It happens every year. You get the email from HR that you ignore until the sixth reminder comes in, all caps: "ACTION REQUIRED. DEADLINE APPROACHING." Whoops.
Maybe you went to the all-company meeting a few weeks earlier, tried to make sense of the PowerPoint slides, and walked away with more questions than you started with, and no idea how to even ask them. Or maybe you're a freelancer navigating healthcare.gov in the ever-shortening enrollment window, staring at an ever-growing list of deductibles and an ever-shrinking list of provider options.
At Girlboss, we believe understanding your money — including the part that keeps you healthy — is non-negotiable. So before you click anything this year, let's get you up to speed. Here's the plain-English glossary of every term and acronym you need to know, with all the updated 2026 numbers.
Heads up for 2026: This is a rougher open enrollment year than most. Enhanced premium tax credits that had been in place since 2021 expired, and average premiums increased more than 25% nationally. Average marketplace deductibles jumped 37% from last year. The numbers below reflect the new 2026 limits — they are higher than what you may have seen in previous years.
Premium
This is what you pay just to have the insurance. If you're employed, it's deducted from each paycheck. If you're self-employed, you're writing this check every month yourself. Lower premiums usually mean higher deductibles, or less coverage overall. There's no free lunch here, just different ways to pay for it.
Deductible
The amount you're responsible for paying out-of-pocket before the insurance starts covering most costs. If you chose a high-deductible plan for the first time last year, you probably got a rude awakening when you went to the doctor and, 45 to 60 days later, received a bill for several hundred dollars.
That's the deductible doing its thing. Generally: lower deductible = higher premium, because you're asking the insurer to take on more risk. In 2026, the average marketplace deductible hit $3,786 — a 37% jump from 2025.
Co-Pay
The fixed amount you pay for a doctor's visit or prescription, usually starting around $20 to $50 (though many plans run higher). Co-pays have gotten more complicated in recent years. Some plans have co-pays that are "not subject to the deductible," meaning you just owe the co-pay even before you've hit your deductible amount. Other plans require you to meet the deductible first, then co-pays kick in. Read your plan documents on this one; it makes a real difference.
Co-Insurance
Similar to a co-pay, but a percentage rather than a flat fee. If a doctor's visit costs $500 and you have 10% co-insurance, you owe $50, and the insurer covers the rest. Co-insurance usually kicks in after you've met your deductible.
Out-Of-Pocket Maximum
The most you'll pay in a plan year before the insurance covers 100% of covered, in-network costs. No more deductibles, co-pays, or co-insurance once you hit it. In 2026, the federal cap on out-of-pocket maximums is $10,600 for individuals and $21,200 for families; a significant jump from last year's limits. Many plans set their own caps below this ceiling, so check your specific plan.
High-Deductible Health Plan (HDHP)
A plan is officially classified as an HDHP if the deductible is at least $1,700 for an individual or $3,400 for a family in 2026. HDHPs have lower monthly premiums in exchange for that higher upfront cost when you actually use care.
The tradeoff makes sense if you're generally healthy and rarely need to see a doctor; less so if you have ongoing medical needs. The key upside: HDHPs are the only plans that qualify you for an HSA (see below). Yaaaaay!
Is your deductible the same as your out-of-pocket max? With some plans, yes; which means the insurer won't start paying until you've hit the absolute ceiling. Always check both numbers before enrolling.
HSA (Health Savings Account)
If you're enrolled in an HDHP, you're eligible to open an HSA — and you should seriously consider it. An HSA lets you contribute pre-tax money to use for medical expenses. In 2026, you can contribute up to $4,300 for individual coverage or $8,550 for family coverage.
The money rolls over year to year (unlike FSAs), and after age 65 you can withdraw it for anything. It's one of the few genuinely good tax advantages available to regular people, and particularly useful for freelancers managing healthcare costs on their own.
Metal Tiers: Bronze, Silver, Gold, Platinum
On the ACA marketplace, every plan is categorized by a metal level. The metal doesn't affect the quality of care; all plans cover the same essential health benefits. The difference is how costs are split between you and the insurer.
| Bronze | Silver | Gold | Platinum |
| Lowest premium, highest out-of-pocket costs. Good if you're healthy and rarely need care. | Mid-range. The only tier that qualifies for cost-sharing reductions if your income is below 250% of the federal poverty level. | Higher premium, lower out-of-pocket costs. Good if you use healthcare regularly. | Highest premium, lowest out-of-pocket costs. Makes sense if you have high, predictable medical expenses. |
If your income is below 250% of the federal poverty level, always compare Silver plans first; cost-sharing reductions can make them significantly more valuable than the premium alone suggests.
So, How Do You Actually Choose?
The honest answer: it depends on how much healthcare you expect to use this year. If you're healthy, rarely see a doctor, and want to lower your monthly costs, an HDHP paired with an HSA is often the smartest move.
If you have ongoing prescriptions, regular specialist visits, or any planned procedures, a Gold or Silver plan with lower out-of-pocket costs will likely save you more overall even if the premium hurts upfront.
