About the Bitcoin Mining Profitability Calculator
Before you buy a miner, it helps to know whether it would earn more than it costs to run. This calculator estimates that from the numbers on the miner's spec sheet and your own costs. Type the hash rate in terahashes per second, the power the miner draws in watts, your price per kilowatt-hour, the Bitcoin price, the current network difficulty, the block reward and your pool fee. You get the expected bitcoin per day, the revenue, the electricity cost, the profit per day, month and year, and two useful limits: the Bitcoin price and the electricity price at which you only break even. It is a formula, not a promise, since mining is random, difficulty changes every two weeks and the price moves. Nothing is looked up, so you type each value yourself.

How to use the Bitcoin Mining Profitability Calculator
- 1Enter the miner's hash rate in TH/s and its power use in watts.
- 2Enter your electricity price per kWh, including delivery charges.
- 3Enter the Bitcoin price and the network difficulty in trillions (check a block explorer).
- 4Check the block reward, your pool fee and any monthly hosting costs.
- 5Read the profit per day, month and year, and the break-even price and electricity price.
What decides if mining pays
Three things decide profit: how efficient the machine is, how cheap your power is, and the price of bitcoin. Efficiency is energy per unit of hash power, shown here in joules per terahash. A newer machine at 20 J/TH uses much less power than an old one at 80 J/TH for the same hash rate, and that gap is the difference between profit and loss when power is expensive.
Network difficulty acts like a competition meter. When more miners join, difficulty rises and your share of the reward shrinks. When the price rises, miners join, and the gain is slowly shared out. That is why profits tend to move toward the cost of the least efficient machines still running.
Tips for realistic numbers
- Use the price you really pay per kWh including taxes and delivery, not the headline rate.
- Add hosting and cooling as monthly costs if you do not run the machine at home.
- Test a lower price and a higher difficulty to see how safe the plan is.
- Remember the halving: the reward is cut in half every 210,000 blocks, which halves income overnight.
Tools that help the plan
Check your power bill with the Electricity Cost Calculator, and see how long to the next reward cut with the Bitcoin Halving Countdown. To turn the bitcoin earned into money use the Bitcoin Price Converter, and for the machine's payback time the ROI Calculator gives the return on your purchase.

Frequently asked questions
How is the daily bitcoin amount calculated?
Expected BTC per day = hash rate x 86,400 x block reward / (difficulty x 2^32). In words: your share of the network's hash power multiplied by the 144 blocks or so mined in a day. The calculator uses this formula with your numbers.
Where do I find the current difficulty?
Any Bitcoin block explorer or mining statistics page shows it. Type it in trillions, for example 100 for 100 T. The default of 100 T is only an example, so replace it with the current number.
Does the block reward include transaction fees?
By default only the subsidy of 3.125 BTC is used. Fees add a few percent on average, and more in busy times. To include them, raise the reward a little, for example to 3.25.
What does break-even mean here?
The break-even price is the Bitcoin price at which revenue equals your costs, so profit is zero. The break-even electricity price is the highest price per kWh you could pay and still not lose money.
Why is real mining income different?
Mining is random. Pools smooth it out, but there are rounding rules, payout thresholds and difficulty changes. Hardware also loses efficiency, and failed or offline days cut income.
Does it include the cost of the miner?
No. It shows running profit. To see the payback time, divide the machine price by the profit per day, and add cooling, internet and your time.
Is this financial advice?
No. It is a planning calculator, and mining can lose money fast when the price falls or difficulty rises.
