What is the Percent Yield Calculator?

Calculate percent yield from actual and theoretical yield. ITS Research Solution keeps the interactive tool above the explanation so you can calculate first and then review the method used.

Formula or method

% yield = actual yield / theoretical yield × 100%.

How to use this tool

Enter the requested values using consistent units, run the calculation and review the main result plus any supporting values. An actual yield of 8.5 g from a theoretical 10 g is 85%.

Interpretation and limitations

Values above 100% can indicate impurities, retained solvent, measurement error or an incorrect theoretical basis. Always check source data, units, rounding and discipline-specific requirements before using a result in assessed, published, regulated or high-stakes work.
