# Add Fee Modifiers

Fee modifiers offer the ability to set an entity of your choice as liable for paying a specific fee and whether the final fee amount paid by the chosen entity is marked up.

The following sections describe the ways you can add fee modifiers.

## Add Modifiers to a New Fee

To add fee modifiers as you’re setting up a fee:

1. Click **Advanced Options** in the Add Fee dialog after your [initial fee setup](/v1/docs/set-up-a-fee#set-up-a-group-or-merchant-fee).
2. Select **Deduct this fee from another entity**.
3. Under the **Deduct fee from** dropdown menu, select the entity that will pay the fee charge.
4. Click **Add** to apply the fee modifier to your new fee.

## Add Modifiers to an Existing Fee

To add fee modifiers to an existing fee:

1. Access the Fees Details page for the fee:
  1. Select **Groups** or **Merchants** under Management in the main side bar.
  2. Select the Group or merchant that you want to charge the fee to.
  3. Select **Fees** from the page side bar, and then select the****fee that you want to modify.
2. Click the **Add Fee Modifiers** in the upper-right corner of the Fee Modifiers section.
3. Set the unit of measurement, amount, group (if applicable), and the ID of the entity that will pay the fee. The following table describes each field:

| Fee Modifier Field | Description |
| --- | --- |
| Type | Type of fee modification: *Actual* (dollar amount) or *Percentage* (of fee totals) |
| Amount | The actual or percentage amount in basis points |
| Group | The group ID |
| From Entity ID | The entity ID for the entity that will be charged the modified fee |
