What is a Three Statement Model?

Introduction To Three Statement Model?

A three statement model is one of the most fundamental tools in financial modeling. It integrates a company’s income statement, balance sheet, and cash flow statement into a single, connected model that shows how financial performance flows across all three reports. This integration ensures consistency, accuracy, and transparency when analyzing a business.

In simple terms, the three statement model links profitability, assets and liabilities, and cash movements together. For example, net income from the income statement feeds into retained earnings on the balance sheet and also drives the operating cash flow section of the cash flow statement. This dynamic connection makes the model a reliable framework for understanding a company’s financial health.

Why It Matters in Finance

Corporate Finance: Helps management forecast results, allocate capital, and evaluate strategic decisions.
Investment Banking: Forms the foundation for valuation models such as Discounted Cash Flow (DCF), Leveraged Buyout (LBO), and Merger Models.
Equity Research & Investing: Provides a transparent view of how assumptions flow across financial statements, making valuations more robust.

At its core, the three statement model represents financial modeling basics, giving analysts the foundation they need to build advanced models, test scenarios, and support investment decisions with confidence. Explore: Accounting Training Courses

The Three Financial Statements Explained

At the heart of every three statement model are the three core financial statements: the income statement, the balance sheet, and the cash flow statement. Together, these three statement model components provide a complete picture of a company’s profitability, financial position, and liquidity.

Income Statement

Shows revenues, expenses, and net profits over a period.
Captures operating performance by detailing how sales translate into earnings.
Key line items: revenue, cost of goods sold (COGS), operating expenses, interest, taxes, and net income.

Balance Sheet

Reports a company’s assets, liabilities, and shareholders’ equity at a given point in time.
Follows the fundamental equation: Assets = Liabilities + Equity.
Provides insight into financial health, leverage, and resource allocation.

Cash Flow Statement

Breaks down actual cash movements into three sections:
- Operating activities – cash generated from core business operations.
- Investing activities – cash spent on or received from investments in assets.
- Financing activities – cash raised from or returned to investors and creditors.
Demonstrates how profits translate (or fail to translate) into liquidity.

Why These Three Form the Foundation

Individually, each statement provides valuable information, but when integrated, they offer a holistic view of financial performance. For example:

Net income from the income statement flows into retained earnings on the balance sheet.
Changes in working capital on the balance sheet affect operating cash flow.
Capital expenditures appear in both the balance sheet (as assets) and the cash flow statement (as outflows).

This interconnection is why the income, balance, and cash flow statements are inseparable in financial modeling and form the basis for advanced valuation techniques.

How the Three Statement Model Works

The strength of the model lies in its ability to connect the three financial statements so that a single change in assumptions flows through all areas of performance. Understanding how the three statement model works ensures accuracy and consistency in financial forecasting.

Linking Net Income to Retained Earnings

Net income from the income statement is the starting point.
That figure flows into the balance sheet under retained earnings, increasing equity.
It also forms the foundation for operating cash flow in the cash flow statement.

Connecting Depreciation and Capital Expenditures

Depreciation reduces net income on the income statement but is added back in the cash flow statement because it is non-cash.
Capital expenditures appear as outflows under investing activities in the cash flow statement.
At the same time, CapEx increases property, plant, and equipment (PP&E) on the balance sheet, while depreciation decreases it over time.

Updating Debt and Equity Through Financing Activities

Borrowings and repayments affect cash flow from financing and update the debt balance on the balance sheet.
Issuing new equity raises cash in financing activities and increases shareholders’ equity.
Dividend payments reduce retained earnings on the balance sheet and show as cash outflows in financing.

Why This Matters

The three statement model explained is essentially about integration. Every assumption—whether sales growth, CapEx, or new debt—affects all three statements simultaneously. This interconnected framework makes the model a powerful tool for forecasting and valuation. Explore: Finance & Budgeting Training Courses

How to Build a Three Statement Model Step by Step

A solid workflow keeps your model accurate, auditable, and easy to iterate. Here’s how to build a three statement model—from clean inputs to a balancing output—using best-practice structure that also works seamlessly in a three statement model in Excel.

Step 1: Input Historical Financial Data

Start with a clean, consistent foundation.

