These calculators use the formulas of KOR's starter templates, the takeoff, estimating and scheduling software for residential construction. Every result comes with its calculation, number by number.
In KOR, you don't type lengths: you measure on your PDF plans and the quantities calculate themselves. Spacing, waste and sizes stay yours: every template can be edited.
