How electricity rate changes your profit

Using your current hashrate, power draw and coin price, here's your net daily profit at a range of electricity rates.

Profitability forecast (your assumptions)

This is an explicit "what-if" projection, not a prediction \u2014 it applies the difficulty growth and price change rates you set above (in "Forecast assumptions") month by month, so you can see how a rising network hashrate and a changing coin price would affect this setup over time. Set both to 0% to see a flat, no-change baseline instead.

How hardware efficiency changes profit

Illustrative efficiency classes (in joules per terahash) at a reference 100 TH/s and your current network hashrate, coin price and electricity rate — not specific named products, since exact specs and prices change constantly. Compare against your actual hardware's rated efficiency.

Understanding mining profitability

Proof-of-work mining pays participants for contributing computing power (hashrate) to secure the network and validate transactions. Miners compete to solve a cryptographic puzzle roughly once every block interval; whoever solves it first earns the block reward. Since individual odds are vanishingly small at today's network scale, most miners join a pool that combines hashrate and pays out a steady share proportional to each contributor's power.

Where Blocks Per Day = 86,400 seconds ÷ average block time. This is the same hashrate-share formula used by established mining calculators, and it's mathematically identical to the difficulty-based version (Network Hashrate = Difficulty × 2³² ÷ Block Time) — this calculator asks for network hashrate directly since it's a more intuitive number than raw difficulty, without changing the underlying math.

Electricity is usually the number that decides profitability

Mining hardware is a one-time cost; electricity is a continuous expense for as long as the miner is plugged in. A rate difference of just a few cents per kWh compounds every single day the machine runs, which is why large-scale operations aggressively chase the cheapest reliable power — often below $0.05/kWh through direct deals, stranded energy, or renewables — rather than simply buying the newest hardware. Two identical miners at $0.05 versus $0.15 per kWh can be the difference between solidly profitable and losing money outright.

Break-even electricity rate

This is the electricity price at which your revenue exactly covers your power cost, leaving zero profit before accounting for hardware. At the default scenario on this page — 300 TH/s, a 750 EH/s network, a $95,000 coin price and a 1% pool fee — the break-even rate works out to about $0.20/kWh. Below that rate you're profitable before hardware costs; above it, running the miner loses money regardless of how much you mine.

Hardware payback and depreciation

Payback period is simply hardware cost divided by daily net profit. In the default scenario, a $4,500 miner earning about $12.79 a day pays for itself in roughly 352 days — just under a year, assuming price, difficulty and electricity rate all stay exactly where they started. In practice none of those three stay fixed: difficulty tends to trend upward, newer and more efficient hardware keeps launching, and prices are volatile — all of which mean real-world payback periods usually run longer than a static day-one estimate.

How a halving affects profitability

A halving cuts the block reward in half overnight, which — at unchanged price and difficulty — cuts your revenue in half too, while your electricity cost stays exactly the same. In the default scenario, halving the reward from 3.125 to 1.5625 coins drops daily net profit from about $12.79 to roughly $4.32 — a much bigger hit than the 50% revenue cut alone, because the fixed electricity cost eats a larger share of a smaller revenue number. Coin prices have historically tended to rise around halvings, but that's never guaranteed, and older or less efficient hardware is often the first to become unprofitable and get switched off.

Difficulty tends to rise, eroding a fixed hashrate's share

As more hashrate joins a network, difficulty adjusts upward to keep block times steady, which shrinks the revenue of any hashrate that stays fixed. A 20% increase in network hashrate — with your hashrate, the price and the reward all unchanged — drops daily profit from about $12.79 to roughly $9.97 in the default scenario, purely from your shrinking share of the network. This is why a profitable day-one snapshot tends to decay over the life of a piece of hardware unless the coin's price rises to compensate. The "Profitability forecast" section further down this page lets you set your own assumed monthly difficulty growth and price change rates and see this erosion (or growth) played out month by month, rather than relying on a single static snapshot — set both to 0% for a flat, no-change baseline instead.

A worked example

300 TH/s against a 750 EH/s network, a 3.125-coin block reward, a 600-second block time, and a $95,000 coin price mines about 0.00018 coins a day — worth roughly $17.10 in gross revenue. A 1% pool fee brings that to about $16.93, and 3,450 watts at $0.05/kWh costs about $4.14 a day in electricity, leaving a net profit of roughly $12.79 a day, or about $383.67 a month.

Glossary of terms

Hashrate

The computing power devoted to mining, measured in hashes per second (commonly GH/s, TH/s, PH/s or EH/s).

Network hashrate

The combined hashrate of every miner on the network, which can be derived directly from the current difficulty and average block time.

Difficulty

A network-set target that adjusts periodically to keep block times steady as total network hashrate changes.

Block reward

The number of new coins paid to whoever finds a valid block, set by the network's protocol and reduced at scheduled halvings on some chains.

Mining pool

A group of miners who combine hashrate and split rewards proportionally, in exchange for a small fee, converting a rare solo payout into steady income.

Break-even electricity rate

The power price at which mining revenue exactly equals electricity cost, leaving zero profit before hardware is considered.

Payback period

Hardware cost divided by daily net profit — the time needed to recover a miner's purchase price at current conditions.

J/TH (joules per terahash)

A standard efficiency metric for mining hardware — energy consumed per unit of hashing power; lower is more efficient.

How to use this calculator

Common mistakes & tips for evaluating mining profitability

• Treating a day-one snapshot as a multi-year guarantee. Difficulty tends to rise and hardware becomes relatively less efficient over time — build a buffer into any payback estimate.
• Underestimating electricity as the dominant cost. A few cents per kWh matters more over a hardware's lifetime than most people expect — compute your break-even rate before committing.
• Ignoring pool fees when comparing pools. A slightly higher advertised payout with a much higher fee can net out worse than a lower headline rate with a smaller fee.
• Attempting solo mining with modest hashrate. At most networks' current scale, solo mining with anything less than serious hashrate can mean waiting years for a single payout — a pool converts that into steady income.
• Forgetting cooling, hosting and maintenance costs. This calculator covers electricity and hardware price directly, but real operations often have additional overhead not reflected in a basic projection.
• Ignoring price risk on top of mining risk. Coins mined are still subject to price volatility after they're earned — a profitable mining operation can still lose money in dollar terms if the coin's price falls faster than it's mined.

Solo vs. pool mining — a side-by-side example

300 TH/s against a 750 EH/s network, 3.125-coin block reward, $95,000 coin price — the same hashrate, mined two different ways.

Both approaches have almost exactly the same long-run expected value — pool mining simply trades a small fee for converting an extremely rare, massive payout into steady, predictable income. For nearly any individual miner, the practical choice is the pool: a real person can't wait out a multi-decade lottery, no matter how mathematically fair its expected value is.
