Daily mining profit is your share of the network hashrate times the blocks found per day, the block reward and the coin price, minus electricity. A 100 MH/s rig on a 100 TH/s network with 13-second blocks, a 2-coin reward and a 1% fee earns $26.32 a day at $2,000, or $25.60 after 300 W at $0.10/kWh.

About this tool

Ethereum itself moved to proof of stake in September 2022, so GPU rigs that once mined ETH now point their Ethash-family hashrate at chains such as Ethereum Classic. The economics are unchanged: you earn a slice of every block in proportion to your hashrate, and you pay for every kilowatt-hour the rig pulls from the wall. This calculator takes your hashrate, the network hashrate, block time, block reward, pool fee, coin price and electricity tariff, and returns daily profit, coins mined, revenue, power cost, 30-day and yearly projections, and the coin price at which the rig only breaks even. The projection assumes today's network hashrate and price hold steady; in practice both move daily, and difficulty usually rises when the price does, so treat monthly and yearly figures as a snapshot rather than a forecast.

How to use it

Describe the rig
Enter the combined hashrate in MH/s and the power draw measured at the wall in watts, not the GPU's rated TDP.
Set the network
Copy the current network hashrate in TH/s, the average block time and the block reward from a block explorer for the coin you mine.
Adjust the pool fee
Drag the slider to your pool's fee; most PPLNS pools charge between 0.5% and 2%.
Add price and tariff
Enter the coin's market price and your electricity price per kWh, then read profit, break-even price and the working.

Examples

500 MH/s farm drawing 1 kW

Your hashrate: 500
Power draw at the wall: 1000
Network hashrate: 200
Average block time: 13
Block reward: 2
Pool fee: 0
Coin price: 3000
Electricity price: 0.1

Result Profit per day ($): 97.29
Coins mined per day: 0.033231
Revenue per day ($): 99.69
Electricity per day ($): 2.40
Profit per 30 days ($): 2,918.77
Profit per year ($): 35,511.69
Break-even coin price ($): 72.22

Pool share = 500 MH/s ÷ 200000000 MH/s = 2.5000e-6
Blocks per day = 86,400 ÷ 13 s = 6646.15
Coins per day = share × blocks × 2 × (1 − 0%) = 0.033231
Revenue = 0.033231 × 3000 = 99.69
Energy = 1000 W × 24 h ÷ 1000 = 24 kWh; cost = 24 × 0.1 = 2.4
Daily profit = 99.69 − 2.4 = 97.29

A 500 MH/s share of a 200 TH/s network earns about 0.0332 coins a day; 24 kWh at $0.10 takes $2.40 off the $99.69 revenue.

100 MH/s rig, 1% pool fee

Your hashrate: 100
Power draw at the wall: 300
Network hashrate: 100
Average block time: 13
Block reward: 2
Pool fee: 1
Coin price: 2000
Electricity price: 0.1

Result Profit per day ($): 25.60
Coins mined per day: 0.013159
Revenue per day ($): 26.32
Electricity per day ($): 0.72
Profit per 30 days ($): 767.96
Profit per year ($): 9,343.55
Break-even coin price ($): 54.71

Pool share = 100 MH/s ÷ 100000000 MH/s = 1.0000e-6
Blocks per day = 86,400 ÷ 13 s = 6646.15
Coins per day = share × blocks × 2 × (1 − 1%) = 0.013159
Revenue = 0.013159 × 2000 = 26.32
Energy = 300 W × 24 h ÷ 1000 = 7.2 kWh; cost = 7.2 × 0.1 = 0.72
Daily profit = 26.32 − 0.72 = 25.6

One millionth of the network finds a share of 6,646 blocks a day; after the pool fee that is 0.01316 coins, or $26.32 against $0.72 of power.

Low coin price, $0.30 power

Your hashrate: 100
Power draw at the wall: 300
Network hashrate: 100
Average block time: 13
Block reward: 2
Pool fee: 1
Coin price: 50
Electricity price: 0.3

Result Profit per day ($): -1.50
Coins mined per day: 0.013159
Revenue per day ($): 0.66
Electricity per day ($): 2.16
Profit per 30 days ($): -45.06
Profit per year ($): -548.24
Break-even coin price ($): 164.14

Pool share = 100 MH/s ÷ 100000000 MH/s = 1.0000e-6
Blocks per day = 86,400 ÷ 13 s = 6646.15
Coins per day = share × blocks × 2 × (1 − 1%) = 0.013159
Revenue = 0.013159 × 50 = 0.66
Energy = 300 W × 24 h ÷ 1000 = 7.2 kWh; cost = 7.2 × 0.3 = 2.16
Daily profit = 0.66 − 2.16 = -1.5

At a $50 coin price the rig earns $0.66 a day but burns $2.16 of electricity, a daily loss of $1.50.

How it is calculated

coins/day = (H ÷ N) × (86,400 ÷ T) × R × (1 − f); profit = coins × P − (W × 24 ÷ 1000) × E

H: your hashrate (MH/s)
N: network hashrate, converted to MH/s
T: average block time (s)
R: block reward in coins
f: pool fee as a fraction
P: coin price in dollars
W: wall power in watts
E: electricity price per kWh

Over many blocks a miner finds a share of rewards equal to its share of total hashrate. Dividing a day's 86,400 seconds by the block time gives blocks per day; multiplying by the reward and your share gives expected coins, and the pool keeps its fee. Electricity follows the Department of Energy method: watts times hours, divided by 1,000, gives kWh. Transaction fees, uncle rewards and luck variance are left out, so real payouts scatter around this expected value.

When not to use it

Mining ETH on Ethereum mainnet, which has accepted no proof-of-work blocks since the September 2022 Merge.
Bitcoin or other SHA-256 coins, whose hashrates are quoted in TH/s or EH/s per machine.
Deciding on a hardware purchase without also counting the rig's cost and resale value.

Common mistakes

Using the GPU's rated TDP instead of wall power, which leaves out PSU losses, fans and the host system.
Entering network hashrate in GH/s while the field expects TH/s, which overstates earnings a thousandfold.
Treating the yearly figure as a forecast when network hashrate and coin price change every day.

Frequently asked questions

Can you still mine Ethereum?

No. Ethereum mainnet switched to proof of stake at the Merge on 15 September 2022, and new ETH is now issued to validators who stake. The Ethash-family algorithm lives on in Ethereum Classic (Etchash) and a few smaller chains, which is where former ETH rigs usually point their hashrate.

Where do I find network hashrate and block time?

Any block explorer or mining-pool statistics page for the coin lists the current network hashrate, average block time and block reward. Use a 24-hour or 7-day average rather than a single snapshot, since the instantaneous figure jumps around with luck.

What does the break-even coin price mean?

It is the price at which a day's mined coins pay exactly for a day's electricity. Below it the rig loses money on power alone. It ignores hardware cost, so true break-even including the rig's purchase is higher.

Why does my pool pay less than this estimate?

The estimate is an expected value. Pool luck, stale shares, payout thresholds, uncle handling and fluctuating network hashrate all make real payouts differ, sometimes by 5 to 10% over a week. Over months the average should approach the figure if your inputs were representative.

Does a higher coin price always mean more profit?

Not for long. When the price rises, more miners switch on, the network hashrate climbs and your share of each block falls. The calculator holds network hashrate fixed, so rerun it with updated numbers after a big price move.

Are transaction fees included?

No. Only the fixed block reward is counted. On Ethash-family chains fees add a small amount on top; if you want to include them, raise the block reward field by the average fee per block shown on an explorer.
