Financial literacy entails having a solid understanding of money management so you can make good decisions when creating a budget, saving and investing money, managing debt and paying taxes.

The consequences of not being financially literate can be costly. In fact, Americans estimated they lost an average of $1,819 in 2022 due to lack of knowledge about personal finances, according to a study by the National Financial Educators Council.

In addition to understanding money management concepts, it’s important to have the skills needed to handle budgeting, managing bills, investing money and saving for retirement and other financial goals.

Here we’ll go over ways lack of financial literacy could be costing you money, as well as ways you can save more money by becoming more knowledgeable about personal finances.

How financial illiteracy can hurt consumers

Lack of knowledge when it comes to your bank accounts could mean you’re being charged fees that are avoidable, and you could also be losing out on opportunities to earn higher annual percentage yields (APYs).

Similarly, not paying attention to your credit card use or misunderstanding your credit card’s terms could cause you to wind up in debt that includes a hefty amount of interest. Whether it’s lack of knowledge about banking, credit cards or ways you might become a victim of financial fraud, financial illiteracy could leave you with unnecessary fees, a low credit score and difficulty borrowing money.

Avoiding the costs of financial illiteracy

Here we’ll look at various ways a lack of personal finance knowledge could be costing you thousands each year, along with ways you could avoid unnecessary fees and put more money back in your bank account.

Bank fees

While bank fees are often easy to avoid, they’re commonly overlooked and can add up quickly. For instance, more than a quarter of Americans with a checking account are paying monthly fees, according to a recent Bankrate survey, which also found that these fees cost account holders an average of $24 a month — or $288 per year.

Monthly maintenance fees

Also known as service fees, monthly maintenance fees are sometimes charged on noninterest checking accounts and can often be waived if you maintain a set minimum balance.

What monthly maintenance fees may be costing you: Among noninterest checking accounts that charge such a service fee, the monthly average is $5.44 (or $65.28 per year), Bankrate’s latest checking account and ATM fee study found.

Ways to avoid monthly maintenance fees: If your bank charges monthly maintenance fees, you may be able to avoid them by maintaining a set minimum balance requirement. Otherwise, it’s not difficult to find a new bank account that doesn’t charge service fees.

ATM fees

The two types of fees you may face for using an out-of-network ATM are a surcharge from the bank that owns the ATM and a charge from your own bank for not using one of its ATMs.

What ATM fees may be costing you: Of these two types of ATM fees, the total combined average fee is $4.66, according to Bankrate’s checking account study.

Ways to avoid ATM fees: Make sure you only use ATMs that are in your bank’s network. If you find yourself needing ATM access frequently and there aren’t many in-network ATMs near you, consider switching to a bank that offers more ATMs. You can also obtain cash and avoid ATM fees by getting cash back at the register when making a purchase.

Overdraft fees

While some banks have reduced or eliminated overdraft fees, others still charge overdraft fees for covering the difference when you spend more money than what’s in your account.

What overdraft fees may be costing you: The average overdraft fee is $29.80, according to Bankrate’s 2022 checking and ATM fee study.

Ways to avoid overdraft fees: Some banks offer overdraft protection, in which case funds are automatically transferred from a linked account if you initiate a transaction that would otherwise overdraw the account. Other ways you can help avoid overdraft fees include setting up low-balance alerts or checking your balance frequently. You can also opt out of overdrafts, meaning any transaction that would overdraft your account will simply be denied by the bank.

Savings account yields

Since savings account APYs vary so widely, it’s important for anyone who wants the best rate to know what their account is earning. However, more than 1 in 10 consumers (14 percent) don’t know what, if any, interest their savings account is earning, Bankrate found. Big banks’ savings accounts often earn interest rates around 0.01 percent, whereas it’s not difficult to find rates elsewhere that earn rates of around 4 percent — 400 times greater than those of the big banks.

Ways to earn a higher yield: If you determine your savings account is earning a lackluster yield, shop around for a bank where you can earn a competitive APY instead. High-yield savings accounts are often found at online banks, which don’t have the overhead expenses of maintaining branches and can pass on the savings.

Credit card interest and fees

When you’re in credit card debt, it’s easy to feel overwhelmed and avoid paying attention to the interest charges on your monthly statement. However, it can be shocking how much that interest adds up over time.

What credit card interest and late fees could be costing you: The average variable credit card annual percentage rate (APR) is currently 20.3 percent — and this rate can be higher for individuals who have low credit scores. For someone carrying a balance of $5,000 and a 20 percent APR, this can translate to around $82 in interest added to your balance in a month — or $984 in a year.

What’s more, if you don’t make your credit card payment on time, you’ll likely be hit with a late fee. Late fees can run you as much as $41 per charge, according to the Consumer Financial Protection Bureau (CFPB).

Ways to avoid credit card interest charges and late fees: A surefire way to avoid being charged credit card interest is by paying off your balance in full each month. If you determine it’ll take you several months to pay off a balance, you may want to consider transferring your balance to a lower-rate card.

You can help avoid late fees on your credit card payments by setting up automatic payments or calendar reminders soon before a payment is due. If you have many bills due at once, consider asking your credit card issuer to change your payment date.

Fraud and identity theft

There are many types of scams in which hackers try to empty your bank account. These include identity theft, phishing, check fraud and peer-to-peer payment scams. Not having knowledge about such crimes can make you more susceptible to becoming a victim of them.

What fraud cost consumers in 2022: Consumers collectively lost $8.8 billion to fraud last year, according to the Federal Trade Commission. This reflects an increase of over 30 percent from 2021.

Ways to avoid being a victim of fraud and identity theft: Read up on common types of bank account fraud to help ensure you don’t fall victim to it. For each of your financial accounts, use multi-factor authentication and have a unique password that would be difficult for others to guess.

Be cautious of emails that appear to be from your financial institution, especially those that ask for your personal information. If you want to verify whether such an email is legitimate, call your bank at a number you know is valid, the Federal Deposit Insurance Corp. (FDIC) advises.

Monitor your bank accounts regularly for any suspicious-looking activity. Likewise, check your credit report regularly for anything unfamiliar, and contact the credit bureau if you suspect fraud. If you suspect bank account fraud, contact your bank and other authorities right away.

Bottom line

Understanding the workings of your bank accounts and credit card accounts can help you avoid fees and penalties, and it can also help you earn higher interest on your savings. Similarly, understanding financial crimes and identity theft can help you keep your bank accounts safe and secure.
