Trying to level a sloped yard, raise a low area, expand a driveway or prepare a building pad?
Before ordering fill dirt, you need to answer two questions:
- How much fill dirt do I actually need?
- How much will it cost to have that amount delivered to my property?
Sloped areas are slightly harder to calculate than flat areas because the depth changes from one side to the other. But for a simple, consistently sloped area, you can estimate the volume using an average-depth or wedge calculation.
For homeowners, landscapers and small contractors searching for fill dirt near me, bulk fill dirt delivery, fill dirt for sale near me, fill dirt prices near me or a truckload of fill dirt, calculating the quantity first helps you avoid paying for an unnecessary second delivery—or ordering far more dirt than the project needs.
Aggregate Markets lets you check bulk fill dirt and other locally available materials for delivery directly to your home or job site.


Quick Fill Dirt Calculator for a Slope
If the area starts at approximately zero fill on one end and gradually increases to a maximum depth on the other, use:
Length × Width × Maximum Depth × 0.5 = Cubic Feet
Then:
Cubic Feet ÷ 27 = Cubic Yards
Example
You want to level an area that is:
- 50 feet long
- 18 feet wide
- 3 feet deep at the lowest end
Calculation:
50 × 18 × 3 × 0.5 = 1,350 cubic feet
Then:
1,350 ÷ 27 = 50 cubic yards
Your estimated compacted finished volume is about 50 cubic yards.
However, that does not automatically mean you should order exactly 50 cubic yards of loose fill dirt.
The delivered material may change volume when handled, moisture-conditioned and compacted. The actual difference varies by material and project conditions.
For larger fills, ask the supplier or contractor what conversion or shrink factor they recommend for the specific material being delivered.
Why Calculating Fill Dirt on a Slope Is Different
For a flat area with a consistent depth, the calculation is simple.
For example:
Length × Width × Depth
But imagine you're leveling a backyard that slopes downhill.
At the high end, you might need almost no fill.
At the low end, you might need 3 feet.
Using 3 feet as the depth across the entire area would dramatically overestimate the amount of dirt required.
If the slope is relatively consistent, you can use the average depth.
If one side requires zero fill and the other requires 3 feet:
Average depth = 1.5 feet
Then:
50 × 18 × 1.5 = 1,350 cubic feet
This produces the same result as the wedge formula.
Fill Dirt Wedge Formula
For a simple triangular slope:
Cubic Feet
Length × Width × Maximum Fill Depth ÷ 2
Cubic Yards
Length × Width × Maximum Fill Depth ÷ 2 ÷ 27
Or:
L × W × H × 0.5 ÷ 27
This works best when the existing slope changes fairly consistently from one end of the project to the other.
What If the Ground Is Uneven Instead of a Perfect Slope?
Real yards rarely look like geometry diagrams.
You may have:
- dips
- humps
- drainage channels
- uneven excavation
- multiple slopes
- an irregular property boundary
In that situation, don't rely on one maximum depth measurement.
A better DIY estimate is to divide the site into smaller sections.
For example, split a 60-foot yard into three 20-foot sections.
Measure the approximate fill depth in each section:
| Yard Section | Section Size | Average Fill Depth | Estimated Volume |
|---|---|---|---|
|
Upper Section
Shallowest part of the slope
|
20 ft × 18 ft | 0.5 ft |
6.7 yd³
20 × 18 × 0.5 ÷ 27
|
|
Middle Section
Moderate fill depth
|
20 ft × 18 ft | 1.5 ft |
20 yd³
20 × 18 × 1.5 ÷ 27
|
|
Lower Section
Deepest part of the slope
|
20 ft × 18 ft | 2.5 ft |
33.3 yd³
20 × 18 × 2.5 ÷ 27
|
| Estimated Finished Fill Volume | ≈ 60 yd³ | ||
Next step: use the total cubic-yard estimate to compare fill dirt delivery near you, then confirm how much loose material should be ordered to reach your finished compacted volume.
Calculate each area separately and add the volumes together.
This usually produces a much better material estimate than treating an irregular yard as one large wedge.
How Much Fill Dirt Should You Actually Order?
Your calculated cubic-yard figure represents the finished volume you need to create.
But fill dirt is generally delivered loose.
Once the material is:
- dumped
- spread
- moisture-conditioned
- driven over
- compacted
its volume can change.
There is no trustworthy universal rule saying every fill dirt project needs exactly 10%, 15% or 25% extra.
The amount depends on:
- soil type
- moisture
- how loose the delivered material is
- required compaction
- equipment being used
- project specifications
For a small landscaping project, a modest ordering allowance may help prevent running short.
For a large project requiring dozens of cubic yards, ask about the loose-delivered volume versus expected compacted volume before placing the order.
That can prevent a very expensive estimating mistake.
What Type of Fill Dirt Should You Buy?
“Fill dirt” can describe several different materials.
What you should order depends on what you're building.
General Fill Dirt
Good for many projects such as:
- raising low areas
- filling depressions
- rough yard grading
- landscaping projects
- creating volume below a topsoil layer
This is generally what homeowners mean when they search for bulk fill dirt near me.
