Tangentially related: Does anyone know of a similar tool for comparing DCA vs. lump sum investing over a given time period?

I mean, it's probably not as clean as you'd like, but it's a ~15 minute exercise in google sheets. Hint: Use the =GoogleFinance command.

Lump Sum is just the rate of return from that date * initial investment. DCA is just that same lump sum equation but done/averaged out as many times as you've DCAed.
