The amount to be saved at the age of 65 is $1940755.74

Explanation:

To calculate the amount needed at 65 including inflation = 40000 * 1.0336 = 115931.13

Present Value of Growing Annuity = PMT / (r-g) [ 1 - { (1+g) / (1+r) }n ]

= 115931.13 / (0.045 - 0.03) [ 1 - (1.03/1.045) 20 ]

= 7728742.2 * 0.2511089

= 1940755.74
