##### Having difficulty projecting my 401(k) growth, and other questions
« on: November 26, 2016, 03:23:06 PM »
Hi, I am struggling to figure out how to do the math on growing my 401(k). Currently, I have \$31,000 in there, and put \$18,000 a year in, on a salary of 62k. My employer matches 80% up to 5%, so essentially 4%, or \$2,480. However, they only match one time a year and it is in February sometime.

What I was trying to do was take \$18,000 / 26 (bi-weekly pay) = \$692.31 as a contribution, then compound 26 times a year, assuming 7%.

So would I take \$31,000 and multiply by (1 + .07/26) to get the new bi-weekly total, then add \$692.31, then repeat 26 times a year? And then how do I add in the \$2,480 one time a year?

If my goal is to eventually retire when I pay down a home valued at (today) 200k, about how much would I need in my account to handle the property taxes and maintenance, assuming no other debt? How many years from now would that be?

Thanks!

The easiest thing for the 401k is to assume annual compounding and use the Excel (or Google Sheets, etc.) FV function.

A common assumption is that you can use 4% of your invested assets for annual expenses, so you would need ~25X the property taxes and maintenance.
