How to Make $3 Million Last Through Retirement

Here are a few simple things you can do to give your $3 million a better chance of lasting through retirement.

Strategy What It Means
Keep Withdrawals Reasonable
Avoid taking more than you need.
Control Spending
Stick to a realistic retirement budget.
Stay Invested
Keep part of your portfolio invested for long-term growth.
Diversify
Spread your investments across different asset types.
Prepare for Downturns
Avoid panic-selling when markets fall.
Use Other Income
Use Social Security, pensions, and other income to cover expenses.

Keep an Emergency Fund
Have cash available for unexpected expenses.
Review Your Plan
Recheck your spending and investments regularly.

Can You Live Off the Interest From $3 Million?

Yes, it can be possible, but it depends on how much income your $3 million generates and how much you need to spend.

For example, a 4% return would generate about $120,000 a year, or $10,000 a month, before taxes.

Annual Return Interest Per Year Interest Per Month
2% $60,000 $5,000
3% $90,000 $7,500
4% $120,000 $10,000
5% $150,000 $12,500
6% $180,000 $15,000
7% $210,000 $17,500
8% $240,000 $20,000

These figures assume you withdraw only the returns and leave the original $3 million untouched. Actual returns can vary, and taxes and inflation would reduce the amount available to spend

How About Healthcare and Long-Term-Care Costs?

A $3 million retirement portfolio gives you a solid cushion, but healthcare and long-term care can still take a meaningful bite out of it.

For perspective, a single year in a private nursing home costs a national median of about $129,575, while assisted living costs about $74,400 per year

Medicare does help cover many medical expenses, but it doesn't cover everything, and long-term care generally isn't covered by Original Medicare.

Healthcare / Care Expense National Median Cost
Medicare Part B premium $202.90/month
Hospital Part A deductible $1,736 per benefit period
Skilled nursing facility $217/day for days 21–100
In-home care $80,080/year
Assisted living $74,400/year
Nursing home — semi-private room $114,975/year
Nursing home — private room $129,575/year

*Based on the standard Medicare Part B premium of $202.90/month; higher-income beneficiaries may pay more.

That's why I recommend factoring in healthcare and long-term care into your retirement plan rather than treating them as an afterthought.
