# Fee model & configuration

The fee models are set up on Upvest side based on the client's requirements. Upvest supports multiple fee models per client.

The fee model contains the percentage of the AUM (assets under management) fee, which is defined in basis points (bps) per year. This value is later used for fee calculation and fee collection.

Upvest communicates the `fee_model_id` which is used for further fee setup.

**Coming soon** 
An endpoint for the creation of fee models will soon be added to the Investment API.

## Fee configuration

Once the fee models have been defined, you must assign a fee model to each account that is to pay fees.

### Creating a fee configuration

Use the fee model IDs (`fee_model_id`) you receive from us to configure the fee configuration. Send your request as follows:

**POST** [`/fees/configurations`](/api/fees-configurations/create_fee_configuration)

Example request
{
  "fee_model_id": "1df86975-06f4-484d-935e-46b54bab2f6c",
  "account_id": "7524949b-31fd-497e-ad92-f52de45341d1"
}

Example response
{
  "created_at": "2021-07-21T14:10:00.00Z",
  "updated_at": "2021-07-21T14:10:00.00Z",
  "fee_model_id": "1df86975-06f4-484d-935e-46b54bab2f6c",
  "account_id": "7524949b-31fd-497e-ad92-f52de45341d1"
}

### Updating a fee configuration

You can update the fee configuration with:

**PATCH** [`/fees/configurations/{account_id}`](/api/fees-configurations/update_fee_configuration)

Only the last fee configuration per day is used to calculate the fees for that day.

Once the fee models and configurations have been set up, you don't need to do anything else for the fee calculations to start.
