# 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%
