Formula Used

Network hash rate = difficulty × 2³² ÷ block time.

Expected coins per day = effective rig hash rate ÷ network hash rate × blocks per day × block reward.

Effective rig hash rate = total GPU hash rate × uptime × accepted share rate.

Power cost per day = total watts ÷ 1000 × 24 × uptime × electricity cost.

Net profit = gross revenue − exchange fee − power cost − other daily costs.

Payback days = hardware cost ÷ daily net profit.

Why Use This GPU Mining Calculator?

GPU mining looks simple, but profit changes quickly. A rig can earn coins, yet power, fees, rejected shares, and market price can remove the margin. This calculator gives a structured estimate before you buy hardware or run a card all day. It is useful for hobby miners, lab tests, and small farm planning.

Inputs That Shape Mining Profit

The most important input is effective hash rate. More cards usually add more hash power, but they also add power demand and heat. Electricity cost is the next major factor. A low tariff can make a weak rig viable. A high tariff can turn strong hardware into a loss. Pool fee, rejected shares, uptime, and exchange fee reduce the final value.

Difficulty, Price, and Risk

Network difficulty shows how hard it is to find a block. When difficulty rises, each hash earns less. Coin price controls the money value of each reward. The tool lets you add monthly difficulty growth and a monthly price trend. These settings are estimates only. They help you test optimistic, neutral, and cautious cases.

Planning a Rig Budget

Hardware cost matters because mining profit is not complete until the rig pays back. The payback value divides hardware cost by daily net profit. A short payback can still be risky if coin price falls. A long payback may be acceptable for learning, heating reuse, or hardware resale. Always include risers, frame, cables, fans, and power supplies.

Reading the Result

The result shows coins mined, gross revenue, power cost, fees, net profit, margin, and payback. A positive daily net means the selected assumptions are profitable. A negative value means the rig loses money under those assumptions. The period projection uses your trend settings. Save the CSV for spreadsheets, or export the PDF for a quick report.

Smart Mining Notes

Check real pool statistics before relying on any estimate. Measure wall power with a meter. Tune cards for efficiency, not only hash rate. Keep spare budget for repairs. Mining can be noisy, hot, and uncertain. Use this tool as a planning guide, not as a guaranteed income promise. Review tax rules, local energy limits, and warranty terms. Scale your operation safely today after review.

FAQs

1. What does this GPU mining calculator estimate?

It estimates coins mined, power cost, gross revenue, net profit, profit margin, and hardware payback from your rig settings and network assumptions.

2. Why is my mining profit negative?

Profit becomes negative when power cost, fees, and other costs are greater than mining revenue. High electricity prices often cause this result.

3. What is network difficulty?

Network difficulty measures how hard it is to find a valid block. Higher difficulty reduces the expected coins earned by the same hash rate.

4. Should I use wall power or GPU power?

Wall power is better. It includes GPUs, motherboard, fans, power supply losses, and other system load. It gives a more realistic cost estimate.

5. What is rejected share percentage?

Rejected shares are submitted mining shares that the pool does not accept. They reduce effective hash rate and lower expected earnings.

6. Why include monthly difficulty change?

Difficulty can rise or fall over time. This option lets the projection adjust future coin output instead of assuming one fixed network condition.

7. Is the payback estimate guaranteed?

No. Payback depends on coin price, difficulty, hardware uptime, electricity cost, and repairs. Use it as a planning estimate only.

8. Can I export my result?

Yes. After calculation, use the CSV button for spreadsheet data or the PDF button for a simple printable report.
