Open enrollment: the one-hour benefits audit worth thousands

Every fall, a window opens for a few weeks in which you can redesign a five-figure chunk of your compensation — health coverage, tax-advantaged accounts, insurance, and benefits you may not know exist. Most employees spend less than ten minutes in it and click 'same as last year.' That default is expensive: plans change underneath you, your life changed on top of you, and the tax-advantaged accounts alone routinely leave four figures unclaimed. The audit below takes about an hour. Few hours you work all year pay better.

The one-hour agenda

1. 1
   Minutes 0–10: Reconstruct this year's actual healthcare use

   Pull your claims history or portal: doctor visits, prescriptions, any procedures, what you paid. You can't pick next year's plan without knowing what a typical year costs you — memory is a terrible actuary.

2. 2
   Minutes 10–30: Do the total-cost math on every plan tier

   For each option: (annual premium) + (your realistic expected out-of-pocket given this year's usage). Compare that number, not the premium alone. Check that your doctors and drugs are still in-network on each plan — networks and formularies change every year.

3. 3
   Minutes 30–40: Fund the tax-advantaged accounts

   HSA if you pick a qualifying high-deductible plan (limits around $4,400 individual / $8,750 family, 2026 estimates) — triple tax-advantaged and yours forever. Otherwise, size a healthcare FSA to predictable expenses only, since FSAs are largely use-it-or-lose-it. Add the dependent care FSA (up to $5,000/household, estimate) if you pay for childcare — for many families this is an automatic ~$1,000–$1,900 tax saving.

4. 4
   Minutes 40–50: Audit the insurance you're auto-renewing

   Employer life insurance beyond the free tier vs. cheaper private term; disability coverage (the most underrated benefit in the building — take the long-term option); legal plans, accident riders, and pet insurance you enrolled in once and forgot.

5. 5
   Minutes 50–60: Sweep the ignored benefits list

   401(k) match percentage (raise your contribution while you're in the portal), HSA employer seed money, tuition and certification reimbursement, commuter accounts, gym subsidies, mental health benefits, and dependent verification deadlines.

The three classic open-enrollment mistakes

• Choosing by premium alone: the cheapest premium with a $7,500 deductible can be the most expensive plan a chronically-ill family can pick — and the gold-plated PPO can be the most expensive plan a healthy single person can pick. Total annual cost is the only honest number.
• Ignoring the HSA triple play: pre-tax in, tax-free growth, tax-free out for medical — and after 65 it behaves like a traditional IRA. Funding it and investing it (not just parking cash) makes the HDHP decision about more than one year.
• Over-funding the FSA: unlike an HSA, most FSA money expires (small carryovers or grace periods aside). Fund to predictable expenses — glasses, copays, the crown your dentist already scheduled — not to the maximum.

Life changed? The defaults definitely don't fit

Marriage, a baby, a spouse's new job, a diagnosis, a kid aging off coverage, moving — each of these makes last year's elections stale. Two-income couples should run the comparison across both employers' menus, including the spousal surcharge many companies now charge for covering a spouse who has their own offer. And beneficiary designations — life insurance, 401(k) — should be reviewed in the same sitting, since they silently override wills and outlast divorces.

The bottom line

Open enrollment is a repricing event on thousands of dollars of your compensation, and 'same as last year' is a bet that nothing changed — the one outcome that never happens. Spend the hour: total-cost the plans against your real usage, fund the HSA or right-size the FSA, grab the dependent care break, audit the insurance add-ons, and bump the 401(k) on your way out. It's the best hourly rate most people will earn all year.

The worked hour: what one audit found

Here is the one-hour agenda executed by a composite employee — married, two kids, healthy year — who had rolled over defaults for three consecutive years. The findings are typical of what a first real audit surfaces (estimates; plan designs vary enormously).

Thirty-three hundred dollars for under an hour — an effective rate north of $3,500 an hour — and this employee's situation contained nothing exotic. The HDHP switch is the finding that generalizes most: for households with low expected usage, the premium gap plus employer HSA seed frequently exceeds the worst-case deductible difference, meaning the 'riskier' plan is mathematically safer at every usage level. But run your own version with last year's actual claims, because the same arithmetic flips for a household expecting a surgery or a baby — the audit's power is that it prices your reality, not a rule of thumb.

Common mistakes during the window

The first is doing the audit on the last day: enrollment platforms crash, HR is swamped, and rushed elections replicate the defaults you meant to escape — calendar the hour for the window's first week. The second is comparing plans on premium alone: the true annual cost is premium plus expected out-of-pocket minus employer contributions, and the cheapest-premium plan loses that math surprisingly often. The third is ignoring the non-medical lines because they are small: the disability elections, the legal plan, the supplemental life rates — five minutes each, and the group disability rates in particular are often the best insurance value in the entire package for anyone whose household depends on their paycheck. And write down why you chose what you chose; next year's audit starts from your reasoning instead of from scratch, which is how the hour eventually becomes twenty minutes.
