Been diving into retirement planning lately and had to crunch some numbers on whether $2 million is actually enough to call it quits at 65. Spoiler: it's closer than you'd think, but the devil's in the details.

So here's the math that keeps coming up everywhere. Take that $2 million and apply the 4% rule. That gives you $80,000 a year to live on without touching the principal. Sounds solid on paper, right? The Bureau of Labor Statistics says the average 65-year-old spends around $52,000 annually, so you'd actually have some breathing room. Add Social Security on top of that—average person gets about $1,690 a month starting at 65—and suddenly you're looking at roughly $100,000+ combined annually. That's workable for most people.

But here's where it gets real. Your actual expenses matter way more than averages. Healthcare is the sneaky one. Experts recommend setting aside 15% of your annual income just for medical costs in retirement, even with Medicare. That's $12,000 a year right there. And if you're thinking about retiring earlier, say at 60 instead of 65, you're extending that retirement window and burning through your nest egg faster. The math changes significantly.

Taxes are another thing people underestimate. Traditional IRAs and 401(k)s hit you with income taxes when you withdraw. Capital gains taxes apply to investments. Meanwhile, Roth accounts let you sidestep some of this, but you need to plan ahead. Property taxes keep coming too, even after your mortgage is gone.

The real question isn't just whether $2 million is enough—it's whether you've actually planned where that money comes from. Are you counting on a $1 million IRA and diversifying the other half? Maybe an annuity paying $5,000 monthly? High-yield savings accounts at 4%+? Social Security at 65 or delayed until 70 for an 8% annual bump? You need multiple income streams working together.

Life expectancy matters too. Retiring at 60 and living to 90 is a 30-year runway. Healthcare costs climb as you age, so you can't just assume your expenses stay flat. That's why the detailed budget part isn't boring—it's actually critical.

Honestly, $2 million gives you a solid foundation if you're disciplined about it. The $80,000 annual withdrawal is reasonable, especially with Social Security filling gaps. But everyone's situation is different. Chronic health issues, family obligations, lifestyle preferences—these all shift the calculation. The key is running actual numbers for your life, not just going off averages.
