You may have noticed in the screenshot above, the “Energy usage” column. This tells me the approximate energy usage of each machine.
When all my machines are on, the energy consumption is around 440W. Two of the machines are on 24 hours, the other two are on for 12 hours per day.
This gives a monthly energy consumption in kWh of roughly:
((220 × 24 +(220 × 12))/1,000) × 30 = 237 kWh
My electricity is charged at 14p per kWh, so the monthly cost is around £33 (or $46). This means my actual profit is around $200 per month.
In addition, mining revenue counts as income for tax purposes. Everyone’s tax rate will be different, but for me in the UK, after-tax I would be left with around $120 per month.
It’s not a huge amount of money, but considering it takes zero effort I find it worth it. I mine ETH, and just keep the funds as ETH, they then also increase in value over time.
