How is mining profitability calculated?

As of Saturday, March 26, 2022, it would take 434.9 days to mine 1 Monero at the current Monero difficulty level along with the mining hashrate and block reward; a Monero mining hashrate of 4,200.00 H/s consuming 450.00 watts of power at $0.10 per kWh, and a block reward of 2.15 XMR.

For an estimate, using a 2.50% commission, net mining revenue is 0.00068445 BTC. 0.000702 BTC is calculated by 68 (miner hashrate) ÷ 85,000,000 (network hashrate) × 144 (number of blocks per day) × 6.25 (block reward) . If BTC is priced at $50,000 USD, then this M20S has a daily revenue of about $34 USD.

Therefore, the profitability of CPU mining depends on several factors such as network hash rate, hardware cost, energy cost, etc . However, make sure the coin you are mining at least makes your electricity cost back so that you can hold onto your coins for future profit.
