Percentage calculation (Adding a percentage)


Formula for adding a Percentage (Gain & addition)

Here is the formula how to apply a percentage to get the percentage combined with the initial amount: Initial amount * (1+((percentage rate)/100)) = Combined total after adding the amount corresponding to the percentage.

The portion corresponding to the amount of the percentage to be added to the initial amount is therefore calculated as follows : Initial amount * (percentage rate/100) = Amount corresponding to the percentage
