Non-Recurring Engineering (NRE) costs cover everything required to go from concept to production-ready: design engineering, prototype fabrication, tooling and fixture design, programming, first-article inspection, and process validation. These costs are incurred once and must be recovered through the production pricing or charged upfront.
How NRE is handled in quoting has significant business implications. Some manufacturers charge NRE separately as a line item. Others amortize it across an expected production volume. The choice affects both the quoted unit price and the financial risk if production volumes fall short of projections.
Tracking actual NRE spend against estimates is critical for improving future quoting accuracy. Many shops significantly underestimate NRE, particularly for complex tooling and first-article qualification, which erodes margins on new programs.
