    How It Works

    Get accurate Bitcoin transaction fee estimates in four simple steps

    1

    Enter Transaction Details

    Specify your address type (Legacy, SegWit, Taproot), the number of inputs (UTXOs) and outputs for your transaction.

    2

    Fetch Live Network Data

    We pull real-time fee recommendations from mempool.space, giving you accurate data on current network conditions.

    3

    Calculate Optimal Fee

    Based on your transaction size and chosen priority, we calculate the exact fee in satoshis and USD value.

    4

    Choose Your Priority

    Balance cost vs speed—pay more for faster confirmation or save by choosing economy for non-urgent transactions.

    Pro tip: Using Native SegWit (bc1q) or Taproot (bc1p) addresses can reduce your transaction fees by up to 40% compared to Legacy addresses.
