Key takeaways

• Calculate NOPAT by multiplying your operating profit by (1 minus your tax rate) to measure how much profit your business earns from core activities after taxes but before interest expenses.
• Use NOPAT to compare businesses with different debt levels fairly, as it excludes financing costs and reveals true operational performance regardless of how companies fund their operations.
• Apply NOPAT as a key input for calculating Economic Value Added (EVA) to determine whether your business generates returns above its cost of capital and creates real economic value.
• Focus on operating profit from core business activities when calculating NOPAT, excluding non-operating income like investment gains or rental income from assets unrelated to your main business.

What is NOPAT?

Net Operating Profit After Tax (NOPAT) measures how much profit your business earns from its core activities, after tax but before interest. This metric excludes income and expenses unrelated to your main operations, giving you a clear view of operational profitability. New accounting standards highlight the importance of this distinction by requiring companies to present operating profit as a defined subtotal, designed to improve financial reporting.

NOPAT focuses specifically on operational earnings. Here's what it includes and excludes:

• Includes: profit from core business activities after taxes
• Excludes: interest expenses on loans, credit cards, or other debts
• Excludes: non-operating income like investment gains or rental income

The NOPAT formula helps you calculate the return you're getting from invested capital, making it essential for evaluating business investments and comparing operational performance.

Why is NOPAT important?

NOPAT reveals operational profitability regardless of debt levels. This makes it valuable for:

• comparing businesses across different regions or industries
• evaluating how efficiently a business generates returns on invested capital
• assessing performance independent of financing decisions

Reveals true business performance

By excluding financing costs, NOPAT shows you how the business performs operationally while accounting for its tax burden. This is especially useful when evaluating businesses with complex financial structures or multiple investors, helping you identify areas to improve and decide about long-term growth.

Helps to standardise comparisons

NOPAT standardises comparisons between companies with different debt levels and tax situations. If a business carries heavy debt, its net profits may look low even when operations are strong. For example, one analysis shows a company with heavy debt appearing to have $0 net income, while its after-tax operating profit was actually $79,000. NOPAT strips away these financing costs so you can focus on core operational health.

Here's an example: You're comparing two businesses to buy. Company A shows $100,000 in net profit. Company B shows $80,000 in net profit but carries significant debt. Exclude Company B's interest payments, and its operational profit jumps to $120,000. NOPAT reveals Company B's true potential if you restructure its loans.

Improved decision-making

NOPAT improves decision-making by showing how invested capital performs. It's a key input for calculating Economic Value Added (EVA), which measures whether a business generates returns above its cost of capital. Calculating EVA can be complex, as determining its value often requires making adjustments to GAAP accounting to get a true picture of economic profit.

EVA formula: NOPAT − (Total Invested Capital × Cost of Capital)

Example calculation:

• NOPAT: $50,000
• Invested capital: $200,000 (loans at 6% + cash investment)
• Average cost of capital: 3%
• EVA: $50,000 − ($200,000 × 3%) = $44,000

This means your $200,000 investment generates $44,000 above its cost of capital each year. EVA is especially useful for businesses with multiple shareholders, helping them decide about future investing or financing.

NOPAT formula explained

The NOPAT formula is straightforward once you understand its components.


Simple NOPAT formula

NOPAT = Operating Profit × (1 − Tax Rate)

Start with operating profit (earnings after all operating expenses, including depreciation and amortisation, but before taxes or interest). Multiply by the portion you keep after taxes.

Example: If your tax rate is 20%, multiply operating profit by 0.80 to get NOPAT.

Detailed NOPAT formula

If you don't have operating profit readily available, calculate it from revenue:

NOPAT = (Revenue − COGS − Operating Expenses − Depreciation − Amortisation) × (1 − Tax Rate)

Note: Operating profit differs slightly from EBIT (earnings before interest and tax). EBIT includes all income sources, while operating profit only includes income from your main business activities.

How to calculate NOPAT

Follow these steps to calculate NOPAT for your business or any company you're evaluating.

1. Determine operating profit

First, determine your operating profit. This is your earnings from core business activities before taxes and interest.

