How this miner profitability calculator works
This miner profitability calculator estimates your expected daily, monthly, and yearly mining profit based on your hashrate, network hashrate, block reward, coin price, power draw, and electricity rate. It is designed for proof-of-work mining setups such as Bitcoin ASIC mining, Litecoin mining, and other SHA-256 or Scrypt-style networks where rewards are tied to hashrate share.
The key idea is simple: your machine earns a percentage of total block rewards proportional to your share of network hashrate. From that gross revenue, we subtract pool fee and energy cost to estimate net profit.
Core formula behind mining profitability
1) Expected coins mined per day
- Blocks per day = 86,400 / (block time in seconds)
- Your share of network = miner hashrate / network hashrate
- Daily coins (gross) = share × blocks per day × block reward
- Daily coins (net) = gross × (1 − pool fee) × uptime factor
2) Revenue and costs
- Daily revenue (USD) = daily coins × coin price
- Daily energy use (kWh) = (watts / 1000) × 24 × uptime factor
- Daily electricity cost = daily kWh × electricity price
- Daily profit = daily revenue − daily electricity cost
Input guide for better accuracy
Hashrate inputs
Enter your miner hashrate exactly as specified by your model (for example, 140 TH/s for a modern ASIC). Network hashrate should come from a reliable blockchain explorer. If network hashrate is stale or inaccurate, your estimate can be off by a large margin.
Energy assumptions
Power consumption is one of the most important variables in any crypto mining calculator. Use measured wall power if possible, not marketing specs. Real-world numbers include PSU losses, fan curves, ambient temperature effects, and throttling under high heat.
Pool fee and uptime
Mining pool fee and uptime directly impact output. A 2% pool fee and 95% uptime can reduce effective returns more than most beginners expect. Uptime should reflect internet interruptions, thermal shutdowns, firmware crashes, and maintenance.
Example scenario
Suppose you run a 100 TH/s miner at 3000W, pay $0.12/kWh, and mine on a network with 600 EH/s hashrate, 3.125 block reward, and 10-minute block times. At a coin price of $65,000 and pool fee of 2%, you can use the calculator above to estimate:
- Expected daily coins
- Daily gross revenue in USD
- Daily energy expense
- Net daily, monthly, and annual profitability
- Break-even timeline if you enter hardware cost
What can change your results quickly
Coin price volatility
Mining economics are highly sensitive to market price. A 10% move in coin price can swing ROI from positive to negative in days. Always test conservative, base, and optimistic price assumptions.
Difficulty and network growth
Even if coin price stays flat, increasing network hashrate lowers your reward share. This is why “today’s profitability” is not guaranteed tomorrow. Difficulty adjustments and new hardware deployments constantly reshape expected returns.
Operational overhead
The calculator estimates core economics, but real mining businesses also pay for cooling, repairs, downtime, noise control, facility rent, and taxes. Build a margin of safety before purchasing expensive equipment.
ASIC vs GPU profitability considerations
- ASIC miners: Higher efficiency on specific algorithms, but less flexibility if the market shifts.
- GPU rigs: More algorithm flexibility, often lower efficiency for Bitcoin-style SHA-256 mining.
- Resale value: Depends on cycle timing, hardware condition, and regulation in your region.
- Noise and heat: Industrial ASIC setups often require purpose-built ventilation and power planning.
Risk management checklist for miners
- Model multiple electricity prices (off-peak and peak tariffs).
- Stress-test with lower coin prices and higher network hashrate.
- Track uptime and stale shares weekly.
- Keep firmware and security practices current.
- Plan liquidity for maintenance and replacement cycles.
Final thoughts
A mining profitability estimate is a planning tool, not a guarantee. Use this calculator frequently as market data changes, and revisit assumptions before scaling hardware purchases. Small improvements in efficiency, uptime, and power rate often make a bigger long-term difference than trying to time short-term price moves.
