Free ETF education built around the questions real investors ask: which fund, which broker, what does this fee actually cost me over 30 years. CFA® Charterholder reviewed. No product placement.
ETF BFF (etfbff.com) launched in 2026, but the idea had been sitting around for five years before that — the product of watching smart people make expensive, avoidable mistakes with their investments simply because no one had explained the basics clearly.
The site is a free ETF investing education platform built for beginner and intermediate investors who want to understand exchange-traded funds without jargon, sales pitches, or paywalls. That means plain-English guides on ETF basics, expense ratios, the 3-fund portfolio, bond ETFs, and dividend ETFs. A fee calculator that shows the real 30-year cost of picking a 0.68% fund over a 0.03% one. ETF comparison pages, 389 factsheets, a brokerage guide, a 100-term glossary, an ETF archetype quiz, and a portfolio analyzer. All free. No account required.
Every piece of content is reviewed by a CFA® Charterholder — one of the most rigorous credentials in the investment industry. ETF BFF is not a brokerage, a registered investment advisor, or a financial planner. Nothing on the site constitutes personalized financial advice.
At some point, someone smart told you to invest in ETFs. Maybe it was a Reddit post, a podcast, a parent, or a coworker. And they weren't wrong — a broad market ETF at 0.03% expense ratio is one of the most effective long-term wealth-building vehicles available to retail investors. But knowing that and understanding it well enough to act are two very different things.
"What even is an expense ratio? How do I know if I'm buying the right fund? Is VTI the same as VOO? How many ETFs is too many?" — real questions that deserve real answers.
The financial internet tends to do one of two things: dumb it down so much that it's useless, or bury you in jargon until you give up and do nothing. Meanwhile, the people who understand this stuff and can explain it clearly are just your friends who happen to work in finance.
ETF BFF exists to be that friend. The one who tells you that SPY and VOO track the same index but SPY costs three times more in fees — and then shows you what that costs over 30 years. Free guides, free tools, and a weekly newsletter covering ETF education that doesn't waste your time. That's the whole deal.
All guides and factsheets on this site are reviewed by an independent CFA® Charterholder for educational accuracy. The CFA designation signals that the content meets a rigorous accuracy standard — it does not make anything on this site personalized investment advice, and it does not indicate any endorsement by the CFA Institute. ETF BFF is not a registered investment advisor. See our disclaimer below.
The financial world is full of sites that say they're educational but are really just trying to sell you something. We'd rather be upfront about exactly what you're getting here.
ETF BFF is built around the questions that send people to Google at 11pm: which ETF to buy first, whether their expense ratio matters, which broker to use and why.
From ETF basics to expense ratios to building a 3-fund portfolio — clear, thorough, and jargon-free.
⚖️Put ETFs side-by-side so you can see exactly what you'd be paying and what you'd be buying.
💸See how small expense ratio differences compound into thousands of dollars over time.
🔎Filter ETFs by category, fee, assets, and strategy to find the right fit for you.
📬New guides, practical tips, and ETF explainers delivered to your inbox. No spam, ever.
🎯Answer a few questions and get a personalized starting point based on your goals and risk tolerance.
Every guide, tool, and newsletter we write passes through these filters before it goes out.
We don't have a financial product to sell, a fund family to promote, or a broker paying for placement. No piece of content here has a commercial outcome baked into it. The only question when we write something: does this leave the reader with a clearer understanding than before they read it?
We don't dumb things down — we use real fund examples. "VTI tracks 3,600 US companies at a 0.03% fee" is more useful than "diversification is good." Specific information is more actionable than general reassurance.
Good financial education shouldn't live behind a paywall. Our guides and tools are free because everyone — regardless of their starting net worth — deserves access to this information.
We'll always tell you how we make money, when we have affiliate relationships, and what we don't know. If something is an opinion, we'll say so. If the research is mixed, we'll tell you that too.
Everything on ETF BFF is for educational purposes only. None of it is personalized investment advice, a solicitation to buy or sell any security, or a recommendation tailored to your specific financial situation.
Your financial situation is unique. What works for one investor may be completely wrong for another. We'll give you the knowledge to make better decisions — but the decisions are always yours. If you need personalized guidance, please speak with a qualified financial advisor.
ETF BFF is not a registered investment advisor. All investing involves risk, including the possible loss of principal. Past performance does not guarantee future results. Content on this site is produced for general educational purposes and should not be construed as financial advice.
If something on the site is wrong, outdated, or unclear — we want to know. Same goes for topic requests, guide gaps, or tool ideas. We read everything that comes in and respond to most of it.