Calculate operating profit: Revenue − Cost of Goods Sold − Operating Expenses = Operating Profit

Don't include non-operating income like investment gains or rental income from non-core assets.

1. Find the tax rate

To find your effective tax rate, divide the income tax paid by your pre-tax income.

Effective Tax Rate = Income Tax Paid ÷ Pre-Tax Income

Example: If pre-tax income was $100,000 and you paid $20,000 in tax, your effective rate is 20%.

If you expect higher earnings this year, recalculate to account for how your tax bracket might change.

1. Apply the formula

Apply the formula using your numbers:

Sample calculation:

• Operating profit: $50,000
• Tax rate: 25%

NOPAT = $50,000 × (1 − 0.25) = $37,500

This means your core business operations generate $37,500 in profit after taxes, before accounting for any interest on debt.

NOPAT calculation examples

These examples show how the formula works in practice. Here are a couple of examples for different types of small businesses.

Example 1: Small retail business

Imagine a local bookstore wants to check its operational health.

• Revenue: $200,000
• Cost of goods sold: $120,000
• Operating expenses (rent, salaries): $50,000
• Tax rate: 20%

First, find the operating profit: $200,000 - $120,000 - $50,000 = $30,000.

Next, apply the NOPAT formula: $30,000 x (1 - 0.20) = $24,000.

The bookstore's NOPAT is $24,000, showing its core business profitability after taxes.

Example 2: Service-based business

Now consider a freelance graphic designer.

• Revenue: $90,000
• Operating expenses (software, marketing): $20,000
• Tax rate: 25%

First, find the operating profit: $90,000 - $20,000 = $70,000.

Next, apply the NOPAT formula: $70,000 x (1 - 0.25) = $52,500.

The designer's NOPAT is $52,500. This figure is useful for comparing their operational efficiency year over year.

When to use NOPAT

NOPAT is most useful in specific situations.

Use NOPAT for:

• Comparing businesses with different debt levels, as it removes financing costs for a true side-by-side look at operations
• Evaluating a potential business to buy, as it shows you the underlying profitability before you decide how to finance the purchase
• Benchmarking your performance to see how your operational efficiency stacks up against competitors, regardless of their financial structure
• Assessing your own improvements to track whether changes in your business operations boost your bottom line over time

NOPAT vs net income

Net income includes all business income, expenses, and taxes. NOPAT excludes interest expenses and non-operating income, focusing only on core operations. In one real-world example, a company with Net Earnings of $2,474 had a much higher NOPAT of $4,195, highlighting the difference in what each metric measures.

Key differences:

• Net income: accounts for operating expenses, interest, depreciation, amortisation, taxes, and all side income
• NOPAT: excludes interest payments and income from non-core activities like investments or rentals

Example: A bakery has $100,000 in net income, including $12,000 from renting parking space and $8,000 in loan interest. To find NOPAT, exclude both the rental income (non-core) and interest. NOPAT = $80,000.

If a business has no debt and no side income streams, NOPAT and net income are the same.

Operating profit vs NOPAT

Operating profit and NOPAT both measure earnings from core operations before interest. The key difference: operating profit excludes taxes, while NOPAT includes them.

Relationship: Operating Profit = NOPAT + Taxes

Example: If NOPAT is $80,000 and tax liability is $16,000, operating profit equals $96,000.

FAQs on NOPAT

Here are answers to common questions about net operating profit after tax.

Is NOPAT the same as EBIT?

No, they're different. EBIT stands for earnings before interest and tax. NOPAT is calculated after taxes. If a business has no non-operating income, you can find NOPAT by multiplying EBIT by (1 - tax rate).

How is NOPAT different from free cash flow?

NOPAT measures operational profit, while free cash flow (FCF) measures the actual cash a business generates. A company can have a high NOPAT but low FCF if it's spending a lot on new equipment or inventory.

Why use NOPAT instead of net income?

Use NOPAT to compare the core operational performance of companies without the influence of their debt levels. Net income includes interest payments, which can make a company with high debt appear less profitable than one with no debt, even if its operations are stronger.
