Is Bitcoin Mining Profitable in 2026? Real Cost Calculator

Bitcoin mining in 2026 is a different game than it was two years ago. The April 2024 halving cut block rewards to 3.125 BTC, network difficulty keeps climbing, and electricity prices vary wildly depending on where you operate. So the question every miner asks remains the same: is it still worth plugging in a machine?

The answer depends on three numbers: your hashrate, your power consumption, and your electricity cost. In this guide, we break down exact profitability figures for six popular ASIC miners, across four electricity rates, so you can make a decision grounded in real math rather than speculation.

The Profitability Formula

Every mining profitability calculation comes down to one equation:

Profit/day = (Hashrate_TH × BTC_PER_TH_DAY × BTC_Price) - (Power_kW × 24 × $/kWh) - Pool_fees

Where:

Hashrate_TH is your machine's hashrate in terahashes per second (TH/s)
BTC_PER_TH_DAY is the amount of BTC earned per TH/s per day at current difficulty. As of early 2026, this sits around 0.00000054 BTC
BTC_Price is the current market price of Bitcoin. We use $64,000 for all calculations in this article
Power_kW is your machine's power draw in kilowatts
$/kWh is your all-in electricity cost per kilowatt-hour
Pool_fees typically range from 1% to 2% of gross revenue (we use 1% in our tables)

This formula tells you whether a machine generates more revenue than it costs to run. Simple in theory. The devil is in the details.

The Machines We Compare

Here are the six ASIC miners we analyze in this guide. They range from older workhorses still running in large farms to the latest generation of hydro-cooled units:

| Machine | Hashrate (TH/s) | Power (W) | Efficiency (J/TH) | Generation | |---|---|---|---|---| | Antminer S19 Pro | 110 | 3,245 | 29.5 | Previous gen | | Antminer S19 XP | 141 | 3,010 | 21.3 | Previous gen | | WhatsMiner M50S | 126 | 3,276 | 26.0 | Previous gen | | Antminer S21 | 200 | 3,500 | 17.5 | Current gen | | WhatsMiner M60S | 186 | 3,480 | 18.7 | Current gen | | Antminer S21 Hydro | 335 | 5,360 | 16.0 | Current gen (hydro) |

Efficiency, measured in joules per terahash (J/TH), is the single most important spec. A lower J/TH means the machine produces more hashes for every watt it consumes. This directly determines your breakeven electricity rate.

Daily Profitability Tables by Electricity Rate

Let's run the numbers. For each machine, we calculate daily gross revenue, daily electricity cost, and net daily profit after a 1% pool fee. BTC price: $64,000. BTC_PER_TH_DAY: 0.00000054.

At $0.03/kWh (Exceptional Rate)

This rate is achievable through direct energy contracts in regions like Kazakhstan, parts of Texas during off-peak hours, or stranded gas operations.

| Machine | Daily Revenue | Daily Elec. Cost | Net Profit/Day | Monthly Profit | |---|---|---|---|---| | S19 Pro (110 TH) | $3.77 | $2.34 | $1.39 | $41.70 | | S19 XP (141 TH) | $4.83 | $2.17 | $2.61 | $78.30 | | M50S (126 TH) | $4.32 | $2.36 | $1.91 | $57.30 | | S21 (200 TH) | $6.86 | $2.52 | $4.27 | $128.10 | | M60S (186 TH) | $6.38 | $2.51 | $3.81 | $114.30 | | S21 Hydro (335 TH) | $11.49 | $3.86 | $7.51 | $225.30 |

At three cents per kilowatt-hour, every machine on this list is profitable. Even the older S19 Pro still clears over $40 per month. The S21 Hydro, with its massive hashrate, generates the highest absolute profit.

At $0.05/kWh (Competitive Industrial Rate)

Common in parts of the US (Texas, Wyoming), Scandinavia, and some Middle Eastern hosting facilities.

| Machine | Daily Revenue | Daily Elec. Cost | Net Profit/Day | Monthly Profit | |---|---|---|---|---| | S19 Pro (110 TH) | $3.77 | $3.89 | -$0.17 | -$5.10 | | S19 XP (141 TH) | $4.83 | $3.61 | $1.17 | $35.10 | | M50S (126 TH) | $4.32 | $3.93 | $0.34 | $10.20 | | S21 (200 TH) | $6.86 | $4.20 | $2.59 | $77.70 | | M60S (186 TH) | $6.38 | $4.18 | $2.14 | $64.20 | | S21 Hydro (335 TH) | $11.49 | $6.43 | $4.95 | $148.50 |

Here we see the first casualty: the S19 Pro becomes unprofitable at $0.05/kWh. Its 29.5 J/TH efficiency simply cannot keep up post-halving. The M50S barely breaks even. Current-gen machines remain solidly profitable.

