A=p%281%2Br%2Fn%29%5E%28n%2At%29 Start with the compound interest formula


A=1000%281%2B0.04%2F12%29%5E%2812%2A3%29 Plug in p=1000 (the amount invested), r=0.04 (this is the decimal form of 4% interest), n=12 (compounded monthly), and t=3 (3 years)


A=1000%281%2B0.00333333%29%5E%2812%2A3%29 Divide 0.04 by 12 to get 0.00333333 (this value is approximate)


A=1000%281%2B0.00333333%29%5E%2836%29 Multiply the exponents 12 and 3 to get 36


A=1000%281.00333333%29%5E%2836%29 Add 1 and 0.00333333 to get 1.00333333


A=1000%281.1272717%29 Raise 1.00333333 to the 36th power to get 1.1272717


A=1127.2717 Multiply 1000 and 1.127137 to get 1,127.2717


So if you invest $1,000 at an interest rate of 4%, which is compounded 12 times a year for 3 years, the return is about $1,127.27 (which is rounded to the nearest cent)
