What it means
An income statement works downwards. Revenue at the top, then the cost of delivering the product, then operating expenses, then interest on borrowings, and finally tax, with net income after taxes as what survives at the bottom.
The figure matters because it is the pool from which almost everything else is funded. Dividends are paid out of it, retained earnings grow by it, and share-based valuation measures such as the price to earnings ratio divide the share price by a per-share version of it.
Managers use it to judge whether the whole machine works, not just one part. A company can have excellent gross margins and still report thin net income if overheads are bloated, borrowing is expensive or its tax position is unfavourable.
The most important nuance is that net income is an accounting measure, not a cash measure. It includes non-cash charges such as depreciation and recognises revenue when it is earned rather than when customers pay, so a profitable company can still be short of cash and a loss-making one can be flush with it.
The tax line also deserves attention because the effective rate a company actually pays rarely matches the headline statutory rate. Allowances, prior-year losses and profits earned in different countries all pull it around, so comparing bottom lines without glancing at the tax charge can be misleading.
In practice
Real-world examples.
Example
A dental practice group reports operating income of $1,800,000 and interest costs of $200,000, giving pre-tax income of $1,600,000. Tax at 24% is $384,000, so net income after taxes is $1,216,000, and the partners use that figure to set the annual distribution.
Example
A listed engineering firm reports net income after taxes of $42,000,000 with 30,000,000 shares in issue, producing earnings per share of $1.40. Analysts apply a multiple to that per-share figure when publishing their target prices.
Example
A franchise owner compares two outlets that each generate $900,000 of revenue. One returns net income after taxes of $81,000 and the other $18,000, and the gap turns out to be rent and manager pay rather than anything to do with sales.
Formula
Calculation
Net Income After Taxes = Pre-Tax Income - Income Tax Expense
A speciality coatings company reports revenue of $8,000,000 for the year. Cost of goods sold is $4,600,000, leaving gross profit of $8,000,000 - $4,600,000 = $3,400,000.
Operating expenses covering salaries, marketing, rent and depreciation total $2,000,000, so operating income is $3,400,000 - $2,000,000 = $1,400,000. Interest on its bank loan costs $150,000, giving pre-tax income of $1,400,000 - $150,000 = $1,250,000.
Income tax at an effective rate of 24% is 0.24 x $1,250,000 = $300,000. Net income after taxes is therefore $1,250,000 - $300,000 = $950,000, which against revenue of $8,000,000 is a net profit margin of $950,000 / $8,000,000 = 11.9%.Case study
Seen in the real world.
Beacon Hill Instruments is a fictional business and this case is purely illustrative. In its first reported year it earned revenue of $12,000,000 and net income after taxes of $1,440,000, a net margin of 12.0% that the board treated as the benchmark for everything that followed.
The next year revenue grew 20% to $14,400,000, yet the bottom line went backwards. A disputed supply contract ended in an $800,000 settlement charge, which pulled pre-tax income down to $1,300,000. Tax at an effective rate of 26% was $338,000, leaving net income after taxes of $962,000 and a net margin of about 6.7%.
Rather than accept the headline, the finance director showed the board what the year looked like without the one-off item. Pre-tax income would have been $1,300,000 + $800,000 = $2,100,000, tax would have been $546,000, and net income after taxes would have reached $1,554,000, comfortably ahead of the prior year. The board approved the growth plan and asked for the settlement to be disclosed separately so that future comparisons stayed honest.
Watch out
Common mistakes.
- Treating net income after taxes as the cash the business generated, when depreciation, credit sales and capital spending all drive a wedge between profit and cash.
- Assuming the tax charge equals the headline corporate rate multiplied by pre-tax income, ignoring allowances, losses and overseas rates.
- Judging management on the bottom line alone in a year when a single disposal, write-off or settlement dominates the result.
Questions
People also ask.
Is net income after taxes the same as net profit?
Yes, the terms are used interchangeably, along with net earnings and the bottom line.
Why does net income differ from cash flow?
Because accounting recognises revenue and expenses when they are earned or incurred, and includes non-cash charges, while cash flow only counts money actually moving.
Can a profitable company still run out of cash?
Yes, and it happens most often to fast-growing businesses that must pay suppliers and staff long before customers settle their invoices.
