# Set and manage index rates

Legacy experience
This page describes how to reach index rate tools when you use the **legacy** Admin Portal layout (top navigation bar and header **Admin options**). If you use the updated sidebar layout, see [Set and manage index rates](/servicing-operations/admin-portal/admin-portal-index-rates).

Index rates are benchmark interest rates (such as the prime rate or Federal Funds rate) used to calculate variable APRs on loans. If your loan types use variable interest rates, the index rate tools let you define and update these rates over time.

**Availability:** All clients on the legacy Admin Portal layout (accessed from the header, not the sidebar)
**Required permissions:** `indexrates:list`, `indexrates:read`, and `indexrates:update` are all needed for the **Manage index rates** entry to appear in the **Admin options** dropdown. `indexrates:create` is required to add a rate, and `indexrates:delete` is required to remove one.

## Navigate to index rate tools

Index rate tools are not in the sidebar. To access them:

1. Select **Admin options** in the top-right area of the Admin Portal header.
2. Select **Manage index rates**. The Manage page is the entry point for both viewing existing rates and adding a new one.


## Add a new index rate

1. From **Admin options**, select **Manage index rates**.
2. On the **Manage index rates** page, select **+ Add index rate**. The **Add index rate** page opens.
3. Fill in the index rate details (see [field reference](#index-rate-fields) below).
4. Select **Add** to save.


## Manage existing index rates

1. From **Admin options**, select **Manage index rates**.
2. Select a loan type from the **Applicable to** dropdown to load its index rates.
3. The rates list shows all index rates defined for that loan type, each displaying its date range and percentage. Select the rate you want to modify.
4. Update the fields you want to change.
5. Select **Update index rate** to save, or **Cancel** to discard.


To add another rate, select **+ Add index rate** from this page.

### Remove an index rate

1. From the **Manage index rates** page, select the loan type and the rate you want to remove.
2. Select the delete icon next to the rate.
3. The remaining rates' date ranges adjust automatically after removal.
