You know what always bugged me?
You buy three ETFs, feel great about diversifying — and then you find out that 30% of your portfolio is sitting in Apple and Nvidia. Because every single one of those ETFs holds the same companies.
And that's just the beginning. What percentage of your portfolio is in financials? In tech? How much do you have in the U.S. vs. international markets? What's your actual volatility? How many years until you hit financial independence?
I wanted answers to all of this. And no tool I found gave them to me — simply, for free, and in one place.
So I built one myself.
What Is the Portfolio Analysis Tool?
It's a free tool that breaks your portfolio down to its atoms in a matter of seconds.
You enter your ETF and stock tickers, the number of shares — and you get a complete X-ray of what you truly own. From sector exposure to risk metrics to a Monte Carlo simulation of your path to FIRE.
No sign-up. No hidden fees. Just open it and go.
Why Should You Try It?
Most investors — and I'm talking about experienced ones too — have no idea what their real allocation looks like. You buy VT (total world), add QQQ (Nasdaq 100), and throw in VOO (S&P 500), and you think: "I've got three different funds. I'm diversified."
But in reality? Nvidia, Apple, and Microsoft overlap across all three funds. And suddenly, your tech sector exposure is sitting at 43% of your portfolio.
That might not be a bad thing — but you should know about it.
What Does the Tool Show You?
1. Your Positions and True Composition
Right off the bat, you see a summary: what you own, how many shares, the current price, and each position's weight in your portfolio.
Sample portfolio: 3 ETFs, total value $35,000
But the real magic is in the look-through analysis. The tool peers inside your ETFs and shows you the actual stocks you own. In the sample portfolio above, Nvidia has an effective weight of 7.9%, Apple 6.7%, and Microsoft 5.7%. And that's despite never buying a single individual stock.
The sector breakdown then reveals the reality: technology at 43%, communication services at 14%, consumer discretionary at 12%. Plus breakdowns by country and region.
Why does this matter?
Because diversification isn't about the number of ETFs you hold — it's about what's actually inside them. And without look-through analysis, you're flying blind.
2. Portfolio Characteristics and S&P 500 Comparison
This is where it gets fun.
The tool generates a radar chart comparing your portfolio against the S&P 500 across six dimensions: diversification, growth tilt, volatility, cost efficiency, stability, and concentration.
Sample portfolio vs. S&P 500 — radar chart
In our example, it looks like this:
| Metric | Portfolio | S&P 500 |
|---|---|---|
| Diversification | 93 | 42 |
| Growth Tilt | 74 | 71 |
| Volatility | 55 | 65 |
| Cost Efficiency | 100 | 97 |
| Stability | 17 | 38 |
| Concentration | 32 | 31 |
What can you read from this? The portfolio has excellent diversification (93 vs. 42 for the S&P 500) because VT covers the entire global market. Cost efficiency is maxed out — these ETFs have rock-bottom expense ratios. Stability is lower because QQQ adds tech-driven volatility.
This is the kind of analysis a financial advisor would charge you hundreds of dollars for. Here, it's free.
3. Key Risk Metrics
This section is for people who want hard numbers.
Let's walk through what you'll find:
Return Metrics — CAGR (compound annual growth rate) shows the sample portfolio returned 19% annually versus 10.2% for the S&P 500. The maximum drawdown was -25.2%, while the S&P 500 saw -33.9%. A smaller drop with a higher return? That sounds pretty good.
Risk Metrics — A Beta of 0.45 means the portfolio moves at roughly half the pace of the broader market. Volatility at 16.4% is slightly lower than the S&P 500's 17.8%. Translation: a smoother ride.
Risk-Adjusted Metrics — Sharpe Ratio of 1.02 (vs. 0.58 for the S&P) and Sortino Ratio of 1.32 (vs. 0.71). Higher numbers mean better return per unit of risk. The portfolio in this example clearly wins.
Every metric has a visual scale showing where you fall — from conservative bonds to aggressive small caps. It's perfect for quickly understanding where you sit on the spectrum.
4. FIRE Calculator: When Will You Be Financially Independent?
Now for the best part. The tool calculates how many years you have left until financial independence.
