Three-Statement Interview Questions Practice

Three-statement questions are the most reliably asked technical question in banking interviews, and they test whether you can trace one change through the income statement, cash flow statement, and balance sheet, not whether you can recite what each statement is. Depreciation, working capital changes, and debt draws are the three scenarios interviewers reach for most. This page is the practice set. For the base walkthrough, read how the three financial statements link together; here you'll drill ten fresh line-item changes plus three local reps.

TL;DR

• Use a fixed order every time: income statement, then cash flow statement, then balance sheet.
• The Trace-and-Check Method ends every answer with assets equal to liabilities plus equity.
• Depreciation lowers net income but raises cash, because it's a non-cash addback.
• Ten prompts below cover receivables, inventory, capex, and debt.
• The local pack checks three linked line-item changes without the full walkthrough as scaffolding.

What is the Trace-and-Check Method?

The Trace-and-Check Method is a fixed sequence that keeps you from skipping a statement mid-answer.

1. State the income statement effect first, even if it's zero. Many changes (like collecting a receivable) don't touch the income statement at all.
2. Move to the cash flow statement. State which section (operating, investing, financing) is affected and the sign.
3. Finish on the balance sheet. Identify both sides of the change: the account that moved and the offsetting account.
4. State one tax assumption whenever the income statement changes, since taxes affect how much of a pretax change flows through to cash and equity.
5. Check that assets still equal liabilities plus equity before you say you're done.

Worked example: a 100 depreciation increase, at a 25% tax rate

Prompt: Depreciation rises by 100 in the current period. Assume a 25% tax rate and no other changes.

Income statement: pretax income falls by 100, so net income falls by 100 times one minus the tax rate.

$$\Delta\text{Net income}=-100\times(1-0.25)=-75$$

Cash flow statement: start from net income (down 75), then add back the 100 of depreciation, since it's non-cash.

$$\Delta\text{Cash from operations}=-75+100=+25$$

Balance sheet: PP&E falls by 100 (the depreciation), cash rises by 25 (from the cash flow statement), and retained earnings falls by 75 (the after-tax net income change). Check both sides:

$$\Delta\text{Assets}=-100+25=-75, \quad \Delta\text{Liabilities}+\Delta\text{Equity}=0+(-75)=-75$$

Both sides fall by 75, so the balance sheet still balances. This is the single most commonly asked version of the three-statement question, and the tax rate is the detail candidates most often forget to apply.

Depreciation rises by 100 on the income statement. Walk through every line it touches.

Your answer

Reveal model structure

The pack above runs three more linked scenarios: a receivable collection, and a debt draw used to fund a dividend. Work through each one on paper before revealing the model answer.

Ten more three-statement prompts to practice

1. A company buys 200 of inventory for cash. What happens across the three statements? No income statement effect yet, since inventory isn't expensed until sold. Cash falls 200 on the cash flow statement (operating or investing depending on convention), and on the balance sheet, inventory rises 200 while cash falls 200; total assets are unchanged.
2. The company sells that inventory for 250, all on credit. What's the effect now? Revenue of 250 and cost of goods sold of 200 hit the income statement, for pretax income of 50. On the balance sheet, accounts receivable rises 250, inventory falls 200, and retained earnings rises by the after-tax net income. Cash flow shows the net income, adjusted for the still-uncollected receivable.
3. Capital expenditures of 150 are paid in cash, with no immediate income statement effect. How do the statements move? Cash flow statement shows a 150 outflow in investing activities. Balance sheet shows PP&E up 150 and cash down 150. The income statement is unaffected until depreciation begins.
4. A company writes off 40 of a bad debt (an account receivable it will never collect). What happens? An expense of 40 hits the income statement, lowering pretax income. Accounts receivable falls 40 on the balance sheet, and retained earnings falls by the after-tax effect. There's no cash flow impact in the period of the write-off itself, since the cash was never actually collected.
5. Accrued expenses (an expense recognized but not yet paid in cash) rise by 60. How does this flow? Pretax income falls 60 on the income statement. On the cash flow statement, the increase in accrued expenses is added back as a source of cash, since the expense reduced income without using cash yet. On the balance sheet, accrued liabilities rise 60 and retained earnings falls by the after-tax amount.
6. A company issues 300 of new equity for cash. What's the effect? No income statement impact. Cash flow statement shows a 300 financing inflow. Balance sheet shows cash up 300 and common equity up 300.
7. The company repurchases 100 of its own stock for cash. How do the statements move? No income statement impact. Cash flow statement shows a 100 financing outflow. Balance sheet shows cash down 100 and equity down 100 (treasury stock or a direct reduction, depending on convention).
8. Interest expense of 20 is paid in cash on outstanding debt. What happens across the statements? Pretax income falls 20 on the income statement. Cash flow from operations falls by the after-tax effect (interest is usually pretax on the income statement but affects net income after tax). Cash falls 20 on the balance sheet, with the offset in retained earnings.
9. A company draws 100 of new debt and uses it to buy equipment. What's the net effect on cash? None: the financing section shows a 100 inflow from the debt draw, and the investing section shows a 100 outflow for the equipment purchase, netting to zero on total cash.
10. An interviewer asks which statement you'd check first if the balance sheet doesn't balance. What do you say?** Check the cash flow statement's ending cash against the balance sheet's cash balance first, since a mismatch there usually points to a missed or double-counted line item flowing through incorrectly.

Line item and which statement it touches first

Frequently Asked Questions

Which statement should I start with in any answer?

The income statement, even when the answer is "no effect there." Stating that plainly shows you understand why some changes (like collecting a receivable) skip the income statement entirely.

What's the most common mistake candidates make?

Forgetting the tax rate on an income-statement change and applying the full pretax amount to cash flow or retained earnings, instead of the after-tax figure.

Do I need to worry about which cash flow section a change falls in?

Yes, roughly. Operating covers day-to-day items like receivables and payables, investing covers capex and long-term assets, and financing covers debt and equity issuance or repayment. Getting the section right shows you understand the mechanics, not just the sign.

How detailed should my balance sheet check be?

Detailed enough to name both sides of the change (which asset or liability moved and what offset it) and confirm assets still equal liabilities plus equity. You don't need to build a full model to prove it.

What if a change affects multiple periods?

State that explicitly. For example, capex hits the balance sheet immediately but only affects the income statement gradually through depreciation over the asset's useful life.

Is this the same as a full three-statement model?

No. A full model links formulas across a multi-year projection with growth assumptions and a cash flow sweep. This practice tests the mechanics of one change at a time, which is what interviewers actually ask.
