➤If you invest $10,000 at 10% per year on average, when will you (on average) have this grow to $40,000? When will it grow to $160,000?
Time taken to grow with compound interest is the value of n in the following formula:
FV= P(1+r)^n
Where FV= Future Value, P= Present Value (given as $10,000), r= interest rate (given as 10%) and n= number of compounding period.
Case 1:
Given, FV= $40,000
Substituting the values,
40000=10000*(1+1)^n = 10000*1.1^n
1.1^n = 40000/10000= 4
Time required (n) = 14.54509 years
Calculation as follows:
Case 2:
Given, FV= $160,000
Substituting the values,
160000=10000*(1+1)^n = 10000*1.1^n
1.1^n = 160000/10000= 16
Time required (n) = 29.09018 years
Calculation as follows:
