How the statements link
The single most tested idea in a first-round interview.
- Net income and ending cash are the two links that carry across all three statements.
- A non-cash charge lowers profit but raises cash by the tax saved.
- Answer in the fixed order IS → CFS → BS and prove the balance.
The three joins
Net income flows from the income statement to the top of the cash flow statement and into retained earnings on the balance sheet.
Ending cash from the cash flow statement becomes the cash line on the balance sheet.
Depreciation reduces net income on the income statement and reduces net PP&E on the balance sheet, while being added back on the cash flow statement.
The classic walk-through
Depreciation rises by $10 with a 25% tax rate. Income statement: pre-tax income falls $10, net income falls $7.50.
Cash flow: start at −$7.50, add back the full $10 of depreciation, so cash rises $2.50 — the tax shield.
Balance sheet: cash +$2.50, PP&E −$10, so assets fall $7.50; retained earnings fall $7.50. It balances.
How to answer it out loud
Always in the same order: income statement, then cash flow statement, then balance sheet, and finish by saying the balance sheet balances.
Interviewers are listening for structure as much as arithmetic.
Apply the lesson to explain the single most tested idea in a first-round interview. Start with the answer, show the bridge, and sanity-check the direction before stopping.
- 1Lead with the definition or conclusion for how the statements link.
- 2Show the mechanics in a fixed sequence and state every assumption.
- 3Finish with the practical implication, risk, or reason the result matters.
Depreciation rises $20 at a 30% tax rate. What happens to cash?
Where does net income appear on the balance sheet?
- Net income and ending cash are the two links that carry across all three statements.
- A non-cash charge lowers profit but raises cash by the tax saved.
- Answer in the fixed order IS → CFS → BS and prove the balance.
