Starting early matters more than the amount you start with.","2026-07-26",[14,15],"compound interest","investing basics","\nPeople often call compound interest one of the strongest forces in personal finance. The math behind why is simple.\n\n## Simple interest vs. compound interest\n\nWith **simple interest**, you earn interest only on your original amount. With **compound interest**, you earn interest on your original amount *plus* all the interest you already accumulated. Over short periods the difference looks small. Over many years it grows large.\n\n## A worked example\n\nSay you invest $1,000 at a 7% annual return, and never add another dollar:\n\n- **Year 1**: $1,000 grows to $1,070\n- **Year 10**: roughly $1,967\n- **Year 20**: roughly $3,870\n- **Year 30**: roughly $7,612\n\nNotice the growth from year 20 to 30 ($3,742) is larger than the entire first 20 years combined. That's compounding: growth building on growth.\n\n## Why starting early matters more than the amount\n\nBecause compounding needs time to build, a smaller amount invested early often ends up ahead of a larger amount invested later. Someone who invests $200\u002Fmonth starting at 25 ends up with more at retirement than someone investing $400\u002Fmonth starting at 35, purely because of the extra years of compounding, even though the second person put in more money overall.\n\n## The other side: compounding debt\n\nThe same math works against you with debt that charges compound interest, like many credit cards. Unpaid interest gets added to your balance, and then you pay interest on that interest too. That's why credit card debt grows faster than expected.\n\nReal investments fluctuate and lose value during down periods, unlike the fixed 7% return used above for simplicity. This page explains how the math works. It isn't a projection or a recommendation for any specific return or investment.\n",[18,28,39],{"slug":19,"pillar":6,"locale":7,"frontmatter":20,"content":27},"etfs-explained",{"title":21,"description":22,"tldr":23,"updatedAt":24,"tags":25},"ETFs Explained: How They Work and How to Buy One","What an ETF is, how it differs from a mutual fund, what it costs to hold one, and what you need to buy your first one.","An ETF (exchange-traded fund) holds a basket of investments, like a stock or a mutual fund, and trades on an exchange throughout the day. Most charge a small annual expense ratio and no separate purchase fee at major brokers. You need a brokerage or investment account to buy one.","2026-08-08",[26,15],"ETFs","\nETF stands for exchange-traded fund. It holds a basket of investments, similar to a mutual fund, but trades on an exchange the same way a share of stock does.\n\n## What makes it \"exchange-traded\"\n\nA traditional mutual fund prices once a day, after the market closes, and you buy or sell at that single price. An ETF trades throughout the market's open hours at a price that moves in real time, the same as a stock. You place an order through a brokerage account, and it fills at whatever the market price is at that moment, not at a single end-of-day number.\n\n## What's inside one\n\nAn ETF's holdings depend entirely on what it's built to track. Many ETFs are built the same way as the index funds covered in [what is an index fund](\u002Flearn\u002Fwhat-is-an-index-fund): a broad basket of stocks or bonds tracking a market index. Others track a narrower slice, like a single sector, a specific country, or a commodity. The name and the fund's own fact sheet tell you what's inside. Two ETFs with similar-sounding names sometimes hold entirely different things.\n\n## What it costs to hold one\n\nEvery ETF charges an expense ratio, an annual fee taken as a small percentage of your investment, disclosed in the fund's prospectus. A broad, simple ETF typically charges less than a narrow or specialized one. Most major brokers no longer charge a separate commission to buy or sell ETF shares, though a small gap between the buy and sell price (the bid-ask spread) still exists on every trade.\n\n## What you need to buy one\n\nBuying an ETF requires a brokerage or investment account, not a special ETF-specific account. See [investment account options](\u002Finvest\u002Finvestment-accounts-comparison) or a [robo-advisor](\u002Finvest\u002Frobo-advisors-comparison) if you'd rather have a fund selection handled for you within a chosen risk level. Once the account is funded, you search for the ETF by its ticker symbol and place an order like you would for a stock.\n\n## ETF or mutual fund: does the difference matter\n\nFor a long-term investor who isn't trading during the day, the practical difference between a broad-market ETF and an equivalent index mutual fund is often small. It matters more if you want to trade during market hours, want a lower minimum investment (many ETFs let you buy a single share, some mutual funds require a minimum), or care about the tax treatment in your specific account type.\n\nNothing above recommends a specific ETF, sector, or provider. Check the expense ratio, what the fund holds, and how it fits your own timeline before investing.