Key takeaways

• Calculate NOPAT using the simple formula: Operating profit × (1 - Tax rate) to measure your core business profitability after taxes but before interest expenses.
• Use NOPAT to compare businesses with different debt levels fairly, as it excludes interest payments and focuses purely on operational performance rather than financing decisions.
• Apply NOPAT in Economic Value Added calculations to determine if your business creates value beyond its cost of capital by subtracting the cost of invested capital from NOPAT.
• Exclude non-operating income like investment gains and rental income when calculating NOPAT to get an accurate view of your core business operations.

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. It excludes non-operating income (like investment gains) and interest expenses on debt, focusing purely on operational performance.

NOPAT helps you understand true operational profitability by excluding financing decisions. Here's what it includes and excludes:

• includes: revenue and expenses from core business operations, corporate taxes
• excludes: interest payments on loans or credit cards, investment gains or losses, income from non-core activities

This makes NOPAT useful for calculating return on invested capital and comparing businesses with different debt levels.

Why is NOPAT important?

NOPAT shows operational profitability independent of financing decisions. NOPAT is valuable because it helps you:

• compare businesses fairly by evaluating companies with different debt levels on equal footing
• assess cross-border performance by seeing how tax rates in different regions affect profits
• calculate investment returns by measuring how effectively invested capital generates earnings

Reveals true business performance

NOPAT isolates operational performance by removing interest expenses while including taxes. This gives you a realistic view of how the core business performs, separate from how it's financed.

For businesses with complex capital structures or multiple investors, NOPAT helps identify operational strengths and weaknesses without debt distorting the numbers.

Helps to standardise comparisons

NOPAT standardises comparisons by stripping out debt-related distortions, a need reflected in a 2016 CFA Institute survey where a majority of investors indicated they expect standard setters to define key subtotals like operating profit for consistency.

A heavily indebted business might show low net profits, but its core operations could be highly profitable.

Example: You're comparing two businesses to buy:

• Company A: $100,000 net profit
• Company B: $80,000 net profit, but pays $40,000 in annual interest

Using NOPAT, Company B's operational profit is actually $120,000, higher than Company A. This reveals Company B's true potential if you restructure its debt.

Improved decision-making

NOPAT feeds directly into Economic Value Added (EVA), a metric that shows whether a business creates value beyond its cost of capital.

For this purpose, NOPAT may be adjusted. For example, some financial models suggest that R&D and promotion costs should be capitalised instead of expensed.

EVA formula: NOPAT - (Total invested capital × Cost of capital)

Example calculation:

• NOPAT: $50,000
• Total invested capital: $200,000 (loans + equity)
• Weighted average cost of capital: 3%
• EVA: $50,000 - ($200,000 × 3%) = $44,000

This $44,000 represents the value created above what investors require as a return. This makes EVA essential for evaluating investment performance.

For more details, see these EVA calculation examples.

NOPAT formula explained

The standard NOPAT formula is:

NOPAT = Operating profit × (1 - Tax rate)

Here's what each component means:

• Operating profit: earnings from core business activities before interest and taxes
• Tax rate: your effective corporate tax rate (total taxes paid ÷ operating profit)
• (1 - Tax rate): the portion of profit you keep after taxes

Quick example: With $100,000 operating profit and a 25% tax rate:

NOPAT = $100,000 × (1 - 0.25) = $75,000

How to Calculate NOPAT

To understand the formula, let's see how it relates to a net operating profit after tax example.

1. Determine operating profit

Start by calculating your operating profit using this formula:

Operating profit = Gross profit - Operating expenses

Where gross profit = Revenue - Cost of goods sold

Make sure to exclude any non-operating income like investment returns or rental income from other properties.

2. Find the tax rate

Calculate your effective tax rate:

Effective tax rate = Income tax paid ÷ Operating profit

Example: $20,000 tax on $100,000 operating profit = 20% effective rate

If you expect significantly higher earnings, check whether you'll move into a higher tax bracket and adjust your rate accordingly.

3. Apply the formula

Apply the formula with your numbers.

Use these values for the calculation:

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

Calculation:

NOPAT = $50,000 × (1 - 0.25) = $50,000 × 0.75 = $37,500

What this tells you: Your core business operations generate $37,500 in profit after taxes, regardless of how the business is financed.

NOPAT calculation example

Here's a complete example showing how to calculate NOPAT for a small retail business.

