NRE Costs Explained: The Foundational Game Changer in Product Design

Key Takeaways: What You will Learn About NRE in Manufacturing

• ► What NRE includes: From first sketch to first article — design, prototyping, testing, and certification all happen before production starts.
• ► Why NRE matters: It shapes product quality, time-to-market, and long-term cost efficiency.
• ► NRE vs. recurring costs: Know the difference between upfront investment and per-unit production expenses.
• ► When to accept or negotiate NRE: Understand when NRE is essential and when recurring-only pricing is a better fit.
• ► How to reduce NRE risk: Use modular design, agile prototyping, and supplier collaboration to lower risk and cost.

In product development, it is easy to get caught up in the usual suspects — materials, labor, logistics. But before the first unit is built, there is a critical investment that often determines a product’s success or failure: Non-Recurring Costs (NRE).

This blog breaks down what NRE involves, why it is strategically important, and how to manage it effectively — drawing from industry practice, academic research, and real-world case studies.

What Is NRE (Non-Recurring Engineering)?

NRE refers to the one-time engineering costs incurred before the first article of a product or system is built. It is the technical groundwork — the design, testing, and validation — that turns a concept into a manufacturing-ready product.

Common NRE activities include:

• Product or system architecture and design
• Prototype development and validation
• Software and firmware design and engineering
• Manufacturing process documentation and training
• Regulatory and compliance certification

What is Included in NRE Costs?

NRE spans multiple engineering and operational domains. Think of it as a multi-disciplinary investment:

• Engineering & Design: CAD modeling, simulations, design reviews
• Prototyping: Developing hardware and software simulations, prototypes and/or mock-ups
• Tooling: Custom molds, dies, jigs, and fixtures
• Software: Embedded systems, UI, connectivity, documentation at system, manufacturing, support, and end-user levels
• Test System Development: Automated test equipment (ATE), test scripts, diagnostics
• Certifications: CE, UL, FCC, FDA, and other regulatory approvals

NRE vs Recurring Costs: What is the Difference?

Example: In a robotic arm project, NRE includes developing the control algorithms and mechanical design. Recurring costs? Motors, metal parts, and assembly labor.

Why NRE Matters in Product Development

NRE is an investment and commitment to your product. It is the groundwork that when done right can:

• Accelerate product launch timelines through effective design and validation
• Improve quality and meet regulatory compliance
• Develop advanced and/or customized features
• Lower long-term costs through design for manufacturability (DFM) and testability (DFT)

Technical and Financial Implications of NRE

How NRE Impacts Product Lifecycle Cost

Investing in NRE upfront can save you from frequent redesigns, recalls, and production delays. Modular designs for products and systems may cost more initially but simplify future refitting or updates for new product and system variants.

NRE and Scalability: Reusability vs One-off

Reusable design elements — like shared modules or test platforms — will share NRE across multiple products. One-off designs offer the same benefits but do not offer the opportunity to combine expenses.

ROI: When and How NRE Pays Off 

When you are designing a new product, NRE is a key investment. It helps you shape your unique product to represent your brand and position your company as an innovator. The investment is especially worthwhile when:

• Sales volume is high — spreading costs over many units
• The product lasts long — more time to recoup investment
• Parts of the design are reusable — boosting future efficiency
• You face regulation or strong competition —requiring tailored solutions

An important strategic decision in this context is whether to handle NRE internally or outsource it. This choice depends on your company’s technical expertise, available resources, and time-to-market goals. Internal development offers greater control and alignment with your long-term vision, while outsourcing can provide access to specialized skills, reduce risk, and accelerate development — especially when in-house capabilities are limited.

Common Mistakes in Scoping NRE

• Underestimating the complexity of the project<
• Skipping the test design process
• Not planning ahead for certification
• Ignoring or mislabeling design revisions.

When Should You Accept or Negotiate NRE?

✅ Accept NRE costs when:

• You are building something new
• Certification is required
• You are integrating with legacy systems
• You are looking to simplify production down the line

❌ When to Push for Recurring-Only Pricing

Recurring-only pricing isn’t an option when building a custom product. NRE is always required to develop a tailored solution. The only strategic choice is whether to manage it in-house or outsource it — depending on your team’s capabilities and timeline.

How to Lower Recurring Costs Without Sacrificing Quality?

Once NRE is done, recurring costs become the focus. Here are some tips to reduce recurring costs:

How Averna Helps Minimize your NRE Risk

Averna supports companies in managing NRE through:

• Modular test system designs
• Proven design libraries and reusable test frameworks
• Agile prototyping
• Transparent scoping
• Clear project strategy

Before the first unit is built, Non-Recurring Engineering (NRE) lays the groundwork for quality, compliance, and scalability. It’s not optional—it’s essential. The only real decision is how to handle it: in-house for control and alignment, or outsourced for speed and expertise. Managing NRE wisely means launching smarter, faster, and more competitively .
