In [[business]] and [[Accountancy|accounting]], '''net income''' (also '''total comprehensive income''', '''net earnings''', '''net profit''', '''bottom line''', '''sales profit''', or '''credit sales''') is an entity's [[income]] minus [[cost of goods sold]], expenses, [[depreciation]] and [[Amortization (accounting)|amortization]], [[interest]], and taxes, and other expenses for an [[accounting period]].<ref name="ias1">{{cite web |publisher=IFRS Foundation |year=2012 |title= IAS 1 Presentation of Financial Statements |access-date= April 14, 2012 |url=http://eifrs.ifrs.org/eifrs/bnstandards/en/2012/ias1.pdf }}</ref>{{Better source needed|reason=The current source does not obviously contain a definition.|date=August 2024}}

It is computed as the residual of all revenues and gains less all expenses and losses for the period,<ref name="swsf">Weil, Schipper, Francis. (2009) Financial Accounting: An Introduction to Concepts, Methods, and Uses. Cengage Learning</ref> and has also been defined as the net increase in [[Equity (finance)|shareholders' equity]] that results from a company's operations.<ref name="nnp">Weil, Schipper, Francis. (2010) Financial Accounting. Cengage Learning.</ref> It is different from [[gross income]], which only deducts the cost of goods sold from revenue.

For [[Household|households]] and individuals, '''net income''' refers to the (gross) income minus taxes and other deductions (e.g. mandatory [[pension]] contributions).

==Definition==
Net income can be distributed among holders of common stock as a [[dividend]] or held by the firm as an addition to [[retained earnings]]. As [[Profit (accounting)|profit]] and [[earnings]] are used synonymously for [[income]] (also depending on UK and US usage), '''net earnings''' and '''net profit''' are commonly found as synonyms for net income. Often, the term '''income''' is substituted for net income, yet this is not preferred due to the possible ambiguity. Net income is informally called the '''bottom line''' because it is typically found on the last line of a company's [[income statement]] (a related term is [[top line]], meaning [[revenue]], which forms the first line of the account statement).

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. 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.

Net income is usually calculated per annum, for each [[fiscal year]]. The items deducted will typically include [[tax expense]], financing expense ([[interest expense]]), and minority interest. Likewise, 
[[preferred stock]] dividends will be subtracted too, though they are not an expense. For a [[Merchandising (play)|merchandising]] company, subtracted costs 
may be the [[cost of goods sold]], sales discounts, and sales returns and allowances. For a product company, [[advertising]], 
[[manufacturing]], & design and development costs are included. Net income can also be calculated by adding a company's operating income to non-operating income and then subtracting off taxes.<ref name="nbp">{{cite web|url=http://newbusinessplaybook.com/net-income-formula/|title=Net Income Formula|publisher=New Business Playbook|archive-url=https://web.archive.org/web/20131019070557/http://newbusinessplaybook.com/net-income-formula/|archive-date=2013-10-19|url-status=usurped}}</ref>

The net [[profit margin]] percentage is a related ratio. This figure is calculated by dividing net profit by revenue or turnover, and it represents profitability, as a percentage.

==An equation for net income==
Net profit: To calculate net profit for a venture (such as a company, division, or project), subtract all costs, including a fair share of total corporate overheads, from the gross revenues or turnover.<ref>{{cite web |title=Gross Profit vs. Net Income: What's the Difference? |url=https://www.investopedia.com/ask/answers/101314/what-are-differences-between-gross-profit-and-net-income.asp |publisher=Investopedia}}</ref>

<math>\text{Net Profit} = \text{Sales Revenue} - \text{Total Costs}</math>

A detailed example of a net income calculation:

<math>\text{Net Income} = \text{Gross Profit} - \text{Operating Expenses} - \text{Other Business Expenses} - \text{Taxes} - \text{Interest on Debt} + \text{Other Income}</math>

Net profit is a measure of the fundamental profitability of the venture. "It is the revenues of the activity less the costs of the activity. The main complication is . . . when needs to be allocated" across ventures. "Almost by definition, overheads are costs that cannot be directly tied to any specific" project, product, or division. "The classic example would be the cost of headquarters staff." "Although it is theoretically possible to calculate profits for any sub-(venture), such as a product or region, often the calculations are rendered suspect by the need to allocate overhead costs." Because overhead costs generally do not come in neat packages, their allocation across ventures is not an exact science.<ref name="Marketing_Metrics2">Farris, Paul W.; Neil T. Bendle; Phillip E.

=== Example ===
Net profit on a P & L (profit and loss) account:

# [[Sales revenue]] = price (of product) × quantity sold
# [[Gross profit]] = sales revenue − cost of sales and other direct costs
# Operating profit  = gross profit − overheads and other indirect costs
# [[Earnings before interest and taxes|EBIT]] (earnings before interest and taxes) = operating profit + interest income + other non-operating income
# [[Earnings before taxes|EBT]] (Pretax profit, earnings before taxes) = EBIT − interest expenses − other non-operating expenses
# Net profit = EBT − tax
# [[Retained earnings]] = Net profit − dividends

Another equation to calculate net income:

[[Net sales]] (revenue) - [[Cost of goods sold]] = [[Gross profit]] - [[SG&A]] expenses (combined costs of operating the company) - [[Research and development]] (R&D) = [[Earnings before interest, taxes, depreciation and amortization]] (EBITDA) - [[Depreciation]] and [[amortization (accounting)|amortization]] = [[Earnings before interest and taxes]] (EBIT) - [[Interest expense]] (cost of borrowing money) = [[Earnings before taxes]] (EBT) - [[Tax expense]] = Net income (EAT)