Clean Fill Dirt
Clean fill is generally selected to avoid unwanted trash, demolition debris or unsuitable material.
Definitions vary by jurisdiction and supplier, so check what is actually included.
For residential properties, you should know what is being dumped before accepting a large load.
Select or Compactable Fill
If the fill will support:
- a driveway
- parking pad
- shed
- patio
- slab
- structure
- heavily traveled area
you may need a more predictable select fill, structural fill or compactable fill material rather than inexpensive general-purpose dirt.
Don't choose solely by price when the material will eventually carry a load.
Can I Use Fill Dirt to Level My Backyard?
Yes.
This is one of the most common uses for bulk fill dirt.
For example, if you want to turn a sloping part of a backyard into a flatter usable area, you may use fill dirt to build most of the required elevation.
If you want grass or landscaping afterward, the common approach is:
Fill dirt for volume → topsoil for the finished growing layer
Using screened topsoil for the entire depth of a large fill can become unnecessarily expensive.
How Much Dirt Do I Need to Raise My Yard?
For an area that needs approximately the same additional depth throughout:
Length × Width × Depth ÷ 27 = Cubic Yards
Example: Raising a Yard 6 Inches
Area:
40 × 30 feet
Depth:
6 inches = 0.5 feet
Calculation:
40 × 30 × 0.5 = 600 cubic feet
600 ÷ 27 = 22.2 cubic yards
So you need approximately 22 cubic yards of finished fill volume, before allowing for the characteristics of the delivered material.
That's already a bulk-delivery project—not something most homeowners want to move in bags.
How Much Fill Dirt Do I Need for a Driveway Extension?
Suppose you're extending a driveway into an area measuring:
20 feet × 12 feet
The existing ground slopes from zero to 18 inches lower at the opposite edge.
Convert 18 inches to feet:
18 ÷ 12 = 1.5 feet
Then:
20 × 12 × 1.5 × 0.5 = 180 cubic feet
180 ÷ 27 = 6.7 cubic yards
That gives you the approximate volume needed to level the slope.
However, if the area will support vehicles, ordinary landscape fill may not be sufficient as the finished structural base.
You may need:
approved compactable fill → aggregate base → driveway surface
depending on the site and driveway construction.
How Much Fill Dirt Do I Need for a Shed or Building Pad?
The math is similar, but the material requirements become more important.
If you're creating a pad that will support a structure, you should not simply order the cheapest dirt available and dump it until the area looks level.
The fill needs to be:
- suitable for compaction
- placed correctly
- compacted as the pad is built
- protected from poor drainage
For structural projects, follow the requirements for the building, foundation or local code.
Should You Put Fill Dirt Behind a Retaining Wall?
Be careful here.
A retaining wall needs drainage.
Ordinary fill dirt packed directly behind the wall can trap water and increase pressure.
Many retaining-wall designs instead use:
clean drainage stone near the wall + properly specified backfill farther behind it.
If you're leveling a slope with a retaining wall, your order may therefore include more than one material.
For example:
- drainage stone
- compactable fill
- topsoil
- decorative gravel or mulch
Calculate each separately rather than ordering one giant load of generic dirt.
How Should Fill Dirt Be Compacted?
The worst method is:
dump several feet of dirt → compact only the top
The surface may look solid while the material underneath remains loose.
Fill is normally built up in lifts, meaning manageable layers that are spread and compacted before the next layer is added.
The appropriate lift thickness depends on the soil, equipment and construction requirements.
Compaction improves soil strength and reduces the potential for long-term settlement, which is especially important beneath driveways, pads and embankments.
For a small residential grading project, contractors often use equipment such as:
- plate compactors
- jumping-jack compactors
- rollers
- compact track loaders
The appropriate equipment depends on the type of soil and project.
Should You Order Fill Dirt by the Yard or Ton?
Dirt is often discussed in cubic yards because you're trying to fill a volume.
But suppliers may sell or invoice certain materials by:
- cubic yard
- ton
- truckload
Do not assume one cubic yard always equals a fixed number of tons.
Weight changes significantly with:
- soil composition
- moisture
- clay content
- rock content
The safest approach is:
- calculate the volume you need in cubic yards;
- select the actual fill material;
- let the supplier or marketplace convert that quantity using the material's expected density.
How Many Yards of Fill Dirt Fit in a Dump Truck?
There isn't one universal “dump truck load.”
Truck capacities vary considerably.
A project requiring only a few yards may use a smaller truck, while a project requiring dozens of yards may require multiple larger loads.
This matters because delivery can become a major part of the total project cost.
If your calculation says you need 50–60 cubic yards, you're no longer comparing the price of dirt alone.
You're comparing:
material + trucking + number of loads + delivery distance
How Much Does Fill Dirt Cost Near Me?
Fill dirt pricing varies by location and material.
The delivered price can depend on:
- quantity
- dirt type
- supplier
- delivery distance
- truck size
- number of loads
- site access
This means searching for a national “fill dirt price per yard” only gives you part of the answer.
