I build custom cabinetry for a living, I don't do economical cabinets only upper quality to high end. When I am bidding on a job I start with a basic formula. This is $15.50 per lineal inch of cabinet, uppers and lowers. Then I add in components, doors, drawers, usually a hundred bucks each. The doors a raised panel style and the drawers are dovetailed on four corners, the cabinets are faceframe construction and the doors are inset, the customer is reuired to supply the hardware unless they want the $2.00 hinges and the $1.25 knobs. The price includes priming and installation. If a stain grade finish is required I figure it out by time and materials and add that to the total.
Here is an example;
a 42" lower cabinet with a pair of doors, a false drawer front and three drawers.
42 x $15.50 = $651.00 for the box (faceframe construction, fancy toekick)
2 doors = $200.00
3 drawers = $300.00
False front = $35.00
--------------------
Total $1,186.00
Add about $300.00 for a stain grade finish (on maple, higher for cherry and mahogany)
It may sound high

but it ends up being about 2-3 days of work to build and install. I live in CT.
