I think "complicated" is the way the typical person's investments are in general. We have twice monthly contributions to DW and my 401k (into 2-3 funds in each), plus twice monthly contributions to IRA's or taxable accounts, plus twice monthly contributions to an HSA investment account. That's thirty minimum "investments" per month, ignoring any additional shifting of assets or rebalancing or one time investments or reinvested divs or CG's. Hence why I use my formula to get a "good enough" number!
For me it is roughly I start with say 100 and add 5 more into the portfolio during the quarter. So returns on that contribution are generally relatively small as a portion the whole portfolio.
