# Pre-Compliance Testing: Spend $2K Before You Spend $15K

The average formal EMC test session costs $8,000 to $20,000. Pre-compliance
testing costs $1,000 to $3,000. Most hardware teams skip it to save time.
They consistently spend more time and money as a result.

### The cost comparison

A formal EMC test session costs between eight and twenty thousand dollars. Pre-compliance testing costs one to three thousand. Most teams skip it to save time. They consistently spend more time and more money as a result.

### What pre-compliance catches

Pre-compliance testing catches what would fail formally: emission spikes from clocks, common-mode noise pushing conducted emissions out of limit, ground plane issues that only show with the enclosure fitted. Fixable before your board locks — after, it's a costly respin.

### The ROI

A formal test failure means rebooking the lab, four to eight weeks out, plus fees and engineering time under pressure. Two thousand spent on pre-compliance early routinely saves twenty thousand in rework and delay.
