Your earnings per computer varies depending on your hardware. For example if you have a low end computer you will not make much per month. If you have a gaming computer with good video cards you will be able to pay a few bills with that amount.
To get an exact idea of the money your computer will earn, install the software and click the "Click to start earning now!" button. After a minute or so it will start estimating your daily, monthly, and yearly earnings.
While running the software alone will not make you rich, the true earning potential comes when you refer users. You earn 20% of whatever your referral has earned. To get a good idea of how much money you can make with referrals based on the current market rates, you can view our Referral Calculator.
