After completing this lesson, you’ll be able to read the three primary financial statements — the balance sheet, the income statement, and the cash flow statement — identify what each one tells you about a business, and explain how the three statements connect to form a single interlocking picture.
From trial balance to financial statements
In the previous lesson’s exercises, you built a trial balance for a small consulting business:
| Account | Debit | Credit |
|---|---|---|
| Cash | $14,800 | |
| Equipment | $3,000 | |
| Inventory | $2,000 | |
| Accounts Payable | $2,000 | |
| Loans Payable | $5,000 | |
| Owner’s Equity | $10,000 | |
| Service Revenue | $4,000 | |
| Rent Expense | $1,200 | |
| Total | $21,000 | $21,000 |
A trial balance proves that debits equal credits, but it doesn’t tell you much at a glance. Financial statements reorganize the same data into three views, each answering a different question:
- Balance sheet — What does the business own and owe right now?
- Income statement — Did the business make or lose money over a period?
- Cash flow statement — Where did cash come from and where did it go?
Every account in the trial balance lands on exactly one of these statements. Asset, liability, and equity accounts go to the balance sheet. Revenue and expense accounts go to the income statement. And the cash flow statement traces the movement of one specific asset — cash.
The balance sheet
The balance sheet is a snapshot of the business at a single point in time. It’s the accounting equation in report form:
Using the trial balance above, here’s the balance sheet for the consulting business as of March 31:
Balance Sheet — As of March 31
| Assets | |
|---|---|
| Cash | $14,800 |
| Inventory | $2,000 |
| Equipment | $3,000 |
| Total Assets | $19,800 |
| Liabilities | |
|---|---|
| Accounts Payable | $2,000 |
| Loans Payable | $5,000 |
| Total Liabilities | $7,000 |
| Equity | |
|---|---|
| Owner’s Equity | $10,000 |
| Net Income (from income statement) | $2,800 |
| Total Equity | $12,800 |
| Total Liabilities + Equity | $19,800 |
Notice two things. First, total assets (19,800) — the equation balances, as it must. Second, net income of 2,800 comes from in the next section.
The income statement
The income statement covers a period of time — a month, a quarter, or a year. It answers: how much did the business earn, and how much did it spend to earn it?
The structure is straightforward: revenues minus expenses equals net income.
Income Statement — For the Month Ended March 31
| Service Revenue | $4,000 |
| Less: Rent Expense | ($1,200) |
| Net Income | $2,800 |
That $2,800 is the number that flows into equity on the balance sheet. If expenses had exceeded revenue, the business would’ve reported a net loss, and equity would’ve decreased.
A real business will have many more line items — cost of goods sold, salaries, utilities, depreciation — but the logic stays the same. Revenue minus expenses gives you the bottom line.
The cash flow statement
The cash flow statement tracks every movement of cash over a period. It groups cash flows into three categories:
- Operating activities — cash generated or spent running the core business (collecting from customers, paying suppliers, paying rent).
- Investing activities — cash spent on or received from long-term assets (buying equipment, selling property).
- Financing activities — cash from or to owners and lenders (owner investments, loan proceeds, loan repayments, dividends).
Here’s the cash flow statement for the consulting business:
Cash Flow Statement — For the Month Ended March 31
| Operating Activities | |
|---|---|
| Cash received from clients | $4,000 |
| Cash paid for rent | ($1,200) |
| Net cash from operating activities | $2,800 |
| Investing Activities | |
|---|---|
| Purchase of equipment | ($3,000) |
| Net cash from investing activities | ($3,000) |
| Financing Activities | |
|---|---|
| Owner’s investment | $10,000 |
| Loan proceeds | $5,000 |
| Net cash from financing activities | $15,000 |
| Net increase in cash | $14,800 |
| Cash at beginning of period | $0 |
| Cash at end of period | $14,800 |
The ending cash of $14,800 matches the Cash line on the balance sheet. It always must.
Why profit doesn’t equal cash
This simple example happens to show equal operating cash flow and net income ($2,800), because the business collected all its revenue in cash and paid all its expenses in cash during the same period. Real businesses aren’t that tidy.
Consider what happens if the consulting business completed 4,000 in revenue and 0 received from clients, making operating cash flow negative $1,200 (just the rent payment going out).
