Monero Mining Calculator (2025): How to Estimate XMR Profit, Power Costs & ROI

• Short answer: A Monero mining calculator estimates daily/weekly/monthly XMR and profit by combining your hashrate, power (watts), electricity price, and fees with current network difficulty and price.
• Start here: The fastest way to compare results is to try more than one calculator. A curated list lives on Monerica.com.

Best Monero Mining Calculators (Direct Links)

Core Profit Calculators

• CoinWarz Monero Mining Calculator — Enter hashrate, power (W), $ / kWh, and fees to get projected revenue, power cost, and profit.
• CryptoCompare XMR Calculator — Quick profitability view with adjustable inputs and fiat/XMR breakdowns.

Pool & Share-Time Utilities

• Monero P2Pool.Observer – Average Share Time — Estimate your expected time between shares on P2Pool at the current difficulty.

Extra Planning Tools

• WhatToMine – Monero (RandomX) — Helpful for a sanity check against other coins and to cross-compare profitability assumptions.
• Crypto DCA Calculator — Not a mining calculator, but useful to plan reinvestment or accumulation strategies alongside mining income.

What Inputs You Need (and Where to Find Them)

• Hashrate (H/s): The speed of your miner on RandomX. Check your miner’s dashboard or published benchmarks for your CPU/rig.
• Power Draw (Watts): Measure at the wall with a watt meter, or use typical TDP + overhead (motherboard, RAM, fans).
• Electricity Cost ($/kWh): Use the rate on your power bill (consider peak/off-peak if applicable).
• Pool Fee (%): Most pools charge ~0–2%. P2Pool has no central pool fee but you may see variance in payouts.
• Hardware Cost (Optional): Add this to estimate breakeven time (hardware cost ÷ monthly profit).

How to Use a Monero Mining Calculator (Step-by-Step)

• 1) Enter hashrate: e.g., a modern desktop CPU might do 6–20 kH/s depending on model and tuning (your numbers will vary).
• 2) Enter power draw: Example: 120 W total at the wall for a tuned system.
• 3) Enter your electricity price: Example: $0.12/kWh.
• 4) Add fees: Pool/dev fees if relevant (e.g., 1–2%).
• 5) Compare results across sites: Run the same inputs on CoinWarz and CryptoCompare to see a range and account for different pricing/difficulty snapshots.
• 6) Sanity check: Use P2Pool share-time to ensure your hashrate expectations align with how frequently you’ll submit shares.

Understanding the Math (In Plain English)

• Revenue: Based on your share of total network hashrate, current difficulty, and block reward, multiplied by the price of XMR if you view in fiat.
• Power Cost: Watts × hours ÷ 1000 × $/kWh. For 120 W mining 24/7 at $0.12/kWh: 0.12 kW × 24 × $0.12 ≈ $0.35/day.
• Profit: Revenue − Power Cost − Fees. Hardware cost is separate and used to estimate ROI/breakeven.

Pick the Right Tool for Your Goal

• Fast profit snapshot: CoinWarz, CryptoCompare.
• P2Pool user: P2Pool.Observer to understand share timing variance.
• Cross-coin check: WhatToMine (XMR).
• Long-term planning: DCA calculator to decide how much to accumulate or convert over time.

Accuracy Tips (Get Realistic Numbers)

• Measure at the wall: Software power readouts can be low; a watt meter gives accurate system-wide draw.
• Account for idle vs full load: Mining drives sustained load—expect higher, steadier power draw than casual use.
• Tune for efficiency: On CPUs, small undervolts and memory tuning can improve H/s per watt.
• Run multiple calculators: Prices and difficulty move constantly; comparing outputs gives you a reasonable band, not a single “truth.”

Common Mistakes to Avoid

• Ignoring electricity taxes/fees: Some utilities add delivery or tiered rates—use your effective $/kWh.
• Forgetting non-power costs: Fans, SSDs, and replacement parts add up over time—include a small per-month allowance if you want granular ROI.
• Using max boost hashrate: Sustained mining may settle below short benchmark peaks.
• Assuming constant price/difficulty: Profit swings with both; calculators show a snapshot, not a guarantee.

FAQ

• Do I need a GPU to mine Monero? No. Monero’s RandomX is designed to be CPU-friendly; most miners use CPUs.
• What pool fee should I enter? Check your pool’s website. If you use P2Pool, there’s no central pool fee, but variance is higher for low hashrates—use the share-time tool.
• Can I calculate taxes with these tools? Most mining calculators don’t handle taxes. Track income/expenses separately and consult local rules.
• Where’s the updated list of calculators? See Monerica.com for a maintained directory.

Next Steps

• Plug your real-world numbers into CoinWarz and CryptoCompare.
• If you mine on P2Pool, check P2Pool share-time to set expectations.
• Keep a bookmark to Monerica’s calculator list and re-run numbers when price or difficulty moves.
