3-Statement Overview
The three financial statements are the complete picture of a company's financial health. Each answers a different question; together they tell the full story.
Why Three Statements?
A single statement can't capture everything. A company can be profitable on paper but hemorrhaging cash, or have massive assets but be drowning in debt. Each statement exists because the others leave gaps.
Like a medical checkup — blood pressure alone doesn't tell you if someone is healthy. You need all three because each measures something different.
The Three Statements at a Glance
| Statement | What It Shows | Time Dimension | Core Question |
|---|---|---|---|
| Income Statement | Revenue, expenses, and profit | Over a period (quarter/year) | "Is this company profitable?" |
| Cash Flow Statement | Sources and uses of cash | Over a period (quarter/year) | "Where is the cash actually going?" |
| Balance Sheet | Assets, liabilities, and equity | At a point in time (snapshot) | "What does this company own and owe right now?" |
The Income Statement (IS)
The Income Statement measures profitability over a period — typically a quarter or year. It starts with Revenue and subtracts costs until you reach Net Income (the bottom line).
Key line items:
- Revenue — total sales
- COGS (Cost of Goods Sold) — direct costs to produce what was sold
- Gross Profit — Revenue minus COGS
- Operating Expenses (SG&A, R&D) — costs of running the business
- Operating Income (EBIT) — profit from core operations
- Net Income — what's left after interest and taxes
The IS tells you how much was earned, but not whether it translated into actual cash. That's why we need the next statement.
The Cash Flow Statement (CFS)
The Cash Flow Statement tracks actual cash movement in and out of the business over a period. Profitability and cash flow are not the same — a company can book revenue it hasn't collected or expenses it hasn't paid. The CFS reconciles this.
Three sections:
- Cash from Operations (CFO) — cash generated by the core business. Starts with Net Income and adjusts for non-cash items (depreciation, changes in working capital)
- Cash from Investing (CFI) — cash spent on or received from long-term assets. CapEx, acquisitions, asset sales
- Cash from Financing (CFF) — cash from or to capital providers. Issuing/repaying debt, issuing/buying back stock, paying dividends
The CFS ends with ending cash balance — the cash the company actually has on hand.
"What if depreciation goes up by $10?" D&A reduces net income on the IS but gets added back as a non-cash charge on the CFS. Net cash effect = the tax shield. Trace it through all three statements.
The Balance Sheet (BS)
The Balance Sheet is a snapshot of what a company owns, owes, and what's left for shareholders at a specific point in time. A photograph, not a movie.
It follows the accounting equation:
- Assets — what the company owns (cash, inventory, property, equipment, intangibles)
- Liabilities — what the company owes (debt, accounts payable, deferred revenue)
- Shareholders' Equity — the residual belonging to owners (common stock, retained earnings)
The BS must always balance. Every transaction affects at least two line items to keep the equation in equilibrium.
How They Connect: The Golden Thread
Interviewers care about this most. The three statements are linked by a few critical connections (we'll explore these in depth in the linkage lesson later):
- Net Income flows from the IS to the CFS. The CFS starts with Net Income and adjusts for non-cash charges and working capital changes to arrive at actual cash generated.
- Ending Cash on the CFS flows to the BS. The ending cash balance becomes Cash & Cash Equivalents on the Balance Sheet.
- Net Income flows to Retained Earnings on the BS. Net Income (minus dividends) accumulates in Retained Earnings — the direct IS-to-BS link.
"Walk me through the three financial statements." IS shows profitability (Revenue → Net Income). Net Income feeds the CFS, which reconciles to actual cash. That cash lands on the BS, and Net Income flows to Retained Earnings. A = L + E. Done.
A Simple Example
Say a company earns $100 in revenue and has $60 in expenses, with $10 in depreciation included in those expenses.
- Income Statement: Revenue ($100) - Expenses ($60) = Net Income ($40)
- Cash Flow Statement: Net Income ($40) + Depreciation add-back ($10) = $50 cash from operations (simplified)
- Balance Sheet: Cash increases by $50, Retained Earnings increases by $40, and PP&E decreases by $10 (depreciation). Assets ($50 - $10 = +$40 net) = Equity (+$40). It balances.
This is the kind of tracing interviewers expect you to do on the spot.
Key Takeaways
- The IS measures profitability over a period (Revenue → Net Income).
- The CFS tracks actual cash movement, starting from Net Income and adjusting for non-cash items.
- The BS is a point-in-time snapshot following .
- Three links: Net Income → CFS, Net Income → Retained Earnings, ending cash → BS.
- "Walk me through the three financial statements" is the most tested accounting question — know it cold.
