Principal amount Future amount Number of years Number of times per year Annual interest rate(%): 3.12
The formula for Calculating Compound Interest Rate: r =n((F/P)^1/nt -1) P =initial principal n = number of times the interest is compounded per year t = number of years F = future amount after time t r = annual nominal interest rate
Example usage: If you start a bank account with $1500 and your bank compounds the interest quarterly at an annual nominal interest rate . Find the balance after 6 years is $1900. Using the formula above, with P = 1200, F = 1900, n = 4, and t = 6: r =4X((1900/1600)^1/(4X5) -1)X100.So, the annual nominal interest rate is 3.96%.
