FUNDAMENTAL FINANCE
The Necessity of a Checking Account
What it is. How it works. Why you need it.

In the world of personal finance, there are few subjects that are more basic than how to use a checking account.
They are the staple of our society, allowing us to get paid from our jobs, pay our bills, purchase stuff online, and transfer money to both family and strangers alike.
They are nearly ubiquitous in our lives, but do you know how they really work, and why banks even offer them in the first place?
Do you know both the perks and limitations of your checking account?
Why do you even have one in the first place?
Let’s explore all those questions and more in this installment of Fundamental Finance.
The Basics of a Checking Account
From Investopedia,
A checking account is a deposit account held at a financial institution that allows withdrawals and deposits. Also called demand accounts or transactional accounts, checking accounts are very liquid and can be accessed using checks, automated teller machines, and electronic debits, among other methods.
Checking accounts came about because people wanted a “safe place” to store their excess cash when their mattress no longer fit the bill. Now, they are an essential part of anyone’s basic personal finance system.
As mentioned above, the best thing about checking accounts is that they are immediately liquid. You can roll up to an ATM 24 hours a day and withdraw a sizeable amount of cash.
- No questions asked.
- No waiting period.
- No penalties incurred.
(ATM fees are simply flat fees, not penalties such as those incurred by withdrawing early from an IRA.)
Just quick easy access to your funds.
In return, you get accrue interest at the sky high amount of 0.01%! (At least, that’s my interest rate at Chase. And yes, I’m looking around)
While you don’t make any money with a checking account, it’s a damn sight better than lugging around your entire paycheck in cash, then paying your bills in cash.
The Benefits of a Checking Account
The biggest attraction to having a checking account is that it can be accessed, linked to, and immediately used for just about anything.
- Use direct deposit to skip going to the bank every payday.
- Link it to Venmo to transfer money for Facebook Marketplace purchases.
- Set up automatic transfers to a savings account to pay yourself first when you get your paycheck.
- Pay a bill online and avoid the check, stamp, and snail mail hassle.
The flexibility and immediate availability are the best reasons to open a checking account.
FYI: Not All of Your Money Is At The Bank
You might have wondered what banks do with all the cash they have lying around.
The answer? They lend it out.
Say you deposit $1,000 in your checking account. Well, just keeping that full amount in a “free” checking account that isn’t incurring fees or interest won’t make them any money.
In fact, checking accounts are used as loss leaders across the entire banking industry.
While you deposit won’t make any money, a loan will.
The bank takes $900 of your money and lends it out, with interest, leaving only $100 in the bank available for withdrawal.
This lending of deposits is the very definition of fractional banking that is the core of the American financial system.
It might seem risky, as a lot of people might want all their money all at once. This is what’s known as a “run on the bank”, epitomized by the movie It’s a Wonderful Life.
However, when you have thousands or millions of customers across an entire country who are probably not going to want all their money all at once, the risk decreases substantially.
How Do I Get a Checking Account?
Most any bank or credit union will gladly open an account for you. They’ll even make it “free” if you agree to direct deposit, a minimum balance, or some other arbitrary requirement.
You’ll get a debit card for free, but physical checks cost extra.
Just remember that a debit card only allows you to spend what is in your account, and no more. It’s not a credit card.
What Traps Should I Avoid?
Since banks lose money on free checking accounts, they set up all sorts of minefields for you to trip on and get hammered with a fee.
The most notorious is the overdraft fee.
If you spend more money than is in your checking account, you have drafted (approved spending) beyond your actual balance.
The bank will cover this extra amount, but not without charging you an overdraft fee, most commonly set at $35 per overdraft.
If you are running at the financial red line every month, I would suggest deactivating this option and avoid the extra charge.
When your overdraft protection is deactivated, your debit card will be declined. Sure, it might be a little embarrassing, but it’s worth the temporary weirdness to save that $35.
The Takeaway
Opening and using a checking account for your daily finances is the most basic step in personal finance.
Most of us have a steady paycheck, repeat expenses, and multiple debts. Having a checking account as the heart of your money system is the first step to establishing great financial habits.
Spend wisely, watch out for the fees, and pay yourself first.
