What Is QuantFlowLab?
QuantFlowLab is a data-driven investing education platform for people who want to make smarter financial decisions — without the noise, the hype, or the sales pitch.
I publish in-depth ETF comparisons, interactive calculators, and retirement planning resources backed by real numbers. Analyses come with calculations. Conclusions include the data behind them.
Who’s Behind It?
I’m M.Aiden — an engineer turned long-term index fund investor. I’ve been investing since 2018, building a portfolio around low-cost ETFs like VOO, SCHD, and VTI while raising two kids and figuring out the same financial questions most people in their 30s face.
After years of consuming investing content that was either too basic (“just buy index funds!”) or too academic (research papers with no practical advice), the gap became clear: there wasn’t enough content combining rigorous data analysis with the real-life context of someone actually making these decisions — someone balancing a mortgage, childcare costs, and retirement savings at the same time.
That’s what QuantFlowLab exists to fill.
So far, I’ve published 24+ ETF comparisons and reviews, built 7 interactive calculators, and I verify my numbers against primary sources and can walk you through the math.
What I Cover
ETF & Portfolio Strategy: Side-by-side ETF comparisons (VOO vs SPY, VTI vs VOO, SCHD vs VOO, QQQ vs VOO, and more) with current data, fee calculators, and performance charts. I focus on the ETFs that everyday investors actually hold — not exotic products or hot tips.
Retirement Planning & FIRE: Practical guides to financial independence and retirement, covering savings rate optimization, withdrawal strategies, and the math behind early retirement. I don’t sell a fantasy — I show what the numbers actually say, including when they don’t work out.
Investing Foundations: Essential knowledge for beginners: how compound interest works, what an expense ratio really costs, how to start investing with a small amount, and how to build a portfolio that survives market crashes. No jargon, no assumptions about what you already know.
My Principles
Data first. Comparisons, projections, and conclusions are backed by verifiable numbers. I cite my data sources and show my math so you can check it yourself.
Editorial independence. I don’t sell financial products or manage money. In the future, some articles may contain affiliate links to brokerages. If and when they do, this will never influence which ETF wins a comparison or what the data shows. Full details are on my Disclosure page.
Transparency about limitations. I’m not a financial advisor. I’m an investor who happens to be good with data. I share what I’d do and why — but I also share where my analysis has limits and where you should consult a professional.
Personal perspective. Many articles include my own investment decisions and reasoning. This isn’t to tell you what to do — it’s to show how one real person applies these principles with all the messiness of real life.
