When you read a company’s earnings report and see a headline like “Net profit rises 18% to ₹4,200 crore” — that number is PAT. It is one of the most watched figures in finance, yet many people are unsure exactly what it means, how it is calculated, and why it matters.
This guide explains PAT in plain English, with a clear formula, worked examples, and practical advice on how to use it when evaluating a business or investment.
What does PAT mean?
PAT stands for Profit After Tax. It is the net profit a company retains after paying all its expenses — including operating costs, interest on debt, depreciation, and most importantly, income tax.
PAT is also commonly referred to as:
- Net profit
- Net income
- Bottom line (because it appears at the bottom of the income statement)
In simple terms: PAT is what a company actually keeps after the government has taken its share. It is the truest measure of a company’s profitability.
PAT formula
The formula for PAT is straightforward:
Or more commonly expressed as:
Where PBT is Profit Before Tax — the profit a company earns before the tax deduction is applied.
PAT vs PBT vs EBITDA — what is the difference?
These three terms appear constantly in financial reporting. Here is how they compare:
| Term | Full form | What it excludes | Best used for |
|---|---|---|---|
| EBITDA | Earnings before interest, tax, depreciation & amortisation | Interest, tax, D&A | Comparing operational efficiency |
| PBT | Profit before tax | Tax only | Understanding pre-tax profitability |
| PAT | Profit after tax | Nothing — all deductions included | True bottom-line profitability |
PAT is the most complete profitability measure because nothing has been left out. It is what shareholders and investors actually care about.
A simple example of PAT calculation
Let us take a fictional company, Sunrise Retail Ltd, and calculate its PAT step by step.
| Line item | Amount (₹ crore) |
|---|---|
| Revenue | 500 |
| Less: Operating expenses | 300 |
| Less: Depreciation | 20 |
| Less: Interest | 30 |
| Profit Before Tax (PBT) | 150 |
| Less: Tax (@ 25%) | 37.5 |
| Profit After Tax (PAT) | 112.5 |
So Sunrise Retail Ltd earned a PAT of ₹112.5 crore on revenue of ₹500 crore — a PAT margin of 22.5%.
What is PAT margin and why does it matter?
PAT margin (also called net profit margin) tells you what percentage of revenue a company keeps as profit after all deductions. It is calculated as:
A higher PAT margin means the company is more efficient at converting revenue into actual profit. Here is a rough benchmark across industries:
| Industry | Typical PAT margin |
|---|---|
| IT / Software | 15% – 25% |
| FMCG | 10% – 18% |
| Banking | 15% – 25% (on NII basis) |
| Retail | 3% – 8% |
| Manufacturing | 5% – 12% |
Always compare PAT margins within the same industry — a 5% margin is weak for a software company but perfectly healthy for a supermarket chain.
What is PAT growth and why investors track it
PAT growth refers to the year-on-year increase in a company’s net profit. It is one of the most closely watched signals by equity analysts and retail investors alike.
For example, if a company’s PAT was ₹100 crore last year and ₹130 crore this year, its PAT growth is 30%.
Consistent PAT growth over multiple years is one of the strongest indicators of a fundamentally healthy business. It suggests the company is not just growing revenue but also managing costs and taxes effectively.
Limitations of PAT as a metric
PAT is powerful, but not perfect. Here are situations where it can be misleading:
- One-time gains: A company may show high PAT in a year because it sold a factory or received an insurance payout. This inflates profit without reflecting real business performance.
- Deferred tax benefits: Tax credits or deferred tax assets can temporarily boost PAT without real operational improvement.
- Accounting adjustments: Depreciation methods and inventory valuation can significantly affect PAT without any change in cash flows.
This is why experienced investors look at PAT alongside other metrics like free cash flow, return on equity (ROE), and EBITDA to get the full picture.
PAT in business vs PAT in finance — is there a difference?
Not really. Whether you are discussing a startup, a listed company, or a multinational corporation, PAT means the same thing: net profit after all taxes have been deducted. The term is used interchangeably in business reporting, equity research, and financial analysis.
The only slight difference in usage is context. In business discussions, PAT is often used to judge the health of a single company. In finance and investing, PAT is compared across companies, sectors, and time periods to identify trends and opportunities.
How to find PAT in a company’s financial statements
PAT appears on the income statement (also called the profit and loss statement or P&L). It is always the last line — which is why it is called the “bottom line.” For Indian listed companies, you can find the income statement in:
- The company’s quarterly or annual results filed with BSE/NSE
- The investor relations section of the company website
- Financial data platforms like Screener.in, Moneycontrol, or Tickertape
The bottom line
PAT — Profit After Tax — is the clearest, most complete measure of how much money a business actually makes. It strips away every cost, every expense, and every tax obligation to show you what is truly left. Whether you are reading a company’s annual report, comparing investment options, or studying for a finance exam, understanding PAT is non-negotiable.
The next time you see a headline about a company’s earnings, you will know exactly what that number represents — and more importantly, what questions to ask beyond it.
