Example 1: CPU Mining Monero (XMR) 

Assume you have a mid-range CPU capable of mining Monero (XMR) at 200 H/s. You can mine for 24 hours at the current price of $100 for XMR.

1. Determine the revenue from mining:

   200 H/s is the hash rate.

   Time spent mining: 24 hours

   – Daily XMR mining output is calculated as follows: (200 H/s) * (24 hours) * (XMR reward per block) / (Network hash rate)

   (Note: Monero mining pool statistics or mining calculators can be used to determine XMR rewards per block and network hash rate.)

The mining income would be $5 (0.05 XMR * $100) if you mined 0.05 XMR daily.

2. Calculate the price of electricity:

   – Let’s assume the CPU uses 80W of power.

   – Daily cost of electricity: (80W/1000) * 24 hours * kWh-rate for electricity

3. Profit Calculation

   – Daily revenue: Revenue from mining – Electricity costs

Example 2: Litecoin (LTC) CPU Mining

Let’s take a second look at CPU mining for the cryptocurrency Litecoin (LTC). Assume you have a powerful CPU capable of mining Litecoin at a hash rate of 1000 kH/s. You can use mine for 24 hours at the current price of $200 for LTC.

1. Calculate the revenue from mining:

   – 1000 kH/s of hash rate – 24 hours of mining

   – Daily LTC mining output is calculated as follows: (1000 kH/s) x (24 hours) x (LTC reward per block) / (Network hash rate)

   (Note: Litecoin mining pool statistics or mining calculators can be used to determine LTC rewards per block and network hash rate.)

If you mine 0.1 LTC every day, the mining income would be $20 (0.1 LTC * $200).

2. Determine the price of electricity:

   – Let’s say that the CPU uses 120W of power.

   – Daily cost of electricity: (120W/1000) * 24 hours * kWh-rate for electricity

3. Profit Calculation

   – Daily revenue: Revenue from mining – Electricity costs
