need help finding a formula for 401k

The final investment (the 401k) does not have a max amount so it only has two possible situations: extra contributions or not. You should only check the second to last investment (the savings) and if it has been maxed out, you should add ALL of the contributions from all three prior investments.

With all the formulas entered and autofilled, you need to then autofill the date (column A) down for the entire 360 month rows. Each row should represent a month so each date should be one month advanced from the previous cell. Then, enter a SUM function in cell G6 and autofill that down to where the investment contributions end.

The final total at the end (2/1/2050) should be $2,351,041.86
