# Data transfer estimator

Estimate bandwidth and egress cost for sending telemetry out of your network.

## How it works

Telemetry is compressed before it’s sent, so the bytes on the wire are a fraction of the raw volume.

```
sent = raw ÷ compression
```

## Questions

### Is egress always charged?

Most clouds charge for data leaving their network; traffic inside a region is often cheaper or free.

### How do I lower it?

Enable gzip, sample traces and drop noisy logs before they leave.
