Answer:
dividing the asset's cash distributions during the period, plus change in value, by its beginning-of period investment value
Step-by-step explanation:
Rate of return of an investment is defined as the ratio of change of value or/and cash flows from an asset and it's initial cost of investment.
It measures the profit that a business owner gets from an asset in a given period of time.
Cash flows includes interest payments and dividends.
When rate of return is positive it results in profit but when it is negative the business is incurring a loss.
Usually rate of return is calculated within the period of one year, and is referred to as annual rate of return.
