# Total cart weight discount

# Total cart weight discount

Use Total cart weight discount to lift AOV from heavy or bulk shoppers by rewarding them with a discount, free gift, or free shipping once their total cart weight hits a threshold.

## How it works

Total cart weight discount runs inside the **Order Discount** campaign type. Pareto adds up the weight of every product in the cart and unlocks a discount when the total passes the threshold you set. Use it to offer free shipping, a free gift, or money off once the cart gets heavy enough.

Example: Free shipping on orders over 10Kg, $30 off over 20Kg, 12% off over 50Kg.

## Before you begin

* You're on the **Professional** plan or **Advanced** plan.
* Each product variant has a **weight** value set in Shopify. Variants with no weight are counted as `0 Kg`.
* Weight unit is **Kg**. Other units are converted automatically.

## Create a Total cart weight discount

1. Go to **Pareto** > **Campaigns** > **Create offer**.
2. Choose **Order Discount** as the campaign type.
3. Select the **Total cart weight discount** template.
4. Click **Save**.

## Configure your rules

In the **Discount rules** section, add one rule per tier. Each rule defines a weight range and the discount that applies inside it.

| Setting | Description |
| ---- |
| Buy from (weight) | Minimum cart weight in Kg for this tier to apply. |
| Buy to (weight) | Maximum cart weight in Kg for this tier. Leave empty for an open-ended top tier. |
| Value | Discount value and type. See **Discount types** below. |
| Discount for quantities in multiples of buy from | When checked, the discount repeats every time the buy-from weight is reached. Enabling this removes all other rules and keeps only this rule. |

To add another rule, click **+ Add**. To remove a rule, open it and click **Remove**.

## Discount types

Total cart weight discount supports five discount types:

| Type | Behavior |
| ---- |
| `%` | Percentage off the cart subtotal once the weight tier is hit. |
| `Amount per Kg` | Multiplies the value by the actual cart weight. See example below. |
| `Price` | Fixed amount off the cart total. |
| `Free gift` | Adds a selected product to the cart at $0. |
| `Free shipping` | Removes shipping cost at checkout. |

### How "Amount per Kg" is calculated

`Amount per Kg` is not a flat discount. Pareto multiplies the value you set by the customer's actual cart weight.

Example: Tier set to `$5 off per Kg`.
* Cart weight 1.5Kg, discount = `$5 × 1.5 = $7.50`
* Cart weight 3Kg, discount = `$5 × 3 = $15.00`
* Cart weight 10.25Kg, discount = `$5 × 10.25 = $51.25`

Use this when shipping or fulfillment cost scales with weight and you want the discount to scale with it too.

## Exclusions

Use **Exclude specific products** when some items shouldn't help unlock the discount.

* **Exclude from condition only**, products won't count toward the weight trigger but still receive the discount.
* Excluded products are searched by name or added via **Browse**.

## Limitations

* Available on the **Professional** and **Advanced** plans only.
* Weight is read from Shopify product variant settings. Variants with no weight count as `0 Kg`.
* Only Kg is shown in the UI. Other units are converted automatically.
