About QuantityCalcs
QuantityCalcs is a set of 64 free calculators for working out how much material a building or landscaping job needs, and roughly what it costs in your state.
Each calculator shows the formula it uses and a worked example, so you can check the math yourself. Price figures come from published national cost guides adjusted by each state's price level — see how we calculate.
