NAGS Pricing Fails to Reflect Material Cost Reality, Leaving Shops to Bridge the Gap

By the final week of March 2022, the disconnect between National Auto Glass Specifications (NAGS) benchmark pricing and real-world glass material costs had become a defining operational challenge for independent shops.

The NAGS pricing system, which most insurance direct-repair programs use as the basis for reimbursement calculations, had not adjusted quickly enough to reflect the dramatic material cost escalation of 2021 and early 2022. Shops that had agreed to reimbursement formulas tied to NAGS list prices found themselves in the position of absorbing the gap between what insurers paid and what distributors charged.

Jaymie Percival of Superior Auto Glass in Texas and Matt Bailey of 20/20 Auto Glass in South Carolina described the squeeze. Bailey said ordering OEM glass—which he did specifically to avoid calibration compatibility issues—sometimes meant waiting months due to backorders, and dealerships typically charged restocking fees of 25–30% if a customer cancelled during the wait.

The pricing environment pushed some shops toward two strategies: raising retail prices for customers who paid out-of-pocket and selectively declining insurance assignments that did not cover material costs. Both approaches carried trade-offs—higher retail prices could drive customers to national chains, and declining insurance work could damage insurer relationships that generated referral volume.

State-level legislative advocacy around glass billing transparency had been ongoing for years in states like Florida and Texas, but 2022's cost environment gave that advocacy fresh urgency. Shops that tracked and documented their actual material costs per job—comparing them to insurance reimbursements—were in a stronger position to participate in industry association lobbying efforts addressing the NAGS-pricing gap.

A subset of independent shops in 2022 had begun to experiment with a different response to the NAGS pricing problem: direct consumer communication about the gap. By educating customers on the difference between what their insurer was willing to pay and what a quality installation actually cost, some shops were successfully collecting the difference as a consumer-pay supplement. While regulatorily sensitive in some states, the practice was legal in most jurisdictions and gave shops a path to cost recovery without requiring insurer renegotiation.
