Fill and grading planner
Estimate fill dirt for grading and low spots.
Measure the area and average fill depth, then calculate bulk yards and an approximate delivered weight.

How this estimate is calculated
This is a planning estimate. Soil weight changes with moisture and composition. Confirm product volume, load limits, site conditions, and delivery requirements before ordering.
A reliable estimate in four steps
Measure once. See the math. Buy with confidence.
- 1Choose the project shape
Select the geometry that best matches the area you plan to fill.
- 2Enter measured dimensions
Use US or metric units and adjust individual fields when needed.
- 3Review the waste allowance
Use the project suggestion or enter a value that matches site conditions.
- 4Compare purchase options
Use the recommended bag count or bulk quote quantity as a starting point.

Planning guidance
Common topsoil estimate questions.
How many tons are in a cubic yard of fill dirt?
A cubic yard often weighs roughly 1.0–1.4 tons, but moisture, compaction, and soil composition can change the weight substantially.
Does this calculator include compaction?
The adjustable allowance can cover settling and compaction. Many fill projects use 10–20%, but confirm the correct factor with the supplier or site professional.
How much extra topsoil should I order?
A 5–10% allowance is a practical starting point for settling, uneven grades, and measurement error. Use 10–15% for irregular areas or uncertain depths.
Should I buy topsoil in bags or in bulk?
Bags are convenient for small repairs and a few planters. Around half a cubic yard, compare prices. For one cubic yard or more, bulk delivery is usually easier and more economical.
