Mining Rig ROI Calculator
Mining rig ROI.
Calculate crypto mining rig payback period and net profit. Enter mining rig cost and hashrate th/s to size protocol returns.
What this tool does
This calculator models the financial timeline for a mining operation by comparing equipment purchase cost against operating profit. It takes your rig cost, processing power measured in terahashes per second, daily profit per unit of hashrate, and daily electricity expense, then calculates how many days until the rig's cost is recovered through net daily earnings. The result also shows your daily, monthly, and annual profit figures—all derived by subtracting electricity costs from mining revenue. The payback period is most sensitive to changes in rig cost and daily profit per terahash; higher electricity expenses extend the timeline. A typical scenario might model a mid-range rig over several months of operation. Note that this calculation assumes stable hashrate, constant electricity rates, and fixed profit per terahash; it does not account for difficulty changes, market price fluctuations, maintenance costs, or hardware degradation. Results are for educational illustration only.

Crypto mining rig ROI calculator estimates payback period and profitability. 5,000 the securities regulator miner at 100 TH/s hashrate, 0.50 profit per TH/day, 20/day electricity = 30 daily net profit. Payback: 167 days (5.5 months). After payback: returns accrue to profit until obsolescence (typically 2-3 years for ASICs).
Example: 100 TH/s Bitcoin miner. Profit per TH varies daily - 0.50/TH/day rough estimate. Daily revenue: 100 × 0.50 = 50. Electricity: 3,000W × 0.30/kWh × 24h = 21.60. Net daily profit: 28.40. Annual: 10,366. 5,000 rig payback in 176 days. Net 2-year profit: ~15,000 (3x return).
Mining ROI risks: (1) Bitcoin price drops crash mining profitability. (2) Network difficulty rises (more competition reduces individual rewards). (3) Halvings (every 4 years, block reward halves - dramatic profitability shock). (4) the securities regulator obsolescence (next-gen miners outcompete old). (5) Electricity price spikes. Most retail mining loses money long-term - industrial-scale operations dominate due to electricity arbitrage. Cloud mining: typically scams. Better crypto exposure: a buy-and-hold approach the asset.
Run it with sensible defaults
Using mining rig cost of 5,000, hashrate of 100, profit per th per day of 0.5, daily electricity cost of 20, the calculation works out to 167 days. The defaults are meant as a starting point, not a recommendation.
The levers in this calculation
The inputs — Mining Rig Cost, Hashrate (TH/s), Profit per TH per Day, and Daily Electricity Cost — do not pull with equal force. Not every input has equal weight. Adjusting one input at a time toward extreme values shows which ones move the result most.
How the math works
Payback days = rig cost / daily net profit. Net profit = revenue - electricity cost.
Using this well
What this doesn't capture
Steady-rate math ignores real-world volatility. Actual returns are lumpy; sequence-of-returns risk matters most in drawdown; fees and taxes drag on compound growth; and behaviour changes in drawdowns can reduce outcomes below the projection. The number represents one scenario rather than a forecast.
££5,000 rig at 100 TH × ££0.5 - ££20 daily = 167 days.

Sources & Methodology
Methodology
This calculator computes the payback period by dividing the upfront mining rig cost by the daily net profit. Daily net profit is calculated as the difference between daily revenue and daily electricity costs. Revenue is derived from the hashrate and the modeled profit per terahash per day. The model assumes a constant daily profit rate and steady electricity consumption throughout the payback period. It does not account for hardware degradation, difficulty adjustments, price volatility, pool fees, maintenance costs, or changes in electricity rates. The result represents the number of days required for cumulative net earnings to equal the initial rig investment, treating profitability as linear and unchanging.
