Mining Profit Calculator
Estimate what a mining rig actually earns using live network difficulty and prices. Unlike most calculators, this one lets you apply a difficulty growth rate to the projection — because assuming difficulty never changes is what makes payback periods look far shorter than they turn out to be.
Difficulty growth assumption
+20% / yearAs more machines join, your share of the network shrinks and the same rig earns less. Holding difficulty flat is the single biggest reason mining calculators overstate returns.

Frequently asked questions
How is mining revenue calculated?
Your hashrate is divided by the total network hashrate to get your share, then multiplied by the number of blocks mined per day and the block reward. If you control one millionth of the network you earn roughly one millionth of the coins issued. Using the share of network hashrate rather than the Bitcoin-specific difficulty formula means the same maths works correctly for Scrypt, RandomX, Etchash and kHeavyHash chains, which define difficulty differently.
Why does the payback estimate change so much with the difficulty setting?
Because it compounds. If network difficulty rises 20% a year, the same machine earns roughly 17% less each year while your electricity bill stays exactly the same. Over a three or four year horizon that gap dominates everything else. Most calculators quietly hold difficulty flat, which is why their payback figures are consistently optimistic.
What difficulty growth rate should I use?
There is no correct answer, and the tool deliberately shows you why. Bitcoin's own trailing figures, measured from real difficulty adjustments, come out around -3% a year over the last twelve months but over +30% a year measured across three years. The honest approach is to check whether the machine still makes sense under the pessimistic figure, and treat anything better as upside.
What is break-even electricity price?
The cost per kWh at which mining revenue exactly covers your power bill. Below it you make money on power; above it every day of mining costs you money regardless of how much the hardware cost. For most current-generation Bitcoin ASICs this figure sits somewhere between three and nine cents, which is why serious mining happens where power is cheap rather than where miners live.
Does this include the block reward that goes to masternodes or dev funds?
No, and that matters. The block rewards here are the miner's share only. Zcash issues 1.5625 ZEC per block but the miner receives 1.25 after the dev fund; Dash splits its reward with masternodes so miners get roughly 40%. Using the headline block subsidy for those chains would overstate revenue substantially.
Why does mining Litecoin also mine Dogecoin?
The two chains are merge-mined: they share the Scrypt algorithm, so a single machine submits work to both simultaneously and earns rewards on each without extra electricity. Real-world revenue for a Scrypt ASIC is therefore roughly the sum of the two. This calculator shows one coin at a time, so add the figures together for a combined estimate.
How accurate are the hardware presets?
They are manufacturer-rated hashrate and wall power figures, and only machines whose specifications could be verified are listed. Real units vary with firmware, ambient temperature, PSU efficiency and how hard they are tuned, typically by a few percent either way. Every field stays editable, so if you know your machine's measured figures, use those instead.
What is not included in these estimates?
Quite a lot. Cooling and ventilation costs, hosting or colocation fees, hardware failures, transaction-fee revenue beyond what the current block reward reflects, resale value of the machine, and tax. It also assumes a constant coin price, which is the single largest unknown — a price move will swing profitability far more than difficulty ever does.
Where does the network data come from?
Difficulty, block times, block rewards and prices come from WhatToMine, refreshed every ten minutes; the trailing difficulty growth figures come from mempool.space's record of actual Bitcoin difficulty adjustments. Prices were cross-checked against CoinGecko and agreed within half a percent. If the upstream data is unavailable the calculator falls back to a stored snapshot and says so.
