Money talk can sometimes feel like a foreign language. Banks, lenders, and financial advisors toss around terms that sound complicated but are actually pretty simple once you break them down. Understanding a few key financial terms can help you make smarter decisions—whether you’re choosing a credit card, paying off debt, or planning for the future.
Why Knowing Basic Financial Terms Matters
You don’t need to be a finance expert to benefit from money knowledge. Knowing the difference between interest rates, understanding what “APR” really means, or being able to calculate your net worth can give you confidence and clarity. It also helps you avoid costly mistakes, like signing up for a loan you don’t fully understand.
Common Financial Terms Made Simple
Interest
What it means: Interest is the cost of borrowing money—or the reward for saving money. If you take out a loan, you pay interest. If you put money in a savings account, you earn interest.
Example: Borrow $1,000 with 5% yearly interest, and you’ll pay $50 in interest for that year.
APR (Annual Percentage Rate)
What it means: APR is the true cost of borrowing, including interest plus fees. It shows you the yearly cost of a loan or credit card, making it easier to compare offers.
Example: A credit card with 18% APR means you’ll pay $18 in yearly interest for every $100 you carry as a balance.
Principal
What it means: The principal is the original amount of money borrowed (or invested). Interest is charged or earned on top of it.
Example: If you borrow $10,000 for a car loan, that $10,000 is your principal.
Assets
What it means: Assets are things you own that have value, like cash, your car, your house, or investments.
Example: If you own a $200,000 home, that home is considered an asset.
Liabilities
What it means: Liabilities are debts or obligations you owe, like credit card balances, student loans, or your mortgage.
Example: If you still owe $150,000 on your mortgage, that’s a liability.
Net Worth
What it means: Net worth is the difference between what you own (assets) and what you owe (liabilities). It gives you a snapshot of your overall financial health.
Formula: Assets – Liabilities = Net Worth
Example: If you own $250,000 in assets but owe $100,000 in debts, your net worth is $150,000.
Compound Interest
What it means: Interest that builds on itself. You earn (or owe) interest on both the original principal and the interest that has already been added.
Example: If you save $1,000 with 5% annual compound interest, you’ll have $1,050 after year one. In year two, you’ll earn 5% on $1,050—not just $1,000.
Credit Score
What it means: A three-digit number (typically 300–850) that shows how reliable you are at repaying debt. Lenders use it to decide whether to give you loans and what interest rates to charge.
Example: A credit score of 750 usually qualifies you for lower loan rates than a score of 620.
Inflation
What it means: Inflation is the rise in the price of goods and services over time. It reduces the purchasing power of your money.
Example: If inflation is 3%, something that costs $100 today will cost $103 a year from now.
