Monthly savings
Monthly savings changes the timing of the target.
Why this matters: Regular savings give compounding more money to work with before the portfolio reaches the target.
Expected real return
Expected real return shows assumed growth after inflation.
Why this matters: It changes the growth rate of the invested pot. It is an assumption, not a promise.
