Bitcoin Mining Profitability Calculator - Electricity Cost and ROI

Bitcoin Mining Profitability

Mining profitability depends on your share of total network hash rate, block rewards, electricity cost, and hardware efficiency. Daily BTC earned is estimated as:

$$\text{Daily BTC} = \frac{H_{\mathrm{miner}}}{H_{\mathrm{network}}} \times 144 \times 3.125 \times (1 - f)$$

where $H_{\mathrm{miner}}$ is your hash rate, $H_{\mathrm{network}}$ is total network hash rate, 144 is blocks per day, 3.125 is the post-2024 halving block reward, and $f$ is the pool fee fraction.

Electricity Cost

Daily electricity cost equals power draw in kW multiplied by 24 hours and your local rate per kWh. Net profit is revenue minus electricity cost. Efficiency is measured in J/TH (joules per terahash): lower values mean better hardware.

Break-Even Analysis

Break-even electricity price is the maximum $/kWh where revenue equals power cost. Break-even BTC price is the minimum BTC price needed to cover electricity at your current hash rate share.

Frequently Asked Questions

What block reward does this calculator use?

3.125 BTC per block, reflecting the April 2024 halving. The next halving is expected around 2028.

What is J/TH and why does it matter?

J/TH measures energy per terahash of computation. Lower J/TH means more efficient hardware and lower electricity cost per BTC mined.

How is network difficulty handled?

The 12-month projection applies a customizable monthly difficulty growth rate that reduces your share of rewards over time as the network grows.

Does this include transaction fees?

No. This estimate uses block subsidy only. Transaction fees add variable extra revenue not modeled here.

What electricity rate is profitable for mining?

Modern ASIC miners typically need rates below $0.06/kWh to stay profitable after the 2024 halving, though BTC price and hardware efficiency also matter. Use the break-even electricity field for your specific setup.
