Is $3 Million Enough to Retire? What the Monte Carlo Analysis Shows

What Spending Level Does $3 Million Support?

At a conservative 3.5% withdrawal rate: $105,000/year from the portfolio. Add Social Security for a couple ($60,000-$80,000/year combined) and you're looking at $165,000-$185,000 in total income.

The Monte Carlo analysis at this level typically shows 95%+ success rates at $150,000/year spending and 85-90% at $180,000/year. The 4% rule alone gives $120,000 from the portfolio — plenty of room with Social Security.

At $3 million, the question shifts from 'can I afford to retire?' to 'how do I optimize what I have?' Tax efficiency becomes the primary lever. The difference between naive withdrawals and optimized sequencing can be $200,000-$400,000 in lifetime taxes.

Why Is Tax Optimization More Important Than Investment Returns at $3M?

With $3 million, you're likely to face:

- $2M+ in tax-deferred accounts generating substantial RMDs at 73-75 - RMDs that push you into the 24% or 32% bracket - IRMAA surcharges on Medicare premiums ($2,000-$8,000/year extra per person) - 85% Social Security taxation - Potential 3.8% Net Investment Income Tax

A 10-year Roth conversion strategy starting at retirement could convert $800,000-$1,200,000 from traditional to Roth at 22-24%, preventing those same dollars from being taxed at 32% during RMDs. The tax savings: $80,000-$120,000+ over a lifetime.

The analysis engine models this year by year, showing the optimal conversion amount for each year based on bracket boundaries and IRMAA thresholds.

What About Estate Planning at This Level?

At $3 million plus a home, you may be approaching estate tax territory in some states (though the federal exemption is $13.61 million per person in 2025). More importantly, your heirs' tax burden depends heavily on your account mix.

Traditional IRA/401(k) inheritance: Heirs must withdraw everything within 10 years (SECURE Act) and pay ordinary income tax on all withdrawals.

Roth inheritance: Heirs still face the 10-year rule, but withdrawals are tax-free.

Taxable account inheritance: Heirs receive a stepped-up cost basis — all unrealized gains at your death are eliminated for tax purposes.

This makes Roth conversions and maintaining taxable account positions doubly valuable for estate efficiency.
