Theoretical Yield Calculator — free online calculator.
Formula
- Calculate theoretical product mass from limiting-reagent moles, stoichiometric coefficients, and product molar mass.
- Use the units, labels and assumptions shown beside each input so the formula is applied consistently.
- Changing any input above recalculates the result with the same calculation engine used by this page.
Example: Theoretical Yield
The calculation uses the balanced-reaction mole ratio to convert limiting-reagent moles to product moles, then multiplies by product molar mass.

Frequently asked questions
What does the Theoretical Yield calculate?
If 1 mol of limiting reagent produces product in a 1:1 ratio and the product molar mass is 100 g/mol, the theoretical yield is 100 g.
Which values should I enter?
Enter the values requested by the calculator using the labels and units shown on the page.
What formula does this calculator use?
The calculator uses the following relationship: Theoretical yield (g) = Reactant moles × (Product coefficient / Reactant coefficient) × Product molar mass (g/mol).
Why might my result differ from another source?
Results can differ when another source uses different units, rounding rules, conventions or assumptions. Compare the inputs and definitions before comparing results.
Does the result update automatically?
Yes. Changing an input updates the result using the same calculation engine shown on this page.
