How this topsoil estimate works
Use this calculator to turn several measured beds or lawn sections into a volume you can compare with bulk soil or bagged soil. Start with the finished depth you want, then make the allowance and package details visible.
How to measure
- Measure the length and width of every bed or lawn section that needs soil.
- Enter the finished soil depth and choose the matching depth unit.
- Add paths, patios, or other uncovered spaces as exclusions, then enter bag volume only if you are buying bags.
How the estimate works
Multiply net area by depth to get base volume. Convert the result to cubic yards or cubic meters, then apply the selected allowance.
Worked example
At 1,000 sq ft and 3 inches deep, the base volume is 250 cu ft, or 9.26 yd³. A 10% allowance raises that to 275 cu ft, or about 10.19 yd³.
Before you buy
Use bulk pricing when a delivered cubic-yard price is available. For bags, use the volume printed on the bag and round to whole bags. Compare the supplied inputs rather than assuming one format costs less.
Package and supplier details
Bag fill volume, bulk delivery terms, soil blend, moisture, and settling can vary. Use the product label or supplier information for the package and price fields.
Assumptions
- The entered depth is applied evenly across the net area.
- The allowance is a planning buffer for settlement or small measurement differences.
- Bag and bulk cost are compared only when the matching prices are entered.
Limitations
This is a level-volume estimate. It does not model slopes, grading, compaction, soil blends, or final elevation checks.
