Crypto Mining Calculator
Mining is only profitable as long as the value of the coins you mine outweighs what you burn in electricity. Enter how many coins your hardware produces per day, the current price, its power draw in watts and your price per kWh, and you instantly see your daily profit or loss.

公式
Profit = (coins/day × price) − ((watts ÷ 1000) × 24 × electricity price)
Revenue is simply the number of coins mined multiplied by the price per coin. Power cost is converted from watts to kilowatts by dividing by 1000, multiplied by 24 hours for a full day, and multiplied by your price per kWh. The difference between revenue and power cost is your daily profit — or loss. If you also enter a hardware cost, the calculator works out how many days it takes to pay that back.
ステップ解説
- 1Enter how many coins your hardware mines on average per day (read this from your mining pool or software).
- 2Enter the price per coin, the power draw in watts and your electricity price per kWh; the current BTC price is autofilled for you.
- 3Optionally enter the hardware cost to see the payback time of your equipment alongside your daily profit.
計算例
EXAMPLE: ASIC miner, 0.0005 BTC/day at € 58,000, 3000 W, € 0.25/kWh
→ Revenue € 29, power cost € 18, profit € 11 per day.
EXAMPLE: small GPU rig, altcoin, 0.003 coins/day at € 3,000, 1200 W, € 0.30/kWh
→ Revenue € 9.00, power cost € 8.64, profit only € 0.36 per day — the margin is razor-thin.
EXAMPLE: efficient ASIC with cheap power, 0.0006 BTC/day at € 58,000, 3250 W, € 0.15/kWh, hardware € 3,500
→ Revenue € 34.80, power cost € 11.70, profit € 23.10 per day — hardware paid back in roughly 152 days.
Reference table
| Electricity price per kWh | Daily power cost | Daily profit |
|---|---|---|
| € 0.10 | € 7.20 | € 21.80 |
| € 0.15 | € 10.80 | € 18.20 |
| € 0.20 | € 14.40 | € 14.60 |
| € 0.25 | € 18.00 | € 11.00 |
| € 0.30 | € 21.60 | € 7.40 |
| € 0.35 | € 25.20 | € 3.80 |
EXAMPLE based on 0.0005 BTC/day at € 58,000 and 3000 W draw; substitute the figures above for your own situation.
よくある間違い
- Only looking at revenue and forgetting power costs, especially at a high electricity price.
- Continuing to use an outdated "coins per day" figure while network difficulty has since risen, which overstates profit.
- Ignoring the coin's price volatility; a profitable day can suddenly turn into a loss if the price drops.
Limitations
- Coins per day depends on network difficulty, which constantly changes; you need to keep this figure current yourself, for example via your mining pool.
- The calculation doesn't account for hardware wear, cooling, maintenance or internet costs — these are extra expenses on top of the electricity price.
活用シーン
- Assessing whether it's worth keeping existing mining hardware running at the current electricity price.
- Comparing new hardware by calculating the payback time before you invest.
- Determining at what electricity price mining breaks even, for example before moving to a location with different energy rates.
よくある質問
Why doesn't this calculator include live network difficulty?
There is no reliable free API for real-time difficulty per hardware type; your mining pool or software usually shows your current expected daily output, and you enter that figure here yourself.
Why is my profit negative even though I'm still mining coins?
You can mine coins and still run at a loss: if the power cost (watts ÷ 1000 × 24 × price per kWh) exceeds the value of the coins mined, the result is negative. This often happens with a high electricity price or a falling coin price.
What is a good electricity price for profitable mining?
That depends entirely on your hardware's hash rate and efficiency plus the current price, so there's no fixed number. Enter your own figures and use the table of different electricity prices above to see at what rate your margin gets too thin.
Does the payback time also account for interest or depreciation?
No, the payback time is simply the hardware cost divided by daily profit; interest, depreciation, hardware value decline and any resale value are not factored in. Treat it as a rough indication, not a full investment analysis.
