Costco Wholesale Corp. (NASDAQ:COST)

The analysis of economic performance from August 2020 to August 2025 reveals a general upward trajectory in value creation, characterized by growth in operating profits despite a rising cost of capital and fluctuations in invested capital.

Net Operating Profit After Taxes (NOPAT)

A consistent growth trend is observed in NOPAT, rising from 4,254 million US$ in 2020 to 7,834 million US$ by 2025. A temporary contraction occurred in September 2023, where NOPAT declined to 5,694 million US$ from the previous year's 6,421 million US$. However, this was followed by a strong recovery, with the figure reaching its peak in the final reporting period.

Cost of Capital and Invested Capital

The cost of capital exhibited a steady incremental increase over the period, moving from 14.29% in 2020 to a plateau of 14.87% in 2024 and 2025. Concurrently, invested capital demonstrated a general expansion, increasing from 29,043 million US$ in 2020 to 37,996 million US$ in 2025. Notable fluctuations were present, specifically a decrease in invested capital in 2021 and 2024, indicating periods of capital optimization or divestment.

Economic Profit and Value Creation

Economic profit remained positive throughout the analyzed timeframe, signifying that the entity consistently generated returns exceeding its cost of capital. A significant surge in value creation occurred between 2020 and 2022, with economic profit rising from 105 million US$ to 1,812 million US$. A sharp decline was recorded in 2023, dropping to 572 million US$, which correlates with the simultaneous dip in NOPAT and an increase in invested capital. A robust recovery followed in 2024 and 2025, with economic profit peaking at 2,183 million US$, suggesting enhanced operational efficiency and successful scaling of the capital base.

Overall, the data indicates that the increase in the cost of capital was offset by substantial growth in NOPAT, resulting in a net increase in economic profit over the long term. The volatility observed in 2023 represents a temporary deviation from an otherwise positive trend in economic value added.

Net Income Attributable to Costco

The net income showed a consistent upward trend over the six-year period. Starting at 4,002 million USD, it increased steadily each year, reaching 8,099 million USD in the latest period. The largest year-over-year growth appeared from the 2023 to 2024 period, with an increase of approximately 1,075 million USD. Overall, net income approximately doubled from the first to the last reported year, reflecting strong profitability growth.

Net Operating Profit After Taxes (NOPAT)

NOPAT followed a generally increasing pattern as well, starting at 4,254 million USD in the earliest period and rising to 7,834 million USD in the most recent year. There was a slight deviation from the upward trend between 2022 and 2023, where NOPAT decreased from 6,421 million USD to 5,694 million USD before resuming growth. The recovery that followed saw a notable increase to 7,032 million USD and then to 7,834 million USD. This suggests a temporary operational challenge was overcome, leading to renewed profitability improvements.

General Observations

Both net income and NOPAT exhibited significant growth over the examined period, reinforcing a positive operational and financial trajectory. The temporary dip in NOPAT suggests some operational or cost-related challenges in the 2023 fiscal year, yet the strong rebound indicates effective management response or favorable market conditions. The steadier growth in net income compared to the fluctuating pattern of NOPAT could suggest impacts of non-operating factors or variations in tax effects during the period.

The financial data indicates a consistent upward trend in both the provision for income taxes and cash operating taxes over the analyzed period. This upward trajectory suggests increasing profitability or taxable income, requiring higher tax allocations.

Provision for Income Taxes

The provision for income taxes has increased from $1,308 million in 2020 to $2,719 million in 2025. This steady growth reflects a compounded annual increase, highlighting the company's growing tax liability over the years. The year-over-year increases range between approximately 17% to 24%, showing sustained expansion without volatility.

Cash Operating Taxes

Cash operating taxes also show a consistent rise from $1,246 million in 2020 to $2,750 million in 2025. Notably, cash operating taxes slightly exceed the provision for income taxes, which could indicate timing differences or tax payment strategies. The year-over-year growth in cash operational taxes aligns closely with the provision, reinforcing the narrative of increased cash outflows related to tax expenses.

