What Is Healthcare Cost Bridge?
The healthcare cost bridge is the total amount you'll likely need to cover private health insurance premiums for the years between retiring and turning 65, when Medicare eligibility begins in the U.S.
It's one of the most underestimated costs in early retirement planning, because it doesn't show up in a typical "annual expenses" estimate the way rent or groceries do, and because premiums for self-purchased coverage tend to rise faster than general inflation.
To put real numbers on the scale of this cost: a 55-year-old early retiree who retires in 2025 faces 10 years of private coverage before Medicare. A silver-tier ACA marketplace plan for a single 55-year-old currently runs roughly $700-900/month in most markets before subsidies, or $8,400-10,800/year. At 6% annual healthcare inflation, a $9,000/year starting premium grows to over $14,000/year by year 10. The total over the decade exceeds $110,000 in cumulative premiums alone, before any out-of-pocket costs. There are three levers worth knowing about. First, ACA marketplace subsidies: early retirees with low reportable income may qualify for substantial subsidies that cap premiums as a percentage of income. Second, managing retirement income below subsidy cliffs: because subsidies phase out at specific income thresholds, careful Roth conversion and capital gain timing can keep premiums dramatically lower. Third, HSA balances built during working years can pay premiums tax-free for Medicare Part B, D, and supplemental coverage after 65. Building your healthcare bridge estimate into your FIRE number from the start is far less stressful than discovering it as a surprise after you've already retired.
How This Calculator Works
The calculator compounds your current estimated annual premium forward at an assumed healthcare inflation rate for each year you'll need private coverage, then sums the total.
Personal Considerations
Healthcare cost is one of the few retirement expenses tied directly to health itself, which makes it emotionally loaded in a way grocery budgeting isn't. Some people over-save here out of health anxiety; others under-save because they don't want to think about it. Both are worth noticing as a bias rather than a forecast.
If a chronic condition or family health history is part of your picture, this is a place where getting a second, more personalized estimate (from a broker or your current insurer) is worth more than refining the inflation assumption in this calculator. The number here is a planning estimate, not a substitute for that conversation.
Planning fallacy and confirmation bias are the two biases most likely to cause people to underestimate this cost significantly. Planning fallacy produces a systematic tendency to anchor healthcare cost estimates on what you currently pay through your employer, which is often 60-80% subsidized and bears little resemblance to what marketplace coverage actually costs. Confirmation bias leads people to seek out best-case subsidy scenarios and to assume those scenarios will apply to them, while discounting the ACA subsidy cliffs and premium increases that can eliminate those savings quickly. The corrective is to look up actual current marketplace premiums in your zip code for your age bracket at HealthCare.gov and use that as your starting number, not a national average.

Frequently Asked Questions
Subsidies can meaningfully reduce this cost depending on your reported retirement income, which you control more than you might think in early retirement. Run a lower premium estimate to model a subsidized scenario.
Usually not, COBRA typically means paying the full unsubsidized premium your employer previously partially covered, often making it more expensive than a marketplace plan, though it preserves your existing provider network for up to 18 months.
Medical costs have historically outpaced general consumer inflation due to rising drug costs, administrative overhead, and an aging population, though the exact gap varies year to year.
