Estimate what a miner earns after electricity and pool fees. Enter your hashrate, power draw and electricity price, then the network difficulty (or network hashrate), block reward and coin price to get daily, monthly and yearly profit, the cost to mine one coin and how long the hardware takes to pay for itself. No live data is fetched; enter current network figures yourself.

How to use the Crypto Mining Profitability Calculator
Enter your miner's hashrate and unit, its power draw in watts and your electricity price per kWh.
Add the pool fee and, for the break-even time, what the hardware cost.
Choose difficulty or network hashrate and enter the current value, plus the block reward and coin price.
Optionally add a monthly difficulty increase to see a more cautious projection.
Press Calculate to see profit per day and month, costs and the break-even time.
Mining profitability formulas
Coins per day (difficulty) = hashrate × 86,400 × block reward ÷ (difficulty × 232)
Coins per day (network hashrate) = (your hashrate ÷ network hashrate) × (86,400 ÷ block time) × block reward
Efficiency = watts ÷ TH/s, which equals joules per terahash (J/TH)
The 232 factor comes from the way SHA-256 difficulty is defined: at difficulty 1, a miner needs on average 232 hashes to find a block. Coins with other algorithms define difficulty differently, so use the network hashrate method for them.

Months are taken as 30.44 days (365.25 ÷ 12). Electricity is usually the largest ongoing cost, so the same miner can be profitable in one place and lose money in another.
Tips for a realistic estimate
Use wall power, measured at the outlet, not the chip power from a spec sheet; add fans or cooling if they run on the same bill.
Include transaction fees in the block reward if your pool pays them (FPPS and similar payout schemes do).
Plan for halvings: when a coin's block subsidy halves, revenue roughly halves overnight unless the price rises.
Model rising difficulty with the monthly increase field rather than assuming today's conditions last for years.
Frequently asked questions
How is mining revenue calculated?
For Bitcoin and other SHA-256 coins, expected coins per day = your hashrate (H/s) × 86,400 × block reward ÷ (difficulty × 2^32). With the network hashrate method, coins per day = (your hashrate ÷ network hashrate) × (86,400 ÷ block time) × block reward. Multiply by the coin price and subtract the pool fee to get revenue.
How do I calculate mining electricity cost?
Daily cost = power in watts × 24 hours ÷ 1,000 × price per kWh. A 3,500 W miner at $0.10/kWh uses 84 kWh a day and costs $8.40 a day, or about $256 a month.
What is the break-even electricity price?
It is the price per kWh at which mining revenue exactly equals the power bill: daily revenue ÷ daily kWh. If your rate is above it, the miner loses money every day regardless of hardware cost.
Why does difficulty growth matter?
As more hashrate joins a network the difficulty rises, so the same machine earns fewer coins each month. Adding even 2–3% a month can stretch the break-even time a lot, which is why the projection lets you model it.
Where do I find the difficulty and block reward?
Block explorers and mining pool dashboards show the current difficulty, network hashrate and average fees per block. For Bitcoin the block subsidy has been 3.125 BTC since the April 2024 halving and is expected to halve again around 2028.
Is the result exact?
No. Mining is probabilistic and the calculator shows expected values. Actual earnings vary with luck, pool payout method, hardware uptime, cooling, hashrate degradation and, above all, changes in coin price and difficulty.
Is crypto mining worth it?
It depends mostly on your electricity price, the efficiency of your hardware and the coin price. This page only does the math for the numbers you enter; it is not financial advice.
