Answer:
4.18%
Explanation:
The formula for used for this calculation is given as
Future value = Present( Initial) value (1 + r)ⁿ
Where n = number of years of the investment = 13 years
Future value (Amount of the investment after 13 years)= $5,280
Present ( Initial) value (Amount of the investment before 13 years) = $3,100
r = rate of return
The formula for r is derived as:
r = (Future value/ Present (initial) value)¹/ⁿ- 1
r = ($5,280/$3,100)¹/¹³ - 1
r = 1.0418139573 - 1
r = 0.0418139573
r is always in percentage format
r = 0.0418139573 × 100
r= 4.18139573%
Approximately, the rate of return annually for 13 years = 4.18%
