Is mining Monero on a Raspberry Pi profitable?

Mining Monero on a Raspberry Pi is usually not profitable once you count electricity, cooling, and the cost of the Pi itself. If you already own one, it can be a fun, low-cost way to learn, but you should not expect meaningful income—especially from mining in a web browser.

Why a Raspberry Pi earns so little

Monero uses RandomX, a mining method that asks your processor to do work to help secure the network. Your reward depends partly on your hashrate: how many mining calculations your device completes each second.

RandomX favors general-purpose processors, but that does not mean every processor mines efficiently. Raspberry Pis have relatively small processors and limited high-speed memory compared with desktop computers.

For efficient mining, RandomX needs roughly 2 MB of L3 cache, a small pool of very fast processor memory, per mining thread. A thread is one stream of work. Common Pi models lack that amount of L3 cache, which limits performance.

Memory capacity also matters:

• RandomX fast mode uses a dataset of about 2,080 MB, plus working memory and space for your operating system.
• Its light mode uses a smaller 256 MB cache, but mining is substantially slower.
• Buying a Pi with more memory can help it fit the workload, but extra memory alone does not make its processor fast.

Low electricity use is not enough

A Pi uses little power, which sounds promising. The problem is that it also produces very little mining work. What matters is how much work you get for each watt, not simply whether the device uses fewer watts than a desktop.

Calculate your daily electricity cost like this:

Daily electricity cost = watts ÷ 1,000 × 24 × your price per kilowatt-hour

For example, if your Pi and cooling together draw 10 watts, they use 0.24 kilowatt-hours per day. At an illustrative electricity price of $0.20 per kilowatt-hour, that costs $0.048 a day. That is an example, not a measured figure for your setup.

Measure power at the wall if possible. Include the fan and power supply losses. Then subtract that cost from estimated mining revenue. Also consider whether you need to buy a Pi, power supply, memory card, or cooler. Small operating gains may never repay those purchases.

Browser mining makes the case weaker

Mining in a browser adds another limitation. Browser software generally cannot use your Pi’s hardware as effectively as a well-configured native miner—a program installed directly on the device.

A site may also take a fee, pause work in background tabs, or impose a minimum withdrawal amount. With a Pi’s small earnings, reaching that minimum could take a long time.

Before you run anything continuously, check:

• What work the site actually performs and how it calculates rewards.
• All fees and withdrawal requirements.
• Whether sustained load causes overheating or automatic processor slowdowns.
• Whether you can verify payouts rather than relying on advertised returns.

Never pay an “activation” or “unlock” fee to release supposed mining earnings.

The bottom line

Use a Raspberry Pi for Monero mining if your goal is learning, not dependable profit. Test your actual hashrate and wall power, then enter them into a live Monero mining calculator; prices and network competition change. If the estimate barely covers electricity, hardware costs and payout restrictions can still leave you losing money.
