Agreed, as long as you can live with the short-term volatility. (Which for me means don't put 100% of your money in SPX.)

I think my answer would be "If you understand finance (and Excel) well enough to do this yourself, then a DIY spreadsheet (assuming it doesn't have any fat-fingered cell reference mistakes or fundamentally bad assumptions) will get you 98% of the way to what a financial adviser would offer, if not better."

A few years ago I went down this rabbit hole, and created an Excel spreadsheet that seemed reasonable. My next step was to decide if I wanted to put in some Monte Carlo simulation, but I got bored with it and stopped. It's so cumbersome to do "real" programing in Excel, there are plenty limitations there too.

Finally, have you seen the Firecalc tool? That's relatively simple, but interesting just the same, and you could use it as a sanity-check on your own calculations.

I don't think the Russell fund indices are very good for returns either. Bond index funds were disappointing for me as well. Basically, long term, you can't beat the S&P. I think I could have doubled my money over decades of investing if I just invested in an S&P 500 fund vs. spreading my money out over others which did not return as well. YMMV
I have to be careful here. A real life example comes from a simple study of a certain famous celebrity who inherited a little over 300 million from his real estate owning father around 1980. The famous celebrity son used that money to build a real estate, casino, and airline empire. He proceeded to screw it up so bad that he filed six bankruptcies over the years, finding final success in celebrity branding, ironically casting himself as a successful businessman. Anyway, this study just took that 300 million and put it into the S&P and other index funds for those forty years, and he would have come out way ahead, without the noise and turmoil.

That's the good thing about the calc's. If you put in the right numbers, it's all ok.
