₹1.61/GB
* **Pro-Rata Charges**: If storage is created or deleted during the month, charges apply only for the hours used.
* **Minimum Billing Interval**: 1 hour.

***

### **Example Cost Calculation**

**Scenario**:\
A customer stores **120 TB** of data for a full month.

**Calculation**:

* Tier 1: First 5 GB → ₹0.00
* Tier 2: Next 49.995 TB → 49,995 GB × ₹1.66 = ₹82,992.70
* Tier 3: Next 70 TB → 70,000 GB × ₹1.61 = ₹112,700.00\
  **Total = ₹195,692.70 for the month**

***

### Additional Billing Considerations

* **Detached Volumes**: You will still be charged for storage even if a volume is detached from a VM.
* **Retained Snapshots or Backups**: These incur ongoing costs as long as they are stored in your account.
* **Data Transfer Costs**: Intra-region data movement is free, but egress or inter-region transfers may incur charges (coming soon).
