Since I'm a control freak, I've never used Vanguard's "maximize" option for automatic contributions, but I decided to start doing it this year to eliminate the human factor.
I have some extra money lying around and want to just toss it in the IRA now to get close to finishing it off early but I want to know how that affects the "maximize" function. Let's say my auto contributions are on the 15th and were previously going at the autopliot $458.33 to get the yearly $5500. However, on the 10th I decide to put enough in that it brings me within, say $300. Will Vanguard automatically change my contribution to $300 for the 15th and then stop for the rest of the year? Or will it spread the $300 over the rest of the year?
tl:dr, will Vanguard's automatic contribution "maximize" feature adjust downward in a given month if you toss a bunch of cash into your IRA?
