Formula Used
Total hashrate = Hashrate per GPU × Number of GPUs.
Effective hashrate = Total hashrate × (1 − Stale share ÷ 100).
Daily XMR before pool fee = Effective hashrate × 86,400 × Block reward ÷ Network difficulty.
Daily XMR after pool fee = Daily XMR before pool fee × (1 − Pool fee ÷ 100).
Power cost per day = ((GPU watts × GPU count + System watts) ÷ 1000) × 24 × Electricity rate.
Net profit per day = Daily XMR after pool fee × XMR price − Power cost − Other daily cost.
Break-even days = Hardware cost ÷ Net daily profit.

GPU Mining Overview
A Monero mining calculator helps you compare reward, power, and cost before running a rig. Monero uses the RandomX mining method. It favors general processors, so many GPUs earn less than expected. Still, some users test graphics cards, rented rigs, or mixed systems. This calculator supports those checks with clear inputs.
What The Inputs Mean
Hashrate is the speed of your card or rig. Enter the measured rate, not an advertised rate. GPU count multiplies that speed. Power use combines card draw and extra system draw. Electricity price turns watts into daily cost. Pool fee and stale share reduce usable rewards. Network difficulty shows how hard a block is to find. XMR price converts coins into money.
Why Estimates Change
Mining income is never fixed. Difficulty changes as more or fewer miners join. Coin price moves all day. Pool luck can also change short term payouts. Hardware heat may reduce performance. Drivers, memory settings, and power limits also matter. For this reason, results should be treated as planning estimates, not guaranteed income.
Profit And Payback
The calculator estimates daily XMR first. It then subtracts pool fees, electricity, and other daily costs. Net profit can be multiplied by month, year, or a custom horizon. Hardware payback shows how many days are needed to recover rig cost. If daily net profit is zero or negative, payback is not available. That is useful warning.
Good Ways To Use It
Measure real wall power when possible. Use your pool dashboard for hashrate. Update the XMR price often. Try several difficulty values. Compare power limits against profit. A lower hashrate can still be better when it saves enough energy. Save the CSV or PDF report after each test. Then compare setups with simple records.
Important Limits
This page does not contact a live network feed. You control every assumption. That design makes old reports easier to repeat. It also protects the calculator from stale remote data. Use current pool, exchange, and difficulty numbers when accuracy matters. GPU mining may be used for experiments, but many Monero miners prefer efficient CPUs.
Keep notes for each driver change. Small tuning changes can move power cost faster than coin output. Review results before scaling rigs.
FAQs
Is GPU mining good for Monero?
Monero uses RandomX, which favors CPUs. GPUs can still be modeled here for testing, learning, rented hashpower, or mixed rigs. Always compare profit against power cost.
What is network difficulty?
Network difficulty estimates how many hashes are needed to find a block. A higher value lowers your expected coin output when your hashrate stays the same.
Why should I enter stale share?
Stale or rejected shares do not earn full rewards. Entering that percent gives a more realistic hashrate and lowers the estimated daily XMR.
How is electricity cost calculated?
The calculator adds GPU watts and system watts. It converts that total into kilowatt-hours per day, then multiplies by your electricity rate.
What does pool fee change?
Pool fee reduces the mining reward after estimated coins are calculated. A lower fee can improve profit, but reliability and payout rules also matter.
What is break-even time?
Break-even time shows how many profitable days are needed to recover hardware cost. It is only shown when daily net profit is positive.
Does this calculator use live XMR price?
No. Enter the current price yourself. This keeps the page simple and lets you test different market conditions without remote data.
What if the net profit is negative?
A negative result means power, fees, and extra costs are greater than estimated revenue. Try lower power settings, better rates, or updated price assumptions.
