Three-statement model

Link the income statement, balance sheet and cash-flow statement so operating, investment and financing assumptions produce a reconciled forecast.

Quick answer

A three-statement model is a financial model in which the forecast income statement, balance sheet and statement of cash flows are linked through consistent assumptions and supporting schedules. Net income feeds retained earnings and the cash-flow statement; changes in balance-sheet accounts affect cash flow; and the resulting closing cash balance returns to the balance sheet. The model can support planning, valuation, financing and transaction analysis when its definitions, links and checks are controlled.

Meaning and transaction use

CFA Institute describes financial statement modelling as forecasting income statements, balance sheets and statements of cash flows for company and security valuation. [S1]

CFA Institute's modelling curriculum covers revenue, costs, working capital, capital structure, debt and equity schedules, statement construction and troubleshooting. [S2]

The SEC identifies the income statement, balance sheet, statement of cash flows and statement of stockholders' equity as core financial statements and notes that accounting judgments can materially affect reported figures. [S3]

Worked example

Illustrative one-period linkage only. Assume revenue of 100.0 million, operating costs of 70.0 million, depreciation of 5.0 million, interest of 3.0 million, tax of 5.5 million, a 4.0 million increase in working capital, capital expenditure of 8.0 million, 2.0 million of new borrowing, dividends of 3.0 million and opening cash of 10.0 million.

Closing retained earnings40.0 + 16.5 - 3.053.5m
Balance-sheet check150.0 assets - 60.0 liabilities - 90.0 equity0.0m

The illustrative statements produce closing cash of 18.5 million and a zero balance-sheet check. The example demonstrates linkage; it does not establish that the forecast assumptions or accounting treatment are appropriate.

Proposed transaction review process

Set definitions and periods

Define entities, currency, accounting basis, historical periods, forecast horizon and scenario controls.

Load and reconcile history

Tie historical statements and supporting schedules to approved financial records before forecasting.

Build operating and financing schedules

Model revenue, costs, working capital, capital expenditure, tax, debt, equity and other material balances.

Link and test the statements

Flow earnings, cash movements and closing balances through all statements; run balance, cash and roll-forward checks for every period.

Evidence checklist

Historical statements

Audited accounts, management accounts, trial balances and cash-flow reconciliations.

Operating drivers

Volumes, prices, margins, headcount, working-capital days and tax assumptions with owners and dates.

Supporting schedules

Fixed assets, depreciation, debt, interest, leases, equity, retained earnings and cash.

Model controls

Input conventions, version history, change log, scenario definitions, checks and review evidence.

Decision framework

SituationProposed action
Historical statements do not reconcileResolve or clearly isolate the difference before using history as the forecast base.
The model balances through a plugIdentify the underlying linkage or classification error and restrict plugs to transparent, approved financing mechanics.
Circularity affects debt and interestUse a controlled circularity method or a documented approximation and test the effect.
A scenario changes cash needsTrace the effect through funding capacity, covenant headroom and the relevant transaction decision.

Common errors to check

  • Hard-coding forecast outputs that should flow from assumptions or schedules.
  • Treating a zero balance-sheet check as validation of the commercial forecast.
  • Mixing cash and non-cash items or inconsistent sign conventions.
  • Changing formulas across forecast periods without a documented reason and review.

Reconcile the integrated forecast

Bring the historical statements, operating assumptions, supporting schedules, debt terms and scenario requirements to a three-statement model review. Trace every material output through the statements and document unresolved model risks.
