An online gravel calculator helps to estimate how much gravel in volume and weight you need to complete your earthwork project. However, by using this online gravel cost calculator you come to know how much the gravel material will cost you!

Well, if you are going to improve the beauty of your surface area with pea gravel materials, this gravel or aggregate calculator is the right choice to do so. Now, give a try to this free gravel estimator will that tells you how much stone, rock, gravel or material of your choice you need to complete your project.

It doesn’t matter whether you want to know how much stone, rock, or gravel material you need to complete the project, “this gravel quantity calculator will calculate the precise measurements for the material of your choice”.

Read on!

This online gravel calculator estimates the volume & weight of gravel needed and here we have manual calculations for both. Let’s begin!

And, if you concerned to determine how much mulch you need for a given area at a specified depth, then this online mulch calculator works best for you.

To calculate the volume needed, follow the given steps:

- Measure the length & width of the area for which you going for the construction.
- Find out the area of the surface from length & width. \((A = L \times W)\).
- Determine the depth of the surface.
- Find out the volume by multiplying the area and depth.
- The volume obtained is the volume needed for the gravel to complete the project.

Let’s have an example:

**Example**:

A surface has \(18 ft\) long and \(21 ft\) wide with a depth of \(10 ft\). Then how much gravel do I need?

**Solution**:

\(L = 18 ft\)

\(W = 21 ft\)

\(D = 10 ft\)

So, find the area by,

\(A = L \times W\)

\(A = 18 \times 21\)

\(A = 378 ft^2\)

Now,

Calculate the volume by using the formula:

\(V = A \times D\)

\(V = 378 \times 10\)

\(V = 3780 ft^3\)

To calculate the weight needed, using the formula:

\(Density = \frac {mass}{volume}

\(mass = Density \times volume\)

You don’t have to remember the density; our gravel calculator sets this value by default.

Let’s try an example:

**Example:**

If the volume needed is \(3780 ft^3\) and the density is \(104.88 lb/ft^3\), then find the weight needed?

**Solution:**

Here,

\(Density = 104.88 lb/ft^3\)

\(Volume = 3780 ft^3\)

So,

\(mass = Density \times volume\)

\(mass = 104.88 \times 3780\)

\(mass = 396446.4 lbs (198.223 tons)\)

If a small project that uses pea gravel elements about 200 square feet coverage, the cost should be between $300 and $400, with an average cost of $350. However, this cost for pea gravel drops considerably for larger quantities that you will need for a landscaping project.

The general range of pea gravel cost for a cubic yard of plain pea gravel is about $15 to $75, and a ton will cost about $10 to $50. When it comes to colored variety, it is expected to add an extra $20 to $50 to those prices. For your earthwork projects, simply consider the online gravel calculator, and lets it do the instant calculations for pea gravel.

Also, try this online sand cost estimator that quickly estimates the total cost of the sand that you required to complete your earth projects.

According to their different size & shape, they can be classified into following:

Naturally a mixture of gravel with sand or clay present in the rivers or streams. It is also called “bank run” or “river run”.

This type is located on the valley above the stream, indicating the previous position of stream when it was at higher level.

River rock is generally round shaped and polished stones that are often covered with the stream or river bed. It is used as concrete aggregate and in paving the surfaces.

Crushed stones type is the mixture of crushed rock pieces and stone. Crushed rock also known as “crusher run” “shoulder stone” “DGA (dense grade aggregate)” “QP (Quarry Process)” usually in the size of ¾ inch or less. Its common use is in surfacing of roads and driveways. This type may be made from granite, limestone and from other rocks.

The type of gravel with the diameter of 2-8mm, termed as fine gravel.

The fine & crushed stones from the final stage of screen separation, such that stone is not separated from dust.

This type left behind after the removal of the fine particles from the gravel.

It is also known as pay gravel, is the high concentration of gold and other precious metals with gravel.

It consists of rounded, small stones commonly used in concrete surfaces. If you are going to gravelling your path with pea gravel elements, then this pea gravel calculator helps you to determine the required quantity and volume of pea gravel for your work.

This type consists of the coarse gravel carried from the high places by mountain streams and deposit on flat surfaces, where water runs slowly.

This type is usually found on the plateau or other regions.

For convenience, try this online aggregate calculator that lets you calculate the total weight, volume and cost of gravel required for specific gravel types.

The online gravel estimator allows you to calculate how much gravel you need to convert a rectangular area or circular area, the given steps will help you in using this free online calculator:

Input:

- First of all, choose the area that you need to fill with gravel material, it can either rectangular or circular
- Now, you just have to put the values into the designated field of this online grave calculator
- Tap the calculate button

Output:

The online gravel estimator estimates:

- The volume needed for gravel
- The weight needed for gravel

**Note:**

It doesn’t matter whether you do gravel calculations for the rectangular or circular area, there you have an option field of price per unit mass. You just have to enter the price/unit of mass into this gravel cost calculator to determine the total cost of gravel you required for your project.

Also, the calculator-online provided a free online asphalt calculator that used to calculate the amount of asphalt you need to complete your project.

If you have an irregular shapes area for which you have to do calculations, it’s a bit more difficult but generally you have to divide it in the regular shaped sections. Then, do gravel estimations on regular shaped areas and sum them together.

A ton of gravel will cover according to the following measurements:

\(¼\) to \(½\) inch gravel = \(100\) square feet.

\(½\) to \(1\) inch gravel = \(90\) square feet.

\(½\) to \(2\) inches gravel = \(80\) square feet.

You should usually lay 10mm aggregate at the depth of 30-40mm, but it is increased to 50mm on the driveway. A larger aggregate will better bond together than the smaller.

- The density of gravel, loose, dry is equal to 95 lb/ft^3 or 1520 kg/m^3
- The density of gravel, with sand is equal to 120 lb/ft^3 or 1920 kg/m^3

Remember that a cubic yard (yd^3) is used to measure volume where a ton helps to measures weight. Usually, a yard of topsoil weighs about 1,800 pounds and a yard of gravel typically weighs about 2,200 pounds.

The construction materials are usually measured in cubic yards. All you need to multiply the length (L), in feet, by the width (W), in feet, by the height (H), in feet, and divide by 27. This formula will help to determine how many cubic yards of crushed stone you need. While using this formula, make sure that all of the given measurements are in feet.

Calculating rock needs:

Material |
Suggested Depth |
Coverage Area per 1 ton |

3”-8” rock | 3”-8” | 60 square feet |

1”-3” rock | 1”-3” | 80 square feet |

3/4”-1” screened gravel | 2” | 100 square feet |

5/8”-1/2” screened gravel | 2” | 120 square feet |

1/4-3/8” screened gravel | 2” | 140 square feet |

Typically, a cubic meter (m^3) gravel weighs about 1,680 kilograms or 1.68 tonnes. A square meter (m^2) of gravel with only a depth of 5cm weighs about 84 kg or 0.084 tonnes.

The cost of gravel ranges from:

- $10 to $50 per ton
- $15 to $75 per yard
- $1 to $3 per square foot
- $1,350 per truck-load that depends on the type of material, volume, and travel distance

It mixed with asphalt for road construction as well as mixing with and for the manufacturing of concrete. Its common use is to surface the roadways especially icy roads.

Yes, the crushed gravel drains well and is great in paving the blocks and in concrete for footpaths. So, if you have an area where water doesn’t drain, then add some crushed stone which is helpful for draining and for decorating feature.

In large projects, a miscalculation does happening too much, so even using this driveway gravel calculator, it is important to consult to professional. Now, it becomes to manage your road construction projects with the assistance of this free online gravel estimator.
