# estimatedProgress

An estimate of completion percentage of the current navigation.

```
@MainActor final var estimatedProgress: Double { get }
```

## Discussion

The value ranges from `0.0` to `1.0` based on the total number of bytes received, including the main
document and all of its potential subresources. After navigation loading completes, the `estimatedProgress`
value remains at `1.0` until a new navigation starts, at which point the `estimatedProgress` value resets
to `0.0`.
