Ask most people how much they need to retire and you’ll hear a big round number. One that comes up a lot is $1.5 million. It sounds like a lot of money. And it is. But what does it actually turn into once you stop working? Let’s walk through it in plain English.
Start with the 4% rule
The 4% rule is a rule of thumb researchers came up with in the 1990s. The idea: in your first year of retirement, you withdraw about 4% of your savings. Each year after that, you take the same dollar amount, adjusted for inflation. Historically, that approach has held up for about 30 years of retirement in most market conditions.
So for $1.5 million, the math looks like this:
- $1,500,000 x 4% = $60,000 in your first year
- That works out to about $5,000 a month
- In later years, that $60,000 goes up with inflation so your buying power stays roughly the same
Here’s how a few other numbers compare using the same rule:
- $500,000 gives you about $20,000 a year
- $1,000,000 gives you about $40,000 a year
- $1,500,000 gives you about $60,000 a year
Don’t forget Social Security
Most people won’t live on savings alone. According to the Social Security Administration’s 2026 estimates, the average retired worker receives about $2,071 a month, or roughly $24,850 a year. Your own number depends on your work history and when you start collecting, so check your statement at ssa.gov.
If you had $1.5 million saved and an average Social Security benefit, your starting retirement income could look like $60,000 plus about $24,850, or around $85,000 a year.
Now the fine print
That number is a starting point, not a promise. A few things change the picture:
- Taxes. Money coming out of a traditional 401(k) or IRA is usually taxed as income. Roth withdrawals generally aren’t, if you follow the rules. So $60,000 from a traditional account isn’t $60,000 in your pocket.
- Health care. Medicare isn’t free. The standard Part B premium alone is $202.90 a month in 2026, before any other coverage or costs.
- The market. The 4% rule is based on history, not a guarantee. A big drop early in retirement can make withdrawals harder to sustain.
- How long you live. The rule was built around about 30 years. Retire early or live a long time, and the math gets tighter.
- Your house. If your home is paid off, you may need a lot less each month than someone still paying a mortgage or rent.
So is $1.5 million enough?
It depends on what your life costs. That’s the real lesson here. The question isn’t “what’s the magic number?” It’s “what do I spend, and what will I need?” Once you know that, you can work backwards. Divide the yearly amount you’d need from savings by 0.04, and that gives you a rough target to research and talk through with a professional.
Your paycheck is the beginning of your financial plan, not the end of it. Knowing what your number could look like is the first step.
