# Estimate staking fees

> This operation calculates the fee required for a staking activity based on factors such as network congestion and transaction complexity.

For some protocols, you can use the `fee.fee_rate` property in the request body to specify the fee rate you are willing to pay.

The `fee.max_fee_amount` property in the request body will be ignored.

<Note>For the Babylon protocol, you can only select UTXO as the fee model.</Note>
