Net Income Formula
Net income is what remains after subtracting all expenses from total revenue, and the formula is total revenue minus the cost of goods sold, operating expenses, interest, and taxes. It is the bottom line of the income statement and represents the actual profit a business keeps over a period. Working down the income statement, revenue is reduced step by step by each category of cost until net income remains.
Problem & Application
Owner-operators often confuse cash in the bank with profit, but net income reflects all costs, including non-cash items like depreciation, that cash flow alone hides. For a campground or STR portfolio, a strong revenue month can still produce thin or negative net income once seasonal labor, utilities, financing, and taxes are accounted for. Computing it correctly is the foundation for margin analysis, tax estimates, and any valuation or financing conversation.
In Short
Net income is the single number that answers whether the business actually made money, and getting the inputs right makes every downstream metric reliable.
