How It Works
Get accurate Bitcoin transaction fee estimates in four simple steps
Enter Transaction Details
Specify your address type (Legacy, SegWit, Taproot), the number of inputs (UTXOs) and outputs for your transaction.
Fetch Live Network Data
We pull real-time fee recommendations from mempool.space, giving you accurate data on current network conditions.
Calculate Optimal Fee
Based on your transaction size and chosen priority, we calculate the exact fee in satoshis and USD value.
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.
