Financial Glossary

Plain-English definitions for financial terms you encounter in our calculators.

A

Amortization

The process of paying off a loan through regular scheduled payments covering both principal and interest. Early payments are mostly interest; later ones mostly principal.

Annual Percentage Rate (APR)

The yearly cost of borrowing money, expressed as a percentage, including fees and interest. Higher APR = more expensive loan.

Asset Allocation

Strategy of dividing investments among different asset categories (stocks, bonds, cash, real estate) to balance risk and reward.

B

Bear Market

A period when security prices fall 20% or more from recent highs. Opposite of a bull market. Associated with investor pessimism.

Bull Market

A period of rising security prices, typically defined as a 20%+ increase. Associated with investor confidence and economic growth.

C

Capital Gains

Profit from selling an asset for more than its purchase price. Short-term (held <1 year) taxed as income; long-term taxed at lower rates.

Compound Interest

Interest calculated on both the principal AND accumulated prior interest. Causes exponential growth — the basis of long-term wealth building.

D

Diversification

Spreading investments across different assets, sectors, and geographies to reduce risk. If one investment falls, others may rise.

Dollar-Cost Averaging

Investing a fixed amount regularly regardless of price. Reduces the impact of volatility by buying more shares when prices are low.

E

Emergency Fund

Liquid savings covering 3–6 months of living expenses, kept for unexpected costs or job loss. Keep in a high-yield savings account.

ETF (Exchange-Traded Fund)

A basket of securities that trades on an exchange like a stock. Offers instant diversification at low cost. Often tracks an index.

I

Index Fund

A passively managed fund tracking a market index (like the S&P 500). Low fees, broad diversification, historically beats most active funds.

Inflation

The general rise in prices over time, reducing purchasing power. $100 today buys less than $100 in 10 years.

L

Liquidity

How quickly and easily an asset can be converted to cash without significant value loss. Cash is most liquid; real estate is less so.

N

Net Worth

Total assets minus total liabilities. Your actual financial position. Regular tracking reveals whether you&apos;re building or losing wealth.

P

Portfolio

The complete collection of investments owned by an individual. A well-constructed portfolio balances risk tolerance with growth goals.

Principal

The original amount borrowed or invested, before any interest is added or subtracted. Loan payments reduce the principal balance.

R

Return on Investment (ROI)

The gain or loss from an investment relative to its cost, expressed as a percentage. Formula: (Final - Initial) / Initial × 100.

Risk Tolerance

The degree of investment value fluctuation you're willing to accept. Higher risk tolerance allows more aggressive (potentially higher-return) investments.

Y

Yield

Income generated by an investment (dividends, interest) as a percentage of its price. A bond paying $50/year on a $1,000 value has a 5% yield.
