Mining Rig ROI Calculator

Mining rig ROI.

Calculate crypto mining rig payback period and net profit. Enter rig cost and hashrate (TH/s) to estimate payback period and net profit.

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.

Quick answer: with the default values, the result is 167 days (Payback Period). Adjust the values below for your own figures.

Crypto mining rig ROI calculator estimates payback period and profitability. 5,000 ASIC 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 as profit until obsolescence (typically 2-3 years for ASICs).

Example: a 100 TH/s Bitcoin miner. Profit per TH varies daily — take 0.50/TH/day as a rough estimate, so daily revenue is 100 × 0.50 = 50. With electricity around 20/day (roughly 2,800W at 0.30/kWh over 24 hours), net daily profit is 30, or about 10,950 a year. The 5,000 rig then pays back in 167 days, and over two years nets roughly 16,900 before the rig is replaced.

Mining ROI risks: (1) Bitcoin price drops crash mining profitability. (2) Network difficulty rises as more competition reduces individual rewards. (3) Halvings (every 4 years, the block reward halves — a sharp profitability shock). (4) ASIC obsolescence, as next-gen miners outcompete older hardware. (5) Electricity price spikes. Historically, retail mining margins have been thin, with industrial-scale operations dominating through cheaper electricity. Cloud-mining contracts have frequently underperformed or proved fraudulent. Some who want crypto exposure without hardware hold the asset instead.

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.

What this doesn't capture

This is a simplified model that holds its assumptions constant. Real outcomes vary with market conditions, costs, taxes, and timing, so the figure is best read as one scenario rather than a forecast.

Example Scenario

£5,000 rig at 100 TH × £0.5 - £20 daily = 167 days.

Inputs

Mining Rig Cost:£5,000
Hashrate (TH/s):100
Profit per TH per Day:£0.5
Daily Electricity Cost:£20
Expected Result167 days
Expected Result breakdown
Daily Net Profit$30.00
Monthly Net Profit (30 days)$900.00
Annual Net Profit (365 days)$10,950.00
Daily Electricity Cost$20.00

This example uses typical values for illustration. Adjust the inputs above to match a specific situation and see how the result changes.

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.

Frequently Asked Questions

Is mining still profitable?
Margins have been shrinking. Industrial operators with very cheap electricity dominate the network, while retail miners typically pay several times more per kWh, which makes their margins thin. Bitcoin halvings (every 4 years) cut the block reward in half — a sharp profit shock. Across a full ASIC lifecycle, many retail miners have ended up underwater. Some who want crypto exposure without running hardware hold the asset directly instead.
What's hashrate?
Mining computational power, measured in hashes per second. TH/s = terahashes (trillion). PH/s = petahashes (quadrillion). Bitcoin network total: ~600 EH/s (exahashes). Your share of block rewards = your hashrate / network hashrate. As more miners join, your share shrinks - difficulty adjustments maintain ~10 minute block times.
Best ASIC miners?
Commonly cited models include the Bitmain Antminer S19/S21 series (3-10k) and the MicroBT Whatsminer M50 series. Generation matters — older ASICs tend to become unprofitable as network difficulty rises, so the newest hardware generally stays profitable longest. Resale values can fall sharply once a newer generation ships.
Cloud mining scams?
Cloud-mining contracts have a poor track record — many providers, including Hashflare and Genesis Mining, went bankrupt, and buyers have often received far less than promised once maintenance fees are deducted. The underlying logic is unfavourable: if mining were reliably profitable, a provider would generally mine itself rather than sell the hashpower. For retail crypto exposure, the main routes discussed are running hardware directly or holding the asset.
