Core Terms: Borrowing and Credit
APR (Annual Percentage Rate) — The yearly cost of borrowing money, expressed as a percentage. Unlike a simple interest rate, APR includes most fees, making it a more accurate measure for comparing loans or credit cards.
Credit score — A three-digit number (typically ranging from 300 to 850 in the most common scoring models) that lenders use to gauge how likely you are to repay debt. Factors like payment history, credit utilization, and account age influence the score.
Debt-to-income ratio (DTI) — Your total monthly debt payments divided by your gross monthly income. Lenders use DTI to assess whether you can handle additional debt. A lower ratio generally signals a stronger borrowing position.
Amortization — The process of paying off a loan through regular installment payments. Early payments go largely toward interest; later payments shift more toward principal. Understanding amortization helps you see the true cost of a mortgage or auto loan.
For insurance-specific borrowing and coverage terms, see our guide to deductibles, premiums, and copays.
APR
Annual Percentage Rate — the yearly cost of borrowing, including interest and most fees, expressed as a percentage. It provides a standardized basis for comparing loan and credit products.
Net Worth
Total assets minus total liabilities. A positive net worth means you own more than you owe; tracking it over time reveals the direction of your financial health.
Liquidity
The ease and speed with which an asset can be converted to cash without material loss in value. Cash and checking accounts are the most liquid assets; real estate and retirement accounts are less so.
Compound Interest
Interest earned on both the principal and previously accumulated interest. Given enough time, compounding can significantly accelerate the growth of savings or the cost of debt.
Amortization
The structured repayment of a loan through scheduled installments. Each payment reduces the outstanding balance, though early payments primarily cover interest rather than principal.
Debt-to-Income Ratio
Monthly debt obligations divided by gross monthly income, expressed as a percentage. Lenders use it to evaluate a borrower's capacity to manage additional debt repayment.
Diversification
The practice of distributing investments across multiple asset types or sectors to reduce exposure to any single risk. Diversification can limit losses but does not guarantee positive returns.
Tax-Advantaged Account
An investment or savings account that provides a federal tax benefit. Examples include traditional and Roth IRAs and employer-sponsored 401(k) plans, each with distinct contribution and withdrawal rules.
Core Terms: Saving, Investing, and Building Wealth
Net worth — The difference between everything you own (assets) and everything you owe (liabilities). It is one of the most useful snapshots of financial health over time.
Liquidity — How quickly and easily an asset can be converted to cash without significant loss of value. A checking account is highly liquid; real estate is not.
Compound interest — Interest calculated on both the original principal and accumulated interest. Over time, this creates exponential growth. For a deeper look at how compounding builds long-term wealth, see our article on compound interest and the math behind it.
Diversification — Spreading investments across different asset types, sectors, or geographies to reduce the impact of any single loss. It does not eliminate risk but can lower overall portfolio volatility. Our guide to stocks, bonds, and cash explains how asset classes behave differently.
Tax-advantaged account — A savings or investment account that offers a tax benefit. Common examples include 401(k) plans and IRAs. Contributions may reduce taxable income now (traditional) or allow tax-free withdrawals later (Roth). Ready to go further? Explore our Investing Basics hub for foundational concepts.
~34%
Americans with no retirement savings

3–6 months

Financial educators broadly suggest this range, though the right target depends on income stability and individual expenses.
~57%
Adults who check their credit score regularly
Consumer Financial Protection Bureau data indicates the majority of U.S. adults now monitor their credit scores at least occasionally.
Terms That Cut Across Every Financial Decision
Emergency fund — Liquid savings set aside specifically for unexpected expenses or income loss. Financial educators commonly describe three to six months of essential living expenses as a general benchmark, though the right amount depends on individual circumstances.
Inflation — The rate at which the general level of prices rises over time, eroding purchasing power. A dollar today buys less than a dollar did ten years ago. Inflation directly affects the real return on savings and investments.
Risk tolerance — A person's willingness and ability to endure fluctuations in the value of their investments. It reflects both emotional comfort with uncertainty and objective financial capacity to absorb losses without derailing long-term goals.
