How much XMR can I mine with a 10 kH/s CPU?
A CPU delivering a steady 10 kH/s can mine about 0.00108 XMR per day if Monero’s total network hashrate is 4 GH/s. That is a worked example, not a current earnings quote: your actual XMR depends on network competition, your mining time, and fees.
What 10 kH/s means for your earnings
Your hashrate is the number of mining calculations your CPU performs each second. At 10 kilohashes per second, or 10 kH/s, you are doing 10,000 calculations per second.
Mining rewards depend on your share of all that work. If the network produces 4 billion calculations per second—4 GH/s, or gigahashes per second—your CPU contributes:
- Your hashrate: 10,000 H/s
- Example network hashrate: 4,000,000,000 H/s
- Your share: 0.00025%
Monero targets one block roughly every two minutes. Each block pays a base reward of 0.6 XMR, plus transaction fees. That works out to roughly 432 XMR a day in base rewards across the whole network.
Your estimated daily and monthly XMR
You can estimate your share of those base rewards with:
Daily XMR ≈ your hashrate ÷ network hashrate × 432
For a CPU running continuously at 10 kH/s, these hypothetical network levels give:
- At 3 GH/s: about 0.00144 XMR/day, or 0.0432 XMR per 30 days
- At 4 GH/s: about 0.00108 XMR/day, or 0.0324 XMR per 30 days
- At 5 GH/s: about 0.000864 XMR/day, or 0.02592 XMR per 30 days
These are long-run averages before pool fees, downtime, and rejected work. They exclude transaction fees, which can add to block rewards.
Check a live Monero mining calculator or network explorer—a tool that shows blockchain activity—for an up-to-date estimate. Network difficulty, which controls how hard finding a block is, adjusts every block.
Why your actual payout may be lower
The important number is your sustained, accepted hashrate, not a brief peak shown by a benchmark.
If you mine through a pool—a group of miners sharing rewards—check the pool’s average accepted rate over at least a day. For example, if it averages 8 kH/s rather than 10 kH/s, scale the estimates down by 20%.
Other differences include:
- Uptime: Mining 12 hours a day roughly halves your expected output.
- Fees: A 1% pool fee reduces rewards by about 1%.
- Payout thresholds: You may earn small amounts daily but wait longer to receive them.
- Mining method: A CPU reaching 10 kH/s in dedicated mining software may deliver much less in a browser.
Solo mining is especially uneven. At the example 4 GH/s network rate, 10 kH/s would find one block about every 556 days on average. You could wait far longer; that is not a payout schedule.
The bottom line
At 10 kH/s, your expected earnings are 0.0324 XMR per 30 days at a hypothetical 4 GH/s network rate, before deductions. Use your real accepted hashrate and live network data to update that figure.
To decide whether it is profitable, convert the estimated XMR using the current price, then subtract electricity costs. Measure power at the wall: XMR earned and money kept are different things.
