How Much Monero Can a CPU Mine in a Day? Real Numbers by Processor
"How much Monero would my CPU actually mine in a day?" is the question every RandomX search eventually boils down to — and it has an exact, checkable answer. This page gives the per-processor numbers, computed against the live Monero network snapshot of 23 August 2026: network hashrate ~3.8 GH/s, tail-emission reward 0.6 XMR per two-minute block (720 blocks a day), XMR at ~$427. If you want the setup walkthrough instead, that lives in the Monero mining guide; the coin-by-coin picture of what CPUs can mine at all is in the CPU mining guide.
The One Number That Drives Everything
Monero's emission is fixed: 720 blocks × 0.6 XMR = 432 XMR minted per day, shared across the whole network in proportion to hashrate. So your expected daily haul is simply:
your hashrate ÷ network hashrate × 432 XMR
At today's ~3.8 GH/s network rate, every 1 kH/s of sustained RandomX hashrate earns ~0.000114 XMR per day — about 4.9 cents at current prices. That single coefficient lets you price any processor in seconds, and it is exactly the arithmetic the Monero mining calculator runs with live data. Everything below is that formula applied to realistic, tuned XMRig hashrates (huge pages on, all cores loaded).
XMR per Day by Processor (23 August 2026)
| Processor | Sustained hashrate | XMR / day | Revenue / day | Typical power |
|---|---|---|---|---|
| Intel i5 / i7 desktop (recent gens) | 4.5–6.5 kH/s | ~0.0006 | ~$0.27 | ~90 W |
| Ryzen 5 (5600 / 7600, 6 cores) | 6.5–7.5 kH/s | ~0.0008 | ~$0.34 | ~75 W |
| Ryzen 7 (5800X / 7700X, 8 cores) | 9–11 kH/s | ~0.0011 | ~$0.49 | ~105 W |
| Ryzen 9 5950X (16 cores, 64 MB L3) | ~19 kH/s | ~0.0022 | ~$0.92 | ~120 W |
| Ryzen 9 7950X (16 cores) | ~21 kH/s | ~0.0024 | ~$1.02 | ~140 W |
| Threadripper (32–64 cores) | 40–55 kH/s | 0.0045–0.0063 | $1.94–2.67 | ~280 W |
| EPYC server (96 cores, 384 MB L3) | ~90 kH/s | ~0.0102 | ~$4.37 | ~360 W |
Three patterns worth noticing. RandomX rewards L3 cache above almost everything — each mining thread wants 2 MB of it — which is why the cache-rich Ryzen 9 parts more than double a Ryzen 7 despite having only twice the cores, and why big-cache server silicon dominates the table. Second, roughly 1 kH/s per modern core with adequate cache is a serviceable rule of thumb across recent AMD generations, so newer parts can be estimated before benchmarks land. Third, laptop versions of every chip above throttle to a fraction of these numbers within minutes; the table assumes desktop cooling.
What About Phones, Old Office PCs and Idle Servers?
A recurring search theme is mining on whatever hardware happens to be lying around, so here is the honest triage. Phones are not worth it: even a flagship Android sustains only a few hundred H/s once thermal throttling kicks in — roughly $0.02 a day — while degrading a battery that costs far more to replace, and iOS bans miners outright. Old office desktops (quad-core, small cache) sit around 3–5 kH/s: ~$0.19 a day, which only clears the power bill on cheap electricity. Under-used servers are the sleeper case: dual-socket EPYC machines already paid for and already running can add 100+ kH/s (~$5/day per box) at marginal power cost, which is why "monero mining on servers" keeps growing as a query — if the hardware and the power line already exist, the arithmetic is pure upside.
Electricity: the Line Between Profit and Noise
Revenue is only half the equation. A tuned Ryzen 9 delivers roughly 150 H/s per watt, which at today's coefficient means break-even sits near $0.25–0.30 per kWh — comfortably above most residential rates worldwide, and far above the industrial rates that dominate the electricity cost by country table. Concretely: a 7950X burning ~3.4 kWh a day earns ~$1.02 and pays ~$0.43 at the US average rate of ~$0.128/kWh, netting about $0.55–0.60 a day. On Germany's ~$0.34/kWh it loses money; on Kazakhstan's ~$0.038/kWh nearly the whole dollar is margin. Efficiency-per-watt, not raw hashrate, decides whether the table above reads as income or as an expensive space heater.
From Expectation to Reality
These are pool-average expectations, and reality wobbles around them for knowable reasons: network hashrate drifts week to week (rerun the formula when it does), the XMR price moves the dollar column constantly, pools take 0–2% depending on the payout scheme, and an untuned XMRig — huge pages off, background tasks stealing cores — quietly gives up a quarter of its potential. Benchmark your own chip for thirty minutes, then hold the result against the live calculator before drawing conclusions. And if the daily figures here surprised you in either direction, the CPU mining guide explains why Monero is the only coin where this conversation is even worth having.
