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 

To calculate the minimin efficiency, divide the accepted shares from the sum of the accepted and rejected shares, then multiply by 100.

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 (%)


FAQ

What are accepted shares in the context of mining efficiency?

Accepted shares refer to the number of calculations or solutions that have been successfully accepted by the mining network. They indicate the amount of work a miner has contributed to the mining process that is considered valid and contributes towards discovering new blocks.

Why do rejected shares occur in mining, and how do they affect mining efficiency?

Rejected shares occur when the solutions submitted by a miner to the network are deemed incorrect or outdated. They can be caused by network latency, hardware errors, or outdated mining software. Rejected shares negatively affect mining efficiency by reducing the proportion of work that contributes to block discovery, thus lowering the potential rewards.

How can miners improve their mining efficiency?

Miners can improve their mining efficiency by ensuring their hardware is in good condition, optimizing their mining software settings, reducing network latency by choosing a mining pool close to their geographic location, and regularly updating their mining software to the latest version to avoid rejected shares due to software issues.
