Free Soil Calculator – Cubic Yards & Bags

Soil Calculator Guide

The Soil Calculator estimates cubic yards and bags of topsoil, garden soil, fill dirt, or compost for your landscaping and gardening projects. Enter area dimensions and depth for instant volume and weight estimates.

Soil depth varies by project: 4–6 inches for new garden beds, 2–3 inches for topdressing lawns, 8–12 inches for raised beds. Mix compost at 20–30% by volume with native soil to improve drainage and nutrients.

Topsoil and garden soil are sold by the cubic yard (bulk) or in bags (1 cu ft). Bulk delivery is more economical for projects over 3 cubic yards. Soil settles 10–15% after watering, so order slightly more than calculated. Avoid working with soil when it is waterlogged.
