# Liquidity Position Fee

> Retrieve the current fee for creating or adding to a liquidity position

The following code demonstrates how to retrieve the fee for minting a new liquidity position or adding to an existing position, with the fees expressed in HBAR, using a combination of JSON-RPC and REST API calls.

<Note>
  The **mintFee()** function will return the current fee expressed in **Tinycent** (US).
</Note>

    const tinybar = BigNumber(tinycent / centToHbarRatio).decimalPlaces(0);
    const poolCreateFeeInHbar = Hbar.from(tinybar, HbarUnit.Tinybar);
    console.log(`New liquidity position fee: ${poolCreateFeeInHbar.toString(HbarUnit.Hbar)}`);
