The basics Saving Debt & credit Investing Retirement Real estate

The basics

Assets: Things you own that have monetary value — cash, savings, investments, a home, a car. Assets that put money in your pocket (like investments) are what build wealth.
Budget: A plan for how your income is divided between spending, saving, and paying off debt. A common starting framework is 50/30/20 — 50% needs, 30% wants, 20% saving.
Cash flow: The money coming in versus going out over a period. Positive cash flow (more in than out) is what lets you save and invest; negative cash flow means you're drawing down or borrowing.
Emergency fund: Money set aside for unexpected expenses — a job loss, medical bill, or car repair — usually three to six months of essential expenses, kept somewhere safe and easy to reach.
Liabilities: Everything you owe — mortgages, car loans, student loans, credit card balances. Reducing liabilities is one of the two levers (along with growing assets) that raises your net worth.
Liquidity: How quickly an asset can be turned into cash without losing value. Cash is fully liquid; a home is not. Your emergency fund should stay in liquid, low-risk accounts.
Net worth: Everything you own (assets) minus everything you owe (debts). It's the single clearest snapshot of your financial position, and the number to watch grow over time.

Saving

APY (annual percentage yield): The real annual return on savings, including the effect of compounding. When comparing savings accounts, compare APY — it reflects what you actually earn in a year.
High-yield savings account (HYSA): A savings account that pays a much higher interest rate than a typical bank savings account, often several times more. A common home for an emergency fund or short-term goal.
Sinking fund: Money you set aside a little at a time for a known future expense — holidays, insurance, a new phone — so it doesn't hit your budget or your credit card all at once.

Debt & credit

APR (annual percentage rate): The yearly cost of borrowing, shown as a percentage. On credit cards it's the interest you pay on balances you carry; a lower APR means debt costs you less.
Credit score: A number (commonly 300–850) that lenders use to estimate how reliably you repay debt. It's driven mostly by payment history and how much of your available credit you use.
Credit utilization: The share of your available credit you're using. Keeping it low (often under 30%, lower is better) is one of the fastest ways to help your credit score.
Debt avalanche: A payoff strategy where you attack the highest interest rate first (while paying minimums on the rest). It saves the most money in interest, though wins come slower than the snowball.
Debt snowball: A payoff strategy where you attack the smallest balance first (while paying minimums on the rest) for quick, motivating wins, then roll that payment into the next debt.
Minimum payment: The smallest amount a lender requires each month to keep an account in good standing. Paying only the minimum on high-interest debt can stretch payoff over many years.
Secured vs. unsecured debt: Secured debt is backed by an asset the lender can take if you don't pay (a mortgage, an auto loan). Unsecured debt isn't (most credit cards, personal loans) and usually carries higher rates.

Investing

Asset allocation: How you divide investments among types — like stocks, bonds, and cash. It's the biggest driver of both your expected return and how bumpy the ride is, and it shifts as your goals and age change.
Bull vs. bear market: A bull market is a sustained rise in prices; a bear market is a sustained fall (often defined as 20%+ down). Both are normal parts of a long investing life.
Capital gains: The profit when you sell an investment for more than you paid. Held over a year, gains are usually taxed at lower long-term rates; sold sooner, they're taxed as ordinary income.
Compound interest: Earning returns on both your original money and on the returns it has already earned. Over long periods it's the main engine of investment growth — which is why starting early matters so much.
Diversification: Spreading your money across many investments so no single one can sink you. It reduces risk without necessarily reducing long-term return — the closest thing to a free lunch in investing.
Dividend: A share of a company's profit paid out to shareholders, usually in cash. Reinvesting dividends buys more shares and adds to the compounding effect over time.
Dollar-cost averaging: Investing a fixed amount on a regular schedule regardless of price. You buy more shares when prices are low and fewer when high, and you avoid trying to time the market.
ETF (exchange-traded fund): A basket of investments that trades like a single stock throughout the day. Many index funds come in ETF form, offering low costs and easy diversification.
Expense ratio: The yearly fee a fund charges, as a percentage of your money. It looks tiny (e.g. 0.03% vs 1%) but compounds against you for decades — lower is almost always better.
Index fund: A fund that holds every company in a market index (like the S&P 500) instead of trying to pick winners. Low cost and broadly diversified, it's a common core holding for long-term investors.
Risk tolerance: How much drop in value you can handle — financially and emotionally — without abandoning your plan. It should match your time horizon: more time usually means you can take more risk.

Retirement

401(k): A retirement account offered through an employer, often with a matching contribution. Money typically goes in pre-tax, lowering today's taxable income, and grows tax-deferred until withdrawal.
Employer match: When your employer adds money to your 401(k) based on what you contribute — for example, matching the first few percent of your pay. It's an immediate, guaranteed return, so it's usually worth capturing first.
IRA (individual retirement account): A retirement account you open on your own, outside an employer. It comes in two main flavors — Traditional and Roth — that differ mainly in when you pay taxes.
Roth IRA: A retirement account funded with money you've already paid tax on. It then grows and can be withdrawn in retirement completely tax-free — powerful when you have decades to compound.
Tax-advantaged account: An account that gives a tax break for saving toward a goal — like a 401(k), IRA, or HSA. Using these before a regular brokerage account is one of the highest-value moves in investing.
Traditional IRA: A retirement account where contributions may lower your taxable income now, and you pay tax later when you withdraw in retirement. The mirror image of a Roth.
Vesting: The schedule by which employer contributions become fully yours. Your own contributions are always yours; the match may require staying a few years before you keep all of it.

Real estate

Cap rate: A rental property's yearly net operating income divided by its price, as a percentage. A quick way to compare income properties before digging into the full numbers.
Cash-on-cash return: The yearly cash flow from a rental divided by the actual cash you put in (down payment and costs). It shows what your invested money is really earning, separate from the property's total value.
HELOC (home equity line of credit): A revolving line of credit secured by your home equity, that you can draw from as needed. Flexible and often lower-rate than unsecured debt, but your home is the collateral.
Home equity: The part of your home you actually own — its market value minus what you still owe on the mortgage. It grows as you pay down the loan and as the home appreciates.
