In the business world, having a grasp on profitability encompasses much more than counting revenues; Profit After Tax (PAT) is one of the key financial metrics that truly reflects the actual profitability of a company, including the common financial term - "bottom line."
PAT serves as a basic number or figure that indicates how much net money a company has made after covering all its outlay expenses, including taxes. Investors, lenders, and stakeholders closely monitor this number to assess a company's operational performance, growth opportunities, and credit risk level better.
Before discussing its importance, it is essential to have a clear definition of PAT. The Profit After Tax reflects what is retained by a business after it has settled all of its liabilities, whether operational or non-operational, or tax expenses. Also known as Net Profit After Tax (NPAT) or Net Operating Profit After Tax (NOPAT), PAT is a direct measure of whether a company is truly profitable.
This statistic is important because it reflects the true earnings available to reinvest back in the business, distribute to shareholders, or retain as cash stock. PAT represents what a company is truly making after it has met and settled all of its liabilities.
Calculating profit after tax (PAT) is important for understanding a business's true profits and employs a fairly user-friendly accounting calculation. The most common computation is as follows: PAT = Net profit before tax (PBT) – total tax expense. PBT is the amount a company earns after deducting operating costs, interest, and other expenses (but before the income tax is applied). The total tax expense encompasses all taxes applicable, including income and corporate tax.
To illustrate, if PBT is - ₹50,00,000 and the total tax expense is ₹15,00,000, then: PAT = ₹50,00,000 – ₹15,00,000 = ₹35,00,000. That last amount, ₹35,00,000, is the company's net earnings — the bottom line — and is available to be either reinvested for future growth, distributed as dividends to shareholders, or included in the company's financial reserves.
To gain a clearer understanding of how Profit After Tax (PAT) is calculated for a company, let's consider a fictional example of a business.
Say the company generates total revenues of ₹1,00,00,000 and its total expenditures are ₹60,00,000. The expenditures could be COGS, depreciation expense, expenses such as rent, salaries, and utility bills, loan interest, research and development, and charge-offs.
You can then subtract the total expenditures from the total revenues, giving the Profit Before Tax (PBT):
₹1,00,00,000 - ₹60,00,000 = ₹40,00,000
Assuming the company has a tax liability of ₹10,00,000 (25%) the PAT can be calculated as follows:
₹40,00,000 - ₹10,00,000 = ₹30,00,000
This amount of ₹30,00,000 is the actual profit of the company after completing all its costs and tax liabilities. This is the profit the company can reinvest, pay dividends out of, or save.
Another important financial metric, in addition to PAT, is the Profit After Tax Margin — also referred to as Net Profit Margin.
This metric shows the percentage of revenue realised as profit after all expenses and taxes have been paid. It is an effective measure of how well the company controls its operating expenses and costs.
PAT is an important metric for measuring stakeholder profitability in financial analysis. It offers insight into current and historic tax efficiency and allows for performance comparability. It can also be analysed against relevant peers to assist in decision-making.
Profit After Tax (PAT) is the profit that an organisation keeps after it has deducted taxes, which include income tax, corporate taxes, or any other taxes from its total income.
PAT is an important metric of the organisation's ability to earn sustainable profits after meeting all obligations. Investors and creditors look to PAT as a straightforward measure of whether or not a business can be financially viable and profitable; thus, PAT is very important for financial decisions.
PAT is an important measure to evaluate the company's true profitability because it includes taxes. This is useful for stakeholders assessing the business's financial viability and overall performance.
PAT can be derived from net profit before tax minus total tax expense. Thus, mathematically speaking, the formula to express profit after tax is: PAT = Net Profit Before Tax - Total Tax Expense.
A positive PAT suggests a company can generate income after all its expenses; this means the company is financially stable or is able to generate a return to its shareholders.
PAT could be negative depending on the amount of business gross losses that exceed tax losses. There could be several reasons, such as high costs or decreasing income.
