Mining maths from figures you supply and date
Expected mining income is one equation: your share of the network’s hashrate, times the blocks per day, times the block reward. Everything volatile in that equation (network hashrate, price, difficulty behind the block time) moves constantly, so this calculator takes no figures from thin air: you enter the current network values and the coin price, note when they are from, and it returns expected coins, gross and net proceeds after pool fees and power, the electricity price at which mining breaks even, the coin price at which it breaks even, and a payback period on hardware, each labelled as an expectation at the entered figures, not a promise about tomorrow.
Your hashrate and the network
Money in and out
Disclaimer: This calculator gives estimates for general information only. It is not financial, medical or other professional advice, and it is not a recommendation to mine or to buy any asset or hardware. Cryptocurrency prices, network hashrate and difficulty are volatile; figures computed here are expectations at the values you entered and can change materially within days or hours.
What this calculator does
It evaluates the standard expected-reward equation for proof-of-work mining and then does the economics honestly. From your hashrate and the network’s it takes your share; share times blocks per day times block reward is the expected coins per day, a statistical expectation (a small miner’s actual receipts arrive in pool payouts that smooth it, or in solo finds that emphatically do not). Coins are valued at your entered price, reduced by the pool fee, and charged your power cost at your tariff. On top of the net it computes the two break-even figures that decide real questions: the electricity price at which the entered operation stops covering its power, and the coin price at which it stops covering costs altogether, plus a hardware payback period at the current net, labelled with every assumption it rests on. Nothing is fetched or assumed behind your back; the “as of” note you enter is printed with the results so a screenshot of the answer carries its own expiry date.
How to use it
- Date your figures, because they expire. Network hashrate moves daily and price hourly; a calculation from last month’s inputs is history, not analysis. Take network hashrate and block reward from the coin’s own network statistics at the moment you calculate, and write the date in the field provided. The discipline sounds bureaucratic and is in fact the entire difference between mining maths and mining folklore.
- Power is measured at the wall. A miner’s rated watts are its silicon’s appetite; the wall draw adds power supply losses and cooling, typically 10 to 20% more. Use a meter reading if you have one. On thin margins the difference between rated and wall power is the difference between the two signs of the net figure.
- Read the break-evens before the net. The net at today’s price is a snapshot; the break-even electricity price and break-even coin price are the resilience figures. An operation that breaks even at $0.124/kWh survives tariffs and price dips that kill one balanced at $0.061, and the gap between your price and the break-even price is the honest measure of how much volatility you are being paid to absorb.
- Payback is the most fragile number on the page. It divides hardware cost by today’s net, holding price, difficulty and hashrate frozen, which the network will not do: difficulty generally rises as more hashrate joins, shrinking your share at the same price. Treat payback as the best case at current conditions, and be suspicious of any payback quoted by anyone selling the hardware.
- Solo mining is a lottery with this expectation. The equation gives the average; a solo small miner’s distribution is a long wait and an occasional block. Pool fees buy the smoothing that turns the expectation into a daily figure, which is why the fee field exists even at a painful percentage.
How it is calculated
- Your share = your hashrate / network hashrate (both converted to H/s). Blocks per day = 86,400 / average block time in seconds. Expected coins per day = share x blocks per day x block reward. Gross per day = coins x coin price. Pool fee = gross x fee %. Power per day = watts x 24 / 1,000 kWh, charged at your tariff.
- Net per day = gross – fee – power cost. Break-even electricity price = (gross – fee) / kWh per day. Break-even coin price = power cost / (coins x (1 – fee %)). Payback days = hardware cost / net per day, shown only when the net is positive.
Worked examples
A 100 TH/s machine on a large network. Illustrative figures, dated as an example: network hashrate 500,000,000 TH/s (500 EH/s), block reward 3.125 coins, block time 600 seconds (144 blocks a day). Your share is 0.00002, two hundred-thousandths of one percent, giving an expected 0.00009000 coins per day. At a coin price of $100,000 that is a gross of $9.00 a day; a 1% pool fee takes $0.09; power at 3,000 watts is 72.00 kWh a day, costing $4.32 at $0.06/kWh. Net: $4.59 per day, $137.70 per 30 days.
