Firecalc for portfolio growth during contributions
Probably well known among many, but not me. Realized I can use firecalc with a negative withdrawal amount to model my portfolio growth possibilities. The negative withdrawal being contributions of course. Seems like it's accurate, except for the Potfolio bottom value seems to max out at the starting portfolio value, no matter how big my annual contributions are. Not a big deal.
Anyway, I found it useful as I am in my 30's, thought others might not know about it yet.
