    Budget scenario

    Add your current local costs

    Use a current supplier subtotal or reuse a priced calculator result, then add optional delivery, tax and contingency. Home Measure Lab does not fetch or guess live prices.

    Uses the calculator's user-entered price result when one is currently shown; otherwise enter a current supplier subtotal.
    Material subtotal$0.00
    Delivery / fees$0.00
    Tax$0.00
    Contingency$0.00
    Planning total$0.00

    Enter a current supplier subtotal or reuse a priced calculator result.

    Budget values are local planning inputs, not live quotes. Verify tax treatment, delivery, labor and supplier pricing before purchasing.

    Choose the right tool

    When to use this calculator

    You need general topsoil volume for lawns, grading or a broad landscape area.

    Use a different calculator when

    Use Garden Bed Soil for a raised/rectangular bed with settling allowance, or Compost for amendment/top-dressing.

    Methodology

    Formula & assumptions

    Area

    length × width

    Rectangular planning area.

    Soil volume

    area × depth

    Depth is converted from inches to feet.

    Bulk volume

    cubic feet ÷ 27

    Shows cubic yards for bulk ordering.

    Bag count

    cubic feet ÷ bag volume, rounded up

    Enter the actual cubic-foot or liter volume on your soil bag.

    How to measure this project

    Measure the surface area that will receive new soil and choose the finished depth of added material. If you are filling low areas rather than applying a uniform layer, split the project into sections with different average depths.

    Before you buy materials

    Loose soil can settle after placement and moisture affects delivered weight. Bulk suppliers usually sell by cubic yard or cubic meter; bagged products are labeled by volume. Use volume for planning and avoid assuming a fixed weight conversion across soil blends.

    Questions

    Frequently asked questions

    How many cubic feet are in a cubic yard?

    There are 27 cubic feet in one cubic yard. The calculator uses that exact volume conversion for bulk ordering.

    Can I convert topsoil volume directly to tons?

    Not reliably without a material-specific bulk density. Soil weight changes with composition, moisture and compaction, so ask the supplier when ordering by weight.

    Why does the bag count round up?

    A fractional bag generally cannot cover the remaining volume, so the purchase quantity rounds to the next whole package.
