What is the best Monero mining profitability calculator?

For most beginners, WhatToMine’s Monero calculator is a good starting point. CoinWarz’s Monero calculator is a useful second opinion, but neither can promise what you will earn. The best estimate comes from entering your own measured mining speed and electricity use—not relying on preset hardware figures.

Why start with WhatToMine?

WhatToMine is useful for a first estimate because it brings together the main pieces of mining profitability: mining speed, power use, electricity price, and changing network conditions.

Make sure you use its Monero-specific calculator, not a general mining profitability list. Monero uses RandomX, a mining method designed to favor CPUs—the main processors in computers. Figures for mining other coins with graphics cards will not tell you much about your likely Monero earnings.

CoinWarz offers another Monero calculation you can compare against. I would use it as a cross-check rather than assume either service is always more accurate.

Before trusting either result, check that the calculator is using recent network data and current Monero mining rewards. A familiar name does not make an outdated calculation reliable.

The inputs matter more than the brand

Even a well-designed calculator gives a poor answer if you feed it guessed numbers. Enter:

• Your measured hashrate. This is your mining speed, usually shown in hashes per second, or H/s. A hash is one attempt at solving the mining puzzle.
• Your power use. Ideally, measure electricity drawn from the wall while mining. Your processor’s advertised power rating is not a measurement of your whole computer.
• Your electricity rate. Use the price per kilowatt-hour, or kWh, from your bill, including usage-based charges.
• Your mining hours. A 24-hour estimate will overstate your earnings if you mine for only a few hours.
• Your fees. Include mining pool, software, or service fees where applicable. A pool combines miners’ work and shares rewards.

For a computer you would otherwise leave on, you can compare the extra electricity caused by mining. If you run it specifically to mine, count its full power use.

For browser mining, use browser measurements

This is especially important if you mine through your web browser: do not enter a speed taken from a desktop mining benchmark. A benchmark is a performance test, and dedicated mining software can perform very differently from browser-based software.

Measure the speed you actually get in your browser after it settles. Watch for heat, reduced speed, and pauses when a tab is inactive. Your computer may slow itself down to avoid overheating.

Also check how your browser-mining service calculates payouts. A network calculator estimates the value of mining work; it may not reflect the service’s fees, reward rules, or minimum withdrawal amount. A displayed balance is not necessarily money you can withdraw today.

Read the result as a snapshot

Monero targets roughly one block every two minutes, with a base reward of 0.6 XMR per block. Mining difficulty—the measure of how hard it is to earn rewards—adjusts every block.

That means estimates change as competition and XMR’s price change. Compare both estimated XMR earned and profit after electricity. Hardware costs and wear may still be outside the displayed profit.

Avoid calculators or services promising guaranteed daily returns.

The bottom line

Start with WhatToMine and cross-check with CoinWarz. For browser mining, your actual browser speed, measured electricity use, and service payout rules matter more than which calculator you choose.
