This calculator does not take into account unexpected angles or additional corners due to the presence of a cabinet, for example. Such particularities may increase the quantities required.
To estimate wastage, the calculator uses the following amounts: 10% for crowns and 5% for all other types of moulding. However, with crowns over 5 inches wide, anticipate a minimum loss of 10 inches on each corner.
Avoid making joints on casings unless absolutely necessary. The higher quality finish will more than make up for any resulting wastage. Keep scraps for cabinet interiors.
