# Budget distribution

> Split one budget across the ad units below it by a model, and see every split in one place.

> [!NOTE]
>
> **Find it in** Automations, Distributions tab. **Last updated** 9 Oct 2026.

## Overview

A budget distribution takes a budget set at one level and splits it across the ad units one level down, for example a campaign budget across its ad objects. A model decides the split, using a benchmark metric. The **Distributions** tab lists every split in the workspace so you can see what is running and on which account.

## How it works

**1. A budget sits at the top**

The split starts from a budget on a campaign, ad object or ad account.

**2. A model splits it**

The model divides that budget across the ad units below, weighted by a **Benchmark metric**: **Ads GMV**, **Ads spend**, **ROAS** or **Impression**.

**3. It runs in its window**

**Active window** and **Valid dates** set when the split applies.

## Use it

### See your distributions

Open **Automations** and select the **Distributions** tab. Each row reads what it splits, the model and the schedule. Select **Show budget dashboard** for the totals above the list.

### Read one distribution

Select a row to open its detail: **Model**, **Benchmark metric**, **Benchmark date**, **Active window** and **Valid dates**. The units listed come from the current live split.

### Change a distribution

Distribution settings live on the campaign. In the detail, select **Open campaign configuration** to change the model or the benchmark.

### Start a new one

Open the menu next to **New script** and select **New distribution**. Pick a template from the **Budget distribution** gallery, then finish the setup on the campaign.
