Topsoil Calculator — Cubic Yards, Tons & Bags

Lawn leveling, raised beds, new lawns — volume, tonnage and bag counts.

Quick answer: Enter bed size and depth to get topsoil in cubic yards, cubic meters, tons and 40-pound bag counts with optional cost — order the right delivery first time.

📏 Topdressing rule: never bury grass crowns — 1/4 to 1/2 inch at a time, then let it grow through. New beds take 4–6 inches worked into the top layer.

How to use

  1. Measure the bed: length × width, or enter the total area directly.
  2. Set the depth in inches (or cm in metric) — topdressing 2 in, new beds 4–6 in.
  3. Read cubic yards, cubic meters, tons and 40-lb bag counts.
  4. Optional: enter a per-yard or per-bag price for the total cost.

About this tool

Whether you are leveling a lawn, filling raised beds or repairing ground after construction, topsoil is sold three ways — by the cubic yard, by the ton and by the bag — and this topsoil calculator converts your project into all three so you can price whichever your supplier quotes. Enter the bed as length × width or a direct area figure, set the depth — about 2 inches for topdressing, 4 to 6 for new beds and leveling — and get cubic yards, cubic meters, tons at roughly 1.35 tons per cubic yard, and the count of 40-pound bags if you would rather haul than have it delivered. Optional price fields give the delivered or bagged cost instantly. Real soil varies enormously in moisture and density, so treat the tonnage as an order-level estimate and confirm with your supplier before the truck rolls. Everything is computed on your device — nothing is sent anywhere.

FAQ

How much topsoil do I need for a new lawn?
Spread 4–6 inches over poor subsoil for a new lawn from seed or sod — a 1,000 sq ft yard at 4 inches works out to about 12.3 cubic yards. For merely topdressing an existing lawn, 1/4 to 1/2 inch is plenty, which is barely 1 yard per 1,000 sq ft.
How much does a cubic yard of topsoil weigh?
Roughly 1.2–1.5 tons depending on moisture — this calculator uses the common 1.35 tons per cubic yard ordering figure. Saturated soil can weigh meaningfully more, so spring deliveries cost more to haul and suppliers price accordingly.
How many 40-lb bags are in a cubic yard?
A 40-lb bag of topsoil yields roughly 0.75 cubic feet, and a yard is 27 cubic feet, so about 36 bags per yard. Past a dozen bags, bulk delivery is almost always cheaper per yard and infinitely easier on your back.
How much does topsoil cost?
Bulk topsoil typically runs $15–$60 per cubic yard delivered depending on region and quality — screened topsoil sits at the upper end. Bagged topsoil works out to $60–$100+ per yard equivalent, which is why bags only make sense for small patch jobs.
Is cheap fill dirt the same as topsoil?
No. Fill dirt is subsoil — low organic matter, compacts well, grows little. Topsoil is the biologically active top layer. For lawns and beds you want screened topsoil; fill dirt belongs under it, not on it. Ask for a sieve size and organic content if the supplier offers options.
