The Million Dollar HSA · By Brian Rayhack
The most powerful retirement account may be one that most people completely overlook.
Health Savings Accounts, or HSAs, are often treated like simple spending accounts for doctor visits and prescriptions. In reality, an HSA can become one of the most valuable accounts in a long-term financial plan.

The Book
The Million Dollar HSA
In The Million Dollar HSA, Brian Rayhack whose own HSA has grown past the $1 million mark, shows how a Health Savings Account can become part of a long-term investing and retirement strategy, not just a place to save for medical bills.
Written for both new and experienced HSA owners, the book covers funding, investing, tax advantages, delayed reimbursement, and the decisions that make the biggest difference over time.
Available in Kindle, paperback, and hardcover.

Who it’s for
For anyone ready to think differently about their HSA.
You don’t need a big balance or a finance background. Whether you’re just getting started or you’ve been contributing for years, The Million Dollar HSA gives you a practical framework for one of the most misunderstood accounts in personal finance, and shows you what it can do once you stop treating it like a checking account for copays.
A clear framework for one of the most underappreciated accounts in personal finance.
You’ll learn how to:
Reduce taxes with every eligible contribution
Choose an HSA custodian that actually lets you invest
Invest an HSA for long-term, tax-free growth
Turn qualified medical expenses into future tax-free withdrawals
Avoid common mistakes that limit the value of an HSA
Think about healthcare costs as part of a broader retirement plan
A window that closes at 26, and most families never open it.
An adult child covered on a family health plan may be able to open their own HSA, with their own full family contribution limit, completely separate from their parents’. They can fund it themselves, family can help, or both. Either way, the account and every decade of tax-free growth in it belongs to them.
The day they turn 26, the opportunity is gone for good.
