How to Use This Calculator
Select Your Hardware or Enter Manually
Choose a popular ASIC miner from the Hardware Preset dropdown to auto-fill hashrate and power consumption, or select 'Custom' and enter your miner's specifications manually. You can find these values on the manufacturer's spec sheet.
Enter Your Electricity Cost
Check your utility bill for your cost per kilowatt-hour (kWh). This is the most important variable for profitability. Enter your pool fee percentage (typically 1% for most major pools). If you know your hardware purchase cost, enter it to see your break-even / ROI timeline.
Review Results Instantly
The calculator auto-updates as you type. Review the profitability verdict (Profitable / Breaking Even / Unprofitable), your daily net profit, and the cost breakdown donut chart showing what percentage of revenue goes to electricity, pool fees, and net profit.
Use Advanced Mode for Scenario Planning
Toggle to Advanced mode to override the default Bitcoin price, network difficulty, and block reward. Model optimistic and pessimistic scenarios — for example, see how your profitability changes if BTC doubles in price or if network difficulty increases by 20%.

Frequently Asked Questions
How accurate is this Bitcoin mining calculator?
This calculator uses the standard mining revenue formula based on your hashrate, network difficulty, and block reward. The accuracy of the output depends entirely on the accuracy of the inputs. The biggest variables are Bitcoin's price (extremely volatile), network difficulty (adjusts every ~2 weeks and trends upward over time), and your actual electricity rate. Treat all projections as estimates for planning purposes only, not as guaranteed income. Real-world results will vary as all of these inputs change continuously. Always model multiple scenarios, including conservative ones.
What is hash price and why does it matter?
Hash price (expressed as $/TH/day) is the revenue generated per terahash of mining power per day. It is a standardized metric that allows miners to compare the profitability of different coins, hardware, and time periods independent of individual machine specifications. Hash price is determined by three factors: Bitcoin's USD price, the block reward, and the total network hashrate (difficulty). When Bitcoin's price rises, hash price rises. When the network adds more hashrate, hash price falls. Miners often use hash price to quickly assess whether their operation is profitable relative to their operating costs (expressed as $/TH/day in electricity costs).
What happens to my mining income after the Bitcoin halving?
After a Bitcoin halving, the block reward decreases by 50%. If nothing else changes (BTC price, difficulty, your hashrate), your daily BTC income will be cut in half overnight. This means your mining revenue in USD will also halve unless the Bitcoin price rises to compensate. Historically, Bitcoin's price has eventually risen significantly after each halving, but this is not guaranteed and often takes months or years to materialize. Miners approaching a halving should stress-test their operations at 50% of current BTC earnings to ensure they can remain profitable through the post-halving period.
Why is my electricity cost so important?
Electricity is the primary operating cost for Bitcoin mining. Unlike hardware (a one-time cost), electricity is an ongoing cost that never stops. Industrial-scale miners often pay $0.02–$0.05/kWh using cheap hydropower, geothermal, or stranded natural gas. Retail electricity customers typically pay $0.10–$0.20/kWh in most developed countries. This 4–10x difference in electricity cost is the primary reason industrial miners can remain profitable when retail miners cannot. Reducing your electricity cost by even $0.02/kWh can translate to hundreds or thousands of dollars in annual savings per machine. This is why mining farm location is one of the most critical strategic decisions in the industry.
Should I mine solo or join a mining pool?
For the vast majority of miners, pool mining is the only practical option. Solo mining means you only receive a reward when your hardware finds an entire block, which at typical retail-scale hashrates could take years or even decades. A miner with 100 TH/s on a network of 800 EH/s has roughly a 1-in-8,000,000 chance of finding each block — or about once every 55,000 days (150+ years) on average. Pool mining combines your hashrate with thousands of other miners, producing much more consistent and predictable income in exchange for a pool fee (usually 1–3%). This calculator models pool mining.
What is break-even (ROI) for mining hardware?
The hardware break-even period (also called ROI days) is the number of days of net profit required to fully recover your initial hardware investment. For example, if you spend $5,000 on an ASIC miner and it earns $10 net profit per day, your break-even period is 500 days. After that point, all further net profit is pure return on investment. Miners generally seek hardware break-even periods of 12–24 months for new machines. Longer break-even periods represent higher financial risk, as the machine may become obsolete or network conditions may deteriorate before the investment is recovered. Enter your hardware cost in the optional field to see this calculation.
