Every week someone messages our desk with the same question, phrased a hundred ways: how much will this miner actually make me? They have usually already typed "bitcoin mining calculator" into Google, plugged a machine into one of the free tools, and come away with a number that turned out to be wrong the moment real electricity bills arrived. The tools are not lying. They are just answering a simpler question than the one that matters.
An ASIC mining calculator tells you what a machine earns against the live network. What it usually leaves out is the part that decides whether you make money: your real all-in power rate, your pool fee, and the fact that difficulty climbs while you sleep. This guide shows you how to run the calculation properly, with the actual June 2026 network numbers, worked examples at real electricity rates, and the three inputs that change the answer more than the hardware does.

What a Bitcoin mining calculator actually does
A Bitcoin mining calculator estimates how much a given amount of hashrate earns over a period of time. You give it three things, your machine's hashrate, its power draw, and your electricity rate, and it returns an estimate of revenue, power cost, and the profit left over. That is the whole job.
Under the hood, the calculator takes the current network difficulty and block reward, works out what share of the network your hashrate represents, and multiplies that share by the daily Bitcoin issued to all miners. It converts that to dollars at the current Bitcoin price, subtracts your power cost, and shows the result. Most tools wrap all of that into a single figure called hashprice, the dollar value of one unit of hashrate per day, which makes the revenue side a quick multiplication. The accuracy problem is never the revenue side. It is the cost side, and the assumption that today's numbers hold tomorrow.
The five inputs that decide your result
A profit estimate is only as good as what you feed it. These are the five inputs that move the number, in roughly the order they matter:

The five inputs that decide your result
A profit estimate is only as good as what you feed it. These are the five inputs that move the number, in roughly the order they matter:
- Hashrate how much work your machine does, in terahashes per second (TH/s) for Bitcoin. Higher hashrate earns a larger share of the network reward.
- Power draw how many watts the machine pulls at the wall. This is the cost engine, and it runs 24 hours a day whether Bitcoin goes up or down.
- Electricity rate your real all-in cost per kilowatt-hour. Not the headline supply rate, the full delivered rate with fees and taxes. This is the single biggest swing factor.
- Pool fee the cut your mining pool takes, usually 0 to 2.5 percent. Small, but real, and most free calculators ignore it.
- Network difficulty and Bitcoin price the two moving targets. Both change constantly, and a calculator only captures a single moment. We cover where to pull current values next.
The input people get wrong most often. Electricity rate. Operators plug in the supply portion of their bill ($0.07) and forget the delivery charges, demand fees, and taxes that push the real number to $0.11 or higher. Always use your total bill divided by total kilowatt-hours used, not the rate printed at the top.
The June 2026 network numbers to plug in
A calculator needs current network values to be accurate. Here are the figures as of June 3, 2026. If you are reading this later, pull fresh numbers from a network data source before trusting any estimate, because all four of these move.
| Network input | Value (June 3, 2026) | What it affects |
|---|---|---|
| Bitcoin price | ~$69,300 | Converts your mined BTC to dollars |
| Network difficulty | 138.96 trillion | Your share of the total reward |
| Network hashrate | ~1 ZH/s (1,000 EH/s) | The competition you mine against |
| Hashprice | ~$37.52 / PH per day | Revenue per unit of hashrate |
| Block reward | 3.125 BTC | Issued every block since the 2024 halving |
One note on timing. The network difficulty was set to adjust again around June 13, 2026, with estimates pointing to a drop toward roughly 125.94 trillion. A difficulty drop raises every miner's revenue per terahash, so calculations made just before and just after an adjustment can differ by several percent. This is exactly why a calculator is a snapshot, not a forecast.
Worked example: the math from start to finish
Let us run a real machine through the full calculation by hand, so the calculator stops being a black box. Take the Antminer S23 Hydro: 580 TH/s at 5,510 watts, the most efficient air-or-hydro Bitcoin miner widely available in 2026.
Step one, revenue. Hashprice is about $37.52 per petahash per day. The S23 Hydro produces 580 TH/s, which is 0.58 PH/s. So daily revenue is 0.58 times $37.52, or about $21.76 per day before costs. Step two, power cost. The machine draws 5,510 watts, which over 24 hours is 132.24 kilowatt-hours per day. At an electricity rate of $0.08 per kWh, that is 132.24 times $0.08, or about $10.58 per day in power.
Step three, profit. Revenue minus power cost is $21.76 minus $10.58, which leaves about $11.18 per day, or roughly $335 per month per machine, before pool fees. Apply a 1 percent pool fee and you lose about $0.22 a day, a small but real trim. That is the entire calculation. Every mining calculator is doing exactly this; the only question is whether the inputs you gave it match your reality.
Cost to mine one Bitcoin. Flip the same math around and the S23 Hydro produces Bitcoin for roughly $33,700 each at $0.08 per kWh, against a spot price near $69,300. That gap is the real margin, and it is why efficient hardware on cheap power still works even in a soft market.

