From college classrooms to your first paycheck and beyond, you'll hear a lot of financial terms thrown around. APR, DTI, net pay, principal—it can sometimes feel like a different language. Our guide breaks down 12 common terms, so your finances are easier to understand and less intimidating
Fixed costs vs. variable costs
Budgeting is a crucial part of adulting, and a lot of factors come into play. To fully understand how to build your monthly budget, it’s important to learn the types of expenses that shape it.
Fixed costs are your expenses that stay consistent from month to month. Examples include rent, loan payments and tuition. Although these costs may increase over time, they generally remain predictable from one month to the next.
However, variable costs can change each month. Some examples of these are utilities, gas, food and entertainment.
Knowing the difference between fixed and variable costs makes it easier to build a budget, track spending and identify areas where you may be able to cut back.
Gross pay vs. net pay
Starting your first job? You’re probably excited to make some money. Before that first paycheck arrives, it’s a good idea to know the difference between gross pay and net pay.
Gross pay is the total amount an employee earns before any deductions are removed. This doesn’t account for taxes, benefits, retirement contributions or other withholdings.
Net pay is the actual amount you’ll see in your bank account, after those deductions.
In short, gross pay is the total amount you earn, while net pay is the amount you take home.
Credit score
Whether you're applying for your first credit card, buying a car or renting your first apartment, your credit score can have a bigger impact than you might think.
Think of your credit score as a snapshot of how you've managed borrowed money. It's a three-digit number that lenders use when deciding whether to approve you for a loan or credit card and what interest rate to offer.
Making payments on time and borrowing responsibly helps you maintain a good credit score and opens doors to future opportunities.
Debt-to-income ratio (DTI)
DTI is the percentage of your income that goes towards debt payments. Lenders use it to understand how much of your income is already committed to expenses like loans and credit card payments.
To calculate your DTI, add up your monthly debt payments, divide that total by your gross monthly income and multiply by 100.
You ultimately want to have a lower DTI because it shows that a smaller portion of your income is going toward existing debt, which may improve your chances of qualifying for a new loan.
Net worth
Along with DTI, your net worth is another way to measure your financial health. Net worth is the difference between what you own (your assets) and what you owe (your liabilities). Assets may include savings, investments and other valuable property you own. Liabilities include debts such as student loans, credit card balances and auto loans.
A positive net worth means your assets exceed your debts, while a negative net worth means you owe more than you own.
Interest rate
Whether you're taking out a student loan or growing your savings, interest rates play a big role in how your money works.
When you borrow money, the lender typically charges interest as the cost of borrowing. The higher the interest rate, the more you'll usually pay over time.
However, when you keep money in a savings account, the financial institution pays interest to you as a reward, helping your balance grow.
Understanding interest rates allows you to compare loan options, estimate borrowing costs and make the most of your savings.
Compound interest vs. simple interest
Interest isn't always calculated the same way. One of the biggest differences is whether you're dealing with simple interest or compound interest.
Simple interest is calculated only on the principal—or the baseline amount of money borrowed or invested. This is considered simple because the amount of interest will stay the same.
In comparison, compound interest is calculated on the principal and previously earned interest. In other words, your money can start earning interest on its interest.
If you're saving for the future, compound interest is a powerful tool because it helps your money grow over time. That's one reason you should start saving early, even with small amounts.
Annual percentage rate (APR) vs. annual percentage yield (APY)
APR and APY may look similar, but they serve two very different purposes.
APR is the annual cost of borrowing money from a financial institution. You’ll typically see it associated with products like credit cards, auto loans and mortgages. In general, a lower APR means you'll pay less interest over the life of the loan.
APY measures how much you can earn on money deposited in a savings account, certificate of other interest-bearing account. APY takes compounding interest into account, helping you understand how much your savings could grow over time. A higher APY means your savings has more potential to grow.
Put simply: When borrowing, look for a lower APR. When saving, look for a higher APY.
Minimum payment
If you have a credit card, you might have noticed there’s an option for a minimum payment. This is the smallest amount you can pay by the due date to keep your account in good standing.
This payment will help you avoid late fees and negative marks. However, if you don’t pay back the remaining balance in a timely manner you may still accrue interest. Paying more than the minimum when possible allows you to reduce interest charges and pay off debt faster.
Principal
Did you take out a student loan for college? One of the first borrowing terms you'll come across is principal, which is the base amount of money you borrow. It doesn’t include fees or interest.
Interest is typically calculated based on the amount you borrow, so a larger principal often means you'll pay more interest over the life of the loan.
Subsidized vs. unsubsidized student loans
Whether you’re just starting college or already working toward your degree, it’s important to understand your student loan options. When exploring federal student loans (opens in a new tab), one of the most important distinctions is whether the loan is subsidized or unsubsidized.
Subsidized loans are available to students with demonstrated financial need. Their biggest advantage is that the U.S. Department of Education pays the interest during certain periods, such as while you're enrolled in school at least half-time.
Unsubsidized loans are available regardless of financial need, but interest begins accruing as soon as the loan is disbursed. As a result, you could repay more over the life of the loan if unpaid interest continues to accumulate.
Both loan types have eligibility requirements, but understanding how interest works can help you better estimate the total cost of borrowing and make a more informed decision before accepting a loan.
Traditional IRA vs. Roth IRA
Retirement might seem far away, but the earlier you start saving, the more time your money has to grow. Understanding the difference between retirement accounts is crucial in saving for your future.
A traditional IRA allows you to contribute money now and pay taxes when you withdraw it later in life.
A Roth IRA works the opposite way. You pay taxes now on the money you're putting in, and you can generally withdraw it tax-free in retirement.
Both options are great ways to invest in your future. The biggest difference is when you pay taxes. For many college students and young adults who are in a lower tax bracket, a Roth IRA may be a good option because you're paying taxes on your contributions while your income is still relatively low.
You don't need to be a financial expert to make smart decisions. Understanding common terms like APR, DTI and net worth takes some of the mystery out of managing your money. Whether you're starting your first job, paying for college or planning for the future, a little financial knowledge goes a long way.
