Why do investment calculators use average returns?
Average-return modeling is a simple planning shortcut. It is useful for comparison, but it cannot capture real market path volatility.
Should I use nominal or inflation-adjusted returns?
Use nominal returns when you are also modeling inflation separately. That keeps the assumptions easier to understand and compare.
