Bitcoin Network Fees

Live Bitcoin transaction fees. Estimated USD costs are based on a standard transaction size of 140 vBytes. Updates automatically every minute.

How it works

Bitcoin transactions wait in a queue called the mempool, and miners pick the ones that pay the most per unit of size. The fee rate is measured in satoshis per virtual byte (sat/vB). When the network is busy, you need a higher fee rate to be included in the next block. When it is quiet, a low fee is enough.

The USD cost shown is an estimate for a typical transaction of about 140 vBytes, using the current BTC price. Your wallet may create a larger or smaller transaction, so the real cost can differ. Fee estimates come from public network sources and can change within minutes.

About this data

Bitcoin fees are paid per virtual byte (sat/vB) and depend on how busy the network is. A higher fee gets your transaction into the next block faster, and a lower fee can wait longer. A typical SegWit transaction is around 140 vB, so multiply the fee rate by the size to estimate the total in satoshis. Data comes from mempool.space, with BlockCypher and Blockstream as backups.

What this page shows

Tracks recommended Bitcoin network transaction fees measured in satoshis per virtual byte (sat/vB).

How to read it

Displays priority fee tiers (high, medium, low) along with estimated USD costs based on standard transaction sizes.

Why traders care

Essential for timing on-chain Bitcoin transfers efficiently without overpaying or getting stuck in network congestion.

Common mistakes

  • Using low-priority fee rates during high network congestion when transaction urgency is high.
  • Forgetting that transaction size in vBytes determines total satoshi cost.

Frequently asked questions

What does sat/vB mean in Bitcoin fees?

Sat/vB stands for satoshis per virtual byte. Bitcoin miners prioritize transactions by fee density (data size in vBytes), not by the dollar value being sent.

How is the USD cost of a Bitcoin transaction calculated?

A standard native SegWit (bc1q) transaction is roughly 140 vBytes. Multiplying the current sat/vB rate by 140 gives the total satoshis required, which is then converted to USD.

How can I fix a stuck low-fee Bitcoin transaction?

If your wallet enabled Replace-By-Fee (RBF), you can broadcast the same transaction with a higher sat/vB rate, or use Child-Pays-For-Parent (CPFP).
