Revenue (also called top-line or turnover) is the total money the company received from customers in a period.
Profit (or net income, bottom-line) is what's left after paying employees, suppliers, interest, taxes and everything else.
A company can grow revenue quickly but still lose money — think of a startup burning cash to acquire users.
Analogy: a tea stall makes ₹5,000/day (revenue). After paying for milk, sugar, cups, LPG, rent and helper's salary, ₹800 is left — that's profit. Big revenue doesn't mean much if profit is thin.
