| Term | Definition | Example |
|---|---|---|
| Premium | What you pay each month to maintain coverage, regardless of whether you use any care | $250/month deducted from your paycheck |
| Deductible | What you pay out-of-pocket for covered services before your insurance starts sharing costs | $1,500 deductible: you pay the first $1,500 of claims each plan year |
| Copay | A fixed dollar amount you pay for a specific service, often applied before or alongside the deductible | $30 copay for a primary care visit |
| Coinsurance | Your share of costs after the deductible is met, expressed as a percentage | 20% coinsurance: you pay 20%, insurer pays 80% of covered costs |
| Out-of-pocket maximum (OOP max) | The most you will pay in a plan year; insurer covers 100% above this | $6,000 OOP max: after you pay $6,000 total in deductible + coinsurance + copays, the rest is free |
| Feature | PPO (Preferred Provider Org.) | HDHP + HSA (High-Deductible Health Plan) |
|---|---|---|
| Monthly premium | Higher ($200–$400+ for employee-only) | Lower ($50–$150 for employee-only) |
| Deductible | Lower ($500–$1,500) | Higher ($1,700+ individual in 2026 to qualify as HDHP) |
| HSA eligible? | No | Yes — triple tax advantage (pre-tax in, tax-free growth, tax-free out for medical) |
| Best for | Frequent users: families, chronic conditions, planned procedures | Healthy, low-utilization individuals who can fund the HSA |
| Biggest risk | Paying high premiums for care you may not use | Facing the full deductible if you have an unexpected health event |
The HSA (Health Savings Account) is the only account in the tax code with a triple tax advantage: contributions are pre-tax (or tax-deductible if contributed directly), growth is tax-free, and withdrawals for qualified medical expenses are tax-free. Unused balances roll over every year — there is no 'use it or lose it' rule. After age 65, any remaining HSA balance can be withdrawn for any purpose (taxed as ordinary income, like a traditional IRA), making the HSA function as a backup retirement account.
| HSA Limit (2025) | Individual Coverage | Family Coverage |
|---|---|---|
| Annual contribution limit | $4,400 | $8,750 |
| Catch-up (age 55+) | +$1,000 | +$1,000 per eligible spouse |
Annual True Cost = (Monthly Premium × 12) + Expected Out-of-Pocket
ACA marketplace subsidies (Advance Premium Tax Credits, or APTC) are available if your employer does not offer affordable coverage and your income falls between 100% and 400% of the federal poverty level. For a single person earning $35,000–$55,000, subsidies can reduce marketplace premiums to $0–$150/month. If you are starting a job with qualifying employer coverage, you are generally not eligible for APTC for those months — but marketplace coverage is an option during the gap between graduation and your first benefits-eligible date (often 60–90 days).
1. Aging off a parent's plan at 26: Your coverage ends on your 26th birthday (or the last day of that month, depending on the plan). You have a 60-day Special Enrollment Period to join your employer's plan or buy marketplace coverage. Missing that window means waiting until your employer's next open enrollment or a qualifying life event. Act immediately — do not wait to get a bill. 2. Job change: COBRA lets you keep your old employer's plan for up to 18 months, but you pay the full premium (employee + employer share) — often $500–$700/month for employee-only coverage. For most healthy young adults, marketplace coverage with APTC or immediate enrollment in the new employer's plan is cheaper than COBRA.
Sit with the ideas.
After meeting your $2,000 deductible for the year, you receive a $5,000 bill for a covered procedure. Your plan has 80/20 coinsurance and a $6,500 out-of-pocket maximum (which includes your deductible). How much do you owe on this bill?
