Bitcoin Mining Breakeven Calculator: Find Your Hashprice Floor

How Bitcoin Mining Breakeven Works

Every Bitcoin mining operation has a breakeven point: the electricity rate, BTC price, or hashprice level at which revenue from block rewards and transaction fees exactly covers operating costs. Below that threshold, the miner generates profit. Above it, each hash burns more in electricity than it earns.

The breakeven calculation depends on four variables: your hardware's hashrate (TH/s), its power draw (watts), your electricity rate ($/kWh), and the current hashprice (daily revenue per unit of hashrate). Since the April 2024 halving cut the block subsidy to 3.125 BTC, these margins have compressed significantly. As of mid-2026, hashprice hovers around $32 per PH/s per day, and 15 to 20 percent of global mining capacity has become unprofitable during periods of network stress.

The Breakeven Formulas

Two breakeven calculations matter for miners: the maximum electricity rate your hardware can sustain, and the minimum BTC price required to cover costs.

Breakeven Electricity Rate

This tells you the highest power price at which your ASIC miner remains profitable:

Breakeven $/kWh = (Daily BTC Mined × BTC Price) / (Power in Watts × 24 / 1000)

Where daily BTC mined equals (Your TH/s ÷ Network TH/s) × 144 blocks × 3.125 BTC × (1 − Pool Fee). With the network running at approximately 1,040 EH/s (1.04 ZH/s) as of September 2026, even high-hashrate machines earn fractions of a satoshi per hash.

Breakeven BTC Price

To find the minimum BTC price needed for your operation:

Breakeven BTC Price = (Power in Watts × 24 / 1000 × $/kWh) / Daily BTC Mined

This is the "shutdown price" for a given machine: the BTC price below which it costs more to run than it earns. Miners with older, less efficient hardware hit this threshold first, which is why each difficulty adjustment and halving cycle triggers a wave of hardware retirements.

Days to ROI

Hardware payback period accounts for the upfront capital cost:

Days to ROI = Hardware Cost / (Daily Revenue − Daily Electricity Cost)

This metric is particularly important in the current post-halving environment where daily margins are thin. A machine earning $5 per day in net profit after electricity takes 600 days to pay back a $3,000 purchase price.

Current ASIC Miner Reference

Efficiency, measured in joules per terahash (J/TH), is the single most important spec for breakeven analysis. Lower J/TH means less electricity consumed per unit of hashrate, which directly lowers your breakeven threshold. The following table covers the current generation of mining hardware from all three major manufacturers.

The efficiency gap between the best and worst machines in this table is 7 J/TH. That difference translates directly into breakeven electricity rates: a 12 J/TH machine can survive power costs roughly 58% higher than a 19 J/TH machine at the same hashprice. For a detailed revenue projection with any of these models, use the Bitcoin mining profitability calculator.

Hashprice: The Metric Miners Track

Hashprice is the expected daily revenue per unit of hashrate, typically expressed as USD per PH/s per day (or equivalently, USD per TH/s per day divided by 1,000). The term was coined by Luxor Technologies in 2019 and has become the standard measure for mining profitability across the industry.

Hashprice is a function of four inputs: Bitcoin's price, network difficulty, the block subsidy (currently 3.125 BTC), and transaction fee volume. It rises when BTC price increases or difficulty drops, and falls when difficulty climbs or BTC price declines. In 2026, hashprice has fluctuated between roughly $30 and $34 per PH/s per day, reflecting tight margins across the industry.

A miner's breakeven hashprice is the level below which their operation becomes unprofitable. This is determined entirely by efficiency and electricity cost:

Breakeven Hashprice ($/PH/day) = Electricity Rate ($/kWh) × Efficiency (J/TH) × 24

For example, an Antminer S21 XP (13.5 J/TH) paying $0.065/kWh has a breakeven hashprice of $0.065 × 13.5 × 24 = $21.06/PH/day. With current hashprice around $32/PH/day, that machine still runs at a healthy margin. An Antminer T21 (19 J/TH) at the same rate breaks even at $29.64/PH/day, leaving almost no cushion.

Electricity Rates by Region

Electricity is the dominant operating cost for any mining operation. The following table shows typical industrial and mining-specific rates by region as of 2026. Rates vary based on contract terms, grid access, and whether the facility participates in demand-response programs.

For a country-by-country breakdown, see the mining profitability by country tool. The economics of regional electricity rates are explored in depth in our Bitcoin mining economics 2026 research article.

Post-Halving Economics and the 2028 Horizon

The April 2024 halving cut the block subsidy from 6.25 to 3.125 BTC, instantly halving the revenue available to miners. Unlike previous cycles, transaction fees have not meaningfully compensated: fee income accounts for less than 1% of total block rewards in most 2026 blocks, with average fees per block around 0.018 BTC.

