What type of formula do you use to estimate stone. I'm estimating more and more of these jobs and with the price of some decorative stone being so high, I've got to get pretty close.

Here's an example estimate: 3x20 bed, 3x15 bed, and 5x10 foot bed.

I figure two inches thick but how many tons would you estimate here?

First of all, you can't estimate by weight. Different decorative stone weighs different amounts. For example, lava rock is light compared to river rock.
A ton of lava rock covers about 250 sq ft @ 2 inches. A ton of river rock covers about 90 sq ft @ 2 icnhes. Most stone suppliers will be able to tell you coverage of each of their products.

I have not seen that calculator before. As far as I can understand, it still doesn't give you the weight. The original question asked for an estimate for how many tons for a given area.
