Understanding Your Balance Sheet: Assets, Liabilities, and Equity

The three sections

A balance sheet has three sections: assets, liabilities, and equity. Assets are everything the company owns or is owed, cash, receivables, inventory, equipment. Liabilities are everything the company owes, accounts payable, loans, deferred revenue. Equity is the residual, what's left after subtracting liabilities from assets. The fundamental accounting equation is: Assets = Liabilities + Equity. This always holds.

The balance sheet has three sections: assets (what the company owns), liabilities (what it owes), and equity (the owners' stake). The fundamental equation: assets equal liabilities plus equity. This always balances because every transaction affects both sides. When you borrow $100K, cash goes up $100K (asset) and debt goes up $100K (liability). Balance preserved.

Unlike the P&L, the balance sheet is a snapshot at a single point in time. It shows what the company looked like at the end of a specific day. Comparing balance sheets across dates shows how the company is changing, is cash growing, is debt increasing, is equity being diluted. The trend across periods is often more informative than any single snapshot.

Current vs long-term

Both assets and liabilities are divided into current (due or convertible within 12 months) and long-term (beyond 12 months). Current assets include cash and receivables. Long-term assets include equipment and intellectual property. Current liabilities include accounts payable and short-term debt. Long-term liabilities include multi-year loans and deferred revenue beyond 12 months. This distinction matters for liquidity analysis.

Current vs long-term is the standard division within assets and liabilities. Current means expected to convert to cash or be paid within 12 months. Long-term means longer. Current assets include cash, AR, inventory, prepaid expenses. Long-term assets include fixed assets, intangibles, long-term investments. Current liabilities include AP, accrued expenses, short-term debt. Long-term liabilities include long-term debt, deferred taxes.

The current ratio (current assets divided by current liabilities) is a quick liquidity check. Above 1.5 is comfortable. Between 1.0 and 1.5 is tight but manageable. Below 1.0 means you might not have enough liquid assets to pay near-term obligations. Tracking this ratio monthly catches liquidity issues before they become cash crises.

What to look for

When reviewing a balance sheet, focus on: the cash position and trend, the AR balance relative to revenue (a growing AR relative to revenue can signal collection problems), the debt structure (what's owed and when), and the equity position (is the business solvent, with positive equity, or is it technically insolvent with liabilities exceeding assets). Each of these tells you something different about the health and sustainability of the business.

What to look for: cash and runway (how long can you operate at current burn), AR aging and quality (is any concentrated or overdue), AP aging (are you paying timely or stretching), inventory if applicable (is it moving or building up), and equity (is retained earnings building or shrinking). Each tells you something about operational health.

The balance sheet also reveals things the P&L hides. A company can show profit on the P&L while the balance sheet shows cash declining and AR growing, meaning profits are stuck in uncollected invoices. Without the balance sheet view, the P&L profit number can be misleading.

How the balance sheet connects to the P&L

The balance sheet and P&L are not independent documents, they're connected through the equity section. Net income from the P&L flows into retained earnings on the balance sheet each period. This means a consistently profitable business builds equity over time. A consistently losing business erodes it. If these two documents don't reconcile, something is wrong with the books.

The balance sheet and P&L connect through retained earnings and the equity section. Net income from the P&L flows into retained earnings on the balance sheet. A profitable year grows equity; a loss year shrinks it. This is why the two statements must be read together, neither tells the complete story alone.

Also, every P&L transaction has a balance sheet impact. Revenue increases AR or cash (asset). Expenses decrease cash or increase AP (liability). Depreciation decreases assets. These connections are why reconciling the balance sheet to the P&L is a standard part of month-end close. When the connection is broken, something is miscategorized.
