BTC: Captured Mempool Base Fees by Fee Rate — Nine USD Bands
Bitcoin Captured Mempool Base Fees by Fee Rate — Nine USD Bands: daily data through 5 Nov 2026.
The dollar value of the fees offered by unconfirmed Bitcoin transactions in our node's mempool, its queue of transactions waiting for a block, stacked by fee rate in nine bands from under 1 sat/vB to 50 sat/vB or more.
Why use it. It shows where the fee money in the queue sits: much of it in the top bands means a congested network and rising fees; most of it in the bottom bands means a quiet one. How to read it. The bands are 0-1, 1-2, 2-3, 3-4, 4-5, 5-7, 7-10, 10-50 and 50+ sat/vB. Each point is the last reading of the queue in the 10 minutes, hour or day, not an average. It is one node's view of the queue, not the whole network's, and not a forecast of confirmation times.
Calculation. Exact definition: Captured local Bitcoin Core mempool base fees in USD, stacked across nine fee-rate bands from 0 to under 1 sat/vB up to 50+ sat/vB. The nine lower-inclusive, upper-exclusive bands are 0–1, 1–2, 2–3, 3–4, 4–5, 5–7, 7–10, 10–50 and 50+ sat/vB, covering one complete captured population; dollars help compare captured monetary load. Each UTC 10-minute, hour or day point uses its last actual capture. Missing or unpriced captures remain gaps, while a proved empty capture with an eligible quote is zero; read sampling and priced-capture coverage alongside. This is one local node's prospective snapshot, not a global mempool, execution price or confirmation-time forecast. Group each captured transaction by its Core base fee divided by Core policy virtual size, sum the exact base-fee satoshis per band, and multiply each sum by the same originally admitted prospective BTC/USD quote divided by 100,000,000, keeping reduced rational values until decimal rounding. Base fees exclude prioritization deltas and package averaging. The original capture and received quote are reused, never a later quote, and monetary freshness uses the earlier of their clocks. History starts at 2026-10-05; earlier mempool history and historical-known-then prices are unavailable.
