Open enrollment season is officially underway, and if you work for an employer with 50 or more full-time staff, your benefits window is likely open now or opening soon.
Most companies give you just two to three weeks to make decisions that lock in for all of next year.
The stakes are higher than many workers realize.
Health premiums, copays, and deductibles are climbing again for 2025, and a single missed checkbox can cost you hundreds of dollars you never see on a receipt.
Here's what to check before your window slams shut. **Start with your health plan's real out-of-pocket math, not the premium.** The plan with the lowest paycheck deduction is often the worst deal if you or your family use regular care.
Add up your deductible, then your coinsurance, then your yearly prescription costs.
Compare that total across every plan your employer offers.
If you're generally healthy and rarely see a doctor, a high-deductible plan paired with an HSA can come out ahead.
Just make sure you can cover the deductible if something unexpected happens. **Don't sleep on the HSA, FSA, or dependent care accounts.** These let you pay for medical or childcare costs with pre-tax dollars, which is a straight discount on money you were already going to spend.
The catch: FSA money typically expires at year-end unless your plan offers a grace period or carryover.
Estimate conservatively, since overshooting means forfeiting the leftover.
HSAs are more forgiving because the funds roll over and can even be invested. **Review your life and disability insurance, especially if your situation changed.** Had a baby, bought a house, or started caring for a parent this year?
Those events should trigger a look at your coverage amounts.
Employer-provided life insurance is often just one or two times your salary, which may not be enough to cover a mortgage and years of expenses.
Supplemental coverage through work is usually cheaper than buying it solo, and you can often skip the medical exam. **Check your beneficiaries and any new add-on perks.** Free telehealth visits, gym reimbursements, mental health apps, and second-opinion services are increasingly bundled into plans and quietly forgotten.
Log in, open the plan documents, and see what you're already entitled to.
While you're there, confirm your beneficiary designations are current — an ex-spouse or deceased relative listed on a policy is a paperwork headache nobody wants. **Compare your spouse's or partner's options before you commit.** If you're both employed, run the numbers on each employer's plan side by side.
Sometimes it's cheaper to split coverage; sometimes one family plan wins outright.
This one comparison regularly saves families four figures a year, and it takes about 20 minutes.
Miss your window and you're generally stuck until next year unless you hit a qualifying life event like marriage, a birth, or a job change.
So treat this like a bill you can't ignore.
Our take: open enrollment isn't paperwork busywork, it's one of the few moments each year when a couple of hours can genuinely change your household budget.

Do the math, use the free accounts, and don't let the default option make the decision for you.
