10 Personal Finance Questions, Finally Answered

Nobody, from your accountant to the financial influencers you see on social media, is born knowing what an index fund is, how to calculate cash flow, or why you need a credit score to get a loan. Even so, personal finance literacy is crucial to navigating the modern world.

In the 2026 TIAA-GFLEC Personal Finance Index survey, U.S. adults answered less than half (47%) of basic money questions correctly, which is the lowest score in the survey's decade of running.

So if you’re still wondering what a 401(k) is, pondering how much you should have an emergency fund (or if you should have one at all), or still trying to wrap your head around how credit scores work: you’re not alone.

No matter where your financial knowledge is, we have the answers. Let’s dive in.

#The Top 10 Essential Financial Questions

1. #What is a 401(k), actually?

A 401(k) is a tax-advantaged, long-term retirement savings plan that’s offered by employers as a perk for their employees.

Investment accounts are a good way to save for the long run, because the money grows faster than it simply sitting in a savings account. This means you beat long-term inflation and you can save more over time with compounding interest.

A 401(k) in particular comes with a few extra bonuses beyond your run-of-the-mill investment account. Your contributions are made pre-tax, which allows you to save more and lower your taxable income for the years you contribute.

When you’re employed at the company providing the 401(k), your employer will cover the fees associated with administering and managing the 401(k). Many employers also will match your contributions up to a certain percentage of your salary, which is essentially free money. If you leave the company, you can choose to maintain the 401(k) account and pay the fees yourself, or roll the funds over to an individual retirement account (IRA).

Because it’s tax-advantaged, there is an upper limit to how much you can contribute to your 401(k) per year. For 2026, the 401(k) employee contribution limit is $24,500, with an additional $8,000 catch-up contribution available if you’re ages 50 to 59, and $11,250 if you’re ages 60 to 63.

Finally, because a 401(k) is a retirement account, you will have to pay both taxes and monetary penalties if you withdraw from it before retirement, with a few exceptions established by the IRS.

#2. Is it bad to only pay the minimum on my credit card?

Yes. Paying only the minimum on your credit card not only builds up interest on your balance, but also hurts your credit score and your ability to qualify for other loans and credit products.

While paying the minimum will stave off late fees and penalties, keeping a balance on your card is expensive. For example, if you have a $1,000 balance on a card with 22% APR and a minimum payment of $30, it will take you 9 years and four months to pay off your balance alone, with $1,066 in accrued interest on top of your principal.

Keeping a balance also keeps your card utilization high, which negatively impacts your credit score and impacts your overall debt to income ratio, which can disqualify you for loans or other credit cards. Contrary to popular belief, you don’t need to maintain a balance to increase your credit score or maintain a credit profile; all you need to do is have an active card, which you can pay off in full and still keep open.

Instead, it’s a better idea to pay off your card balance as much as you can, after establishing a $1,000 emergency fund and ensuring you have basic medical and car insurance. If you have multiple balances, using the snowball or avalanche methods can help you prioritize how to organize your payments and pay off your debts more quickly. If you have a good credit score, you can use a balance transfer card with a 0% introductory rate to give yourself some breathing room while you pay off the balance.

#3. How many bank accounts should I have?

While it depends on your financial situation, most adults have three bank accounts:

• A checking account that allows you to quickly make payments with checks and a debit card
• A high-yield savings account for emergency fund savings
• A savings account for other savings goals, such as a wedding fund, a vacation fund, or a house savings fund

If you share finances with a long-term partner, you may choose to jointly own these accounts with your partner, keep your accounts separate, or choose to keep separate accounts with one or two shared accounts between you.

Additionally, if you own a business, it may make sense to have additional business and checking accounts in order to keep your business funds separate from your personal funds.

#4. How much should I have in savings?

In general, you’ll want to have an emergency fund that can cover for unexpected expenses or help you pay the bills if your income suddenly drops without having to rely on credit card debt or taking out a loan.

According to the Federal Reserve’s Survey of Household Economics and Decisionmaking, in 2025, only 55% of households have three months of essential expenses saved up, with 37% of all American adults being unable to cover a $400 emergency expense with cash.

To start off, if you have no emergency fund and have outstanding, high-interest debt, aim for either one month of living expenses or $1,000 in savings, whichever is higher.

After paying or refinancing off all debts over 25%, start saving for a multi-month emergency fund. If you’re a non-homeowner with no pets or dependents, a stable income, reliable transportation to work, have health insurance with a deductible for less than three months of living expenses, and have a non-financial safety net, aim for three months of savings.

If your income is less reliable, or if your primary source of income would be difficult to replace if you lose your job, then aim to save nine to twelve months of living expenses.

Otherwise, save six months of your living expenses for emergencies.

#5. What's a credit score and why does everyone obsess over it?

A credit score tells lenders and credit card providers what your borrowing and payment history is, and how much of a risk it would be to lend to you based on your past behavior. The higher your score, the less risky it is to lend to you. This means you’ll have an easier time being approved for loans and credit cards and get better interest rates and terms.

Credit scores range from about 300 to 850, depending on the scoring model. The score ranges for FICO, which is the most common score used by lenders, are:

• Poor: 300 to 579
• Fair: 580 to 669
• Good: 670 to 739
• Very Good: 740 to 799
• Exceptional: 800 to 850

In order to have a credit score on file, you must have either an outstanding loan that you are paying down, or an active credit card. If you don’t have either of those, then you are considered “credit invisible” by lenders and will have a harder time getting loan or card applications approved.

