How to Use a Mining Profit Calculator (and Avoid Rookie Mistakes)

A mining calculator is only as good as the numbers you feed it. Here's how to get an estimate you can actually trust.

Step by step

1. Pick your exact miner so hashrate and power are correct — or enter custom values.
2. Set your real electricity rate in $/kWh. Guessing here is the #1 mistake.
3. Enter your pool fee (usually 0.5%–3%).
4. Add hardware cost to see ROI and payback days.

Common mistakes

• Ignoring electricity. Power is usually your largest cost — a rig can be profitable at $0.05 and lose money at $0.15.
• Assuming difficulty stays flat. It rises over time, so today's profit is an upper bound, not a promise.
• Forgetting uptime. Real rigs don't run 100% of the time. Shave a few percent for realism.
• Using stale prices. Ours update every minute from CoinGecko, so refresh before making decisions.
