Calculate Bitcoin mining profitability based on hashrate, power consumption, and electricity costs.
Your miner's hashrate in terahashes per second
Power consumption of your mining hardware
Cost of electricity per kilowatt-hour
Mining pool fee percentage

Current Bitcoin price (defaults to $65,000)
Mining secures the Bitcoin network by solving complex mathematical problems. Miners are rewarded with newly created Bitcoin (block reward) plus transaction fees. It requires specialized hardware (ASICs) and significant electricity.
Your miner's processing speed measured in terahashes per second. Higher hashrate = more mining power = higher chances of earning rewards. Modern ASICs range from 50-150 TH/s.
Individual miners join pools to combine hashrate and share rewards proportionally. Pools charge 0.5-2% fees but provide steady, predictable income versus solo mining's lottery-like payouts.
Currently 3.125 BTC per block (after April 2024 halving). Block rewards halve approximately every 4 years, reducing miner income. Next halving: ~2028.
Adjusts every ~2 weeks to maintain 10-minute block times. As more miners join, difficulty increases, reducing individual earnings. Monitor difficulty trends.
The primary operational expense. Mining is profitable only when revenue exceeds power costs. Successful miners secure electricity rates under $0.08/kWh, ideally under $0.05/kWh.
Your miner's hashrate. Example: Antminer S19 Pro = 110 TH/s. Find this in your hardware specifications.
Watts used by your miner. Example: S19 Pro = 3250W. Check manufacturer specs or measure with a power meter.
Cost per kilowatt-hour ($/kWh). Check your utility bill. Industrial rates are typically $0.03-0.15/kWh.
Percentage charged by your mining pool. Typical range: 0.5-2%. Check your pool's fee structure.
Initial investment in mining equipment. Used to calculate break-even period. New ASICs: $2,000-10,000.
Current Bitcoin price. Defaults to $65,000 if not specified. Check live prices on exchanges.
Antminer S19 Pro: 110 TH/s, 3250W, electricity $0.10/kWh, pool fee 1%, hardware cost $5,000:
(Your Hashrate / Network Hashrate) × Block Reward × Blocks/Day
Example: (100 / 450,000,000) × 3.125 × 144 ≈ 0.0001 BTC/day
Daily Revenue × (Pool Fee % / 100)
Example: 0.0001 × (1 / 100) = 0.000001 BTC
Daily Revenue - Pool Fees
Then convert to USD: Revenue × BTC Price
(Watts / 1000) × 24 hours × $/kWh
Example: (3250 / 1000) × 24 × $0.10 = $7.80/day
Daily Revenue (USD) - Daily Power Cost
Monthly: Daily × 30 | Yearly: Daily × 365
Hardware Cost / Daily Profit

The #1 profitability factor. At $0.15/kWh most mining is unprofitable. Below $0.06/kWh enables good margins. Industrial rates or renewable energy sources are ideal.
Initial investment: $2,000-10,000 per ASIC. Used equipment is cheaper but less efficient. Factor in shipping, customs, PSUs, and cooling.
0.5-2% of revenue. Lower isn't always better—reliable payouts matter. Research pool reputation, payout methods (PPS, PPLNS), and uptime.
Cleaning, cooling, repairs. Expect 2-5% downtime. Dust buildup reduces efficiency. Budget for fan replacements and occasional repairs.
Directly impacts USD revenue. At $100K BTC, mining is ~50% more profitable than at $65K. Price volatility creates uncertainty in long-term projections.
Adjusts every ~2 weeks. More miners = higher difficulty = lower individual rewards. Can swing ±5-10% per adjustment. Monitor difficulty trends.
Measured in W/TH (watts per terahash). Modern ASICs: 20-30 W/TH. Older models: 40-60+ W/TH. Lower = better. Efficiency matters more than raw hashrate.
Block rewards halve every ~4 years. Next halving: ~2028. Reduces revenue by 50% overnight. Price often rises to compensate, but not guaranteed.
Research current ASICs: Antminer S19/S21 series, WhatsMiner M50/M60 series. Prioritize efficiency (W/TH) over raw hashrate. Buy from authorized dealers.
Contact local utility for industrial rates. Consider solar/wind if feasible. Target under $0.08/kWh, ideally $0.05/kWh or less. Location matters more than hardware.
ASICs are loud (70-80 dB) and hot (3-4 kW heat each). Needs: proper ventilation, noise insulation, stable internet, adequate electrical capacity, cooling system.
Research pools: Foundry, AntPool, F2Pool, ViaBTC. Compare fees (0.5-2%), payout methods, and minimum payouts. Solo mining is unrealistic for individuals.
Track: hashrate stability, temperature (keep under 75°C), power consumption, pool payouts. Use monitoring software. Clean filters monthly. Log downtime.
Mining rewards are taxable income when received. Track daily BTC earned and USD value. Selling BTC creates capital gains/losses. Consult a tax professional.
New miners underestimate power costs. A 3.25kW ASIC at $0.15/kWh costs $350+/month. Always calculate before buying hardware.
Used S9 miners (60+ W/TH) are nearly impossible to profit from. Efficiency matters more than initial cost. Buy current-gen hardware.
ASICs are LOUD (like a vacuum) and hot. Can't run in bedroom. Residential electricity rates often kill profits. Noise complaints from neighbors are common.
Overheating reduces lifespan and hashrate. Each ASIC outputs 3-4kW of heat. Needs active ventilation or AC. Don't stack units without airflow.
Many scam sites sell fake/nonexistent hardware. Buy only from verified sources: Bitmain, MicroBT authorized dealers. Too-good prices = scam.
Network difficulty typically rises, reducing your BTC earned over time. Today's profitability won't last. Build in margin for difficulty increases.
3.25kW ASIC needs 240V/15A circuit. Running multiple units requires electrical upgrade. Hire licensed electrician—don't DIY and cause fire hazards.
Mining income is taxable. Track every payout's USD value. Selling BTC = capital gains. Failure to report can result in penalties. Consult tax pro.
