How to use these calculators
Each tool pairs a quantity calculator with a cost calculator. Start with quantities to know what to order, then price the job with rates from your own supplier or bids. Every price, density and waste factor is an editable input rather than a hidden constant, so you can match local conditions instead of accepting a national average.
