How do I use a Monero mining calculator step by step?

To use a Monero mining calculator, enter your mining speed, electricity use, power price, and any fees, then compare the estimated income with your costs. Treat the result as a forecast, not a promise—especially if you mine in a browser, where performance and payout rules can differ from dedicated mining software.

1. Measure your actual mining speed

Choose a calculator that supports Monero’s current mining method, RandomX. Avoid old calculators built for CryptoNight, the method Monero replaced in November 2019.

Your main input is hashrate: how many mining calculations your device performs each second.

• Run your miner long enough for its speed to settle.
• Record a typical average, rather than its highest reading.
• Note the unit. 1 kilohash per second (kH/s) equals 1,000 hashes per second (H/s).

For browser mining, measure the speed in the browser you actually plan to use. Keep your usual tabs and mining settings active. A desktop processor benchmark may greatly overstate what your browser delivers.

If the service does not clearly explain what it mines or how it converts work into XMR payments, a standard Monero calculator may not match its payouts.

2. Enter electricity use and your power price

Find the calculator’s power field, usually measured in watts (W). A plug-in wall meter gives a more useful measurement than your processor’s advertised power rating.

Which number should you enter?

• If you turn the computer on only to mine, use its total power draw while mining.
• If it would already be running, compare power use with and without mining. The difference estimates the extra electricity mining uses.

Next, enter your electricity rate per kilowatt-hour (kWh), the unit your electricity provider bills you for. Use the applicable per-unit cost from your bill, including usage-based charges.

For example, an extra 50 watts running for eight hours uses:

50 ÷ 1,000 × 8 = 0.4 kWh

Multiply that by your own electricity rate to calculate the daily electricity cost.

3. Set fees, running time, and network inputs

Enter any mining pool fee. A pool combines miners’ work and shares rewards among them. Also check for separate browser-service fees or withdrawal charges. Do not count the same fee twice.

Set your expected hours per day. If the calculator assumes 24-hour operation, scale its daily estimate to your actual running time. Eight hours is roughly one-third of a full day, assuming steady performance.

Use current network data and XMR prices from a live calculator or explorer, a tool that displays blockchain activity. Network difficulty measures how hard it is to mine a block; Monero adjusts it every block.

If manual reward inputs are required, Monero’s base reward is 0.6 XMR per block, with blocks averaging about two minutes. Transaction fees can add to that reward.

4. Read the result and test it

Check these outputs separately:

• Estimated XMR: the coins your work might earn.
• Revenue: those coins’ estimated value before costs.
• Profit: revenue minus the costs included in the calculator.

Check whether hardware costs and withdrawal fees are excluded. Also compare estimated earnings with the service’s minimum payout: earning a small balance does not mean you can withdraw it immediately.

Run a second estimate with lower hashrate or fewer hours. Then compare the forecast with your actual credited earnings over several days.

The bottom line

Start with measured performance and your own electricity price. Use the calculator to test whether mining looks worthwhile, then verify its estimate against real costs and payouts.
