Principal amount Future amount Annual interest rate Number of times per year % Number of years:
The formula for calculating time required to reach goal: t =ln(F/p)/(ln(1+r/n)n) P =initial principal n = number of times the interest is compounded per year F = future amount after time t r = annual nominal interest rate t = number of years
Example usage: If you start a bank account with $1300 and your bank compounds the interest quarterly at an annual nominal interest rate is 4.8% . Your savings goal is $1900. Using the formula above, with P = 1300, F = 1900, n = 4, and r = 4.8: t=ln(1900/1300)/(ln(1+0.048/4)X4).So, the investment period is 8 years.
