Module 1.6: Engineering Budget & Capex/Opex
The financial architecture of engineering organizations: budget anatomy, Capex vs Opex classification, software capitalization, and R&D tax credit optimization.
🎯 What You'll Learn
- ✓ The four categories of engineering budget (including hidden costs)
- ✓ How Capex vs Opex classification impacts EBITDA and valuations
- ✓ How to maximize R&D tax credit claims (most companies under-claim 30-50%)
Lesson 1: Engineering Budget Anatomy
The engineering budget has four major categories: People (65-80%), Infrastructure (10-20%), Tools/Licenses (5-10%), and Other (3-5%). Understanding what you're actually spending on is the foundation of engineering economics.
Salary + benefits + taxes + equipment + office space + recruiter fees = "burdened" cost. A $180K salary engineer actually costs $230K-$270K fully burdened.
Cloud hosting, CDN, databases, monitoring, CI/CD, staging environments. The fastest-growing budget category as companies scale.
GitHub, Jira, Figma, Datadog, PagerDuty, SonarQube, and the 40+ other tools in a typical engineering org. "Shadow SaaS" (tools purchased on team credit cards) is usually 20-30% more.
Recruiting costs (3-6 months per hire), onboarding productivity loss, context-switching overhead, and meeting costs. These are real expenses that rarely appear in "engineering budget" conversations.
Calculate your engineering budget breakdown by category. Include burdened people costs, infrastructure, tools (including shadow SaaS), and hidden costs.
Lesson 2: Capex vs Opex Classification
Whether engineering work is classified as Capital Expenditure (Capex) or Operating Expenditure (Opex) has major financial implications: Capex is amortized over years and improves EBITDA; Opex hits the P&L immediately.
New feature development (post-feasibility), new platform/product builds, major enhancements with measurable useful life. Must meet ASC 350-40 criteria for internal-use software.
Bug fixes, maintenance, planning/research, training, general administration, support. All non-capitalizable engineering work.
Capitalizing $5M of engineering work spreads the expense over 3-5 years instead of hitting this quarter. This can improve EBITDA by $4-4.5M in the current year.
Categorize your last quarter's engineering work: what percentage is capitalizable (new features, new platforms) vs. expensed (maintenance, bugs, support)?
Lesson 3: R&D Tax Credits
The R&D Tax Credit (IRC Section 41) allows companies to claim 10-20% of qualifying R&D expenses as tax credits. Most software companies under-claim by 30-50% because they don't know what qualifies.
Developing new technology, improving performance of existing software, integrating systems in novel ways, developing proprietary algorithms. The four-part test: technological uncertainty, process of experimentation, technical in nature, permitted purpose.
Engineer salaries (proportional to qualifying time), contractor costs (65%), and supplies used in R&D. Cloud infrastructure used for development (not production) may also qualify.
Federal: ~6.5% of QRE (simplified calculation). Many states add 3-12% on top. A $10M engineering budget with 60% QRE = $6M × 6.5% = $390K federal credit + state credits.
Estimate your company's R&D tax credit opportunity: (qualifying engineer salaries) × (% time on qualifying activities) × 6.5% federal rate.
