Reference Concepts
Tax Reference
Tax is the statutory charge on taxable profit after allowable deductions. It is now taught inside the combined PBT, Tax and PAT lesson, and remains here as a reference concept.
Concept First
Learn It Step By Step
Start with the business meaning, then move into the formula.
What is PAT?
PAT is the profit left after finance cost and tax. It is the profit base available to shareholders, subject to dividend and retention decisions. Example: final profit available to shareholders after all expenses, interest, and tax.
What is Profit Before Tax?
Profit after operating and finance costs but before tax. It connects operating performance to final PAT. Example: use the matching financial statement line item for the same period and keep the unit consistent before calculating.
How does the formula work?
PAT = Profit Before Tax - Tax. If a tax rate is used, Tax = PBT x tax rate.
How should I read the answer?
Tax affects the final profit available to shareholders and reinvestment.
Formula Lab
Understand the Formula
Read the formula like a business sentence before calculating it.
Formula
PAT = Profit Before Tax - Tax
Why this formula exists
Tax converts pre-tax profit into post-tax profit.
How it is derived
PAT = Profit Before Tax - Tax. If a tax rate is used, Tax = PBT x tax rate.
Simple example
If PBT is Rs. 100L and tax rate is 25%, tax is Rs. 25L and PAT is Rs. 75L.
Solved Case Study
Read the Numbers Like an Analyst
Work through one business case slowly: understand the situation, calculate the ratios, then interpret what the numbers are really saying.
Case context
If profit before tax is Rs. 10 Crore and tax is Rs. 2.5 Crore, PAT is Rs. 7.5 Crore.
1. Start with Profit Before Tax
Tax is calculated on taxable profit. In a simple P&L walkthrough, it bridges PBT to PAT.
2. Deduct tax from PBT
If PBT is Rs. 100L and tax rate is 25%, tax is Rs. 25L.
Tax explains the difference between pre-tax and post-tax profit.
3. Interpret carefully
A changing effective tax rate can affect PAT even when operating profit is stable.
Interpretation
What This Means In Practice
Read the result as a business signal, not as a standalone number.
How to read this
Tax affects the final profit available to shareholders and reinvestment. Start with the business meaning, then check the trend, peer benchmark, source line items, and cash impact.
What to remember
Tax is deducted after PBT to arrive at PAT. When comparing companies, check whether PAT is affected by unusual tax rates or one-time tax items.
Key Takeaway
Tax is deducted after PBT to arrive at PAT. When comparing companies, check whether PAT is affected by unusual tax rates or one-time tax items.
