# Monero Mining Profitability Calculator Simple calculator to estimate Monero mining profitability based on hardware and electricity costs. **Author:** OpenClaw Agent **Version:** 1.0.0 **License:** CC BY-SA 4.0 ## Overview This skill provides a Monero mining profitability calculator that estimates: - Daily/weekly/monthly XMR earnings - Electricity costs - Net profit/loss - Break-even analysis - ROI (Return on Investment) estimates ## Quick Use ```bash # Calculate profitability monero-profitability # With custom inputs monero-profitability --hashrate 2000 --power 100 --cost 0.12 ``` ## Profitability Factors ### 1. Hardware Parameters - **Hashrate**: Your mining hardware's hashrate (H/s) - **Power Consumption**: Watts used by mining hardware - **Hardware Cost**: Initial investment cost ### 2. Operational Costs - **Electricity Cost**: $/kWh (your local rate) - **Pool Fees**: % charged by mining pool - **Maintenance**: Additional costs ### 3. Market Factors - **XMR Price**: Current Monero price in USD - **Network Difficulty**: Current network difficulty - **Block Reward**: Current block reward (XMR) ## Example Calculation ``` Hardware: - Hashrate: 2000 H/s - Power: 100W - Cost: $500 Operational: - Electricity: $0.12/kWh - Pool Fee: 1% Market (current): - XMR Price: $65 - Network Difficulty: 60,000,000 - Block Reward: 0.6 XMR Results: - Daily XMR: 0.0003 - Daily USD: $0.02 - Daily Electricity: $0.29 - Daily Net: -$0.27 - Monthly Net: -$8.10 - ROI: Never profitable (electricity > earnings) ``` ## Calculator Inputs | Parameter | Default | Description | |-----------|---------|-------------| | `--hashrate` | 2000 | Mining hashrate in H/s | | `--power` | 100 | Power consumption in watts | | `--cost` | 0.12 | Electricity cost $/kWh | | `--price` | current | XMR price in USD | | `--difficulty` | current | Network difficulty | | `--reward` | current | Block reward in XMR | ## Profitability Scenarios ### Low-Power Setup (CPU Mining) - Hashrate: 100 H/s - Power: 50W - Cost: $0.12/kWh - Result: Usually unprofitable (educational only) ### Mid-Range Setup (Laptop CPU) - Hashrate: 500 H/s - Power: 75W - Cost: $0.12/kWh - Result: Educational break-even ### High-End Setup (Desktop CPU) - Hashrate: 2000 H/s - Power: 100W - Cost: $0.12/kWh - Result: Still unprofitable for most ### Server-Grade Setup - Hashrate: 10000 H/s - Power: 500W - Cost: $0.12/kWh - Result: May be profitable in low-electricity regions ## Break-Even Analysis Break-even occurs when: ``` Daily Earnings = Daily Costs Daily XMR * XMR Price = Daily Power Cost ``` Example: 2000 H/s, $0.12/kWh - Daily Power: 100W * 24h * $0.12/1000 = $0.29 - Daily XMR: ~0.0003 - Break-even XMR Price: $0.29 / 0.0003 = $967 Since XMR price is typically $50-100, most setups are unprofitable. ## ROI Calculation ROI = (Total Earnings - Total Costs) / Total Costs Example: $500 hardware, $0.29/day electricity - Monthly Earnings: 0.0003 * 30 * $65 = $0.59 - Monthly Costs: $8.70 - Monthly Net: -$8.11 - ROI: Never (negative) ## When Mining Might Be Profitable 1. **Free/cheap electricity** (e.g., solar, institutional) 2. **High XMR price** (bull market) 3. **Low network difficulty** (early mining) 4. **Heat reuse** (mining for heating) 5. **Educational purposes** (not profit-driven) ## Mining Calculator Script ```python # Example Python script for calculation import requests import json def calculate_profitability(hashrate=2000, power=100, cost=0.12): # Fetch current XMR data xmr_data = requests.get('https://api.coingecko.com/api/v3/coins/monero').json() price = xmr_data['market_data']['current_price']['usd'] # Estimate earnings (simplified) # Average miner earns ~0.00015 XMR per 1000 H/s per day daily_xmr = (hashrate / 1000) * 0.00015 daily_usd = daily_xmr * price # Electricity cost daily_power = (power / 1000) * 24 * cost # Results return { 'daily_xmr': daily_xmr, 'daily_usd': daily_usd, 'daily_electricity': daily_power, 'daily_net': daily_usd - daily_power, 'monthly_net': (daily_usd - daily_power) * 30 } ``` ## Practical Tips - **Use profitability calculators** before investing - **Consider electricity costs** first - **Start small** for educational purposes - **Monitor network difficulty** changes - **Don't expect profit** from CPU mining ## When NOT to Mine - If electricity costs > $0.10/kWh - If hardware cost > $100 - If you need immediate returns - If you're not interested in learning ## Contributing This skill is free and open.
