About This Tool
Introduction
Landscaping projects live or die on getting the right amount of mulch — too little means a return trip to the yard, too much means wasted money. Trencada's free Mulch Calculator takes your bed's length, width and depth, applies a waste allowance for settling and spillage, and tells you exactly how many cubic yards you need, how many 2-cu-ft bags that equals, and what it should cost. It runs entirely in your browser — free, no signup.
