Häufig gestellte Fragen

Is this a guaranteed forecast?+

No. It uses a steady average return assumption for planning, but real market returns vary from year to year.

Why show inflation-adjusted value?+

Because a future balance may sound large in nominal dollars while buying less in real-world terms. Inflation-adjusted value adds useful context.
