Why trust these numbers?
Every calculator on EstimateYard shows its work: the formula, the material assumptions (bag yields, densities, waste factors), and the sources and date behind every price. Estimates use national-average prices refreshed on a schedule — the “last updated” stamp is on every tool — and the math follows standard industry practice. Your local supplier’s quote is always the final word; our job is to get you to that conversation knowing what you need and what it should cost.
