The only amount that you can change directly in the Retirement Outlook section of Retirement Planner is your "Retirement Age". The amounts below that, indicating how much money you will have at various ages, are calculated based on your set retirement age and the amounts you have entered in the other sections of Retirement Planner. The amounts for each age will update automatically any time you change the above figures.
To change your "Retirement Age", use the arrows pointing upwards and downwards next to the age displayed. The "Retirement Summary" forecast may change, depending on your set retirement age and your settings in the other sections of Retirement Planner.
