Advanced GPU Hashrate Calculator
Formula Used
Total hashrate: GPU count × hashrate per GPU.
Total power: GPU power + system power + cooling power.
Network share: rig hashrate ÷ network hashrate.
Mining factor: uptime × pool factor × dev fee factor × stale factor.
Daily ETH: network share × daily network reward × mining factor.
Electricity cost: total watts × 24 ÷ 1000 × power rate.
Net profit: gross revenue − exchange fee − electricity cost − other cost.
How To Use This Calculator
Enter the number of graphics cards in your rig. Add the hashrate for one card in MH/s. Then enter the power draw for each card.
Add system, riser, cooling, and other power loads. Enter pool fee, dev fee, reject rate, and uptime. These values reduce effective rewards.
Add network hashrate, daily reward, coin price, electricity rate, and hardware cost. Press the calculate button. Review profit, efficiency, payback, and export the report.

GPU Hashrate Planning Guide
Why Hashrate Matters
GPU hashrate shows how many mining attempts your rig can make each second. A higher number improves your share of network work. It does not guarantee profit alone. Power use, fees, downtime, reject rate, and coin price can change the final result. This calculator combines those values in one place.
Build A Complete Rig Estimate
A good estimate starts with real card data. Enter the number of GPUs first. Then add the tuned hashrate for one card. Use measured wall power when possible. Software readings can miss risers, fans, motherboard draw, and power supply losses. Add system power and cooling power to make the result more practical.
Understand Reward Inputs
The reward section uses network share. Your rig hashrate is compared with the total network hashrate. That share is multiplied by daily network reward. This method is useful for historical Ethereum proof-of-work records and Ethash-style planning. Current Ethereum staking rewards are not calculated with GPU hashrate.
Account For Losses
Mining income is reduced by common losses. Pool fees remove a small part of rewards. Dev fees may apply when mining software charges for use. Stale or rejected shares also lower paid work. Uptime reflects restarts, heat issues, internet drops, and maintenance windows. Small percentages can become large over a month.
Power And Profit Review
Electricity is often the biggest cost. The calculator converts watts into daily kilowatt hours. It then multiplies that value by your local power price. Net profit subtracts power, exchange fees, and other daily costs. The break even power rate shows the highest electricity rate that still covers operating costs.
Use Results For Decisions
Use the efficiency value to compare cards. More MH/s per watt means better power performance. Use payback days to judge hardware risk. A short payback is usually safer than a long one. Export the CSV or PDF report when you need records for audits, testing, planning, or client comparisons.
FAQs
What does GPU hashrate mean?
GPU hashrate is the mining speed of a graphics card. It shows how many hash attempts the card can perform each second. This calculator uses MH/s for each GPU.
Can this calculate current Ethereum mining profit?
This tool is best for historical Ethereum proof-of-work records or Ethash-style planning. Current Ethereum mainnet rewards are not based on GPU mining hashrate.
Why is network hashrate needed?
Network hashrate shows the total mining power competing for rewards. Your rig share equals your hashrate divided by the network hashrate. That share estimates expected rewards.
What is stale or reject rate?
Stale or rejected shares are submitted mining shares that do not earn normal credit. They may happen because of latency, unstable tuning, heat, or pool issues.
How is electricity cost calculated?
The calculator multiplies total watts by 24 hours, divides by 1000, then multiplies by your electricity rate. This gives the daily energy cost.
What is mining efficiency?
Mining efficiency compares hashrate with power use. This page shows MH/s per watt and watts per MH/s. Better efficiency usually means lower operating cost.
Why include system and cooling power?
GPUs are not the only power draw. Motherboards, CPUs, risers, fans, and cooling devices also use electricity. Adding them gives a more realistic profit estimate.
What does payback period mean?
Payback period estimates how many profitable days are needed to recover hardware cost. It is not guaranteed because coin price, rewards, and difficulty can change.
