Frequently asked questions
Daily profit = revenue − electricity cost − hardware amortization. Electricity cost is rate × power draw (kW) × hours run; amortization spreads the rig’s price over its lifespan.
Ignoring the rig’s upfront cost overstates profit. Spreading it across the expected lifespan (e.g. 730 days) gives a truer daily figure and a realistic break-even.
Usually electricity. At $0.10/kWh a 3 kW rig running 24/7 costs about $7.20 a day, so cheap power is the main driver of profitability.
No. Revenue swings with coin price, network difficulty and block rewards, all of which change constantly. Treat any estimate as a snapshot, not a forecast.
$10 a day in revenue. $7.20 of it never reaches you.
That's electricity's share on a 3 kW rig running 24 hours at $0.10/kWh: 0.10 × 3 × 24 = $7.20 a day, against $10 in mining revenue — leaving a daily profit of just $2.80, or $84 a month, before hardware even enters the calculation. Add a $500 hardware cost amortized over the default 730-day lifespan, and daily amortization comes to roughly $0.68, trimming profit further to about $2.12 a day and revealing a break-even of roughly 236 days — the point where cumulative profit finally repays what the rig cost to buy.
Why electricity dominates the calculation more than people expect
At a modest $0.10/kWh, a 3 kW rig running around the clock burns through $7.20 daily regardless of what the coin actually does that day — which is exactly why the electricity rate you're paying, not the coin's price, is usually the single biggest lever on whether mining is profitable at all. This calculator computes electricity cost directly from rate × power draw × hours run, making that cost visible rather than buried inside a single "profit" number.
Why hardware cost changes the honest answer, not just the exact one
Skipping hardware amortization entirely overstates profit, since it ignores the real money already spent buying the rig in the first place. Spreading that cost across the hardware's expected lifespan — 730 days by default — produces both a more honest daily profit figure and a genuine break-even date: the day cumulative profit finally covers the upfront purchase.
What this snapshot can't promise you
Mining economics shift constantly with coin price, network difficulty and block rewards, none of which stay fixed for long — treat any output here as a snapshot against today's inputs, not a forecast of tomorrow's profitability. Live coin prices, where shown, come from a client-side API call with a cached fallback, but the profit calculation itself always runs on the revenue figure you supply. For what happens after you actually sell what you mine, the crypto tax calculator covers the disposal side — mined coins are typically taxed both as income when mined and again on eventual sale, so the full picture usually spans both calculators together.