Overall, the data reveals a parallel and proportionate increase in tax provisioning and payments, reflecting robust business performance and likely higher earnings. The absence of any decline or irregularity in these amounts suggests stable tax management and continuous financial growth throughout the period under review.

Total reported debt & leases

The total reported debt and leases exhibit a generally declining trend over the observed periods. Starting from approximately $11.1 billion, the amount slightly increased to around $11.4 billion in the second year, then consistently decreased in the subsequent years, reaching approximately $9.9 billion in the latest period. This suggests a gradual reduction in leverage or obligations related to debt and leases over time.

Total Costco stockholders’ equity

Stockholders' equity demonstrates significant growth across the years. There is an initial slight decline from about $18.3 billion to $17.6 billion, followed by a substantial increase to over $20.6 billion in the third period. This upward trajectory continues more markedly in the following years, reaching nearly $29.2 billion in the most recent period. The growth in equity indicates strengthening financial stability and retained earnings accumulation.

Invested capital

Invested capital shows a consistent upward trend, rising from approximately $29.0 billion at the beginning of the period to nearly $38.0 billion in the latest year. Despite a slight dip in one of the middle years, the general movement is positive, suggesting ongoing investment in the company's operations and assets. This increase in invested capital aligns with the growth observed in stockholders’ equity, reflecting expansion and reinvestment activities.

The financial performance over the observed six-year period indicates a general upward trajectory in economic value creation, characterized by significant growth in economic profit and a fluctuating but overall increasing economic spread ratio.

Economic Profit Trends

Economic profit exhibited substantial growth, rising from 105 million USD in 2020 to 2,183 million USD by 2025. A notable period of acceleration occurred between 2020 and 2022, followed by a sharp contraction in 2023, where profit fell to 572 million USD. However, a strong recovery was realized in 2024 and 2025, with values stabilizing above 2,100 million USD.

Invested Capital Dynamics

Invested capital demonstrated a steady long-term increase, growing from 29,043 million USD in 2020 to 37,996 million USD in 2025. While there was a slight reduction in capital in 2021 and 2024, the overall trend reflects an expansion of the capital base to support operations.

Economic Spread Ratio Analysis

The economic spread ratio, representing the efficiency of value creation over the cost of capital, showed significant volatility. Starting at a marginal 0.36% in 2020, the ratio peaked at 6.44% in 2024. The decline observed in 2023 to 1.64% corresponds with the simultaneous drop in economic profit and an increase in invested capital, indicating a temporary reduction in capital efficiency. The ratio concluded the period at 5.75% in 2025, maintaining a level substantially higher than the 2020 baseline.

The correlation between these metrics suggests that while the capital base has expanded, the growth in economic profit has largely outpaced the cost of that capital, resulting in a strengthened capacity to generate economic value by the end of the period.

The financial performance from August 2020 to August 2025 is characterized by consistent revenue expansion alongside fluctuations in the generation of economic value.

Net Sales Trajectory

A sustained upward trend in net sales is observed, increasing from US$ 163,220 million in 2020 to US$ 269,912 million by 2025. This growth indicates a steady expansion of the company's top-line scale throughout the analyzed period.

Economic Profit Volatility

Economic profit exhibited significant variance. A substantial increase occurred between 2020 and 2022, with profit rising from US$ 105 million to US$ 1,812 million. This was followed by a sharp contraction in 2023 to US$ 572 million, before recovering strongly to reach US$ 2,126 million in 2024 and US$ 2,183 million in 2025.

Economic Profit Margin Analysis

The economic profit margin mirrors the volatility of the absolute economic profit. The margin improved from 0.06% in 2020 to 0.81% in 2022, before declining to 0.24% in 2023. A recovery is noted in 2024 with a peak margin of 0.85%, which slightly normalized to 0.81% in 2025. The maintenance of a positive economic profit margin across all periods indicates that the company consistently generated returns in excess of its cost of capital.
