How to calculate capital growth
Know the initial investment.
Lets say you invested $100 in a share of a company.
After a month, the share price is $105.
So your monthly return can be calculated by a very simple formula. Return = (( final value-initial value)/initial value ) So the monthly return would be (105-100)/100 which is equal to 5 %.
