Your investing BFF.
Free ETF education built around the questions real investors ask: which fund, which broker, what does this fee actually cost me over 30 years. No sales pitch, no product placement.
What is ETF BFF?
ETF BFF (etfbff.com) launched in 2026, but the idea had been sitting around for five years before that. It came from 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 written by the ETF BFF editorial team, based on issuer data and publicly available fund materials. ETF BFF is not a brokerage, a registered investment advisor, or a financial planner. Nothing on the site constitutes personalized financial advice.
Because "just buy index funds" isn't actually helpful 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?" These are 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, 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 written by the ETF BFF editorial team, based on issuer data and publicly available fund materials. Nothing on this site is personalized investment advice. ETF BFF is not a registered investment advisor. See our disclaimer below.

The principles behind everything we publish.
Every guide, tool, and newsletter we write passes through these filters before it goes out.
🎓 Education first, always
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?
💬 Specificity over simplicity
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.
🔓 Free and open access
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.
🪟 Radical transparency
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.
Editorial standards and review process.
The checks every piece of content clears before, and after, it goes live.
📚 Research from primary sources
Fund facts come from the source: SEC filings and prospectuses, issuer fact sheets, and the funds' own holdings data. Tax and regulatory points cite the underlying statute or IRS guidance, not a summary of a summary. Where we state a number, it traces back to a document you could open yourself.
🎓 Based on primary sources
Guides are based on issuer data and publicly available fund materials. The focus is transparent sourcing and plain-English explanations, not sales pitches or product placement.
🔄 Live data, clearly dated
Factsheet figures (expense ratios, holdings, yields) are refreshed from an automated daily pipeline and shown "as of" a date. Guides carry a visible last-updated date and are revised as funds, fees, and rules change. If a number is approximate or historical, we say so.
✅ Sourcing and corrections
Our content is based on issuer data and publicly available fund materials, and we fix errors fast. Spot something wrong? Email hello@etfbff.com and we will correct it, and note the change where it is material. Accuracy over ego, every time.
💵 How we make money
ETF BFF is free to read. Some links to brokerages are affiliate links, meaning we may earn a commission if you open an account, at no cost to you. That relationship never buys a recommendation, a ranking, or a kind word. We do not sell funds, take payment for placement, or manage anyone's money.
🧩 Independence
We have no fund family to promote and no product of our own to sell. When the honest answer is "just buy a broad index fund and stop tinkering," that is what we write, even when a more complicated answer would be easier to monetize.
Not financial advice, and we mean it.
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.
