Before calculating the mining revenue, we should first understand several concepts: Difficulty, Hashrate, Block Reward, and 24h Estimated mining revenue. Take BTC for example:

Calculation of BTC mining income

Bitcoin shows how difficult it is to mine through multiple transforms, it can be simply understood as: assuming the corresponding mining difficulty is “1”, it takes about 232 times hash operating, in order to get a random number needed for a legal new block in theory, that is mining a legal new block theoretically.

So, it can be inferred that, when the mining difficulty is D, (D×232) times hash operating are needed to dig a legal new block, and R units BTC can be obtained as a block reward. If the miner's computing ability is H, then the time it takes him to complete (D×232)times hash operating equals (D×232) /H seconds.

Theoretically, the miner's mining revenue per second equals R÷ (D×232) /H BTC. 24 hours a day, a total of 24×60×60 seconds, the estimated daily mining revenue of BTC as below:

P=Hx 1/(Dx 2^32)R x (24x60x60)

For example:

Current BTC difficulty D=12720005267390.51

Reward per BTC block R= 12.5BTC

1Ph/s hashrate

Daily mining revenue= 1x10^15 x(1/12720005267390.51x 2^32)x12.5x24x60x60,

Available: P= 0.01976863 BTC

BTC and ETH are two typical crypto currencies. The mining revenue calculation of other currencies are similar to these of BTC and ETH.
