If, by the top of the interval, the overall worth is $210, merely calculating a $10 acquire on a $100 preliminary funding ($210-$200 = $10, $10/$100 = 10%) can be deceptive. It is because the extra $80 was launched mid-period. The aforementioned technique addresses this by dividing the interval into sub-periods primarily based on the money flows, calculating returns for every sub-period, after which compounding these returns.
