Calculator Inputs
Example Data Table
| GPU Setup | GPU Count | Hash Rate Per GPU | Power Per GPU | Electricity Cost | Use Case |
|---|---|---|---|---|---|
| Small test rig | 2 | 45 MH/s | 110 W | 0.10 per kWh | Learning and testing |
| Mid range rig | 6 | 60 MH/s | 130 W | 0.12 per kWh | Home mining plan |
| Large rig | 12 | 95 MH/s | 210 W | 0.15 per kWh | Advanced cost review |
Formula Used
Total hash rate = GPU count × hash rate per GPU.
Effective hash rate = total hash rate × uptime factor × accepted share factor.
Estimated coins per day = effective hash rate × 86400 × block reward ÷ difficulty ÷ 2^32.
Daily revenue = estimated coins per day × coin price.
Daily electricity cost = total watts × 24 × uptime factor ÷ 1000 × electricity cost.
Daily net profit = revenue − fees − electricity − maintenance − tax estimate.
Breakeven days = hardware cost ÷ daily net profit.
How To Use This Calculator
Enter the number of GPUs in your rig. Add the hash rate for one GPU. Select the correct hash rate unit.
Enter power draw for each card. Add extra system power for fans, motherboard, risers, and power supply losses.
Enter electricity price, coin price, network difficulty, block reward, and block time. Add pool, software, and exchange fees.
Use uptime and rejected shares to make the estimate more realistic. Enter hardware cost to calculate ROI and breakeven time.
Press the calculate button. Review the result section above the form. Export CSV or PDF reports when needed.
GPU Mining Profitability Planning
Core Profit Factors
GPU mining can look simple at first. A card creates hash rate. The rig uses power. The mined coin has a market price. Real profit comes from connecting all these values. This calculator helps you test those parts together. It estimates coin output from hash rate, difficulty, block reward, and block time. It then subtracts electricity, pool fees, software fees, exchange fees, maintenance, and taxes.
Why Each Input Matters
Hash rate shows how much work your cards perform. More hash rate can increase rewards. Power draw shows the energy used by the whole rig. This should include cards, motherboard, fans, risers, and power supply loss. Electricity price is often the largest running cost. A small rate change can turn profit into loss. Uptime also matters. Rigs rarely run perfectly every day. Heat, driver issues, rejected shares, and pool downtime reduce income.
Reading The Results
The result section shows daily, monthly, and yearly revenue. It also shows costs and net profit. Coin per day is an estimate, not a promise. Network difficulty changes often. Coin prices can move quickly. Use the return on investment value as a planning guide. It is not a guaranteed payback date. A positive result today can become negative later.
Better Mining Decisions
Test several cases before buying hardware. Try a conservative coin price. Raise electricity cost to include taxes and delivery charges. Lower uptime if the rig is placed in a warm room. Add realistic maintenance and hosting charges. Enter hardware cost to see breakeven time. Compare different GPUs by using the same assumptions for each card. This keeps comparisons fair.
Risk And Practical Use
Mining profitability depends on market, network, and hardware risk. Difficulty can rise when more miners join. Rewards can fall after protocol changes. Power supplies, fans, and cables also need safe sizing. Good airflow protects cards and reduces shutdowns. Keep records of results over time. Exporting CSV and PDF reports can help track assumptions. Update the calculator whenever price, difficulty, or power cost changes. Careful planning helps you avoid costly surprises. Use measured wattage when possible. Wall readings are better than software estimates. Save each scenario before changing major assumptions. This makes later reviews easier and more reliable.
FAQs
What does this GPU mining calculator estimate?
It estimates coins mined, revenue, electricity cost, fees, tax estimate, net profit, ROI, breakeven time, and cost per mined coin.
Why is network difficulty important?
Network difficulty affects how often your hash rate earns rewards. Higher difficulty usually lowers estimated coin output for the same hardware.
Should I enter power for one GPU or all GPUs?
Enter power for one GPU in the GPU power field. The calculator multiplies it by the number of cards automatically.
What should system power include?
System power should include motherboard, CPU, risers, fans, drives, controllers, and power supply losses not counted in GPU power.
Why does uptime change the result?
Uptime reduces both mining time and electricity use. Lower uptime means fewer accepted hashes, fewer coins, and lower operating cost.
What are rejected shares?
Rejected shares are mining submissions not accepted by the pool. They reduce effective hash rate and lower estimated earnings.
Is the breakeven result guaranteed?
No. Breakeven is only an estimate. Coin price, network difficulty, rewards, fees, hardware faults, and electricity rates can change quickly.
Can I compare different GPU rigs?
Yes. Enter each rig with the same coin, difficulty, fee, and electricity assumptions. Then compare net profit and ROI values.
