percent yield of fischer esterification

Why is 100% yield not obtained when forming an ester?
The reaction in which ester is obtained from alcohol (ROH) and carboxylic acid (RCOOH) remains in the equilibrium state.
The produced products, ( H 2 O , R C O O R ) get converted back in reactants (ROH, RCOOH).
Therefore, the yield of ester remains relatively low.
Fischer Esterification is an organic reaction which is employed to convert carboxylic acids in the presence of excess alcohol and a strong acid catalyst to give an ester as the final product.
This ester is formed along with water.