Collect 3–5 years of the income statement, balance sheet, and cash flow statement.
Normalize one-offs (asset sales, impairments, restructuring) so history reflects core operations.
Standardize a chart of accounts (e.g., group lines into Revenue, COGS, OpEx, D&A, Interest, Taxes).
Quality checks: totals tie to filings; cash roll-forward reconciles; no sign errors (outflows negative).
Model hygiene: separate tabs for Inputs / Calc / Output, a single timeline row (months or years), and a transparent Units convention (e.g., $000s).

Step 2: Project Revenue Growth and Key Assumptions

Translate business drivers into forecast levers.

Revenue drivers: price × volume, segment mix, churn/retention, utilization, new launches.
Margins: gross margin %, opex as % of revenue or run-rate with productivity assumptions.
Working capital: model DSO / DPO / DIO (or AR/AP/Inventory as % of revenue/COGS) to derive ΔNWC.
CapEx & D&A: link capital expenditure to growth/maintenance; use a PP&E roll-forward to calculate depreciation.
Taxes & financing: effective tax rate; interest from an average debt balance; share count/dividends policy.
Scenario inputs: base / upside / downside toggles to stress test assumptions.

Step 3: Build Income Statement Forecasts

Lay out the P&L from top line to net income.

Revenue → Gross Profit: Revenue and COGS (or gross margin %) drive gross profit.
Operating expenses: SG&A/R&D (absolute or % of revenue) → EBIT(DA).
Below the line: interest expense/income, other non-operating items, taxes → Net Income.
Linkages: depreciation from the PP&E schedule; interest from the debt schedule; tax from a consistent EBT × rate framework.

Step 4: Link to Balance Sheet and Cash Flow Statement

This is where the model “integrates.”

Balance Sheet Schedules:
- PP&E roll-forward: Opening PP&E + CapEx – Depreciation = Closing PP&E.
- Working capital schedule: AR, AP, Inventory from DSO/DPO/DIO → ΔNWC.
- Debt & equity: Borrowings/repayments, issuances/buybacks, dividends → update balances.
Cash Flow Statement (indirect method):
- CFO: Net Income + non-cash (D&A, SBC) – ΔNWC.
- CFI: CapEx (negative), acquisitions/disposals.
- CFF: Debt issuances/repayments, equity flows, dividends.
- Ending cash: Beginning cash + CFO + CFI + CFF → feeds back to the cash line on the balance sheet.
Retained earnings roll-forward: Prior RE + Net Income – Dividends = Current RE.

Step 5: Check Model Balance (Assets = Liabilities + Equity)

Bake in control checks so issues surface immediately.

Balance check cell: Assets – (Liabilities + Equity) = 0; flag if non-zero.
Cash is the output, not a plug: derive from the cash flow statement, then link to the balance sheet.
Cross-checks:
- Cash waterfall ties (Beg Cash + CFO + CFI + CFF = End Cash).
- PP&E roll-forward matches D&A and CapEx used in P&L/CF.
- Retained earnings ties to NI and dividends.
Iteration & circularity: interest often creates a loop; if needed, use Excel’s iterative calc with stable logic (and document it).

Mini Flow Example (one-year snapshot)

Assumptions: Revenue +8%, gross margin 45%, SG&A 20% of revenue, CapEx = 5% of revenue, DSO 45 / DPO 30 / DIO 50, tax 25%, average debt $50m at 6%.
P&L: Revenue → COGS → Gross Profit → OpEx → EBIT → Interest → EBT → Tax → Net Income.
BS links:
- PP&E: +CapEx – Depreciation → closing PP&E.
- AR/AP/Inventory from days assumptions → ΔNWC.
- Debt unchanged (or update per policy) → interest.
CF: CFO = NI + D&A – ΔNWC; CFI = –CapEx; CFF = policy-driven; Ending Cash feeds balance sheet.
Check: Assets = Liabilities + Equity; retained earnings increase by NI – Dividends.

Excel Tips (that save hours)

Use XLOOKUP/INDEX-MATCH (not VLOOKUP) for resilient mapping; SUMIFS for subtotals.
Keep inputs blue, calcs black, links green (or your house style) for instant readability.
Add data validation for scenario switches; use named ranges for key rates (tax, WACC).
Avoid hard-coding in formulas; centralize assumptions on an Inputs tab with clear labels and units.