The same example’s break-evens. Electricity could rise to $0.1238 per kWh before the power bill alone consumed the after-fee gross. The coin price could fall to $48,484.85 before the operation stopped covering its power cost at the entered tariff. And a $4,000 machine pays back in 871.46 days at the frozen figures, a number the volatility notes on this page insist you read as a best case, because difficulty and price will both move long before day 871.
When the answer is no. Raise the tariff in the example to $0.15/kWh and power costs $10.80 a day against an after-fee $8.91: the net turns negative and the payback line is replaced by the statement that the hardware does not pay back at these figures. A calculator willing to print that sentence is doing its job; most of the value in mining maths is in the operations it talks you out of.
Reading your results
Read the share first to calibrate expectations: at small shares you are buying a tiny slice of a very large lottery that pools convert into rent-like income, and the variance discussion is not decoration. Then read net as a function of its two break-evens, asking how much room each leaves: price can halve (it has, repeatedly, in this asset class) and tariffs only ever drift one way in most places. Finally, re-run the page with a higher network hashrate before committing money, modelling the difficulty growth that history says to expect; an operation that only works if the network stops growing is an operation designed to expire.
Limitations
- Expectations, not distributions. Coins per day is the statistical mean. Pool miners see something near it; solo miners see mostly zero and occasionally a block. Neither experience contradicts the equation, and neither is promised by it.
- Difficulty and price are frozen at your inputs. Both move, difficulty usually upward over time. The calculator’s date note exists because its outputs inherit the shelf life of the figures entered, and any reuse of an old result without fresh inputs is misuse the page cannot prevent, only label.
- Costs beyond power and pool fees are yours to add. Hosting, maintenance, downtime, hardware failures, taxes and the eventual resale value of the machine all affect a real operation and none are in the fields. The net here is net of the stated costs, and the page names them so the missing ones are visible by their absence.
- Block rewards change by protocol schedule. Halvings and fee-market shifts alter the reward input on dates the protocol sets. An old reward figure is the quietest way for a mining calculation to go wrong; the “as of” habit catches it.
Frequently asked questions
How much will I make mining?
At the figures you enter, the page’s net line is the expected answer, and the honest rider is that the figures move. Mining income is a share of a fixed daily issuance, valued at a volatile price, minus a power bill that does not care about either. Worked with current network data, the answer is meaningful for weeks, not years, and the break-even lines tell you how wrong the price can go before the answer changes sign, which is the part of “how much” that planning actually needs.
What is the break-even electricity price?
The tariff at which your power cost exactly consumes your after-fee mining gross: (gross – pool fee) divided by your daily kilowatt-hours. Above it, the operation pays the power company for the privilege of mining, at the entered price and difficulty. It is the single most useful comparison between two machines or two locations, because it collapses efficiency, hashrate and tariff into the one threshold each must beat, and this page prints it beside every result.
Why does difficulty matter if I enter network hashrate?
They are two readings of the same competition: difficulty is set by the protocol so that blocks arrive on schedule given the total hashrate, so a rising network hashrate and rising difficulty are the same event seen from two sides. Entering hashrate is enough for the reward equation. Difficulty matters to your planning because its trend is your share’s trend: at a fixed personal hashrate, a network that doubles halves your expected coins, whatever the price does.
Is mining profitable?
For a specific machine, tariff and moment, the net line answers at the entered figures, and the worked example shows both signs of the answer at different tariffs for identical hardware. As a general question it has no standing answer, which is precisely why the calculator takes the figures from you rather than advertising a rate. Anyone quoting mining profitability without a date, a tariff and a network hashrate is marketing, and the fields on this page are the three questions to ask them.