There are five key factors that go into calculating your credit score, which are determined by your credit report. These factors are:

• Payment history, including your on-time and missed payments. Having a long history of on-time payments will increase your score, while missing payments, having accounts default or go to collections, or filing for bankruptcy will drop your score. This is the most impactful part of your score.
• Utilization of your revolving credit lines, which is essentially the ratio of your credit card balances to your credit limit. High utilization (such as maxing out your cards) will drop your score.
• Age of accounts that you currently have active. Old, long-standing accounts, like a credit card you’ve had for multiple years, will increase your score.
• New credit/hard inquiries from applying for new credit and loan products. While new inquiries only drop your score by a few points for a relatively short period of time, multiple inquiries in a short period can quickly drop your score.
• Credit mix of the loans and credit cards you have. Lenders prefer you have a mix of installment loans (like a mortgage or student loan) and revolving credit (credit cards) instead of only one type.

#6. What's the difference between a Roth IRA and a 401(k)?

While Roth IRAs and 401(k)s are both tax-advantaged investment funds that help you save for retirement, there are a few key differences to be aware of. Here’s a quick breakdown of the differences between the two.

For a more detailed breakdown, check out our pages on the differences between investment vehicles and retirement accounts.

#7. What is compound interest and why do people call it magic?

Compound interest means that an interest-bearing balance, like money in a high-yield savings account, grows exponentially over time. This is because, as the balance accumulates interest, each time the interest is calculated, it calculates the interest based on both the original balance and the previous interest that’s been added to the account.

For example, let’s say you have an interest-bearing savings account with a 7% fixed interest rate, compounded (calculated) monthly. With a starting balance of $200, you contribute $200 each month afterward.

After 30 years, you’ll have made $72,000 in contributions. The balance, however, will be far greater than that. With compound interest, you’ll have earned $173,000 in interest, for a total balance of about $245,000.

Compound interest applies to any growth-oriented or interest-bearing savings or investment account, which is why it’s the ideal way to save for the long term.

#8. Do I actually need a budget if I'm not broke?

You do. Budgets aren’t always about putting a cap on your spending or limiting your purchases. Instead, think of a budget as a roadmap for your money, where you want it to go, and how you plan to use it to further your financial goals.

Budgeting also doesn’t mean counting every penny or spending hours on a spreadsheet. You can build a budget that fits your financial lifestyle, whether you want to aggressively save and cap your spending, or if you want to have a more hands-off approach.

The key thing with a budget is that you’re creating awareness about your spending, and a plan for what you do with your money. Knowing where your cash is going, how much you have left over at the end of each month, and if you’ll have enough to cover for a large or unexpected expense can go a long way to build your financial resilience and give you better peace of mind about your money.

#9. Should I pay off debt or save first?

A bit of both. Saving before you’ve paid off your debt will set you back as your interest accumulates. On the other hand, neglecting your emergency fund to pay off debt puts you at risk if you face an unexpected expense.

If you have debt and no savings, here’s how you should save and pay in order of priorities:

1. Ensure you can make the minimum payments on all your debts before saving anything, as well as the payments on your housing and basic health, auto, and homeowners/renters insurance.
2. Save $1,000 or one month’s worth of living expenses, whichever comes first.
3. If your employer offers a retirement savings account, contribute up to 6% of your gross income and take advantage of any contribution matching.
4. If you have debt with over 25% interest, see if you can refinance for a lower rate, use a balance transfer credit card with a low introductory rate. Prioritize paying down your debts with over 10% interest using a debt repayment method like the snowball or avalanche method.
5. Afterward, start saving up a more substantial emergency fund of three to twelve months’ living expenses (see Question 4, “How much should I have in savings” for more details on how much to save).

#10. Is it better to rent or buy right now?

It depends on your financial circumstances, the market, your general timeline, and your overall priorities.

A good place to start is to use the 5% rule. When looking at a property you wish to buy, take 5% of the home’s purchase price and divide it by 12. If that number is lower than the current monthly rent for a comparable home, then it’s a good idea to buy. For example, if you are looking to purchase a $150,000 condo, and the current rent on a similar unit is $2,000 per month, then it’s a better idea to buy, since 5% of the home’s value divided by 12 is $625.

This is because your home 5% is the approximate value of unrecoverable costs (interest, property taxes, and insurance) that don’t contribute to your home’s equity. If these costs are under how much you’re paying in rent, then you’re earning more in equity contributions than you are saving by renting.

Another thing to consider is your credit profile. If your score is on the lower side, you may want to hold off on buying. While you can still qualify for a mortgage with a suboptimal score, you’ll likely be charged a higher interest rate, which costs you more in the long run.

Mortgage rates will also play a large part in how much you pay. Higher mortgage rates mean that you have less purchasing power, since more of your monthly payment will be going to interest.

The housing market itself is also a key factor. In a red-hot housing market, it’s more difficult to buy. Prices can increase from bidding wars, and homeowners will generally prefer all-cash offers over a mortgage, or will only consider offers that waive inspection or financing contingencies.

Last of all, consider your timeline. Realtors generally recommend owning a particular home for at least five years, since this gives your equity time to catch up and recoup the costs of moving and purchasing a home.
