It depends on the graphics you are printing. If your design is red, yellow and purple, and you need them to match a certain color in a logo, then you would go with spot colors. If you are printing a picture, then you have to go with CMYK. If you are printing a photo and a logo that needs to be a certain PMS color, then it would be CMYK plus a spot.
You can usually get away with printing CMYK to cover all the colors, but if you have small type that is, say, green, then you might want to put that on a spot plate so the type is sharp and doesn't look blurry, which it may if printed process (CMYK)
And yes, each time you add a color, the cost will go up.
Hope this helps
