Net profit or net incomes a measure of the profitability of a venture after accounting for all costs. In a survey of nearly 200 senior marketing managers, 91 percent responded that they found the "net profit" metric very useful. In accounting, net profit is equal to the gross profit minus overheads minus interest payable for a given time period (usually: accounting period).^{[citation needed]}

A common synonym for "net profit" when discussing financial statements (which include a balance sheet and an income statement) is the bottom line. This term results from the traditional appearance of an income statement which shows all allocated revenues and expenses over a specified time period with the resulting summation on the bottom line of the report.

In simplistic terms, net profit is the money left over after paying all the expenses of an endeavor. In practice this can get very complex in large organizations or endeavors. The bookkeeper or accountant must itemise and allocate revenues and expenses properly to the specific working scope and context in which the term is applied.
