Bitcoin Mining Calculator: Break-even, Electricity Cost & Profit

Quick answer: Whether Bitcoin mining is profitable comes down to three variables — your hashrate (TH/s), rig power draw (W) and electricity price ($/kWh). The core formula: daily profit = BTC mined × price − daily power cost. Enter these three in the Bitcoin Mining Calculator to get daily/monthly net profit and break-even time.

Calculating break-even

Break-even = hardware cost ÷ daily net profit. Example: a $2,000 rig earning $3/day net breaks even in about 667 days. But that number is dynamic — network difficulty adjusts every two weeks and trends up, so the same hashrate mines fewer coins each month; a halving cuts the block reward in half instantly. Real break-even is usually slower than a static estimate.

Electricity is destiny

Mining is fundamentally energy arbitrage. The key metric is the shutdown price — the coin price at which power cost equals mining output; below it, you mine at a loss. On the same rig, $0.04 vs $0.08/kWh can be the line between profit and loss. Residential rates ($0.10+/kWh in most regions) are uneconomic at current difficulty — which is why farms sit near cheap hydro and wind.

Costs the calculator misses

Rigs depreciate and fail, hosting carries management fees, and static calculators usually exclude these. Factor in price risk too — you're estimating a year of revenue at today's price. The rational approach: use the calculator to find the break-even electricity price and coin price, then check them against your real conditions, rather than fixating on an optimistic "daily profit" figure.

To compare different rigs or power rates, just adjust the parameters in the mining calculator.
