Bitcoin security budget · fees

What share of Bitcoin miner revenue comes from fees?

Over the trailing 30 days, fees are 0.64% of what Bitcoin’s miners are paid (as of 2026-09-07) — about $1.8K per block on a trailing-year basis. The all-time peak day was 2024-04-20 at 75.2%; the best 30-day window was January 2018 at 26.2%.

Fee share of miner revenue, from daily fee and revenue series. The average is over the whole epoch; the peak is a single day. A day is not a budget.

Sustained, not spiked

The longest stretch above 20% is 40 days, ending 2018-01-31. Bitcoin has never held 30% for a 30-day window. To close today’s gap to a 1% target on fees alone would take about 18% held permanently — see when the subsidy ends.

A note on bases

“Fee share” is quoted here as fees over total miner revenue (subsidy plus fees). Some sources quote fees over the subsidy alone, which reads higher: on 2024-04-20 the same day was 304% on that basis. Both are correct; they are different denominators.
