How This Number Is Calculated
The Formula
Monthly spending: $4,500
Annual spending: $4,500 × 12 = $54,000
Retirement number: $54,000 ÷ 4% = $1,350,000
The 4% withdrawal rate comes from historical research showing that withdrawing 4% of a portfolio annually has sustained portfolios across virtually all historical market conditions, including the Great Depression and 2008 financial crisis. At $1,350,000, withdrawing 4% annually produces exactly $54,000 per year — or $4,500 per month.
How Withdrawal Rate Changes Your Target
Same $4,500/month spending. Only the withdrawal rate changes.
| Withdrawal Rate | Best For | Required Portfolio |
|---|---|---|
| 3.5% | Early retirement (40–55) | $1,542,857 |
| 4.0% ✓ | Standard retirement (55–65) | $1,350,000 |
For early retirement before 55, most financial planners recommend the 3.5% rate to account for a longer retirement horizon of 40–50 years.

Frequently Asked Questions
Is $1,350,000 enough to retire on at $4,500/month? +
At a 4% withdrawal rate, $1,350,000 generates exactly $4,500/month indefinitely — assuming your portfolio earns at least 4% annually in real terms. Most diversified index fund portfolios have historically exceeded this over long time horizons. However, sequence of returns risk means a major market downturn in your first years of retirement can significantly impact sustainability. A cash buffer of 1–2 years of expenses reduces this risk.
Does $1,350,000 account for Social Security? +
No. This calculation assumes your portfolio covers 100% of your $4,500/month expenses. If you receive Social Security payments, your required portfolio is lower. For example, if Social Security covers $1,500/month, you only need your portfolio to cover $3,000/month — reducing your retirement number to $900,000.
What counts toward my $1,350,000? +
All investable assets: 401(k), 403(b), Roth IRA, traditional IRA, taxable brokerage accounts, and the invested portion of your HSA. Does not include home equity, cash savings, or non-liquid assets.
How does inflation affect the $1,350,000 target? +
The $1,350,000 figure is in today's purchasing power. Your actual nominal portfolio target at retirement will be higher due to inflation — but your actual expenses in retirement will also be higher in nominal terms. Using real returns (nominal return minus inflation) keeps everything in today's dollars, which is how CoastVest's calculators work. The target and your current savings are always directly comparable.
What is the 4% rule for retirement? +
The 4% rule states that you can withdraw 4% of your portfolio per year in retirement without depleting it over a 30+ year horizon. It's based on historical market data showing that a diversified stock/bond portfolio can sustain this withdrawal rate across most market conditions. For early retirees with 40–50 year horizons, a 3.5% rate provides additional safety margin.
