Calculate reward percentage based on individual contributions and total number of contributors.

percentages

Please feel free to correct the title. I know it's confusing.

I have the following scenario:

  • contributions to project by agent A = 2
  • contributions to project by agent B = 33
  • contributions to project by agent C = 190
  • contributions to project by agent D = 5
  • contributions to project by agent E = 33
  • project made $5000

What is the formula to calculate the percentage of those $5000 that each of the above agents should be rewarded with, based on the number of contributions that each of them made ?

I'm looking for a generic formula, not one that applies to my scenario only.

Thank you in advance for your help 🙂

Just add up the total number of contributions. Now, for each person, divide the number of contributions they did by the total number of contributions. This gives you the portion of the work they did. Then you multiply this portion by $\$5000$, because they obviously should be paid in proportion to how much work they do right?

So, for your example, the total number of contributions is $2+33+190+5+33 = 263$ contributions. Now, let's determine how much $A$ should earn. They did $2$ contributions, which isn't much compared to the groups $263$. $A$ did $\frac{2}{263}$ of the work, thus they should only earn $\frac{2}{263}$ of the profit of $\$5000$. So, $A$ should get $\frac{2}{263} * 5000 \approx \$38.02$. You can apply this method to everyone else to get their earnings.
