How to Use This Calculator
Tab "Daily Profit"
Enter your miner's hashrate in TH/s, power consumption in watts, your electricity cost per kWh, the pool fee percentage, and the current coin reward rate per TH/s per day. The calculator shows daily revenue, daily electricity cost, and daily profit, plus monthly and annual projections.
Tab "Break-Even"
Enter your total hardware cost and the daily profit from Tab 1. The result shows how many days (and months) until your mining revenue covers the initial hardware investment.
Tab "ROI Timeline"
Enter your hardware cost, monthly profit, and expected hardware lifespan in months. The calculator shows total ROI percentage, annualized ROI, and net profit over the full lifespan of the equipment.
The Formulas
Daily Revenue = Hashrate (TH/s) × Reward Rate ($/TH/s/day) × (1 − Pool Fee %)
Daily electricity cost:
Daily Electricity = Power (W) / 1,000 × 24 hours × Electricity Rate ($/kWh)
Daily profit:
Daily Profit = Daily Revenue − Daily Electricity Cost
Break-even days:
Break-Even = Hardware Cost / Daily Profit
Total ROI:
Total ROI = (Total Profit − Hardware Cost) / Hardware Cost × 100
Annualized ROI:
Annualized ROI = (Total ROI / Lifespan Months) × 12
All calculations use the inputs you provide. Reward rate, network difficulty, and coin price change constantly — re-run calculations periodically for up-to-date estimates.
Worked Examples
Example 1 — Bitcoin ASIC daily profit: 100 TH/s, 3,250W, $0.08/kWh
A Bitcoin ASIC miner running at 100 TH/s with 3,250W power draw, $0.08/kWh electricity, 1% pool fee, and a reward rate of $0.12/TH/s/day.
After electricity and pool fees, this miner nets about $5.64 per day. Electricity accounts for more than half of gross revenue, making the electricity rate a critical factor in profitability.
Example 2 — Break-even analysis: $3,500 hardware
Using the daily profit from Example 1 ($5.76/day rounded), how long to recoup the $3,500 hardware investment?
At $5.76/day net profit, this miner takes about 20 months to pay for itself. If difficulty rises or coin price drops, break-even extends further. If price rises, it shortens.
Example 3 — ROI over 24-month lifespan
Assuming the hardware lasts 24 months and generates $172.80/month in profit, what is the total return on investment?
Over its full 24-month life, this ASIC generates an 18.5% total return, or roughly 9.2% annualized. The hardware pays for itself after 20 months and earns $647 in net profit over the remaining 4 months.
Understanding Mining Profitability
Cryptocurrency mining profitability depends on four main factors: hashrate (your computational power), electricity cost (your biggest ongoing expense), network difficulty (how hard it is to find a block), and coin price (how much each mined coin is worth in fiat).
The reward rate per TH/s per day captures both difficulty and price in a single number. As difficulty rises or price drops, this rate decreases. As difficulty falls or price rises, the rate increases. Most mining pool dashboards display this figure, or you can calculate it from current block rewards and network hashrate.
Pool fees typically range from 0.5% to 3%. Solo mining avoids pool fees but introduces high variance — you might mine nothing for months. Most miners join pools for consistent, predictable payouts.
Key Factors That Change Profitability
- Electricity cost — The single biggest variable. Miners in regions with cheap hydro or solar power ($0.03–$0.05/kWh) have a huge advantage over those paying residential rates ($0.10–$0.30/kWh).
- Network difficulty — For Bitcoin, difficulty adjusts every ~2,016 blocks (~2 weeks). As more miners join the network, difficulty rises and each TH/s earns less.
- Coin price — A doubling in coin price roughly doubles your revenue (at constant difficulty). But price can also halve, wiping out profits.
- Hardware efficiency — Newer ASIC models produce more TH/s per watt. The joules-per-terahash (J/TH) metric lets you compare miner efficiency directly.
- Block reward halvings — Bitcoin halves its block reward roughly every 4 years. After each halving, revenue per TH/s drops ~50% unless coin price compensates.
Frequently Asked Questions
What hashrate unit should I use?
This calculator uses TH/s (terahashes per second), which is standard for Bitcoin ASIC miners. 1 TH/s = 1,000 GH/s = 1,000,000 MH/s. If your miner reports in GH/s, divide by 1,000 to convert.
Where do I find the current reward rate?
Mining pool dashboards typically show estimated daily earnings per TH/s. You can also find this on sites like WhatToMine, CryptoCompare, or your pool's statistics page. For Bitcoin in early 2026, the rate is roughly $0.08–$0.15 per TH/s per day, depending on price and difficulty.
Should I include cooling costs in electricity?
Yes. If you run additional cooling (fans, AC), add that power consumption to your miner's wattage, or increase your electricity rate to account for the overhead. In hot climates, cooling can add 10–30% to electricity costs.
Is GPU mining still profitable?
After Ethereum's move to proof-of-stake in 2022, GPU mining profitability dropped significantly. Some altcoins can still be mined with GPUs, but margins are thin. This calculator works for GPU mining too — just enter your GPU rig's hashrate (converted to TH/s), power draw, and the relevant coin's reward rate.
Does this calculator account for taxes?
No. Mining income is taxable in most jurisdictions. The profit figures shown are pre-tax. Consult a tax professional for your specific situation. In the US, mined coins are taxed as ordinary income at fair market value when received.
