What is net income and why can it be misleading about a company's health?

Q: Why does net income not equal cash generated by a business?

Net income is accrual-based, including non-cash charges like depreciation and timing differences between revenue recognition and cash collection. A company can report positive net income while bleeding cash if customers aren't paying (A/R buildup), inventory is growing, or large capital expenditures drain the bank account. The cash flow statement reconciles this gap.

Q: What is the difference between book tax expense and cash taxes paid?

Book tax expense on the income statement is an accrual figure combining current and deferred tax components. Cash taxes are what the company actually pays the government. Differences arise from timing mismatches like accelerated depreciation, creating deferred tax assets (future benefit) or deferred tax liabilities (future obligation) on the balance sheet.

Q: How does net income connect to the other two financial statements?

Net income flows to the cash flow statement as the starting point for calculating cash from operations, where it is adjusted for non-cash items and working capital changes. It also flows to the balance sheet through retained earnings: ending RE equals beginning RE plus net income minus dividends. These connections create the integrated three-statement loop.

Q: What is the difference between EBIT and net income?

EBIT measures operating profitability before interest expense and income taxes, making it capital-structure neutral. Net income is what remains after all expenses including interest and taxes. Two companies with identical EBIT but different debt levels will show different net incomes. EBIT lets you compare operational performance; net income shows what shareholders actually earned.

"Earnings can be pliable as putty when a charlatan heads the company." — Warren Buffett

Concept

Net income is the final profit after subtracting all expenses from revenue. It's the literal bottom line of the income statement—what shareholders actually earned. This number flows into retained earnings on the balance sheet and serves as the starting point for the cash flow statement.

Intuition

Net income answers one question: Did the owners make money this period?

It's accrual-based, not cash-based. A company can report positive net income while bleeding cash (or vice versa).
It's after everyone else gets paid: suppliers, employees, landlords, lenders, government. Shareholders eat last.
It's the starting point for EPS, which drives stock prices. Miss consensus net income estimates and watch the stock crater.

Components

Gross Profit

What It Is

Revenue minus the direct costs of producing goods or services. Measures production efficiency before overhead.

How to Calculate It

Gross Profit = Revenue - COGS

COGS includes raw materials, direct labor, and manufacturing overhead—costs that scale directly with production.

Key Consideration

Gross margin varies wildly by industry. Software companies hit 70-80%. Grocery retailers scrape by at 20-25%. Always compare within industry.

Operating Income (EBIT)

What It Is

Profit from core business operations before financing decisions and taxes. Also called Earnings Before Interest and Taxes.

How to Calculate It

[EBIT](/readings/technical/accounting/ebit) = Gross Profit - Operating Expenses

Operating expenses include:

SG&A: Salaries, rent, marketing, admin
R&D: Research and development costs
D&A: Depreciation and amortization

Key Consideration

EBIT isolates operational performance. Two companies with identical EBIT but different capital structures will show different net incomes—EBIT lets you compare apples to apples.

Pre-Tax Income (EBT)

What It Is

Profit after accounting for interest expense but before the government takes its cut.

How to Calculate It

EBT = EBIT - Interest Expense + Interest Income

Highly leveraged companies show a big gap between EBIT and EBT. Cash-rich companies might actually add interest income here.

Key Consideration

EBT reflects capital structure choices. A company that levered up for an acquisition will show compressed EBT even if operations are strong.

Tax Expense

What It Is

Income taxes owed on reported earnings. Not the same as cash taxes paid.

How to Calculate It

Tax expense on the income statement is an accrual figure:

Tax Expense = Current Tax + Deferred Tax

Effective tax rate = Tax Expense ÷ Pre-Tax Income

Key Consideration

Book tax expense rarely equals cash taxes. Differences create deferred tax assets (you'll pay less later) or deferred tax liabilities (you'll pay more later). Accelerated depreciation is the classic driver.

Interview Script

Net Income is the final profit remaining after subtracting all expenses from revenue—it's literally the bottom line of the income statement and represents what shareholders actually earned. It's accrual-based, not cash-based, so a company can report positive net income while still burning cash. This number flows into retained earnings on the balance sheet, serves as the starting point for the cash flow statement, and drives EPS, which is why missing net income estimates can crater a stock.
