Insight & Summary of TSMC’s Operating Expenses Breakdown Analysis

TSMC’s operating expenses have grown roughly fourfold over 2015–2025, but the composition of that growth reveals a company increasingly investing in administrative capacity relative to R&D, even as R&D remains the overwhelming majority of total spend.

• OpEx Numbers: Sustained Growth, With a Sharp Step-Up After 2020 Total operating expenses grew from NT$88,467 million (2015) to NT$345,649 million (2025) — a 291% increase. Growth accelerated markedly from 2020 onward: after a relatively modest 3.9%–11.3% annual pace through 2018, growth jumped to 21.4% (2020), 16.7% (2021), and a striking 34.0% (2022) — the fastest single-year OpEx growth in the dataset — before moderating somewhat to 12.0%–18.6% in 2023–2025. This acceleration lines up closely with TSMC’s well-documented capacity expansion and R&D investment cycle over the same period.

• OpEx Mix: R&D Dominant but Slowly Ceding Share to G&A R&D consistently represents the large majority of TSMC’s operating expenses, though its share has drifted down from 76.6% (2018, the peak) to 71.3% (2025). General and Administrative expense has moved in the opposite direction, rising from 18.1% (2018) to a peak of 27.8% (2024) before easing to 23.8% in 2025 — the most volatile mix component in the dataset. Marketing has remained consistently small throughout, never exceeding 6.4% of total OpEx, suggesting TSMC’s B2B foundry model requires comparatively little marketing spend relative to R&D-intensive or administratively complex operations.

• OpEx Growth: G&A the Most Volatile Line Item G&A growth has been considerably more erratic than R&D growth — swinging from -4.4% (2018) to 44.9% (2022) to 37.6% (2024) to -1.7% (2025), a pattern of sharp reversals rather than steady trend. R&D growth, by contrast, has been more consistently positive throughout, ranging from 6.4% to 30.9% with no negative years in the entire dataset — reflecting R&D’s role as a more strategically protected, less discretionary spending category for TSMC than G&A.

• Revenue, Margin, and the OpEx Efficiency Ratio: Margin Expansion Despite Rising Absolute Spend Despite operating expenses growing substantially in absolute terms, % of OpEx to Net Revenue has actually trended down over the long run — from 10.5% (2015) to 9.1% (2025), with the lowest point in the entire dataset reached in the most recent year. This is the clearest sign of operating leverage in the dataset: OpEx is growing, but net revenue is growing faster, allowing TSMC to spend more on R&D and G&A in absolute terms while consuming a shrinking share of revenue to do so. Operating margin reflects this directly, expanding from 37.9% (2015) to 50.8% (2025) — an all-time high in this dataset, achieved even as 2025’s net revenue growth (31.6%) outpaced total OpEx growth (14.8%) by a wide margin that same year.

• Cross-Metric Comparison Reading OpEx growth against net revenue growth side by side sharpens the operating-leverage story: in 2023, net revenue actually declined (-4.5%) while total OpEx still grew 12.0% — the one year in the dataset where spending discipline lagged revenue, and correspondingly the year with the highest % of OpEx to Net Revenue (11.7%). Every other year with strong revenue growth (2020, 2022, 2024, 2025) saw the opposite pattern: revenue growth outpacing or roughly matching OpEx growth, keeping the efficiency ratio in check.

• Structural Takeaway: TSMC’s operating expense structure remains R&D-anchored, but G&A has grown meaningfully as a share of the mix and remains the least predictable line item to forecast given its volatility. The company’s operating leverage has strengthened over the decade — OpEx as a share of revenue has fallen even as absolute spending has risen sharply — culminating in 2025’s record 50.8% operating margin. The 2023 divergence (revenue down, OpEx still up) is the one cautionary data point in an otherwise consistent efficiency-improvement trend, and it’s worth monitoring whether a similar revenue slowdown in the future would again outpace TSMC’s ability to moderate spending growth in the short term.
