Frequently Asked Questions

What is "moneymaxxing"?

Moneymaxxing is a viral 2026 Gen-Z finance trend — the idea that small, boring optimizations (capturing your full employer match, moving cash to a high-yield account, actually redeeming your points) add up to real money with almost no effort. It got mainstream coverage from outlets like CNBC and Good Morning America because the math is undeniable: these three leaks alone cost many households thousands per year.

How does unclaimed 401(k) employer match work?

Many employers match part of your 401(k) contributions — a common formula is "50% of your contributions up to 6% of your salary." If you contribute only 3% of an $80,000 salary under that formula, the company owes you a match on the 3% you skipped: $80,000 × 3% × 50% = $1,200 a year in free money you never collected. Contributing less than the full match cap is the single most expensive financial habit on this list, because the match is an instant 50–100% return.

How much does keeping cash in checking really cost me?

More than most people guess. A checking account paying 0.01% APY versus a high-yield savings account paying around 4% means every $10,000 in checking costs you roughly $400 a year in forgone interest. On a $15,000 balance that's about $600 a year — for the effort of one bank transfer.

Are unredeemed credit card points really "money left on the table"?

The points sitting unredeemed in your account have a dollar value — cash-back points are literally dollars you could withdraw. On top of that, money spent on debit cards or no-rewards cards earns 0% when a flat 1.5–2% cash-back card would have paid you for the same spending. Both halves count.

Can I get all of this money back?

Not all of it is "recoverable" in the same way. Unredeemed points can often be redeemed today. Cash can be moved to a high-yield account today. But an employer match you skipped in past years is gone forever — which is exactly why fixing your contribution rate going forward is the highest-priority move.

Which leak should I fix first?

Almost always the 401(k) match first: it's the largest amount and the highest return (an instant 50–100% on your contribution). Then move idle cash to a high-yield account (one-time, 15 minutes). Then set your rewards to auto-redeem so the leak stops recurring.