At $0.08/kWh (Standard Industrial Rate)

Typical industrial electricity rate in the US and much of Europe.

| Machine | Daily Revenue | Daily Elec. Cost | Net Profit/Day | Monthly Profit | |---|---|---|---|---| | S19 Pro (110 TH) | $3.77 | $6.23 | -$2.51 | -$75.30 | | S19 XP (141 TH) | $4.83 | $5.78 | -$1.00 | -$30.00 | | M50S (126 TH) | $4.32 | $6.29 | -$2.02 | -$60.60 | | S21 (200 TH) | $6.86 | $6.72 | $0.07 | $2.10 | | M60S (186 TH) | $6.38 | $6.68 | -$0.36 | -$10.80 | | S21 Hydro (335 TH) | $11.49 | $10.29 | $1.08 | $32.40 |

At eight cents, the picture shifts dramatically. All previous-gen machines are bleeding money. The S21 barely stays in the green, and the M60S dips slightly negative. Only the S21 Hydro remains comfortably profitable, thanks to its class-leading 16 J/TH efficiency.

At $0.12/kWh (US Residential Average)

The average residential rate across the United States. Many home miners pay this or more.

| Machine | Daily Revenue | Daily Elec. Cost | Net Profit/Day | Monthly Profit | |---|---|---|---|---| | S19 Pro (110 TH) | $3.77 | $9.35 | -$5.63 | -$168.90 | | S19 XP (141 TH) | $4.83 | $8.67 | -$3.89 | -$116.70 | | M50S (126 TH) | $4.32 | $9.43 | -$5.17 | -$155.10 | | S21 (200 TH) | $6.86 | $10.08 | -$3.29 | -$98.70 | | M60S (186 TH) | $6.38 | $10.02 | -$3.70 | -$111.00 | | S21 Hydro (335 TH) | $11.49 | $15.44 | -$4.06 | -$121.80 |

No machine is profitable at residential electricity rates. This is the harsh reality of post-halving mining. If you are paying $0.12/kWh or more, you are losing money on every machine, every day. Home mining at standard residential rates is not viable in 2026 without a significant BTC price increase.

Breakeven Electricity Rate by Machine

The breakeven rate is the maximum you can pay per kWh before a machine starts losing money. It is directly tied to efficiency (J/TH): the lower the J/TH, the higher the breakeven rate, and the more resilient the machine is to electricity price fluctuations.

| Machine | Efficiency (J/TH) | Breakeven $/kWh | Verdict | |---|---|---|---| | S19 Pro (110 TH) | 29.5 | $0.048 | Obsolete for most miners | | S19 XP (141 TH) | 21.3 | $0.066 | Marginal, needs cheap power | | M50S (126 TH) | 26.0 | $0.054 | Obsolete for most miners | | S21 (200 TH) | 17.5 | $0.081 | Profitable with industrial rates | | M60S (186 TH) | 18.7 | $0.075 | Profitable with competitive rates | | S21 Hydro (335 TH) | 16.0 | $0.088 | Most resilient option |

The breakeven formula is straightforward:

Breakeven $/kWh = (BTC_PER_TH_DAY × BTC_Price × (1 - pool_fee%)) / (J/TH × 24 / 1000)

Key insight: the S21 Hydro can tolerate electricity costs nearly twice as high as the S19 Pro before becoming unprofitable. Efficiency is survival.

How a Mining Proxy Shifts the Numbers

A mining proxy sits between your miners and the pool, optimizing share submission, reducing stale shares, and improving network efficiency. The result? Typically a 2 to 3% increase in effective revenue.

That might sound modest, but at tight margins it can be the difference between profit and loss. Here is what a +2.5% revenue boost does to breakeven rates:

| Machine | Breakeven (Standard) | Breakeven (With Proxy) | Gain | |---|---|---|---| | S19 Pro | $0.048 | $0.049 | +$0.001 | | S19 XP | $0.066 | $0.068 | +$0.002 | | M50S | $0.054 | $0.055 | +$0.001 | | S21 | $0.081 | $0.083 | +$0.002 | | M60S | $0.075 | $0.077 | +$0.002 | | S21 Hydro | $0.088 | $0.090 | +$0.002 |

For a farm running 100 S21 units, that 2.5% boost translates to roughly $5,100 extra revenue per month at $0.05/kWh. Over a year, that is over $61,000 in additional income from the same hardware and the same electricity bill.

