Can I retire at 45 with $4 million?

The short answer

$4 million at age 45 supports about $130,000 per year before tax, $10,833 a month, using a 3.25% withdrawal rate across a 50-year retirement through age 95. Set aside roughly $180,000 for healthcare before Medicare and the sustainable figure drops to $124,150.

What actually decides it at 45

The withdrawal rate is the easy part. These are the constraints specific to retiring at this age.

You need 20 years of health coverage before Medicare

Medicare starts at 65. Retiring at 45 means covering yourself for 20 years first: through an ACA marketplace plan, COBRA or a spouse's employer plan. At roughly $9,000 per person per year, that's about $180,000 you should treat as spoken for. It is the single most underestimated line item in early retirement.

Planning an early exit

Retirement accounts carry a 10% penalty at this age

At 45, withdrawals from IRAs and 401(k)s are 14.5 years away from being penalty-free. Bridging that gap usually means taxable brokerage funds, Roth contributions (withdrawable at any time), a 72(t)/SEPP schedule or a Roth conversion ladder started five years ahead.

Which account to draw first

Social Security is 17 years away at the earliest

Benefits cannot start before 62, and claiming at 62 permanently reduces them by about 30% versus waiting until 67. For 17 years your portfolio carries the full load alone, which is exactly the stretch where a bad sequence of returns does the most damage.

Why the first years matter most

A 50-year retirement changes the math

Planning through 95 means this portfolio has to last 50 years. The 4% rule was built on 30-year horizons, so we use 3.25% here instead. That single adjustment is the difference between $160,000 and $130,000 of sustainable annual spending, and it is why generic 4% answers mislead people retiring early.

How the rate is derived

Common questions

Can you retire at 45 with $4 million?

$4 million at age 45 supports roughly $130,000 per year before tax, using a 3.25% withdrawal rate over a 50-year retirement. Whether that is enough depends on your actual spending, and on covering roughly $180,000 of healthcare before Medicare at 65.

How much can you withdraw per year from $4 million?

At a 3.25% rate, $4 million produces about $130,000 a year, or $10,833 a month. At a flat 4% it would be $160,000, and at a conservative 3% it would be $120,000. The rate matters more than most people expect over a 50-year horizon.

Can you access retirement accounts at 45 without a penalty?

Not directly, IRA and 401(k) withdrawals before 59½ generally carry a 10% penalty. Most people retiring at 45 bridge the gap with taxable brokerage assets, Roth contributions, a 72(t)/SEPP schedule or a Roth conversion ladder started five years in advance.

Assumptions on this page. Spending figures are pre-tax and in today's dollars, modelled through age 95 (50 years). The 3.25% rate is scaled to that horizon rather than fixed at 4%, because the 4% rule was derived from 30-year retirements. Social Security, pensions and other income are excluded, including them raises what this portfolio can support. Healthcare before Medicare is estimated at $9,000 per person per year. These are planning estimates, not advice; run your own numbers and read the model's limitations.
