Fee-rate curve by confirmation target

The site retains last-good public observations. As more samples accumulate, this page can compare the current curve with earlier network conditions.

Fees buy block space, not bitcoin value

A transaction moving 0.01 BTC can cost more than one moving 10 BTC if it has more inputs or bids a higher sat/vB rate. Miners generally compare fee rate because blocks have limited weight.

Historical averages can hide spikes

Demand can change within minutes. A daily median may hide a short rush, while a peak may describe only a few blocks. Always pair the time range with the statistic.

Estimate your own transaction in the UTXO planner or inspect the live backlog in the mempool explorer.

Why fee estimates disagree

  • Nodes can observe different mempools.
  • Models use different recent blocks and probability targets.
  • Wallets choose different safety margins.
  • Child-pays-for-parent packages change effective fee rates.
  • Replace-by-fee can raise a transaction’s bid later.

No target is a promise

Miners choose transactions independently. A quoted target should be read as an estimate under current conditions, not a guaranteed service level.

How Bitcoin.now handles tool data

Calculated values

Deterministic tools state their assumptions beside the result. They do not present a model as an executable quote.

Observed values

External observations use read-only public data, retain the latest valid cache, and show freshness when a source is delayed.

Safety boundary

No tool trades, broadcasts, connects a wallet, stores a secret, or gives personal financial advice.

Review the data methodology, editorial policy, and risk disclaimer.

Using bitcoin historical fee explorer responsibly

What is sat/vB?

Satoshis per virtual byte is the transaction's fee rate. It lets miners compare the reward offered for the block space consumed rather than the bitcoin value transferred.

Can a low-fee transaction be accelerated?

Some transactions can use replace-by-fee or a child-pays-for-parent package. Availability depends on transaction structure, wallet support and node policy.

Why retain cached observations?

A history is built from labelled point-in-time samples. Keeping the last valid sample also prevents a temporary upstream outage from turning the entire page blank.

See what the fee market has actually charged

The explorer plots fee rates over time so a reader can tell an ordinary week from an exceptional one. Fees are a market for block space, and their history is the best guide to what counts as expensive.

Median tells a truer story than average

A handful of very high-fee transactions pull the average up while most users paid far less. The median is the rate a typical confirmed transaction paid, which is what a sender needs to know.

  • Read the median for planning, the average for what miners earned.
  • Check whether the series is per day or per block.
  • Rates are in sat/vB; multiply by size for a cost.

Spikes have causes you can name

Late 2017 saw exchange-driven congestion; spring 2021 followed a price surge; May 2023 and April 2024 were driven by inscriptions and token protocols competing for block space. Each spike fell back within weeks.

  • Compare a spike with the price chart before assuming a link.
  • Watch the mempool backlog that preceded each rise.
  • Note that SegWit and batching lowered the size of typical payments.
