How Much Do You Need to Retire?
The 4% Rule Explained

One of the most common financial questions is: "How much money do I need to retire?" The answer depends on your expected expenses, lifestyle, and how long your money needs to last. The widely-used 4% Rule gives a practical starting point.

The 4% Rule

Research from William Bengen (1994) and the Trinity Study found that a retiree can withdraw 4% of their portfolio per year and, historically, the portfolio survives 30+ years without running out. This holds across most market conditions including bear markets and high inflation periods.

This rule assumes a 60/40 stock/bond portfolio and a 30-year retirement horizon. For early retirees (FIRE movement), a more conservative 3–3.5% withdrawal rate is often recommended to extend the portfolio further.

Savings Benchmarks by Age

Financial advisors often use these milestones as rough targets, assuming you want to retire around 65:

Why Starting Early Makes Such a Big Difference

Compound interest rewards early savers dramatically. Here's the difference between starting at 25 vs. 35, both contributing $300/month at 7% annual return:

Starting 10 years earlier doubles the outcome despite only $36,000 more in contributions. Time is the most powerful retirement asset.

What If You're Behind? Steps to Close the Gap

• Increase contribution rate: Even 1–2% more per paycheck adds up significantly over decades. Automate it so you never see it.
• Maximize tax-advantaged accounts: 401(k)/IRA contributions grow tax-deferred. If your employer matches, contribute at least enough to get the full match — that's an instant 50–100% return.
• Reduce fees: A 1% annual fund fee can reduce your retirement portfolio by 25% over 30 years. Use low-cost index funds where possible.
• Delay retirement by 2–3 years: Working longer has a triple benefit — more time to save, fewer years to fund, and potentially higher Social Security benefits.
• Recalibrate your retirement income needs: Many retirees spend less than they expect. Downsizing, moving to a lower cost-of-living area, or part-time work can reduce the target significantly.

What About Inflation?

The 4% rule accounts for inflation by assuming your portfolio grows faster than withdrawals. However, over 30 years, $1,000 today may only have the purchasing power of $411 at 3% inflation. Using the retirement calculator, you can model inflation-adjusted projections to see your real spending power in retirement.
