Financial Terms Glossary - 50+ Terms Explained

This glossary defines 50+ common financial terms you will encounter when using our financial calculators and reading financial content. Terms are organized alphabetically with clear definitions and examples.

A

Amortization

The process of paying off a loan through fixed periodic payments that cover both principal and interest. Early payments are mostly interest, later payments are mostly principal.

Annual Percentage Rate (APR)

The annual cost of borrowing, including interest and certain fees, expressed as a percentage. APR provides a standardized way to compare loan offers.

Annual Percentage Yield (APY)

The effective annual rate of return after compounding. APY is higher than APR for the same nominal rate when compounding occurs more than once per year.

Asset

Anything of value that you own. Assets include cash, investments, real estate, vehicles, and personal property. Total assets minus total liabilities equals net worth.

B

Balance

The remaining amount owed on a loan or the current amount in an account. Loan balances decrease as you make payments, account balances change with deposits and withdrawals.

Bond

A debt investment where you lend money to an entity (government or corporation) that pays periodic interest and returns the principal at maturity.

C

Capital Gain

Profit from selling an asset for more than its purchase price. Capital gains are taxed at preferential rates in many jurisdictions if the asset was held for more than one year.

Collateral

Property pledged as security for a loan. If you default, the lender can seize the collateral. Mortgages use the home as collateral, auto loans use the vehicle.

Compound Interest

Interest calculated on both the principal and accumulated interest from previous periods. Compound interest causes investments to grow exponentially over time.

Credit Score

A numerical representation of creditworthiness, typically ranging from 300 to 850. Higher scores indicate lower risk and qualify for better loan terms.

D

Debt-to-Income Ratio

Monthly debt payments divided by monthly gross income, expressed as a percentage. Lenders prefer DTI below 36% for mortgage approval.

Default

Failure to repay a loan according to the agreed terms. Default can result in asset seizure, credit score damage, and legal action.

Down Payment

An upfront payment made when purchasing an asset, reducing the loan amount needed. Down payments of 20% or more on homes eliminate PMI.

E

EMI (Equated Monthly Installment)

The fixed monthly payment required to repay a loan over a specified term. EMI includes both principal and interest components.

Equity

The portion of an asset you own outright, calculated as asset value minus loan balance. Home equity increases as you pay down the mortgage and as home value appreciates.

F

FICO Score

The most widely used credit score in the US, ranging from 300 to 850. FICO scores are based on payment history, credit utilization, length of credit history, credit mix, and new credit.

Fixed Rate

An interest rate that remains constant for the entire loan term. Fixed rates provide payment predictability but may start higher than variable rates.

Floating Rate

An interest rate that changes periodically based on a reference rate. Floating rates start lower than fixed rates but carry the risk of increasing.

I

Inflation

The rate at which prices increase over time, reducing purchasing power. Inflation erodes the real value of savings and investments.

Interest

The cost of borrowing money or the return on lending money, expressed as a percentage of the principal.

L

Leverage

Using borrowed money to increase investment returns. Leverage amplifies both gains and losses.

Liquidity

How easily an asset can be converted to cash. Cash is perfectly liquid, real estate is illiquid, stocks are moderately liquid.

Loan Term

The period over which a loan is repaid. Longer terms mean lower monthly payments but more total interest.

M

Mortgage

A loan used to purchase real estate, where the property serves as collateral. Mortgages typically have 15 or 30-year terms.

Mutual Fund

An investment vehicle that pools money from many investors to buy a diversified portfolio of stocks, bonds, or other securities.

N

Net Worth

Total assets minus total liabilities. Net worth is a key measure of financial position.

Nominal Return

Investment return before adjusting for inflation. Real return is nominal return minus inflation.

P

PMI (Private Mortgage Insurance)

Insurance required when down payment is less than 20% of home value. PMI protects the lender and costs 0.3-1.5% of loan amount annually.

Principal

The original amount borrowed or invested, not including interest.

R

Refinancing

Replacing an existing loan with a new loan, typically to get a lower interest rate, different term, or cash out equity.

Return on Investment (ROI)

Profit from an investment divided by the cost of the investment, expressed as a percentage.

S

Savings Rate

Percentage of income saved or invested. Higher savings rates lead to faster wealth accumulation and earlier financial independence.

Simple Interest

Interest calculated only on the principal, not on accumulated interest. Simple interest grows linearly, compound interest grows exponentially.

T

Tax-Advantaged Account

Investment account with tax benefits, such as 401(k), IRA, or HSA. Tax advantages include tax-deductible contributions, tax-free growth, or tax-free withdrawals.

Tenure

The duration of a loan. Longer tenure means lower monthly payments but more total interest.
