How this is calculated
Future values compound each period by (1 + r) where r is the per-period rate you supply; contributions add as either beginning- or end-of-period cash flows depending on the control.
Annualization divides or multiplies so weekly vs. monthly inputs stay consistent with the headline rate.
Inflation toggles (when present) deflate the final number so you can read “today’s dollars.”