This compression has driven three structural shifts in the mining industry:

• Rapid fleet upgrades to sub-15 J/TH hardware, retiring older machines that can no longer compete
• Migration to the lowest-cost power regions, with facilities in Paraguay, the Nordic countries, and the Middle East expanding capacity
• Diversification into AI/HPC workloads by publicly traded miners seeking to monetize data center infrastructure during low-hashprice periods

The next halving, expected around April 2028 at block height 1,050,000, will reduce the subsidy again to 1.5625 BTC per block. At that point, only the most efficient machines at the cheapest electricity rates will survive on block subsidy alone. Transaction fees and fee market dynamics will need to contribute meaningfully for the proof-of-work security budget to remain sustainable. For historical context on how halvings have reshaped the industry, see our halving economics analysis.

How to Calculate Your Breakeven

To run your own breakeven analysis, gather these inputs:

1. Your machine's hashrate (TH/s) and power consumption (watts), from the ASIC table above or your manufacturer's spec sheet
2. Your all-in electricity rate ($/kWh), including any hosting, cooling, or infrastructure fees
3. Your pool fee (typically 1–2%)
4. Hardware acquisition cost (for ROI calculation)

Plug these into the formulas above, using the current network hashrate (~1,040 EH/s) and BTC price. The breakeven electricity rate tells you your maximum sustainable power cost. If your actual rate is below the breakeven, the gap represents your operating margin. If it is above, you are mining at a loss and should consider upgrading hardware, negotiating a better power contract, or shutting down until conditions improve.

Note: These calculations cover operating expenses only (electricity and pool fees). A full profitability analysis must also account for hardware depreciation, facility costs, maintenance, insurance, and the time value of capital.

Miners who receive payouts in BTC and plan to hold long-term sometimes operate below the cash-flow breakeven, treating mining as a form of dollar-cost averaging into Bitcoin at below-market rates. This strategy carries significant risk if BTC price declines further. For miners looking to convert earnings to dollars, Bitcoin layer 2 solutions like Spark enable fast, low-cost settlement into stablecoins without the delays and fees of on-chain transactions.

Frequently Asked Questions

What is a good breakeven electricity rate for Bitcoin mining?

With current-generation hardware (13 to 19 J/TH) and mid-2026 hashprice levels around $32/PH/day, the breakeven electricity rate ranges from roughly $0.07/kWh for the least efficient machines to over $0.11/kWh for the best. Most profitable mining operations target all-in power costs below $0.07/kWh. At the US industrial average of $0.089/kWh, only machines at or below 15 J/TH efficiency maintain meaningful margins.

How does the Bitcoin halving affect mining breakeven?

Each halving cuts the block subsidy in half, which directly halves the revenue component of the breakeven equation. Unless BTC price doubles or network difficulty drops proportionally, the breakeven electricity rate for any given machine falls by roughly 50%. The April 2024 halving reduced the subsidy from 6.25 to 3.125 BTC. The next halving, expected around April 2028, will reduce it to 1.5625 BTC, further tightening margins for all but the most efficient operations.

What is hashprice and why does it matter for breakeven?

Hashprice measures the expected daily revenue per unit of hashrate, expressed as USD per PH/s per day. It combines BTC price, network difficulty, block subsidy, and transaction fees into a single number that represents what each terahash earns. Your breakeven hashprice equals your electricity cost multiplied by your machine's efficiency (J/TH) multiplied by 24 hours. If the market hashprice is above your breakeven, you are profitable. If it drops below, you are losing money on every hash.

Which ASIC miner has the lowest breakeven in 2026?

The Bitmain Antminer S21 XP Hyd (hydro-cooled) at 12.0 J/TH has the lowest breakeven of any widely available ASIC. The air-cooled Antminer S21 XP at 13.5 J/TH is the most efficient standard model. Both allow operators to remain profitable at electricity rates that would shut down older 18 to 20 J/TH machines. However, the S21 XP Hyd requires immersion cooling infrastructure that adds significant capital costs.

Is home Bitcoin mining profitable in 2026?

For most people, no. Residential electricity rates in the US average around $0.16/kWh, far above the breakeven threshold for any current ASIC at 2026 hashprice levels. In states like California and Hawaii where rates exceed $0.25/kWh, home mining is deeply unprofitable. The only exceptions are households with access to very cheap power (solar overproduction, off-peak time-of-use rates below $0.06/kWh, or behind- the-meter generation), and even then, noise and heat make residential deployment impractical for most setups.

How long does it take to recoup the cost of a mining ASIC?

At mid-2026 hashprice levels and competitive electricity rates ($0.065/kWh), an Antminer S21 XP generating roughly $5 to $8 per day in net profit after electricity takes 18 to 36 months to pay back its $4,500 to $5,500 purchase price. Less efficient or more expensive hardware takes longer. These estimates assume stable BTC price and network difficulty, both of which fluctuate significantly in practice. Rising difficulty compresses ROI timelines further, while BTC price appreciation can shorten them.

What happens when my ASIC hits breakeven and I can't profit?

When electricity costs exceed revenue, miners have several options: relocate to cheaper power, upgrade to more efficient hardware, curtail operations during high-rate periods and mine only during off-peak hours, or shut down entirely and sell the hardware on the secondary market. Some miners participate in demand-response programs where they earn credits for powering down during grid stress events, effectively subsidizing their mining during normal hours.
