Percent Yield Interpretation Scale

Percent Yield	Laboratory Assessment	Action Required
> 100%	Error: Product is wet or impure	Dry product, check for solvent or salt contamination
90% - 100%	Exceptional recovery	Ideal synthetic efficiency
70% - 89%	Good laboratory yield	Standard for organic syntheses
50% - 69%	Moderate yield	Inspect side reactions or extraction efficiency
< 50%	Low yield	Optimize temperature, catalyst, or reaction time

How to Use the Percent Yield Calculator

1 Enter the actual measured mass of product recovered.
2 Enter the theoretical maximum yield calculated from stoichiometry.
3 Obtain reaction percent yield.
