The important thing is to make certain that your prices are current - many folks are a year or two behind in their prices. Also make sure that you know the going rate for weddings cake whatever they are covered or filled with. If you are comparing the prices of your homemade and elaborately decorated cakes with places like Sam's and Costco, you are likely undercharging substantially. These stores undercut the prices charged by better bakeries.
If your cakes are from scratch or made to include items like butter, sour cream, cream, whole milk, then they are worth much more than a cake mix made per the box instructions. If you use milk, cream, butter and such in your icings, then that icing is more expensive to produce than all shortening and water icing. If you fill your cakes with anything other than standard buttercream, the filling is more expensive. If you make fondant or gumpaste decorations or elaborate Royal Icing decorations, add fondant pearls and such, then these cakes are more expensive. If you transport the cake and do the set-up and the table set-up, there is also a fee charged for this. If you arrange fresh or silk flowers, there is a fee for this.
