AI turns your savings, contributions and timeline into a monthly income figure — then shows the gap against what you'd need, and the moves that close it fastest at your age.
Half a million sounds like a lot and translates to a specific, much smaller monthly figure. Until you've done that conversion, you can't tell whether you're comfortably on track or badly behind.
What you need depends on what you'll spend, what other income you'll have, whether the mortgage is paid, and how long you live. A single universal target can only be wrong for almost everyone reading it.
Claiming a state or Social Security benefit earlier means smaller payments for longer; later means larger ones for less time. It's a genuinely consequential trade-off, and most people never sit down with it.
A proper plan from a fee-only adviser is worth it for complex situations. But most people never get far enough to know whether theirs is complex, because nobody has shown them the basic arithmetic first.
