BTC: Captured Mempool Output Value by Fee Rate — Nine USD Bands

Bitcoin Captured Mempool Output Value by Fee Rate — Nine USD Bands: daily data through 5 Nov 2026.

The dollar value of everything unconfirmed Bitcoin transactions are sending, 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 how the money waiting to move is spread across fee rates, from patient to urgent. 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. The value counts every output, including change and chains of transfers, so it is not the amount actually paid between people. It is one node's view of the queue, not the whole network's, and not a forecast of confirmation times.

Calculation. Exact definition: The USD value of all decoded outputs of captured local Bitcoin Core mempool transactions, 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. Output value counts every decoded output, including change, unspendable outputs and repeated transfers within transaction chains; it is not unique supply, economic payment volume or miner income. 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. 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 output 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. A value needs the original complete membership and an independently decoded population. 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.
