Answer:
You plan to save $370 per month starting today for the next 46 years at an interest rate of 9.7% will be $791046.3155
Explanation:
Rate = 9.7% / 12 = 0.808333%
Number of periods = 30 * 12 = 360
Future value = ( 1 + r) * Monthly payments * [ ( 1 + r)n - 1] / r
Future value = ( 1 + 0.00808333) * 370 * [ ( 1 + 0.00808333)360 - 1] / 0.00808333
Future value = 1.00808333 * 370 * 2,120.819723
Future value = $791046.3155