FIRE settings — fully customizable
You set a few parameters: your target monthly income, monthly contribution, inflation rate, safe withdrawal rate, current age, planned retirement age, the age Social Security kicks in, and your expected benefit. The tool then takes your portfolio's real historical data (CAGR and volatility) and runs a Monte Carlo simulation with 10,000 iterations.
The result? Five scenarios from optimistic to conservative:
Monte Carlo projection — 50% probability of FIRE in 16 years
| Scenario | Probability | Years to FIRE | Year |
|---|---|---|---|
| Best Case | 10% | 12 years | 2038 |
| Optimistic | 25% | 14 years | 2040 |
| Expected | 50% | 16 years | 2042 |
| Cautious | 75% | 18 years | 2044 |
| Conservative | 90% | 20 years | 2046 |
This isn't some oversimplified "earn 7% and you'll get there in X years" calculator. The simulation accounts for real volatility, inflation, Social Security income, and Dynamic Guardrails — a smart withdrawal strategy where you give yourself a raise in good years and tighten the belt slightly in bad ones.
5. Retirement Corridor: Will Your Money Last?
The final section is, in my opinion, the most fascinating. The tool shows you how your portfolio drawdown would look over time — and whether your money will last through retirement.
Portfolio drawdown projection over 40 years with guardrail adjustments
In our example, the portfolio survived all 40 years with a final balance of over $89 million. Over the entire period, there were 39 income raises and zero cuts. The portfolio dynamically adjusted withdrawals based on current market conditions.
And once Social Security kicks in at age 67 (approximately $2,070/month based on the 2026 average benefit), the portfolio accounts for that and reduces withdrawals accordingly. All automatically.
Who Is This Tool For?
Honestly — anyone who invests in ETFs or stocks and wants to actually understand what they own.
Beginners will love the sector breakdown and the straightforward FIRE calculator. You'll finally see what you actually own, and you'll get motivation in the form of a concrete financial independence date.
Advanced investors will appreciate the risk-adjusted metrics, stress tests, and Monte Carlo simulation. These are tools you'd normally find only behind paywalls.
FIRE enthusiasts get a complete calculator with Dynamic Guardrails, Coast FIRE, Barista FIRE, and a full retirement corridor projection. All in one place.
How to Get Started (in 30 Seconds)
- Open the Portfolio Analysis Tool

- Click Analyze Portfolio
- Done — you've got a complete analysis
No sign-up. No email required. It just works.
💡 Tip: If you want to save your results and track them over time, you can create a free account. But for a one-time analysis, it's not necessary.
Real-World Example: A Typical American Portfolio
Let's say you're a typical American investor. You invest through Fidelity, Schwab, or Vanguard, and you hold three ETFs:
| ETF | What It Is | Weight |
|---|---|---|
| VT | Total World Stock (9,000+ stocks) | ~60% |
| QQQ | Nasdaq 100 (tech-heavy) | ~25% |
| VOO | S&P 500 (U.S. large cap) | ~15% |
At first glance, that looks like solid diversification. But the tool reveals something different:
What you'll discover: Technology makes up 43% of your portfolio. The top 6 stocks (NVIDIA, Apple, Microsoft, Amazon, Meta, Alphabet) account for over 30% of your total weight. The U.S. dominates your portfolio even more than you think. Your true diversification is weaker than you assumed.
What you can do about it: Either accept it (if you believe in tech and the U.S. market, why not). Or add ETFs for emerging markets, international small caps, or bonds to balance things out. Something like VXUS (international stocks), VWO (emerging markets), or AVUV (small-cap value).
What's Coming Next?
The tool is constantly evolving. Here's what's on the roadmap:
Coast FIRE and Barista FIRE variants — coming soon. Coast FIRE shows you when you can stop contributing and just let your portfolio grow. Barista FIRE calculates what part-time income you'd need to bridge the gap.
Extended stress tests — how would your portfolio survive specific historical crises (2008 financial crisis, COVID crash, 2022 bear market).
AI-powered recommendations — personalized tips based on your portfolio's actual composition and risk profile.
Final Thoughts
The Portfolio Analysis Tool was born out of a simple need — to know what I actually own and when I'll be financially free.
No financial advisor. No expensive tools. No sign-up. Just enter your positions and get answers.
For me, it's one of the most useful tools I've ever built. And I hope it'll be just as useful to you.
