Can a Bitcoin miner pay for its own electricity? That is the first question to answer before you plug one in. Power is the biggest running cost of mining, and it is due every month.
The Bitcoin Mining Calculator takes your hash rate, power draw, electricity rate, and pool fee. It estimates monthly revenue, monthly power cost, and monthly net profit. It is a quick first check for home miners and anyone pricing an ASIC machine.

What the Calculator Does
The tool compares what a miner might earn with what it costs to run. Its results card, titled "Mining Profit Estimate (Example Revenue Rate)," shows three monthly figures.
- Monthly Net Profit: revenue after pool fees, minus the power bill. It turns red when negative.
- Monthly Power Cost: the electricity the miner uses in a 30-day month.
- Estimated Monthly Revenue (at $2.20 per TH/s): income from your hash rate after the pool fee.
- Sample results load with the page: 110 TH/s, 3,250 watts, $0.08 per kWh, and a 2% fee.
How to Use It, Step by Step
- Enter the miner's speed in Hash Rate (TH/s). You can find it on the spec sheet.
- Enter the wall power draw in Power Consumption (Watts).
- Enter your price per kilowatt hour in Electricity Cost ($/kWh). Check your utility bill.
- Enter your mining pool's cut in Pool Fee (%).
- Press Calculate Mining Profit to update the results.
Results change only when you press the button. A gray note above the button says the revenue rate is an example, not live data.
The Mining Profit Formula
The tool uses a fixed example revenue rate of $2.20 per TH/s per month. It then subtracts the cost of running the machine around the clock for 30 days.
TH/s × $2.20 × (1 - Fee %)-kW × 720 hrs × $/kWh=Monthly Net Profit
- Monthly revenue = hash rate × $2.20 × (1 - pool fee ÷ 100).
- Monthly kWh = watts ÷ 1,000 × 24 hours × 30 days.
- Monthly power cost = monthly kWh × electricity rate.
- Monthly net profit = monthly revenue - monthly power cost.
The $2.20 figure is a fixed example rate built into the tool. It is not pulled from live price, difficulty, or hashprice data.
Worked Example
Luis is pricing a 200 TH/s miner that draws 3,500 watts. His example power rate is $0.12 per kWh, and his pool charges 1.5%.
| Result | Calculation | Output |
|---|
| Estimated Monthly Revenue | 200 × $2.20 × 0.985 | $433.40 |
| Monthly Energy Use | 3.5 kW × 24 × 30 | 2,520 kWh |
| Monthly Power Cost | 2,520 × $0.12 | $302.40 |
| Monthly Net Profit | $433.40 - $302.40 | $131.00 |
Now say Luis pays $0.20 per kWh instead. The power cost jumps to $504.00, and the profit card shows -$70.60 in red. That is a loss of $70.60 a month.
How to Read the Results
Estimated Monthly Revenue is already reduced by the pool fee. Its label names the $2.20 example rate, so it does not reflect today's market.
Monthly Power Cost is the most reliable result, because it uses your own numbers. It assumes the miner runs 24 hours a day for 30 days.
Monthly Net Profit is what is left before hardware, cooling, internet, and repair costs. A loss shows with a leading minus, such as -$70.60, and the card turns red.
What Moves Mining Profit
Electricity is the lever you control most. In Luis's case, revenue covers power up to about $0.17 per kWh. You can find your own break-even rate by dividing revenue by monthly kWh.
To price the power side more closely, use the kWh cost calculator. The hash rate calculator helps you compare machines by speed.
Real mining income also changes with the Bitcoin price, network difficulty, and the block reward. The reward is cut in half about every four years, in an event called the halving. None of these are inputs here, so treat the revenue figure as a placeholder.
A miner is an investment, so the purchase price matters. The payback period calculator shows how many months it takes to earn back that cost. The investment return calculator measures the overall gain.
If you hold the coins you mine, the crypto profit calculator tracks their value. See more tools in the finance and business calculator hub.
Mining and crypto prices carry real risk, and past results do not predict future ones. Mining rewards and coin sales may also have tax effects, so ask a tax professional.
Limitations and Assumptions
- Revenue uses a fixed $2.20 per TH/s per month. It ignores the Bitcoin price, difficulty, fees, and halvings.
- The month is 30 days of nonstop running, with no downtime.
- Hardware cost, cooling, and repairs are not included, so there is no payback or ROI figure.
- Blank fields, negative values, a hash rate under 1 TH/s, or a fee above 100% show a red message. All results then read N/A.
- There are no copy or reset buttons.
- There is no daily or yearly view. Multiply the monthly figure by 12 for a simple year.
FAQs About the Bitcoin Mining Calculator
Does the calculator use live Bitcoin prices?
No. Revenue comes from the fixed example rate, so it never changes with the market. Check a current mining revenue figure before you buy hardware.
What is TH/s?
TH/s means terahashes per second, or trillions of guesses each second. It measures how fast a miner works. A higher number earns a larger share of pool rewards.
How is the power cost worked out?
The tool converts watts to kilowatts and multiplies by 720 hours. It then multiplies by your rate. A 3,250-watt miner uses 2,340 kWh in that month.
Why does my profit show a negative number?
Your power cost is higher than the estimated revenue. Try a lower electricity rate or a more efficient machine to see where profit turns positive.
What does the pool fee do?
Pools combine many miners and share the rewards. They keep a small percentage as a fee. The tool takes that percentage off your revenue.
Is home mining worth it?
It depends on your power rate, your hardware cost, and the market. This tool gives a rough monthly view only. It cannot tell you whether mining will pay off.
