Bitcoin Transaction Fee Estimator

Inputs, outputs and address type → vBytes, sat/vB and total fee

What is the Bitcoin Transaction Fee Estimator?

The Bitcoin Fee Estimator calculates transaction virtual size and total cost from address type, input/output counts and sat/vB. Live rates prefer estimates from a self-operated Bitcoin Core node.

How do I use the Bitcoin Transaction Fee Estimator?

Accurate UTXO input count matters more than transfer amount. Many small deposits create more inputs and higher fees; compare fast, standard and economy targets.

What should I watch out for?

Transaction size is an estimate for common scripts; multisig, CoinJoin and custom scripts differ. Future block demand is unknowable, so confirmation time is never guaranteed.
