Retirement Planning on Autopilot—Set It and Trust It

Sam is 41, was auto-enrolled in a 401(k) at 3%, and has not looked at it since. Sam is not anxious about retirement, just uninterested — and that is a reasonable position, provided a few settings are right, because almost all of the long-run result comes from a handful of defaults rather than from ongoing attention.

The settings that matter are short. Contribute at least enough to collect the full employer match, since that is an immediate return no investment can beat. Turn on automatic escalation, so the rate rises by a point a year without anyone remembering to do it. Hold a diversified, low-cost fund such as a target-date fund so rebalancing happens on its own. And check once a year — or when life changes — that the plan still lands where you need it to.

Time does the rest. At a 7% average return, an extra $100 a month invested from 41 to 66 grows to roughly $80,000. The same $100 started ten years later reaches only about $32,000. That gap is the cost of waiting, and it is the whole argument for spending one afternoon now rather than many later. Once the defaults are set, Retirement Buddy watches the plan and only gets in touch when one of them needs changing.
