Fill in all the values (except "Nest Egg") and see hou much money you'll have for your retirement under different scenarios. You can change the values and resubmit the form as many times as you like. You must fill in the two "Age" variables. The "Annual return" variable has a default inflation-adjusted value (7% = 8% growth minus 1% inflation) which you can change to reflect your greater optimism or pessimism.
