Percent Yield Calculator
Calculate reaction percent yield, recovered shortfall, and excess above theoretical yield from actual and theoretical product amounts.
Formula
Percent yield = actual yield / theoretical yield x 100%.
About the Percent Yield Calculator
Calculate reaction percent yield, recovered shortfall, and excess above theoretical yield from actual and theoretical product amounts.
How the Percent Yield Calculator Works
Actual product amount is divided by the nonzero theoretical amount in the same unit, while their difference reports loss or apparent excess.
Formula
Percent yield = actual yield / theoretical yield x 100%.
The calculation runs in your browser. Values are validated for required ranges, compatible units, and method-specific restrictions before results are displayed.

Accuracy and Limitations
Actual and theoretical yields must describe the same product and use the same unit. Values above 100% can indicate impurities, solvent, side products, or measurement error.
Keep units consistent, use measurements that represent the actual situation, retain full precision during the calculation, and round only the final answer. Professional decisions may require current official rules, field measurements, laboratory methods, or specialist review.
Frequently Asked Questions
What does the Percent Yield Calculator calculate?
