Final answer:
The term to describe the money remaining after subtracting all business expenses from gross revenue is 'net income'. Unlike gross income, net income includes all costs, and it aligns with the accounting profit concept.
Step-by-step explanation:
The term that describes the amount of money left over after all business expenses are subtracted from the gross revenue is net income.
Net income is different from gross income, which is the total revenue before expenses are deducted. The concept of net income is connected to accounting profit, which is defined as total revenues minus explicit costs, including depreciation.
Profit margin is another related term that refers to the average profit divided by the quantity of output produced. However, it's important to understand the distinction between accounting profit and economic profit. While accounting profit is total revenue minus explicit costs, economic profit considers both explicit and implicit costs.