The proxy also gives you better visibility into which payment method actually maximizes your payout, since FPPS and PPS+ perform differently depending on transaction fee levels.

You can test a proxy setup on the Minent demo or create an account on the proxy platform to see real-time results on your own machines.

ROI Table: How Long to Pay Off Your Machine?

Buying an ASIC is a capital investment. The machine price matters just as much as daily profit. Here are approximate ROI timelines at $0.05/kWh (a competitive rate):

| Machine | Approx. Price (USD) | Daily Profit @ $0.05 | ROI (Months) | Verdict | |---|---|---|---|---| | S19 Pro (110 TH) | $350 - $500 | -$0.17 | Never | Not recommended | | S19 XP (141 TH) | $600 - $900 | $1.17 | 17 - 26 mo | Acceptable if cheap | | M50S (126 TH) | $500 - $700 | $0.34 | 49 - 69 mo | Too slow | | S21 (200 TH) | $2,800 - $3,500 | $2.59 | 36 - 45 mo | Reasonable | | M60S (186 TH) | $2,200 - $2,800 | $2.14 | 34 - 44 mo | Reasonable | | S21 Hydro (335 TH) | $5,500 - $7,000 | $4.95 | 37 - 47 mo | Best for scale |

At $0.03/kWh, these ROI timelines roughly cut in half. At $0.08/kWh, most machines never pay themselves off.

The S19 XP stands out as the best value play if you can find units at the low end of the price range and have access to cheap electricity. For serious operations, the S21 and S21 Hydro offer the best long-term positioning because their efficiency gives them room to stay profitable even as difficulty rises.

Variables That Change Everything

The tables above are snapshots. Three variables can shift profitability dramatically:

1. Bitcoin Price

Every $10,000 move in BTC price shifts revenue by roughly 15%. At $80,000, many machines that are marginal today become solidly profitable. At $50,000, even the S21 struggles at industrial rates. Price is the single biggest lever, but also the one you control least.

2. Network Difficulty

Difficulty adjusts every 2,016 blocks (roughly two weeks) based on total network hashrate. If new machines flood the network, difficulty rises and BTC_PER_TH_DAY drops. The value of 0.00000054 BTC per TH/day used in this article is a snapshot. Over 2025-2026, difficulty has generally trended upward by 3 to 5% per month.

3. Transaction Fees

Transaction fees are the wild card. During periods of high on-chain activity (Ordinals inscriptions, Runes minting, BRC-20 tokens), transaction fees can temporarily double or triple block rewards. These fee spikes can turn an unprofitable machine profitable overnight, but they are unpredictable and temporary.

The combination of these three variables is why static profitability calculators only tell part of the story. The best miners plan for the worst case (high difficulty, low fees) and benefit from the best case (fee spikes, price rallies).

Practical Recommendations for 2026

Based on the data above, here is what we recommend depending on your situation:

If you have electricity below $0.05/kWh: You are in a strong position. Current-gen machines (S21, M60S, S21 Hydro) are solidly profitable. Even previous-gen S19 XP units can make sense if purchased cheaply on the secondary market.

If you pay $0.05 to $0.08/kWh: Only current-gen machines make sense. Focus on efficiency: the S21 and S21 Hydro should be your primary targets. Use a mining proxy to squeeze out the extra 2-3% that keeps you above breakeven.

If you pay above $0.08/kWh: Mining is not profitable at current BTC prices and difficulty. Either negotiate a better electricity rate, wait for a significant BTC price increase, or consider cloud mining alternatives. Do not buy hardware at these rates.

Conclusion

Bitcoin mining profitability in 2026 comes down to two things: machine efficiency and electricity cost. Post-halving, the margin for error is razor-thin. The S19 Pro and M50S are functionally obsolete for anyone paying above $0.05/kWh. The S21 series represents the minimum viable efficiency for most miners.

The good news: if you can secure competitive electricity rates and run efficient hardware, mining remains profitable. Tools like mining proxies, optimized pool payment methods, and proper thermal management can add meaningful percentage points to your bottom line.
