# Weighted Average

This Algorithm calculates the weighted average given the input metrics and weights.

![](https://cdn.document360.io/6759e9c9-3ce3-49df-965a-7231d2d9a10a/Images/Documentation/image(166).png?sv=2026-02-06&spr=https&st=2026-10-16T17%3A31%3A24Z&se=2026-10-16T18%3A31%3A24Z&sr=c&sp=r&sig=ngNR6810pHk%2BI%2FI00HYSLezI4hsPov62yCnY8a0ueRc%3D)

Each input value is multiplied by its respective weight, the products are then summed and divided by the sum of the weights.

Mathematically, it can be represented as:

```plaintext
(M1 x W1 + M2 x W2 + ... + Mn x Wn) / (W1 + W2 + ... + Wn)
```

## Inputs

## Insight Metric Configuration

To use this Algorithm in an [Insight Metric](/docs/insight-metrics), you need to:

1. Go to the *Insight / Insight Metrics* page.
2. Select the *Thing Definitions* tab.
3. Select the Thing Definition where to create the insight metric.
4. Click the Add Metric button.
5. Select the *Weighted Average* algorithm.
6. Configure the required inputs.
