Definition
Hash price (also written hashprice) is the expected mining revenue earned per unit of hashrate over a day, normally quoted in USD per terahash per second per day (USD/TH/day) or in the denominated form of satoshis per terahash per day. It collapses three moving variables, the Bitcoin price, the network difficulty, and transaction fees, into a single number that tells you what a terahash of work is worth right now.
Why hash price is the miner’s reference number
Every ASIC produces hashrate, but hashrate alone says nothing about money. Hash price is the bridge between the physics on your bench and the economics in your wallet. Multiply your machine’s hashrate by the current hash price and you get an estimate of gross daily revenue before electricity. A 200 TH/s miner running at a hash price of, for example, $50/PH/day (the metric is often quoted per petahash for convenience) earns roughly 200 TH/s times that rate in expected revenue. Because the figure is revenue, not profit, you still have to subtract your power cost and pool fee to know whether the machine should stay powered on.
The number changes constantly. It is driven up when the Bitcoin price rises or when mempool congestion pushes transaction fees higher, and it is driven down when difficulty climbs because more hashrate has joined the network and the fixed block reward is split among more participants. Difficulty retargets roughly every two weeks (every 2,016 blocks), so a quiet fortnight on price can still erode hash price as competitors plug in machines.
What feeds into the number
- Block subsidy. The largest input is the coinbase subsidy paid to the winning miner. Each halving cuts that subsidy in half, which is why hash price tends to step down sharply after a halving event unless price or fees rise to compensate.
- Network difficulty. As total hashrate grows, difficulty rises and each terahash claims a smaller slice of the daily issuance. This is the single biggest reason hash price grinds lower over long horizons.
- Transaction fees. Fee revenue is volatile. During high-demand periods, ordinal inscriptions, or fee spikes, fees can add a meaningful premium on top of the subsidy, briefly lifting hash price.
- Bitcoin price. Since the metric is usually quoted in fiat, the spot BTC/USD rate scales the whole figure. Quoting hash price in sats per terahash strips this out and isolates the protocol-level economics.
How hash price shapes real hardware decisions
For anyone running ASICs, hash price is the daily input to almost every operational choice. Pools that pay on a Full Pay Per Share basis (see FPPS) effectively pay you the expected value derived from hash price, including the fee component, regardless of whether your shares landed a block. That predictability is one reason FPPS remains popular among hosted and home miners alike.
Hash price also sets your shutdown line. Every miner has a break-even hash price below which the electricity to run the machine costs more than the coins it earns. A modern unit at roughly 15-21 J/TH break-evens at a far lower hash price than an older S9-era machine near 90-100 J/TH, which is why efficiency, not raw hashrate, decides who survives a downturn. When hash price drops, efficient fleets keep running while inefficient hardware is the first to be unplugged.
This is where firmware tuning earns its keep. In a low-hash-price environment, underclocking an ASIC to a lower frequency and voltage sacrifices some hashrate but improves J/TH, lowering the break-even point and keeping the machine profitable longer. When hash price recovers, the same machine can be pushed back toward higher output. Custom firmware that exposes power profiles and watt-anchored targeting turns hash price from a number you watch into a lever you can pull. This is precisely the kind of on-device economic awareness that the open-source DCENT_OS project (currently in closed beta, GPL-3.0, with public beta planned for summer 2026) is being built to support, letting an operator set a break-even threshold and have the firmware respond rather than depending on a cloud dashboard.
Hash price feeds directly into mining profitability calculations and, alongside electricity rates, defines your hash cost, the flip side of the same coin: hash price is what a terahash earns, hash cost is what it costs you to produce. The gap between the two is your margin.
Reading hash price in context
Treat any single hash-price quote as a snapshot, not a forecast. It reflects current price, current difficulty, and current fees, all of which move. Long-term, the trend is downward as the network grows and subsidies halve, so sustainable mining depends on cheap power, efficient hardware, and the discipline to tune for the conditions you actually have rather than the ones you wish you had.
If you are evaluating whether your fleet earns at today’s hash price, the place to start is hardware efficiency. Browse the efficiency specs across our miner database to compare J/TH ratings and find the break-even point that fits your power cost.
In Simple Terms
Revenue per terahash per day. A key metric showing the economic value of mining power at any given time.
