Each unit of currency buys a little less than it used to.\n\n## A simple example\n\nInflation at 4% in a year turns a $100 purchase into a $104 purchase by year end. Your $100 bill did not shrink. What it buys did.\n\n## Why this matters for cash savings\n\nMoney sitting in a low-interest account loses value over time if its rate falls below inflation. $10,000 earning 0.5% interest while inflation runs at 4% loses about 3.5% of its purchasing power every year, even as the account balance grows.\n\n## Why this matters for investing\n\nThis is a core reason long-term money gets invested instead of parked in cash. Stocks have historically outpaced inflation over long periods. Cash has not. That is a historical pattern, not a guarantee. See our [investing basics](\u002Finvest\u002Finvesting-basics-beginners) guide for the tradeoffs.\n\n## Where to see the effect\n\nOur [compound interest calculator](\u002Ftools\u002Fcompound-interest) shows growth in nominal terms, not adjusted for inflation.

Retirement Accounts Explained","401(k)s and IRAs explained in plain English: what makes a retirement account different from a regular investment account, and how the main types differ.","A 401(k) and an IRA are tax-advantaged accounts for retirement savings, not investments themselves. They hold investments and change how those investments get taxed. A 401(k) comes through an employer. An IRA gets opened individually.",[25,26,15,27],"401k","IRA","retirement","\nA **401(k)** and an **IRA (Individual Retirement Account)** hold investments for retirement, with tax rules that differ from a regular brokerage account. Neither is an investment on its own. Think of them as a container that holds investments like funds or stocks.\n\n## 401(k): through an employer\n\nAn employer sponsors a 401(k), sets up the plan, and often picks a limited menu of investment options. Many employers add a matching contribution, putting in additional money based on how much you contribute, up to a limit. That match works like part of your compensation when you use it.\n\n## IRA: opened on your own\n\nYou open an IRA individually through a brokerage, independent of any employer, and it generally offers a wider range of investment choices than a typical 401(k). Anyone with eligible income qualifies to open one, whether or not their employer offers a 401(k).\n\n## Traditional vs. Roth: the tax tradeoff\n\nBoth 401(k)s and IRAs commonly come in two tax versions.\n\n- **Traditional.** Contributions reduce your taxable income now. Withdrawals in retirement get taxed as income.\n- **Roth.** Contributions do not reduce your taxable income now. Qualified withdrawals in retirement come out tax-free.\n\nThe better choice between the two depends on your current tax rate against your expected tax rate in retirement. That calculation is personal, not one-size-fits-all.\n\n## Check the employer match first\n\nBefore optimizing between account types, check your employer's 401(k) match. Leaving matching contributions unclaimed means leaving part of your compensation unclaimed, a foundational fact worth checking before other retirement decisions.\n\nOnce money sits in one of these accounts, the same investment questions apply: how much to contribute, what to invest in, and when you retire. Our [investing basics](\u002Finvest\u002Finvesting-basics-beginners) guide and [retirement calculator](\u002Ftools\u002Fretirement) cover those next steps.\n\nContribution limits, income limits, and tax rules for these accounts change over time and depend on your specific situation. Talk to a licensed tax or financial professional about your circumstances.\n",{"slug":30,"pillar":6,"locale":7,"frontmatter":31,"content":38},"what-is-an-index-fund",{"title":32,"description":33,"tldr":34,"updatedAt":12,"tags":35},"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.",[36,15,37],"index funds","investing basics","\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",{"slug":40,"pillar":6,"locale":7,"frontmatter":41,"content":49},"what-is-apr",{"title":42,"description":43,"tldr":44,"updatedAt":45,"tags":46},"What Is APR? Annual Percentage Rate Explained","APR explained in plain English: how it differs from a simple interest rate, and why it's the number to use when comparing loans or credit cards.","APR (Annual Percentage Rate) is the yearly cost of borrowing money, including most fees, expressed as a percentage. It's usually a more complete number than the plain interest rate, which is why it's the standard for comparing loan or credit card offers.","2026-07-26",[47,15,48],"APR","credit","\n**APR (Annual Percentage Rate)** is the yearly cost of borrowing money, expressed as a percentage, including most of the fees involved, not only the base interest rate.\n\n## APR vs. interest rate\n\nThe interest rate is only part of the cost of a loan. APR bundles in most upfront fees, like an origination fee, and spreads their cost over the loan, giving you a more complete yearly cost figure. Two loans with the same interest rate have different APRs if one charges more in fees.\n\n## Why APR is the number to compare\n\nBecause APR standardizes fees and interest into one yearly percentage, it's generally the most reliable single number for comparing offers from different lenders, more reliable than comparing interest rates or monthly payments alone.\n\n## Where you'll see it\n\n- Credit cards (often with a range, since your specific rate depends on your creditworthiness)\n- Personal loans\n- Auto loans\n- Mortgages, where lenders must disclose it alongside the interest rate\n\n## A quick way to use it\n\nWhen comparing two offers for a similar loan amount and term, the one with the lower APR is generally the cheaper option overall. Always double check the term length matches, since a lower APR over a much longer term still costs more in total interest.\n",{"data":51,"body":54,"excerpt":-1,"toc":137},{"title":52,"description":53},"","Inflation is the rate at which prices for goods and services rise over time.
