Fill Dirt Calculator
Estimate fill dirt for grading, leveling and backfilling. This calculator adds an adjustable compaction allowance so the order quantity can account for material settling after placement.

Planning estimate only. Confirm local prices, supplier specifications and site conditions before ordering.
Your estimate
Compaction and truck capacity vary by material and hauler. Use supplier values when available and treat truckloads as a planning estimate.

How the fill dirt calculator works
Compacted volume = area × depth. Loose order volume = compacted volume × (1 + compaction allowance).
For a better estimate
- Use an average depth when the site varies.
- Compaction depends on soil type, moisture and equipment.
- Ask the supplier for truck capacity and material density if you need more precise load counts.

Frequently asked questions
How do I calculate fill dirt?+
Calculate the volume of the space to fill, convert it to cubic yards and add an allowance for compaction and grading.
Why add a compaction allowance?+
Loose dirt occupies more space before it is compacted. The required allowance varies by material and site conditions.
How many cubic yards fit in a dump truck?+
Truck capacity varies significantly. Enter the actual capacity from your supplier or hauler for a more useful estimate.
