Open enrollment season is back, which means millions of Americans are about to make one of the biggest financial decisions of their year in about twenty minutes, often on a phone, sometimes while watching TV.
Health premiums come straight out of your paycheck before you ever see the money, and for 2025, the average employer plan costs workers roughly $6,500 for family coverage, according to KFF's annual survey.
A plan that feels cheaper each pay period can quietly cost more the moment you actually need care.
A plan with a $40 lower biweekly deduction sounds like a raise, but a high-deductible plan can leave you paying thousands before coverage kicks in.
If you or your kids take regular prescriptions, check the drug formulary line by line, because a single non-covered medication can erase a year of savings.
The second trap is the account you forgot to fund.
If you sign up for a high-deductible plan, you can pair it with an HSA, and that money goes in tax-free, grows tax-free, and comes out tax-free for medical costs.
Many employers also kick in a contribution, but only if you actually open the account.
That's free money sitting on the table while grocery prices and rent keep climbing.
Flexible spending accounts usually don't roll over much, so if you're not confident about upcoming expenses, don't overfund it.
Money trapped in an FSA in December is money you can't put toward this month's credit card balance.
Then there's the paperwork that quietly drains your checking account.
Double-check that your dependents are still listed, your doctors are still in network, and your address is current.
A stale address can mean an ID card that never arrives and a claim that gets denied while you're standing at a pharmacy counter.
If you're on a marketplace plan instead of an employer one, the stakes are even higher.
Enhanced subsidies that have kept premiums down for millions of enrollees are set to expire at the end of 2025 unless Congress acts, which means comparing plans now, not in January, can matter by hundreds of dollars a month.
Check whether your income estimate is accurate, since the wrong number can trigger a repayment at tax time.
Finally, treat your benefits portal like a bill you have to pay.
Log in, screenshot your current selections, and compare them against next year's options side by side.
Skipping it can cost a full year of smaller paychecks and bigger surprises.
None of this requires a finance degree or a crystal ball.
It requires reading the summary of benefits for the plan you're actually choosing, not the one you had three years ago.
Final Thoughts
In a year when every dollar at the grocery store feels negotiated, your benefits election deserves the same attention as your rent check.
