How much does it cost to start mining Monero?

You can start mining Monero with no extra hardware spending if you already own a suitable computer, but running it still uses electricity and adds wear. Buying a dedicated setup can cost hundreds of dollars or more, so your cheapest way to begin is usually a small test on a computer you already have.

What you need to pay for upfront

Monero mining uses your computer’s processor, or CPU, to help check transactions and secure the network. In return, you have a chance to earn XMR, Monero’s currency.

Your starting costs depend mostly on what you already own:

• An existing desktop: Your extra hardware cost may be $0. You still need to account for electricity.
• An existing laptop: You can experiment, but heat, fan noise, and limited cooling make it less suitable for sustained mining.
• A dedicated computer: Budget for the whole system, not just the processor. That includes memory, storage, a power supply, a motherboard, and cooling.

You do not need an expensive graphics card to mine Monero. Its mining method, called RandomX, favors CPUs. More expensive equipment does not automatically mean a better return.

A Monero wallet, which lets you receive and control your XMR, can be free. Reputable mining software is also available for free. You should not need to buy coins or pay an “activation fee” to start.

Your main running cost is electricity

Check your electricity bill for the price per kilowatt-hour, or kWh. This is the unit your provider uses to charge for energy.

Use this calculation:

Daily electricity cost = wall power in watts ÷ 1,000 × hours running × price per kWh

For example, if your whole computer draws 150 watts while mining and electricity costs $0.20 per kWh:

• Running for 24 hours uses 3.6 kWh.
• That costs $0.72 per day.
• Over 30 days, that costs $21.60.

These are example costs, not expected earnings. A plug-in electricity meter can measure your actual wall power. The processor’s advertised power rating alone does not tell you what the whole computer uses.

If your computer would already be running, you can measure the extra electricity mining adds. If you switch it on only to mine, count its full usage.

Other costs that can reduce your earnings

A mining pool combines your mining work with other people’s work so payouts can be more regular. Some pools take a percentage of your rewards as a fee.

Also check for:

• Payout minimums: You may need to earn a certain amount before receiving anything.
• Software or service fees: Some tools keep a share of your mining work or rewards.
• Cooling and wear: Fans run harder, and extra room cooling can raise your electricity bill.

Browser mining may be easy to try, but it typically performs worse than dedicated mining software. Check what a site charges and how withdrawals work. A demand for a deposit to “unlock” earnings is a warning sign.

The bottom line

Start with equipment you own, set a small electricity budget, and measure your results before buying anything. Use your measured hashrate, meaning mining speed, and power use in a live profitability calculator. Compare expected earnings with electricity and fees; if you buy hardware, include its purchase cost too. Starting cheaply is possible, but making a profit is not guaranteed.
