# Percent Yield Calculator

This free online percent yield calculator calculates the percent yield by using the values of actual yield and theoretical yield.

**Percent yield** is actually a ratio that allows you to calculate the effectiveness of a chemical reaction. It is calculated as the **actual yield divided by the theoretical yield and multiplied by 100**. If we have a condition that actual and theoretical yield is the same then we have the percent yield is 100%. This is somehow impossible as we get the side products in a reaction and some of the reactants are wasted during the reaction.

## Formula of Percent Yield Calculator

The formula to calculate the percent yield is as follows

Percent yield = (actual yield / theoretical yield) x 100

**Where,**

Actual yield = amount of product that is obtained by a chemical reaction.

Theoretical yield = obtained from the stoichiometric or balanced equation.

**Note:**

### Example

If we have the amount of actual yield as 5g, and the amount of theoretical yield as 7g. Then find the percent yield.

**Given data**

actual yield = 5 g

theoretical yield = 7 g

**To Find**

percent yield = ?

**Solution**

By using the formula listed below, you can find the percent yield.

Percent yield = (actual yield / theoretical yield) x 100

Putting values in the formula:

percent yield = ( 5 / 7) * 100

percent yield = 71.43%
