It is what you have left after everything has been taken out, such as expenses, taxes, depreciation, and other costs, from total revenue.
This guide covers what net income is, how it’s determined, the net income formula, and the significance of net income in corporate and personal finance.
What Is Net Income?
Net income (NI) is more appropriately called profit after tax is the dollar amount remaining to a business or individual after all expenses have been subtracted from revenue. DOWN FOR BUSINESS, that is: operating expenses, cost of goods sold (COGS), debt interest, and tax. For people, it is usually what remains of gross salary after income tax and deductions have been calculated.
It is a key metric that determines profitability and sustainability. The term bottom line refers to the fact that it appears at the bottom of the income statement where it has a direct effect on the financial decision making, business valuations and shareholder returns.
Why Is Net Income Important?
Understanding your net income prevents decision making from becoming a case of wishing you had something else. For businesses, it acts as a major contributor.
- Assessing the efficiency of operations
- Deciding dividend payouts
- Measuring the performance of investments
- Taxes and reporting requirements having to file tax returns

Additionally, net earnings is closely monitored by investors and stakeholders as a guide for a company’s potential for profitability and long-term value.
Understanding the Net Income Formula
Basic net income equation because knowing how you cannot arrive at your final profit is fundamental for knowing how to calculate it. Although other industries may have a slightly different method for calculating it, the basic structure is consistent:
The formula for Net Income is simply Total Revenue – Total Expenses.
Below is a more detailed version, one through the lens of the complexities of a business:
Net Profit = Revenues − (COGS + Operating Expenses + Interest + Taxes + Depreciation & Amortisation)
What this equation shows is that net income is much more than just taking away business costs. It even takes into account depreciation and taxes, which are critical components in assessing actual profitability.
You never have to commit these formulas to memory when thinking of using finance in everyday life but understanding how the various components relate to each other should give you greater clarity when reading financial statements or when budgeting.
Components That Influence Net Income
Knowing the components that comprise the equation helps us articulate how to compute NI. Note that each of these can have a sizeable effect on your bottom line:
Revenue (Sales/Income)
This is the first calculation to start with. Revenue represents all money generated from core company operations for example, the sale of goods; service fees; subscriptions; or licensing. It can also include passive income also Interest income.
Cost of Goods Sold (COGS)
These refer to the costs of the direct raw materials and labour involved in creating any goods or services that the company sells. Includes costs of raw materials, manufacturing, and direct labour. With COGS increasing, that means less of an opportunity for gross profit and thus a lower net income.
Operating Expenses
These are the overheads such as rent, payroll, utilities, supplies, and other costs of doing business. Doing it right could influence positively your bottom line.
Interest and Taxes
Businesses tend to be capitalised with debt, where interest payments are subtracted from revenue. The impact of taxes corporate tax for businesses or income tax for individuals on profit after tax is significant.
Depreciation and Amortisation
These are non-cash expenses for the depreciation of tangible assets and amortisation of intangible assets. They are not cash flow items, but they lower taxable income, and influence how businesses report profit.
How to Calculate NI for a Business
So now, practical NI calculation example with Ninja formula will help you to understand how these numbers come together.
Let us consider a company with the following financial year figures:
- Total Revenue: AUD 500,000
- COGS: AUD 200,000
- Operating Costs: AUD 120,000
- Interest Expense: AUD 10,000
- Taxes: AUD 30,000
- Depreciation& Amortisation AUD 15,000
Net Income Formula: Here we have used the equation of net income,
- Profit = 500,000 − (200,000 + 120,000 + 10,000 + 30,000 + 15,000)
Therefore, the Net Income = 500,000 – 375,000 = 125,000 AUD.
For a Company Net Profit of $125,000 after all costs & expenses
Individual NI Calculation Explained
This blog is primarily focused on businesses, but individuals also gain from awareness of NI calculation. When it comes to individuals, net income is usually your post-deduction income.
Example:
You are on a gross annual salary of AUD 85,000. Your deductions after your superannuation contributions, income tax and Medicare levy total AUD 20,000.
Your net income will be:
Gross Income = 85,000 — 20,000 = AUD 65,000
That is your actual spendable money for the year. Once you understand this, you can create a better personal budget, track your savings and plan your debt repayments or investments.
What Reduces Net Income?
Various determinants can diminish the profits, post taxation of your enterprise, but this is something that gives high concern to a firm and requires continuous monitoring to maintain healthy bottom lines.
- Higher manufacturing costs or supply chain logistics discomfort
- Added overheads like rent or salaries without similar revenue growth.
- High interest on loans could eat into your profits – debt servicing
- Changes in regulation or taxation that raises taxes payable
- Asset depreciation (manufacturing, transport-intensive industries)
Net Income vs. Gross Profit vs. Operating Income
One area that regularly confuses investors is differentiating between gross profit, operating income, and net income. So, in simpler terms,
Gross Profit = Revenue – COGS
This is prior setting aside overheads or taxes. It indicates the efficacy of production.
Operating Income = Gross Profit -Operating Expenses
This shows how well your core operations are doing before financing and tax decisions are made.
Net Income=(Operating Income)-(Interest+Taxes+Depreciation)
This is the most accurate gauge of the company’s true income.
By knowing these layers, you will make smarter judgments when reading income statements and you will evaluate business performance more effectively.
Limitations of Net Income
Net earnings, however, cannot be viewed in isolation. Investors and financial analysts frequently complement them with other metrics such as EBITDA (Earnings Before Interest, Taxes, Depreciation, and Amortisation), free cash flow, and operating cash flow to make a broader assessment.
And net income has also been affected by some one-off events such as asset sales or write-downs, should not be a good representation of regular operating performance.
NI Calculation Example for a Services-Based Business
Let’s take another example of NI, this time for a services business, say a marketing agency:
- Service Revenue Per Annum: AUD 300,000
- Staff Salaries: AUD 120,000
- Office Rent: AUD 25,000
- Software and Tools – AUD 10,000
- Insurance & Admin: AUD 5,000
- Tax & Superannuation: $30,000
There are no physical assets to write down
- Net Income = 300,000 − (120,000 + 25000 + 10,000 + 5,000 + 30,000)
- Net Profit = 300k −190k = AUD 110,000
This shows the steady margins with sensible operational costs which indicates a sustainable business.
