# Are paused Novita sandboxes billed?

> Paused sandboxes stop CPU and RAM billing. You pay only for persistent storage beyond the free 60 GB per account, at USD 0.00009/GB/h.

Paused sandboxes stop CPU and RAM billing. While paused, a sandbox's filesystem and memory are kept in persistent storage, which is free up to 60 GB per account and \$0.00009/GB/h beyond that.

## Details

| | Running | Paused | Killed |
| - | - | - | - |
| CPU and RAM billing | Per second | Stopped | Stopped |
| Storage billing | Free (20 GB ephemeral disk) | Persistent storage: 60 GB free per account, then \$0.00009/GB/h | None |
| State kept | — | Filesystem and memory, including running processes | Deleted |
| Can resume | — | Yes, typically in about a second | No |

To see how many sandboxes currently count toward your concurrency limit, check `usage` from the [quota API](https://docs.novita.ai/guides/sandbox-quota-limit.md#check-current-quota-usage).

## How to

```python Python icon="python" theme={"system"}
from novita_sandbox import Novita

novita = Novita()
sandbox = novita.sandbox.create()

sandbox.pause()                                       # stop CPU and RAM billing
sandbox = novita.sandbox.connect(sandbox.sandbox_id)  # resume with state intact
```

```js JavaScript & TypeScript icon="js" theme={"system"}
import { Novita } from 'novita-sandbox'

const novita = new Novita()
const sandbox = await novita.sandbox.create()

await sandbox.pause()                                     // stop CPU and RAM billing
const resumed = await novita.sandbox.connect(sandbox.sandboxId) // resume with state intact
```
