Median and Mean Transaction Fee

Show the typical (median) and average (mean) transaction costs on the network, reflecting user competition for block inclusion.

Overview
While mean fee reflects the overall average, median fee filters out extreme outliers, offering a clearer view of typical user costs. Both metrics can be expressed in BTC or USD, and also per byte — indicating efficiency in transaction size vs. cost.

Formulas

M e d i a n T x F e e = m e d i a n ( T x F e e 1 , T x F e e 2 , . . . , T x F e e n ) MedianTxFee = median(TxFee_1, TxFee_2, ..., TxFee_n)
M e a n T x F e e = ∑ i = 1 n T x F e e i n MeanTxFee = \frac{\sum_{i=1}^{n} TxFee_i}{n}
M e a n T x F e e P e r B y t e = M e a n T x F e e T x S i z e m e a n MeanTxFeePerByte = \frac{MeanTxFee}{TxSize_{mean}}

Interpretation

  • High median fees: Users compete heavily for block space — strong demand.

  • Low median fees: Low demand or efficient mempool usage.

  • Mean > median: Few large transactions dominate the network.

Insights
Fee dynamics directly impact miner revenue and can serve as an early indicator of network congestion before price action reacts.
