Is contributing enough to get the full 401(k) match worth it?
Yes, and it is the single clearest decision in personal finance — the match is an immediate 50% or 100% return on your own contribution, with no offsetting cost.
A common safe-harbour formula matches 100% of the first 3% of salary you defer and 50% of the next 2%. On a $60,000 salary, deferring 5% collects $2,400 of employer money on $3,000 of your own. There is no investment available anywhere that reliably pays that.
The reason it goes uncollected is rarely disagreement. It is inertia, a default contribution rate set below the match threshold, and the fact that nobody sends a statement saying how much was left behind this year. That is why the plan on this site puts it first and prints the number.
