Automatic Rebalancing Tool?

[beastmode]

Hi everyone,

Hopefully other newbies out there are thinking the same thing as me. I want to start a simple 3/4 fund portfolio and rebalance on my own. Just wondering how everyone else does their rebalancing or if there is a tool out there to make the number crunching easier?

Excel. Does all the work.

I have just such a tool built into my plan.  I use a Vanguard Target Fund.  Expense ratio = 0.10%.  4 fund portfolio with zero work on my part.  Worth considering.  Vanguard Lifestrategy funds are an alternative to Target Funds with set asset allocation.  They're not the greatest for a taxable account, though.
