# Volume Weight Calculator

This article explains volumetric weight, how it affects shipping costs, and how to activate and use the calculator.

## What is volume weight?

Volume weight is a calculated weight based on how much space a package occupies.

Shipping costs are always calculated using the highest value of:

-   actual weight (kg)
-   volume weight (kg)

Large but lightweight products often have a higher volume weight than their actual weight.

## How to activate the volume weight calculator

1.  Go to **Extensions** → **Your extensions**
2.  Search for **Volume weight**
3.  Click **+Install extension**

## How to use the volume weight calculator

1.  Go to **Products** → **Products**
2.  Find the relevant product
3.  Click **Edit**
4.  In the **Miscellaneous** tab, click **Volume weight**
5.  Enter the package:
6.  -   length (cm)
    -   width (cm)
    -   height (cm)
7.  Read the calculated volume weight (kg)
8.  Click **Add volume weight** if the volume weight is higher than the actual weight

*Always use the measurements of the packaging that will actually be shipped.*

## How volume weight is calculated

Volume weight is calculated as:

**(L × W × H) / Volumetric factor**

-   Measurements must be entered in centimeters (cm)
-   The volumetric factor is defined by the carrier
-   The volumetric factor may vary depending on transport type

### Example

-   Dimensions: 50 × 40 × 30 cm
-   Actual weight: 2 kg
-   Volumetric factor: 5000

**Calculation:**  
(50 × 40 × 30) / 5000 = 12 kg

Shipping will be calculated based on 12 kg because the volume weight is higher than the actual weight.

## Important to know

-   The highest weight is always used in the shipping calculation.
-   Incorrect weight may result in incorrect shipping costs.
-   The volumetric factor is determined by the carrier.
-   Large and lightweight products often have high volume weight.

## Troubleshooting

**Problem:** Shipping cost is higher than expected  
**Cause:** The product has a high volume weight  
**Solution:** Verify the packaging dimensions and recalculate the volume weight

### What if this does not solve the issue?

1.  Go to **Configuration** → **General** → **Shipping / Packing**
2.  Check the field **Weight per parcel**
3.  Adjust the limit if the order is split into multiple parcels

If the issue persists, contact customer support and include:

-   product name or SKU
-   packaging dimensions (L × W × H)
-   actual product weight
-   carrier/shipping method
-   order number (if related to a specific order)
