About this calculator
Bitcoin mining profitability depends on two competing forces: revenue earned from hashing and costs paid for electricity. Your expected share of the coins mined each day is your hash rate divided by the whole network's: about 144 blocks a day × 3.125 BTC block subsidy (since the April 2024 halving) = 450 BTC. Daily Profit = (hashRate ÷ (networkHashrate × 1,000,000) × 450 × btcPrice) − (powerConsumption × 24 × electricityCost ÷ 1,000). Hash rate is in TH/s and network hash rate in EH/s (1 EH/s = 1,000,000 TH/s); the default network figure is about 950 EH/s (September 2026), so update it from a live source. The electricity term converts watts to kWh per day. Transaction fees (usually a few percent of miner revenue), pool fees (1–3%) and hardware costs are not included. As network difficulty rises or BTC price falls, the margin shrinks, so recalculate frequently; the next halving (around 2028) cuts the subsidy to 1.5625 BTC.
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, BTC is priced at $65,000 and the network runs at 950 EH/s. Revenue = 110 ÷ 950,000,000 × 450 × 65,000 = $3.39/day Electricity = 3,250 × 24 × 0.08 / 1,000 = $6.24/day Daily Profit = $3.39 − $6.24 = −$2.85/day At these numbers, the miner runs at a loss. You would need cheaper electricity (below about $0.043/kWh), 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. This calculator uses your share of the network hash rate, which tracks difficulty: when the network grows from 950 to 1,100 EH/s, your daily BTC earnings fall by about 14% even if your hash rate stays constant. Enter the current network hash rate for an up-to-date estimate. Monitoring difficulty trends alongside BTC price is essential for ongoing profitability assessment.