Start with this financial data from the business:

• Revenue: $500,000
• Cost of goods sold: $200,000
• Operating expenses: $150,000
• Interest expense: $10,000
• Rental income (from subletting storage): $5,000
• Income tax paid: $28,000

Step 1: Calculate gross profit

$500,000 - $200,000 = $300,000

Step 2: Calculate operating profit

$300,000 - $150,000 = $150,000

(Exclude the $5,000 rental income since it's non-operating)

Step 3: Determine effective tax rate

$28,000 ÷ $150,000 = 18.7%

Step 4: Apply the NOPAT formula

$150,000 × (1 - 0.187) = $150,000 × 0.813 = $121,950

What this means

The retail business generates $121,950 in operational profit after taxes. This figure excludes the $10,000 interest expense and $5,000 rental income, giving you a clear view of core business performance.

NOPAT vs net income

Net income reflects total profitability after all expenses, while NOPAT shows only operational profitability before financing costs.

Both NOPAT and net income include:

• Taxes
• Depreciation/amortisation

While only net income includes:

• Interest expenses
• Non-operating income

Use NOPAT to evaluate operational efficiency. Use net income when you need to see total profitability.

Bakery example:

• Net income: $100,000
• Minus rental income (non-operating): $12,000
• Plus interest expense (excluded from NOPAT): $8,000
• NOPAT: $96,000

The calculation adds back interest because NOPAT excludes it, and subtracts non-operating income.

If a business has no debt and no non-operating income, NOPAT and net income will be identical.

Operating profit vs NOPAT

Operating profit is NOPAT before taxes. Both metrics exclude interest and non-operating items, but operating profit shows earnings before the tax bill, while NOPAT shows what remains after taxes.

The relationship between these metrics is:

• Operating profit × (1 - tax rate) = NOPAT
• NOPAT ÷ (1 - tax rate) = Operating profit

Example: If NOPAT is $80,000 and the tax rate is 20%, operating profit is $100,000.

NOPAT vs EBIT

NOPAT and EBIT are related but not identical. EBIT (Earnings Before Interest and Tax) shows profit before both interest and taxes, while NOPAT shows profit after taxes but before interest.

A 2016 CFA Institute survey found that 45.9% of investors use EBIT in their analysis, making it a common point of comparison.

NOPAT:

• deducts taxes
• excludes interest
• typically excludes non-operating income

While EBIT:

• does not deduct taxes
• also excludes interest
• often includes non-operating income

The relationship between these metrics is:

NOPAT = EBIT × (1 - Tax rate)

Choose the right metric for your analysis:

• Use EBIT when comparing companies across different tax jurisdictions or when taxes aren't relevant to your analysis.
• Use NOPAT when you need a realistic after-tax view of operational profitability or when calculating EVA.

Example: A business has EBIT of $100,000 and a 25% tax rate.

NOPAT = $100,000 × (1 - 0.25) = $75,000

NOPAT vs EBITDA

EBITDA (Earnings Before Interest, Taxes, Depreciation, and Amortisation) measures cash-generating ability. It's a popular metric: a CFA Institute survey found that 69.8% of investors use it in their analysis. In contrast, NOPAT measures operational profitability after taxes.

Here are the key differences between NOPAT and EBITDA:

NOPAT:

• Depreciation/amortisation: Included (deducted)
• Taxes: Included (deducted)
• Best for: Profitability analysis, EVA

EBITDA:

• Depreciation/amortisation: Excluded (added back)
• Taxes: Excluded
• Best for: Cash flow analysis, debt capacity

Choose the right metric for your analysis:

• Use NOPAT when evaluating true operational profitability or investment returns.
• Use EBITDA when assessing a company's ability to service debt or generate cash.

EBITDA is often higher than NOPAT because it excludes depreciation, amortisation, and taxes.

FAQs on NOPAT

These questions cover NOPAT basics and how it compares to other financial metrics.

Is NOPAT the same as EBIT?

No. EBIT (Earnings Before Interest and Tax) is earnings before interest and tax, while NOPAT is earnings after tax but before interest. The relationship is: NOPAT = EBIT × (1 - Tax rate).

Is NOPAT the same as free cash flow?

No. NOPAT measures operational profit, which includes non-cash expenses, while free cash flow measures actual cash available after capital expenditures.

To bridge this gap in some analyses, adjustments are needed. For example, when calculating NOPAT for EVA, accounting depreciation is often added back and replaced with a charge for economic depreciation.

A business can have positive NOPAT but negative free cash flow if it's investing heavily in growth.

How is NOPAT different from EBITDA?

NOPAT includes depreciation, amortisation, and taxes in its calculation, while EBITDA excludes all three. NOPAT shows profitability; EBITDA shows cash-generating potential.

When should I use NOPAT instead of net income?

Use NOPAT when comparing businesses with different debt levels or when calculating return on invested capital. Net income is better for understanding total profitability including financing costs.

Can NOPAT be negative?

Yes. If a business has operating losses that exceed any tax benefits, NOPAT will be negative. This indicates the core operations aren't generating profit, regardless of how the business is financed.
