How much profit can i earn in a day by mining Bitcoin?

With this calculator, you can calculate the daily earnings from mining.

For example, in September 4th, 2019, if you use the Whatsminer M20S-68T (68 TH/s @ 3260W) with an electricity cost of $0.06/Kw you can mine 0.001618 bitcoin (which is worth 12.43USD) in one day.  You will see the details as the picture showns below.

However this calculation might be outdated as Bitcoin’s difficulty changes every two weeks. It’s best to run a new calculation before starting to mine with updated stats.
