Formula Used
Total miner hashrate = number of GPUs × hashrate per GPU.
Blocks per day = 86,400 ÷ block time in seconds.
Gross coins per day = miner hashrate ÷ network hashrate × blocks per day × block reward × uptime rate.
Net coins per day = gross coins per day × (1 − pool fee − dev fee).
Daily revenue = net coins per day × coin price.
Daily electricity cost = total watts ÷ 1000 × 24 × electricity cost per kWh.
Daily profit = daily revenue − daily electricity cost − daily maintenance cost.
ROI days = net hardware cost ÷ daily profit.

GPU Mining Profit Planning Guide
Why GPU Mining Needs Careful Math
GPU mining can look simple at first. A rig creates hashes.
The pool pays rewards. The coin price creates revenue.
Yet profit depends on many moving parts. Power cost can erase earnings.
Fees reduce rewards. Network hashrate changes your share.
Downtime also lowers your real return.
Understanding Mining Share
This calculator compares your rig hashrate with network hashrate.
That ratio estimates your share of daily block rewards.
A higher share means more expected coins. A larger network lowers your share.
This is why the same GPU rig may earn less later.
Difficulty and network growth often move together.
Power Cost Matters Most
Electricity is usually the largest operating cost.
Each GPU uses power while hashing. Risers, fans, motherboards, and power supplies add more load.
The calculator includes extra rig power for those parts.
It also converts watts into daily kilowatt hours.
This gives a clearer cost estimate.
Fees, Uptime, and Real Profit
Pool fees and miner fees reduce coins before sale.
Uptime reflects real operation. A rig may restart, overheat, or lose internet.
Using one hundred percent uptime can overstate profit.
A realistic value gives better planning.
Maintenance cost covers fans, cables, cleaning, and small repairs.
ROI and Risk
ROI days show how long profit needs to recover hardware cost.
The calculator subtracts expected resale value first.
This creates a practical net hardware cost.
A positive result still carries risk. Coin price can fall.
Network hashrate can rise. Hardware can fail.
Use this tool as an estimate, not a guarantee.
Frequently Asked Questions
1. What does this GPU mining calculator estimate?
It estimates coins, revenue, electricity cost, net profit, ROI time, and break-even coin price using your rig and network inputs.
2. Why do I need network hashrate?
Network hashrate shows total competition. Your rig earns a share based on its hashrate compared with the whole network.
3. Does this calculator include electricity cost?
Yes. It multiplies total rig watts by daily hours, then applies your electricity price per kilowatt hour.
4. Why is uptime included?
Mining rigs rarely run perfectly forever. Uptime accounts for restarts, internet loss, maintenance, heat issues, and pool connection problems.
5. What is break-even coin price?
It is the coin price needed to cover daily electricity and maintenance costs before counting hardware recovery.
6. Can this calculator predict exact mining income?
No. Mining income changes with price, blocks, luck, fees, difficulty, network hashrate, pool performance, and hardware stability.
7. Should I include extra rig power?
Yes. Add power used by fans, motherboard, CPU, risers, storage, and power supply losses for a better estimate.
8. Why subtract resale value from hardware cost?
Resale value reduces your real long-term capital risk. It helps estimate a more practical recovery target.
