R&D intensity

Research and development expense as a share of revenue — how much of each sales dollar the company reinvests in building what it will sell next. It is expensed as incurred under GAAP, so a heavy research year depresses today's operating margin to fund products that arrive in later ones.

Formula
R&D intensity = R&D expense ÷ Revenue
Drivers — what actually moves it
Product cycle
spend concentrates ahead of platform transitions and new architectures.
Competitive clock
in winner-take-most markets, underspending rivals is the more expensive mistake.
Revenue scale
the same absolute program shrinks as a ratio when the top line grows — operating leverage inside R&D.

Sector caveats — where this breaks
  • GAAP expenses R&D immediately while capitalizing factories — asset-light research businesses look less invested than they are.
  • A falling ratio can mean discipline or harvest — direction alone does not say which.

Educational use only — not investment advice. Figures come from public SEC filings; Echelon teaches you to analyze data, it never recommends buying or selling any security.
