Health Insurance Plan Optimizer

The cheapest premium is rarely the cheapest plan. Pit a high-deductible plan against a low-deductible one across your real expected medical use — and see exactly where each one wins.

Simplified estimate. Real plans add copays, drug tiers, network rules and family vs individual limits this model doesn't capture (coinsurance is assumed at 20%). Use it to frame the decision, then confirm details with the plan documents or a licensed broker.

Should I pick a high-deductible plan or a low-deductible plan?

Compare total annual cost, not the premium: total = premium × 12 + your share of care. Below the deductible you pay every dollar of care; above it you pay the deductible plus coinsurance, capped at the out-of-pocket max. A high-deductible plan wins at low usage, a low-deductible plan wins at high usage, and the crossover is the number that matters.

Your share of care = charges if they are under the deductible, otherwise deductible + 20% × (charges − deductible), capped at the out-of-pocket max.
Worked example (defaults on this page): at $6,000 of care, the HDHP ($280/mo, $5,000 deductible) totals $8,560 while the low-deductible plan ($480/mo, $1,500 deductible) totals $8,160 — the richer plan wins by $400.
Those same defaults cross over at about $4,750 of annual care: below that the HDHP is cheaper, above it the low-deductible plan is.
Check the worst case separately — it is premium × 12 + out-of-pocket max. On these defaults the HDHP caps at $10,360 versus $10,760, so the cheaper-on-average plan is the riskier one in a bad year.

Under the hood

The math, fully exposed

For each plan we add the yearly premium to what you'd actually pay toward care (coinsurance assumed 20%):

Annual premium = monthly premium × 12

If charges ≤ deductible: you pay the charges

Else: you pay deductible + 20% × (charges − deductible), capped at the OOP max

Total plan cost = annual premium + your share of care

Worst case = annual premium + out-of-pocket max

Premiums are the floor: you pay them whether or not you use care, so a high premium needs heavy utilization to pay off through the lower deductible.
The OOP max is your insurance against catastrophe: compare premium + OOP max across plans to see which caps your downside lower if a serious year hits.
The HSA tilts it: not modeled here, but an HDHP's HSA can cut the effective cost of every medical dollar by your tax rate — often enough to flip a close call.

Answers

Frequently asked questions

How do I choose between health insurance plans?

Compare total annual cost, not just the premium. A plan's real cost is its yearly premium plus what you'll actually pay toward care (deductible, then coinsurance, capped at the out-of-pocket max). Low-premium / high-deductible plans win when you use little care; high-premium / low-deductible plans win when you use a lot. The right plan depends entirely on your expected utilization — which is exactly what this tool models.

What is an out-of-pocket maximum?

The out-of-pocket (OOP) maximum is the most you'll pay toward covered care in a year — deductible plus coinsurance combined. Once you hit it, the insurer covers 100% of further covered costs. Premiums don't count toward it. The OOP max is your worst-case exposure, and comparing each plan's premium + OOP max tells you which protects you better if something serious happens.

Is a high-deductible plan (HDHP) worth it?

Often, if you're generally healthy and can cover the deductible in an emergency — and especially because HDHPs are HSA-eligible. The lower premiums plus the triple-tax-advantaged HSA can make the effective cost meaningfully lower than the sticker comparison suggests. If you have chronic conditions or expect heavy care, a low-deductible plan usually wins.

What is an HSA and why does it matter?

A Health Savings Account, available only with an HDHP, lets you contribute pre-tax money, grow it tax-free, and withdraw it tax-free for medical costs — a rare triple tax advantage. Money you'd spend on care anyway costs ~20–30% less when routed through an HSA, and unused funds roll over and invest for the future, effectively becoming a stealth retirement account.
