What is net income?
Net income (also known as net profit – or simply profit) is the amount of money remaining in a business after subtracting all expenses from its total revenue, including:
- All operating costs
- Any interest on debt
- Required taxes
- Any other business expenses
In the simplest terms, net income is the “bottom line” profit after every expense is paid.
A business that has a positive net income is, of course, profitable. A business with negative net income, however, is running at a loss, meaning that their expenses are higher than their revenue.
Why is net income important for a business?
Net income is more than just a number on a financial statement. We have listed some of the top ways it can influence a business below:
It helps to assess and measure profitability
Net income can show exactly how profitable a business is once all costs are accounted for. Overall revenue can look impressive, but net income shows the real result.
It helps to support cash flow planning
A consistently strong net income helps to support a healthy cash flow as it provides better financial stability. It makes it much easier to meet the day-to-day requirements of a business, like paying employees and bills.
It can guide important financial decisions
Net income is used to guide business decisions, for example knowing when and where to reinvest. It guides hiring, expanding, and so much more. Strong net income can also lead to better financing options.
Instilling investor confidence
Investors have a vested interest in monitoring a business’ net income. Those that have consistent positive net income are more likely to deliver returns, which can also lead to attracting new investors.
It can act as a benchmark for comparison over time
Net income makes it so much easier to compare financial performance over months, quarters, or years. It’s also a useful way to track progress against industry benchmarks and internal goals.
How to calculate net income
In order to calculate net income, you need to subtract all business expenses from your total revenue for a specific period of time. Here’s how to get started:
Step 1: Gather your financial records
You’ll need to gather your income statement (profit and loss statement). A cash flow statement can also help in giving an overall picture with more accuracy.
Step 2: Calculate your total business revenue
Total revenue is the amount of income made from your business, and can sometimes include additional income sources if required in your report.
Step 3: List any expenses
Expenses can include rent, payroll, and any other payments made throughout the accounting period.
Step 4: Include any interest
If your business pays interest on outstanding debt, add that to your expense total.
Step 5: Subtract any taxes
Deduct all taxes from your overall revenue. These amounts will vary based on your specific business structure and local regulations.
Step 6: Calculate net income
Once everything is collected, use the net income formula:
Net Income = Total Revenue – Operating Expenses – Interest Expenses – Income Taxes
Step 7: Review what the numbers mean
In simple terms, a positive net income will show that your business has made a profit. A negative number will show that your business has run at a loss.
Step 8: Analyse and improve
Once this process is complete, you can use the information gathered to make better business decisions. It can help your budgeting and forecasting, and can lead to future growth. It becomes more and more valuable when tracked consistently over time.
Net income formula
The basic net income formula is:
Net Income = Total Revenue – Total Expenses – Taxes
- Total revenue: all income generated throughout a period of time
- Total expenses: all operating costs and business expenses paid
- Taxes: all taxes owed for the period of time
Net income examples
Here are two simple examples:
Example 1: Positive net income
- Total revenue: £300,000
- Total expenses (including interest): £150,000
- Taxes: £20,000
Net income = £300,000 − £150,000 − £20,000 = £130,000
We can see that this business made a profit of £130,000.
Example 2: Negative net income
- Total revenue:£50,000
- Total expenses: £70,000
- Taxes: £0
Net income = £50,000 − £70,000 − £0 = −£20,000
This business recorded a £20,000 loss.
Are there any net income limitations?
Net income is a fantastic metric for understanding your business, but it does have a few limitations to consider.
It’s based on accrual accounting
Net income is often calculated using accrual accounting, which is when revenue and expenses are recorded only when earned or incurred – not when the cash is actually received. This can create gaps between profit and cash availability.
It’s includes non-cash expenses
Depreciation and amortisation reduce net income, even though they don’t represent real cash leaving the business.
It’s doesn’t use real-time information
Net income is usually reported monthly, quarterly, or annually. That makes it less useful for day-to-day decision-making without additional financial tracking.
Taxes can fluctuate
Tax credits and deductions are two things that can influence income tax, which can cause net income to vary from one period to the next.
Businesses can be affected by inflation and exchange rates
For companies that operate internationally, currency movements and inflation can affect the real value of net income over time.
Because of these limitations, many businesses opt to track other financial metrics like cash flow, EBITDA, and profitability ratios.
How to use net income in financial decision making
Once you know your net income, you can use it as a starting point for smarter financial planning. It can help with:
- Creating budgets and future forecasts
- Evaluating whether or not current expenses are sustainable
- Strengthening loan applications and improving financing options
- Estimating tax liabilities
- Compare profitability against competitors or industry averages
When tracked consistently, net income is the clearest indicator of long-term business performance.

Net income FAQs
Gross income vs net income
The difference between gross income and net income comes down to one thing – what has been deducted.
Gross income is the total revenue earned before subtracting any costs. For a business, this means that any cash generated from sales, without accounting for any expenses.
Net income, on the other hand, is what remains after all expenses are deducted, including operating costs. As this metric reflects the true amount of profit leftover, it is considered a more reliable measure of profitablity.
