Early Retirement Through Long-Term Investing

Early Retirement Has Three Problems a Normal Retirement Doesn't

Retiring at 45 instead of 65 is not just a longer version of an ordinary retirement. It introduces three distinct challenges that a standard 65-year retirement largely avoids: getting at your money before retirement-account age limits, surviving a poor run of returns over a much longer horizon, and paying for health insurance without an employer or Medicare. A plan that ignores any one of them can unravel even with a portfolio that looks big enough on paper.

The investing piece — accumulating a diversified, low-cost portfolio — is the part most people focus on, and it matters. But the difference between a retirement that lasts 25 years and one that has to last 45 is in the structure and sequencing of how you draw it down. Below are the three problems and the standard ways early retirees address them.

The Bridge: Accessing Money Before 59½

In the U.S., money in a 401(k) or traditional IRA generally can't be withdrawn before age 59½ without a 10% penalty. If you retire at 45, you need a 'bridge' to cover the roughly 15-year gap. The most common bridge is a regular taxable brokerage account, which has no age restriction — you can sell shares whenever you like and owe only capital-gains tax. Many early retirees deliberately build a large taxable account precisely so they have penalty-free money in those early years.

There are also ways to tap retirement accounts early without the penalty. A Roth conversion ladder lets you move money from a traditional IRA into a Roth, then withdraw the converted amount tax- and penalty-free after a five-year waiting period for each conversion. Rule 72(t) substantially-equal-periodic-payments is another route, though it locks you into a rigid withdrawal schedule. The practical upshot: an early-retirement plan usually blends a taxable account with one of these strategies rather than relying on retirement accounts alone.

The table below compares the main ways early retirees reach money before 59½.

Sequence-of-Returns Risk: Why the First Years Matter Most

Two retirees can earn the same average return over 30 years and end up in completely different places, depending on the order in which those returns arrive. If a steep market decline hits in the first few years of retirement — while you are also selling shares to live on — you lock in losses and have less capital left to recover when the market rebounds. This is sequence-of-returns risk, and it is far more dangerous for a 45-year-old facing a 45-year retirement than for a 65-year-old facing 25.

The usual defenses are a cash or short-term bond buffer of one to three years of spending, a flexible withdrawal rate that you trim in bad years, and a somewhat more conservative withdrawal rate than the classic 4% for very long horizons (some early retirees use 3.25% to 3.5%). The buffer lets you avoid selling stocks into a downturn; the flexibility lets you ride out the worst stretches without depleting the portfolio.

Healthcare: The Cost People Forget

An early retiree loses employer health coverage decades before Medicare eligibility at 65. Health insurance and out-of-pocket medical costs are one of the largest and least predictable line items in an early-retirement budget, and underestimating them is a classic planning mistake. In the U.S., many early retirees buy coverage through the Affordable Care Act marketplace, where premiums are tied to income — which means managing your taxable income in retirement can directly lower your insurance cost.

This is one reason early retirees pay close attention to which accounts they draw from and how much taxable income they realize each year. A retiree living partly off already-taxed taxable-account principal and Roth withdrawals can sometimes keep reported income low enough to qualify for substantial premium subsidies. Healthcare planning and tax planning are tightly linked in early retirement, and both deserve as much attention as the investment portfolio itself.

Building the Portfolio That Supports It

The accumulation engine for early retirement is unglamorous: a high savings rate poured into low-cost, broadly diversified funds, held for years. A core of total-market or S&P 500 exposure — VTI or VOO at 0.03% — paired with international exposure via VXUS and a bond allocation through BND covers most of what an early retiree needs to build. Keeping costs low matters even more over a 45-year horizon, where a 0.7% fee difference compounds into an enormous gap.

As you approach the retirement date, the portfolio usually shifts toward holding a few years of spending in bonds and cash so you are not forced to sell stocks in a downturn during those fragile first years. The goal is not maximum return at retirement; it is a portfolio resilient enough to survive a bad sequence while still growing over the long decades ahead.