How to calculate your mining profit, step by step
The worked example above used one machine. Here is the same process as a repeatable method you can run for any miner, at your own rate, in about five minutes. Keep your last power bill and your machine's spec sheet nearby and work through it in order.
Step 1: Get your machine's two hardware numbers
You need hashrate and power draw, both printed on the spec sheet or the product page. Hashrate is in TH/s for Bitcoin (for example, 580 TH/s). Power draw is in watts at the wall (for example, 5,510 W). Use the rated figures, but know that real-world output runs within a few percent of the rating, Bitmain quotes plus or minus 3 percent on hashrate, so treat the result as a center point, not a guarantee.
Step 2: Find your real, all-in electricity rate
This is the step that decides whether your estimate matches reality. Do not use the supply rate at the top of your bill. Take the total amount you paid last month and divide it by the total kilowatt-hours you used that month. The result is your all-in rate, including delivery charges, demand fees, and taxes, and it is usually higher than the headline number. If your bill says $0.07 supply but the all-in works out to $0.11, the $0.11 is the figure that matters.
Step 3: Pull today's network numbers
A calculator needs the current Bitcoin price, network difficulty, and block reward to convert your hashrate into dollars. The fastest shortcut is hashprice, the dollar value of one petahash per day, which already bundles price, difficulty, and reward into one figure. As of June 3, 2026 it is about $37.52 per PH per day. Pull a fresh figure if you are reading this later, because it moves with every block.
Step 4: Work out daily revenue
Convert your hashrate to petahashes (divide TH/s by 1,000), then multiply by hashprice. A 580 TH/s machine is 0.58 PH/s, so 0.58 times $37.52 is about $21.76 a day in revenue. That is what the hardware earns before you pay for a single kilowatt.
Step 5: Work out daily power cost
Multiply your power draw in kilowatts by 24 hours to get daily kilowatt-hours, then multiply by your all-in rate. A 5,510 W machine is 5.51 kW, times 24 is 132.24 kWh a day, times $0.08 is about $10.58 a day in electricity. This number runs whether Bitcoin rises or falls, which is why it is the cost you most need to control.
Step 6: Subtract, then sanity-check
Daily profit is revenue minus power cost: $21.76 minus $10.58 leaves about $11.18 a day, roughly $335 a month. Then trim for the things free calculators skip: subtract your pool fee (0 to 2.5 percent of revenue), and mentally shave a little more for occasional downtime and rising difficulty. What remains is a realistic, slightly conservative estimate, which is exactly what you want before spending thousands on hardware.
The 30-second version. Daily profit = (hashrate in PH/s x hashprice) minus (power in kW x 24 x your all-in rate), then take off your pool fee. Everything else a calculator does is presentation around that one line.
Run those six steps and you are no longer trusting a black box; you can check any calculator's output against your own math and spot immediately when an input is off. The most common mistake, by far, is Step 2: using the headline electricity rate instead of the all-in rate, which makes every downstream number look better than your bank account will.
Profit by machine and electricity rate
Here is the output for two current flagship miners across the electricity rates that matter, using the June 2026 hashprice. These are the numbers a calculator would return if you fed it accurate inputs. Net figures are daily profit per machine, before pool fees.
Antminer S23 Hydro, 580 TH/s at 5,510 watts, about $21.76 a day in revenue:
The worked example above used one machine. Here is the same process as a repeatable method you can run for any miner, at your own rate, in about five minutes. Keep your last power bill and your machine's spec sheet nearby and work through it in order.

Profit by machine and electricity rate
Here is the output for two current flagship miners across the electricity rates that matter, using the June 2026 hashprice. These are the numbers a calculator would return if you fed it accurate inputs. Net figures are daily profit per machine, before pool fees.
Antminer S23 Hydro, 580 TH/s at 5,510 watts, about $21.76 a day in revenue:
| Electricity rate | Power cost / day | net profit / day | net / month |
|---|---|---|---|
| $0.04 / kWh | $5.29 | +$16.47 | +$494 |
| $0.07 / kWh | $9.26 | +$12.50 | +$375 |
| $0.08 / kWh | $10.58 | +$11.18 | +$335 |
| $0.10 / kWh | $13.22 | +$8.54 | +$256 |
| $0.12 / kWh | $15.87 | +$5.89 | +$177 |
Antminer S21 XP, 270 TH/s at 3,645 watts, about $10.13 a day in revenue:
| electricity rate | powe cost / day | net profit / day | net / month |
|---|---|---|---|
| $0.04 / kWh | $3.50 | +$6.63 | +$199 |
| $0.07 / kWh | $6.12 | +$4.01 | +$120 |
| $0.08 / kWh | $7.00 | +$3.13 | +$94 |
| $0.10 / kWh | $8.75 | +$1.38 | +$41 |
| $0.12 / kWh | $10.50 | -$0.37 | -$11 |
Read the bottom row of the second table carefully. The S21 XP goes negative at $0.12 per kWh. Same machine, same network, same Bitcoin price; the only thing that changed was the power rate, and it turned a profit into a loss. That is the whole point of running the calculation with your real number. For the full ranking of every current miner by profitability, the best Bitcoin miners of 2026 breakdown runs all of them side by side.
