净赚 (jìng zhuàn) literally means 'pure earnings' — 净 (jìng) means 'net,' 'pure,' or 'after deductions,' and 赚 (zhuàn) means 'to earn' or 'to profit.' Together, they form a compound noun meaning 'net profit': the amount remaining after subtracting all costs, taxes, fees, and expenses from total revenue. It is commonly used in business, finance, personal budgeting, and informal discussions about income.

This term contrasts with 毛赚 (máo zhuàn) or more commonly 毛利润 (máo lìrùn), which refers to gross profit — revenue before deductions. 净赚 emphasizes what you actually keep, making it essential for accurate financial assessment. It appears frequently in reports, news articles about company performance, and everyday conversations when evaluating the real gain from a sale, investment, or side job.
