Frequently Asked Questions

This tool helps you combine multiple impairment percentages using the method described on page 604 of the AMA Guides, 5th Edition. It also provides UE → WPI and LE → WPI conversions, saving you time and avoiding manual errors.
  • Enter two or more impairment percentages.
  • Click "Calculate."
  • See the final Combined Value and conversions.
You can add up to 12 values at a time.
These refer to standardized formulas:
• UE to WPI = Upper Extremity × 0.60
• LE to WPI = Lower Extremity × 0.40

These factors follow AMA 5th Edition guidelines.
We follow the AMA Guides 5th Edition Combined Values Chart: impairments are combined largest-first, and each pairwise step is rounded to the nearest whole percent. This matches the printed chart exactly and makes the result independent of the order you enter values.
