We charge $7 a minute with a $50 minimum charge. Very often, discussing your project will take longer than actually running the piece through the planer. Slabs can cost anywhere from $20 for small slabs to $100 for dining tables. Table tops usually cost $50 for smaller tops to around $200 on large tops over 10′. The amount of material that needs to be removed often dictates the price as well. The condition of the slab (i.e. amount of cupping or warping) can affect the time and cost as well.