The business is profitable on paper but bleeding cash. This is how profitable businesses run out of money: they’ve earned revenue they haven’t collected, they’ve purchased equipment with cash, or they owe payments on loans — all timing differences between when income is recognized and when cash actually moves.
How the three connect
The three statements form an interlocking system:
- Net income from the income statement flows into equity on the balance sheet. Profit increases what the owners have; losses decrease it.
- Ending cash from the cash flow statement matches the cash line on the balance sheet. The cash flow statement explains how cash moved from its beginning balance to its ending balance.
- The balance sheet must balance after incorporating both. If you change a number on one statement, at least one number on another statement must also change to keep the system consistent.
Think of it this way: the balance sheet is a photograph — it shows where things stand at one moment. The income statement and cash flow statement are videos — they show what happened between two photographs. Together, they give you both position and motion.
Self-check exercises
Exercise 1: Using the trial balance below, prepare a balance sheet. Does it balance?
| Account | Debit | Credit |
|---|---|---|
| Cash | $8,500 | |
| Accounts Receivable | $3,000 | |
| Equipment | $6,000 | |
| Accounts Payable | $1,500 | |
| Loans Payable | $4,000 | |
| Owner’s Equity | $7,000 | |
| Service Revenue | $9,000 | |
| Salaries Expense | $3,500 | |
| Rent Expense | $500 | |
| Total | $21,500 | $21,500 |
Answer
First, calculate net income: 3,500 salaries - 5,000 net income.
Balance Sheet
| Assets | |
|---|---|
| Cash | $8,500 |
| Accounts Receivable | $3,000 |
| Equipment | $6,000 |
| Total Assets | $17,500 |
| Liabilities | |
|---|---|
| Accounts Payable | $1,500 |
| Loans Payable | $4,000 |
| Total Liabilities | $5,500 |
| Equity | |
|---|---|
| Owner’s Equity | $7,000 |
| Net Income | $5,000 |
| Total Equity | $12,000 |
Total Liabilities + Equity = 12,000 = $17,500. It balances.
Exercise 2: For each item, identify which financial statement it appears on — balance sheet (BS), income statement (IS), or cash flow statement (CF):
- Accounts Receivable
- Salaries Expense
- Cash paid to purchase a truck
- Loans Payable
- Service Revenue
- Owner’s investment of cash into the business
Answer
- Accounts Receivable — BS (it’s an asset)
- Salaries Expense — IS (it’s an expense)
- Cash paid to purchase a truck — CF (investing activities — it’s a cash outflow for a long-term asset)
- Loans Payable — BS (it’s a liability)
- Service Revenue — IS (it’s revenue)
- Owner’s investment of cash — CF (financing activities — cash came from the owner)
Exercise 3: A business reports net income of 5,000. Give at least two reasons that could explain why a profitable business saw its cash decline.
Answer
Several timing and investment factors can cause cash to drop even when a business is profitable:
- Uncollected receivables — The business recognized revenue but hasn’t received cash yet. If it billed $15,000 of work that clients won’t pay until next quarter, that revenue boosted net income but not cash.
- Capital purchases — The business bought long-term assets (equipment, vehicles, property) with cash. These purchases don’t appear on the income statement as expenses (they’re assets), but they drain cash immediately.
- Loan repayments — The business repaid principal on a loan. Loan repayments reduce cash but aren’t an expense on the income statement (only interest is an expense; principal repayment is a financing activity).
- Prepaid expenses — The business paid cash up front for something it’ll use over several periods (like an annual insurance premium), reducing cash now while the expense hits the income statement gradually.
Any two of these (or similar timing explanations) would be correct.
Exercise 4: If net income on the income statement increases by $500, what happens on the balance sheet? Assume the extra income came from a cash sale.
Answer
Two things change on the balance sheet:
- Cash (an asset) increases by $500 — because the sale was collected in cash.
- **Equity increases by 500 of profit belongs to the owners.
Total assets go up by 500, and the balance sheet stays balanced. On the cash flow statement, operating cash flow also increases by $500, and ending cash matches the new cash balance on the balance sheet.
What comes next
You can now read and connect the three primary financial statements. The next lesson covers the accounting cycle and adjusting entries — the process a business follows at the end of each period to make sure revenue and expenses land in the right period before the statements are prepared. You’ll learn why adjustments like accrued expenses and deferred revenue exist, and how to record them.
