Bitcoin Mining Profitability Calculator
Estimate your daily Bitcoin mining profit by entering your miner's hash rate, power draw, electricity rate, and current BTC price. Ideal for evaluating whether a mining rig is profitable before or after purchase.
About this calculator
Bitcoin mining profitability depends on two competing forces: revenue earned from hashing and costs paid for electricity. The formula used here is: Daily Profit = (hashRate × 0.00000006 × btcPrice) − (powerConsumption × 24 × electricityCost / 1000). The constant 0.00000006 is a simplified approximation of daily BTC earned per TH/s based on typical network difficulty and block reward. The electricity cost term converts watt-hours to kilowatt-hours (dividing by 1,000) and multiplies by 24 hours to get daily energy expense. If the result is positive, your miner earns more than it costs to run. As network difficulty rises or BTC price falls, that margin shrinks, so it's wise to recalculate frequently.
How to use
Suppose you run an Antminer S19 with a hash rate of 110 TH/s, consuming 3,250 W of power. Your electricity costs $0.08/kWh and BTC is priced at $65,000. Revenue = 110 × 0.00000006 × 65,000 = $0.429/day Electricity = 3,250 × 24 × 0.08 / 1,000 = $6.24/day Daily Profit = $0.429 − $6.24 = −$5.81/day At these numbers, the miner runs at a loss. You would need either cheaper electricity, a higher BTC price, or a more efficient machine to break even.
Frequently asked questions
How does electricity cost affect Bitcoin mining profitability?
Electricity is typically the single largest operating expense in Bitcoin mining. Even a small increase in your rate per kWh can turn a profitable operation into a loss. For example, moving from $0.05/kWh to $0.10/kWh can double your daily electricity bill without changing your revenue at all. Miners in regions with cheap hydroelectric or wind power have a significant structural advantage. Always input your actual blended rate, including any demand charges, for an accurate result.
What hash rate do I need to profitably mine Bitcoin at home?
Home profitability depends on your electricity cost more than raw hash rate. With residential electricity averaging $0.12–$0.15/kWh in many countries, even top-tier ASICs like the S19 XP (140 TH/s) often operate near breakeven or at a loss. At $0.05/kWh, the same miner can generate meaningful daily profit. Use this calculator with your exact electricity rate and current BTC price to find the minimum hash rate that covers costs. Most hobbyist miners find cloud mining or simply buying BTC more cost-effective.
Why does Bitcoin network difficulty affect my mining earnings?
Network difficulty adjusts roughly every two weeks to ensure one block is found every ~10 minutes across all miners combined. When more miners join the network, difficulty rises and each individual miner earns a smaller share of the block reward. The constant in this calculator (0.00000006 BTC per TH/s per day) is an approximation based on recent difficulty levels. As difficulty increases, your actual daily BTC earnings will fall even if your hash rate stays constant. Monitoring difficulty trends alongside BTC price is essential for ongoing profitability assessment.
