Definition
A balance sheet is a document that shows how much a company owns and how much it owes as of a set date. It lays out in one view how the company's total property (assets), the debts it must repay (liabilities), and the truly-yours money (equity) fit together.
What happens when you buy a $400,000 house
Imagine you buy a home worth $400,000. You put in $160,000 of your own cash and borrow $240,000 from the bank. The whole house, which you can live in or put to work as you like, is worth $400,000.
In accounting, everything you hold like this is called your assets. The $240,000 you owe the bank is a liability. And the real money that's left after subtracting the debt, your $160,000, is equity.
This gives us the most basic and famous formula. Assets equal liabilities plus equity. Every dollar a company uses to run its business came from one of two places: money borrowed from others, or money its owners put in.
That's why you need to look closely, even at a big company with a huge building. If it took on too much debt to get that building, the solid equity it actually holds may be much smaller than it looks.
It's a snapshot, not a video
When people read financial statements, many mix up the income statement and the balance sheet. The income statement is like a "YouTube video" showing how much money the company earned and spent over a year. The balance sheet is a snapshot of one moment, taken by freezing time at midnight on December 31.
That's why the top of a balance sheet says something like "As of December 31, 2024." It names just one day. Even if a company sold a lot and earned well all year, if it spent all that cash elsewhere by year-end, the snapshot will show very little cash left.
On the other hand, a quiet company that received a big investment just before year-end will look like its bank account is full in that day's snapshot. It's a still frame showing where the company's journey had landed on that date.
Investors use this one picture to check a company's financial strength. They can see how much of its assets is cash ready to use right now, and whether it's scrambling to pay off debts that are about to come due.
To be more precise: a perfect balance between left and right
To be more precise, a balance sheet is split into a left side and a right side that face each other. It gets the name "balance" because the two sides always come out to exactly the same total. (In Korea it was long known by an older name, daechadaejopyo, meaning a debit-and-credit balance table.) The left side lists what the company owns. The right side lists where the money came from to get it.
Items also follow a common order. They're usually listed from easiest to turn into cash to hardest (this is the usual practice under Korea's general accounting standards, while international standards allow other layouts). Bank deposits you could withdraw tomorrow go at the top. Factory land, buildings, and machines, which take a long time to sell, go near the bottom.
The liabilities on the right work the same way. Urgent debts due next month or this year go at the top. Long-term loans you can repay slowly over several years go lower down. That makes it easy to compare the top assets against the top liabilities.
Thanks to this, readers don't have to crunch lots of numbers. With one glance, they can compare what they can turn into cash within a year against what they must pay within a year, and tell whether the company can pay its debts on time.
Common misconceptions
A company with lots of assets has no debt and must be rich.
Assets include property bought with borrowed money. A company with a building worth 10 billion won (about $7 million) but 9.5 billion won in debt has only 500 million won (about $350,000) of its own money, its equity.

In one sentence
A balance sheet is a snapshot, taken on a specific date, of what a company owns (assets), what it owes (liabilities), and what is truly its own money (equity).
