Net income

As explained in Investing for Programmers

Net income is the profit remaining after a company deducts expenses, interest, taxes, and other applicable charges from its income.

Net income is revenue minus expenses, indicating the profit or loss remaining for a period. Income statements report it for a quarter or year. section 2.1.1

Evaluate it across comparable periods rather than in isolation: seasonal businesses may depend heavily on Q4, while flat income loses real value over time through inflation. section 2.1.1

Use net income to frame practical questions:

• Is revenue and net income increasing over time? section 2.1.1
• Which expenses explain a significant change? section 2.1.1
• Does a reported increase reflect stronger operations or additional financing? section 2.1.1