\n",{"slug":29,"pillar":6,"locale":7,"frontmatter":30,"content":38},"investing-basics-beginners",{"title":31,"description":32,"tldr":33,"updatedAt":12,"tags":34},"Investing Basics: What Stocks, Bonds, and Index Funds Are","A plain-English explanation of the main building blocks of investing: stocks, bonds, and index funds, and how they differ in risk and purpose.","Stocks are small ownership stakes in a company. Bonds are loans you make to a government or company for interest. Index funds bundle many stocks or bonds together so you don't bet on only one. This explains the basics. It doesn't recommend any specific investment.",[15,35,36,37],"stocks","bonds","index funds","\nBefore comparing specific investments, it helps to understand the basic building blocks.\n\n## Stocks: owning a small piece of a company\n\nA stock is a share of ownership in a company. If the company grows and becomes more valuable, the value of your share rises. If it struggles, the value falls, including to zero in the worst case. Investors generally consider stocks higher risk and higher potential return than bonds, because a company's future is uncertain.\n\n## Bonds: lending money for interest\n\nA bond is a loan. You lend money to a government or a company, and in return they agree to pay you interest over time and return your original amount (the \"principal\") at the end of a set period. Investors generally consider bonds lower risk than stocks, but bonds also usually offer lower long-term returns.\n\n## Index funds: many investments in one\n\nAn index fund pools money from many investors to buy a broad basket of stocks or bonds that track a market index, like a country's largest companies. Instead of betting on one company doing well, you get a small slice of many companies at once, which spreads out the risk of any single company doing poorly.\n\n## Why risk and time horizon matter together\n\nEvery one of these carries some risk of losing value, especially in the short term. Money you need soon, within a couple of years, generally belongs in lower-risk places. Money you won't touch for many years has more time to recover from short-term drops. Your own timeline, other savings, and comfort with risk all matter here, since none of this is personal advice.\n\nOnce these building blocks feel familiar, [angel investing, venture capital, and private equity explained](\u002Finvest\u002Fangel-investing-vs-venture-capital-vs-private-equity) covers the private-market layer above public stocks, bonds, and index funds.\n\nNothing above suggests buying any specific stock, bond, or fund. Before investing real money, learn how fees, taxes, and diversification work, and talk to a licensed financial professional about your specific situation.\n",{"slug":40,"pillar":41,"locale":7,"frontmatter":42,"content":49},"what-is-an-index-fund","learn",{"title":43,"description":44,"tldr":45,"updatedAt":46,"tags":47},"What Is an Index Fund?","Index funds explained simply: how they track a market instead of picking individual winners, and why the approach keeps fees low.","An index fund holds a broad basket of investments built to track a market index, instead of a manager picking individual stocks. That structure usually means lower fees and broad diversification in one investment.","2026-07-27",[37,48,15],"glossary","\nAn **index fund** is a fund built to match the performance of a specific market index, such as a benchmark tracking a country's largest companies, instead of trying to beat the market by picking individual winners.\n\n## How it works\n\nAn index defines a rule. For example: \"the largest companies listed on a given exchange.\" An index fund buys a basket of investments that mirrors that rule closely, so its performance moves with the index rather than one manager's stock picks.\n\n## Why fees stay low\n\nAn index fund follows a fixed, rules-based approach instead of paying analysts to research and pick investments. That keeps costs down compared to an actively managed fund. Fees show up as an annual percentage of your investment, called the expense ratio. A small difference in that percentage compounds into a large gap over decades.\n\n## Why average performance still works\n\nAn index fund does not try to beat the market. It tries to match it. Over long periods, a large share of actively managed funds have underperformed their benchmark index after fees. Past patterns do not guarantee future results, but this is why index funds get discussed as a simple, low-cost building block.\n\n## The link to diversification\n\nAn index fund holds many underlying investments at once, which spreads out the risk of any single company doing poorly. See [what is diversification](\u002Flearn\u002Fwhat-is-diversification) for more on why that matters.\n\nNothing here recommends a specific index fund, provider, or index. Fees, taxes, and the index tracked all vary and are worth checking before you invest.\n",{"data":51,"body":54,"excerpt":-1,"toc":186},{"title":52,"description":53},"","People often call compound interest one of the strongest forces in personal finance.