This stepwise approach makes how to build a three statement model repeatable and audit-ready—and, because it’s structured for spreadsheet workflows, it drops directly into a robust three statement model in Excel. Explore: Investment Management Training Courses

Why the Three Statement Model is Important

The importance of the three statement model lies in its ability to provide a complete, connected view of a company’s financial performance. By integrating the income statement, balance sheet, and cash flow statement, it ensures consistency across all metrics and makes financial projections more reliable. This interconnected framework is why it serves as the backbone of financial modeling in corporate finance, investment banking, and equity research.

Key Uses of the Three Statement Model

Foundation for Advanced Models: Forms the starting point for complex valuation and transaction models such as Discounted Cash Flow (DCF), Leveraged Buyout (LBO), and Merger Models.
Scenario Testing: Enables analysts to change assumptions (e.g., revenue growth, CapEx, financing mix) and instantly see how those changes affect profitability, liquidity, and solvency.
Financial Health Assessment: Offers a comprehensive view of performance, making it easier to evaluate leverage, cash generation, and returns on equity.
Decision-Making Tool: Helps executives, investors, and lenders assess whether a company is on track to meet its objectives and withstand potential risks.

Why It Matters in Practice

The uses of financial models built on this structure go beyond just forecasting. They support capital allocation, risk management, deal negotiations, and strategic planning. In short, the three statement model is not only a technical requirement but also a strategic tool that underpins critical financial decisions.

Advantages and Limitations of the Three Statement Model

Like any financial framework, the three statement model has both strengths and weaknesses. Understanding the pros and cons of the three statement model helps analysts, executives, and investors apply it effectively while recognizing its boundaries.

Advantages

Comprehensive View: Captures profitability (income statement), financial position (balance sheet), and liquidity (cash flow).
Integrated Structure: Ensures that assumptions flow consistently across all three statements, reducing errors and improving accuracy.
Widely Used: Serves as the global standard in corporate finance, investment banking, and equity research, making it highly transferable across industries and roles.
Foundation for Advanced Models: Acts as the building block for more complex valuation frameworks like DCF, LBO, and merger models.

Limitations

Time-Consuming: Building a fully linked model requires detailed inputs, schedules, and reconciliations.
Assumption-Driven: Forecast accuracy depends heavily on the quality of assumptions; unrealistic inputs can distort outputs.
May Oversimplify Reality: Even integrated models cannot capture every market dynamic, regulatory shift, or macroeconomic risk.
Technical Complexity: Circular references (e.g., interest linked to debt balances) can create errors if not managed carefully.

Bottom Line

The three statement model is one of the most powerful tools in financial modeling, but it is not foolproof. Its real value lies in combining it with sound judgment, conservative assumptions, and cross-checks against other valuation methods.

FAQs on the Three Statement Model

What are the three statements in the model?

The three statement model integrates the income statement, balance sheet, and cash flow statement into one connected framework. This allows analysts to see how profitability, financial position, and cash flows interact.

Why do financial analysts use the three statement model?

Analysts use the model because it provides a complete, integrated view of financial health. It helps test assumptions, forecast future performance, and serves as the foundation for advanced models like DCF, LBO, and merger models.

Can you build a three statement model in Excel?

Yes. Most professionals build the three statement model in Excel because of its flexibility and formula-based linking. Excel makes it easy to connect net income to retained earnings, tie depreciation and CapEx to PP&E, and reconcile ending cash balances across all three statements.

What is the difference between the three statement model and DCF?

The three statement model is primarily a forecasting tool that shows how the three financial statements link together. A DCF model, on the other hand, uses those forecasts (especially free cash flows) and applies a discount rate (WACC) to estimate intrinsic value. In short, the three statement model is the foundation, while DCF is one of the applications.

Conclusion

The three statement model in finance is the backbone of financial analysis, corporate planning, and valuation. By linking the income statement, balance sheet, and cash flow statement into one integrated framework, it provides a clear and consistent picture of a company’s performance. This makes it the essential starting point for anyone learning financial modeling.

For aspiring analysts and professionals, mastering the basics of building a three statement model is a critical step before moving on to advanced valuation techniques such as DCF, LBO, or merger models. Practicing in Excel with historical data and forecast assumptions not only strengthens technical skills but also builds the discipline needed to create accurate, transparent, and decision-ready models.

In short, the three statement model is more than just a technical exercise—it is the foundation of financial modeling that drives better decision-making in corporate finance, investment banking, and investing.