Where every calculator gets it wrong
Honesty section, because a calculator is a useful tool with three real blind spots, and knowing them is what separates a realistic estimate from a disappointing one.
First, it assumes today's difficulty forever. Network difficulty has trended upward for most of Bitcoin's history, which means the same machine earns slightly less every couple of weeks as difficulty climbs. A calculator showing $335 a month today is not promising $335 a month next year. Second, it assumes a fixed Bitcoin price, when price is the most volatile input of all; the revenue line moves the instant the market does. Third, most free calculators quietly ignore pool fees, hardware failures, downtime, and the gap between your headline electricity rate and your real all-in rate.
None of this makes the tool useless. It makes it a snapshot. The right way to use a mining calculator is to run it with conservative inputs, your real all-in power rate, a small difficulty-growth buffer, and a Bitcoin price you would not be shocked to see, and then treat the output as the optimistic edge of a range rather than a promise.
Frequently asked questions How accurate is a Bitcoin mining calculator?
It is accurate for a single moment, given accurate inputs. The revenue side is reliable because it is based on current network difficulty and price. The profit side is only as good as the electricity rate you enter, and every estimate assumes difficulty and price hold steady, which they never do. Treat the output as a snapshot, not a forecast, and use your real all-in power rate rather than the headline rate on your bill.
What inputs do I need for a mining calculator?
Three at minimum: your machine's hashrate (in TH/s for Bitcoin), its power draw (in watts), and your electricity rate (in dollars per kWh). For a sharper result, add your pool fee, usually 0 to 2.5 percent. The calculator supplies the network values (difficulty, price, block reward) automatically, though you should confirm they are current.
How much can I make mining Bitcoin in 2026?
It depends entirely on your hardware and power rate. At June 2026 numbers, an Antminer S23 Hydro nets roughly $335 a month at $0.08 per kWh and $177 at $0.12. A less efficient machine like the S21 XP can drop to break-even or a small loss at $0.12. There is no single answer; run your own machine and rate through the math.
What is hashprice?
Hashprice is the dollar value of one unit of hashrate per day, usually quoted per petahash per second (PH/s). In June 2026 it sits around $37.52 per PH per day. It bundles block reward, transaction fees, network difficulty, and Bitcoin price into a single figure, so daily revenue is just your hashrate times hashprice. It is the fastest way to estimate the revenue side of any mining calculation.
Why does my real profit come out lower than the calculator says?
Almost always one of three reasons: your real all-in electricity rate is higher than the figure you entered, the calculator ignored pool fees and downtime, or network difficulty rose since you ran it. The revenue side is rarely the problem. Re-run the math with your total bill divided by total kilowatt-hours used, and you will usually find the gap.
Does the calculator account for the Bitcoin halving?
Only indirectly. The block reward dropped to 3.125 BTC at the April 2024 halving and stays there until the next halving in 2028, so the current block reward is already baked into today's numbers. What a calculator cannot do is predict the price and difficulty changes that a future halving will bring. For that planning horizon, see our 2028 halving preparation guide.
Is Bitcoin mining still profitable in 2026?
For efficient hardware on power below about $0.10 per kWh, yes, even with Bitcoin near $69,000 and difficulty at record highs. Above $0.12 at home, it gets marginal fast for all but the newest machines, which is when hosting on industrial power becomes the better route. The honest answer is that profitability is a function of your rate, not a yes or no for everyone.
What electricity rate should I use in the calculator?
Your real all-in rate: take your most recent power bill, divide the total amount owed by the total kilowatt-hours used, and use that figure. It will usually be higher than the supply rate printed at the top of the bill, because it includes delivery charges, demand fees, and taxes. Using the headline rate instead of the all-in rate is the most common reason real profit comes in below the estimate.
The bottom line
A Bitcoin mining calculator is the right first step, as long as you understand what it is telling you. It is a snapshot of what a machine earns against today's network at the inputs you provide, and the input that matters most is the one people get wrong most often: their real, all-in electricity rate. Get that number right, add a buffer for rising difficulty, and the output becomes genuinely useful.
Run the math, then run it again at a hosted rate of $0.07 to $0.08 and compare. For a lot of operators, that second calculation is the one that actually changes the decision. If you want a hand turning an estimate into a deployment, the same team that runs 30,000-plus miners will tell you what a specific machine earns at your rate before you buy anything.
