UTXO Consolidation Calculator

Keep more ₿ by tidying up your wallet at the right time

Every separate chunk of bitcoin in your wallet costs its own fee to spend. Dozens of small chunks quietly eat into your stack when you finally move it.
Combine them into one lump sum while fees are cheap and you pay pennies once, instead of dollars over and over later.

Network fees regularly swing by 10x or more. The calculator below checks whether now is your window.

Your wallet

Number of UTXOs UTXO: An unspent chunk of bitcoin in your wallet. Like coins in a piggy bank: you spend all of one at a time.

Average UTXO size (sats) Sats: The smallest unit of bitcoin. 100,000,000 sats = 1 BTC. Most wallets can show your balance in sats.

UTXO amounts, one per line Copy the amounts column from your wallet’s UTXO list (Sparrow: UTXOs tab · Electrum: Coins tab). Whole numbers are read as sats; numbers with a decimal point (like 0.00250000) are read as BTC and converted.

Current fee rate (sat/vB), filled in for you sat/vB: We look this number up for you automatically from mempool.space, the standard Bitcoin network monitor. It measures how busy the network is right now. Higher means more expensive to send. Edit it only if you want to test a different scenario.
