What's your net worth? 10 financial terms everybody should understand
Published on July 31, 2026
Some people believe that, unless you work in the world of finance, there is no need to understand financial terms and concepts. Well, nothing could be further from the truth. Finance is a core part of society, and financial literacy is important for everyone. At the same time, some of these terms are thrown around without fully understanding their meaning. What is a principal? Is compound interest different from normal interest? What is a person’s net worth? Here are 10 financial concepts that everyone should know.
Principal
Whether you are investing a sum of money or taking a loan, there is an initial sum of money involved. The principal is the initial amount of money that you invest or borrow. It does not include any interest, fees, or future earnings, and it’s used as a base to calculate the interest that will be added to a loan and the returns from an investment.
Compound Interest
We commonly understand interest as the cost we pay for borrowing money, often calculated as a percentage of the principal amount. That is ‘simple interest’, but what about ‘compound interest’? Any accumulated interest from previous periods generates its own interest as well, so compound interest is the sum of the interest on the principal amount and the accumulated interest.
Net Worth
We often hear the media discuss the net worth of celebrities, politicians, and other public figures, but can the worth of a person be calculated? When it comes to finance, it can, and it follows a very simple formula: the value of all your assets minus any money you owe. This simple but effective calculation is a good way to check how healthy your finances are at any point in time.
Annual Percentage Rate (APR)
Paying a loan is never as simple as adding interest to the initial amount. In most cases, there are different fees involved, which means that you might owe more than you think. The Annual Percentage Rate or APR will give you the true cost of a loan —initial amount, interest, and any additional fees— represented as a percentage. With the APR, you can also compare loans to see which one offers better options.
Dividend
If you own shares in a company, you will receive dividends, a portion of the profit made by the company. How do dividends work? Paid regularly, often quarterly, its value is decided by the company’s board of directors, who will determine an amount to be paid per share. The more shares you have, the more dividends you will receive.
Amortization
When taking out a loan, we are assuming that we will pay it over a period of time. This is called amortization. While the amortization of a loan gives us the possibility of paying a large sum back in regular smaller installments, it also involves interest (both simple and compound) and fees added to the principal amount.
Liquidity
An asset is an item of value, and this includes cash, but also other valuable things such as objects, properties, bonds, shares, etc. Liquidity refers to how quickly an asset can be turned into cash without affecting its value, which in turn tells us how quickly we could access funds to cover any payment or debt.
Escrow
If you ever looked into buying a home, you might have heard the term ‘escrow’. An escrow is a legal arrangement where a third, neutral party temporarily controls the funds of a transaction, releasing them once the contract’s terms have been fulfilled. This helps prevent fraud, reduce financial risks, guarantee fairness, and ensure that neither party takes advantage of the other.
Delinquency
If you are a financial delinquent, you might be in trouble, but not in the way you imagine. When taking on a loan, you assume a responsibility to pay it back. If you fail to do so, or fall behind in your payments, you become a ‘delinquent’. While delinquency is temporary, it will hurt your credit score and can eventually turn into default, which allows the lender to take action against you.
Liability
We often use the word liability to describe a disadvantage or something that could cause difficulties. In its financial sense, liabilities refer to a responsibility or obligation we assume, such as paying back a loan. In this sense, liabilities —money we owe— are opposite to assets —money we possess.
