RandomX / Monero Profitability Calculator
Estimate daily, monthly, and yearly mining revenue, electricity costs, and net profit.
How this RandomX mining calculator works
This calculator is designed for miners using the RandomX algorithm, most commonly for Monero (XMR). It estimates your expected rewards based on your hashrate compared with the network hashrate, then subtracts pool fees and electricity costs to produce an estimated profit.
Core formula
Expected XMR per day = (your hashrate / network hashrate) × blocks per day × block reward × (1 − pool fee)
Profit per day (USD) = (XMR/day × XMR price) − electricity cost per day
Input guide: what each field means
- Your Hashrate: Your real sustained RandomX hashrate (not peak benchmark).
- Network Hashrate: Total hashrate securing the network. This changes constantly.
- Block Reward: XMR created per block. Monero currently has a tail emission model, often around 0.6 XMR.
- XMR Price: Your reference market price for converting XMR rewards into USD value.
- Pool Fee: Percentage retained by the pool operator.
- Uptime: Realistic percentage of time your rig is online and submitting valid shares.
- Power Usage: Total system draw at the wall (CPU + motherboard + RAM + cooling).
- Electricity Cost: Local utility rate in USD/kWh.
- Hardware Cost: Optional field used for rough break-even time.
Example: reading your results correctly
Suppose your CPU delivers 15 kH/s and your total rig draws 180W with electricity at $0.12/kWh. If your daily revenue is $2.30 and electricity cost is $0.52, your net is roughly $1.78/day before considering hardware depreciation and taxes.
A miner might look profitable at one XMR price and unprofitable a week later. That is why experienced miners track long-term averages rather than a single day snapshot.
Ways to improve RandomX profitability
1) Tune for efficiency, not just raw hashrate
More hashrate is good, but hashrate per watt is usually better. A CPU that is 10% slower but uses 30% less power may produce higher net profit.
2) Optimize memory and huge pages
RandomX is memory-hard. Proper RAM configuration, huge pages, and stable CPU settings can improve effective performance.
3) Reduce downtime
Uptime has a direct effect on rewards. Cooling, stable power, and automatic reboot monitoring can protect earnings.
4) Re-check pool fees and payout structure
Fee differences seem small, but over months they matter. Evaluate payout frequency, minimum payout threshold, and pool reliability.
Risk factors you should not ignore
- Price risk: XMR can move sharply in either direction.
- Difficulty / hashrate shifts: More miners can reduce your share of block rewards.
- Regulation: Local rules may affect mining operations, power contracts, or taxation.
- Hardware aging: Fans, PSUs, and thermals impact maintenance cost over time.
- Opportunity cost: Capital tied in hardware might perform differently elsewhere.
Final thoughts
Use this randomx mining calculator as a decision tool, not a promise engine. The most useful workflow is to run three scenarios: conservative, base case, and optimistic. If your setup only works under optimistic assumptions, your risk is likely high. If it remains acceptable under conservative inputs, your plan is more resilient.