A supplier with cheaper dirt but a much longer haul may cost more by the time the material reaches your property.
The number that matters most is:
Delivered Price to Your Address
That's especially true when ordering 10, 20, 50 or more cubic yards.
Where Can I Buy Fill Dirt Near Me?
You have several options:
- excavation companies
- landscape supply yards
- soil suppliers
- aggregate suppliers
- local hauling companies
- online bulk-material marketplaces
The challenge is that availability changes by location.
One supplier may have inexpensive general fill.
Another may have screened fill, clay fill or select fill.
A third may have the best material but be too far away for economical delivery.
Aggregate Markets lets homeowners, contractors and property managers enter their location and search for bulk fill dirt and other materials available for delivery near the project.
Depending on your area, available materials may include:
- fill dirt
- clean fill
- screened fill
- select fill
- structural fill
- topsoil
- sand
- gravel
- crushed stone
For large projects, compare the delivered total, not just the advertised price of the dirt.
Before Ordering a Truckload of Fill Dirt
Check these five things first:
1. Calculate the finished volume
Measure length, width and average depth.
For a consistent slope, use the wedge formula.
2. Choose the correct material
General yard grading and structural fill are not necessarily the same product.
3. Account for delivered vs compacted volume
Ask how the supplied material behaves after placement and compaction.
4. Check truck access
Consider:
- overhead wires
- branches
- gate width
- soft lawns
- septic systems
- slopes
- culverts
- tight turns
A loaded dump truck is substantially heavier than a passenger vehicle.
5. Decide where the dirt will be dumped
Bulk delivery normally means the material is dumped in an accessible location.
It does not necessarily include:
- spreading
- grading
- compacting
- excavation
- final landscaping
Plan the equipment and labor before the truck arrives.
Fill Dirt Calculation Example: Full Sloped-Yard Project
Let's use the original example:
Project
50-foot-long × 18-foot-wide area
Slope:
0 feet of fill at the high side
3 feet of fill at the lowest side
Step 1: Calculate Wedge Volume
50 × 18 × 3 × 0.5
= 1,350 cubic feet
Step 2: Convert to Cubic Yards
1,350 ÷ 27
= 50 cubic yards
Step 3: Determine Material
If this is simply raising and landscaping a yard:
Bulk fill dirt may make up the majority of the project.
If grass will be planted:
Plan for an appropriate topsoil finish layer separately.
Step 4: Determine Delivered Quantity
Ask the supplier how much loose material should be ordered to produce approximately 50 compacted cubic yards of the chosen fill.
Do not automatically multiply by a generic online percentage.
Step 5: Compare Delivery Options
A project this size will likely involve multiple loads depending on truck capacity and material density.
Compare the total delivered cost before ordering.

Final Answer: How Much Fill Dirt Should You Order?
For a simple slope, calculate:
Length × Width × Maximum Fill Depth × 0.5 ÷ 27
to estimate cubic yards.
But don't stop at the calculator.
Before placing the order, confirm:
- which type of fill you need;
- whether the calculated amount represents finished or loose volume;
- how the material will compact;
- how many truckloads are required;
- what delivery will cost to your exact location.
If you've already measured your project, the next step is not another calculation.
It's finding the right fill dirt, in the right quantity, delivered to your property.

Frequently Asked Questions
How do I calculate fill dirt for a slope?
For a consistent slope that starts near zero fill and reaches a maximum depth at the opposite side, use:
Length × Width × Maximum Depth × 0.5 ÷ 27
This gives an estimate in cubic yards.
How many cubic yards of fill dirt do I need?
Multiply the area's length, width and average fill depth in feet, then divide by 27.
Should I order extra fill dirt for compaction?
Possibly, but there is no single percentage appropriate for every soil. The difference between loose and compacted volume depends on the material, moisture and required compaction.
Where can I buy fill dirt near me?
Search local dirt, aggregate and landscape suppliers or use a bulk-material marketplace that can match your delivery location with nearby available materials.
Can I get fill dirt delivered?
Yes. Bulk fill dirt is commonly delivered by dump truck. The appropriate truck depends on the quantity, material weight, local supplier and property access.
What is the cheapest fill dirt?
General-purpose fill is often cheaper than screened topsoil or engineered materials, but delivery distance can have a major impact on the final price.
Is fill dirt sold by the yard or ton?
Both are possible. Fill projects are commonly calculated in cubic yards, while suppliers may price or transport material by volume, weight or truckload.
How much is a truckload of fill dirt?
There is no single national truckload price because truck capacity, supplier distance, material type and local rates vary. Compare delivered pricing for your project location.
Can I use fill dirt to level my yard?
Yes. Fill dirt is commonly used to build elevation and correct low areas. If grass or plants will grow there, finish with an appropriate layer of topsoil.
What fill dirt should I use under a driveway?
A driveway or parking area may require select, structural or otherwise suitable compactable fill rather than general landscaping fill. The required material depends on soil conditions and the planned pavement or aggregate system.
