Enter the accepted shares and the rejected shares into the calculator to determine the Mining Efficiency.

## Mining Efficiency Formula

The following formula is used to calculate the Mining Efficiency.

Em = As / (As + Rs) * 100

• Where Em is the Mining Efficiency (%)
• As is the accepted shares
• RS is the rejected shares

## How to Calculate Mining Efficiency?

The following two example problems outline how to calculate the Mining Efficiency.

Example Problem #1:

1. First, determine the accepted shares. In this example, the accepted shares is given as 100.
2. Next, determine the rejected shares. For this problem, the rejected shares is given as 30.
3. Finally, calculate the Mining Efficiency using the equation above:

Em = As / (As + Rs) * 100

Inserting the values from above and solving the equation:

Em = 100 / (100 + 30) * 100 = 76.923 (%)

Example Problem #2:

Using the same process as above, first define the variables required by the formula. In this case, these values are:

accepted shares = 140

rejected shares = 20

Entering these values yields:

Em = 140 / (140 + 20) * 100 = 87.5 (%)
