BTC: Captured Mempool Base Fees at 10–<50 sat/vB in USD

Bitcoin Captured Mempool Base Fees at 10–<50 sat/vB in USD was $123.46 on 5 Nov 2026 (latest daily value).

The dollar value of the fees offered by unconfirmed Bitcoin transactions paying 10 to 50 sat/vB, in our node's mempool, its queue of transactions waiting for a block.

Why use it. It shows how much fee money is waiting at higher fee rates paid by users in a hurry. How to read it. Each point is the last reading of the queue in the 10 minutes, hour or day, not an average. Higher means more fee money waiting at this rate; a build-up in the upper bands means users are paying up to get in. 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 base fees from transactions paying 10 to under 50 sat/vB in the captured local Bitcoin Core mempool. Each UTC 10-minute, hour or day point uses its last actual capture, not an average. Band membership stays in sat/vB, lower-inclusive and upper-exclusive; dollars help compare captured monetary load. Missing or unpriced captures remain gaps, including a zero native total without a quote, 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 in this band, and multiply by the 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.
