Metal Carport Cost Calculator

A carport is a roofed structure that protects a motorcar from the weather. It is usually an open-sided shed with one or more walls. Carports are more common in warm climates where they can provide relief from the sun and rain. In cold climates, they are often used to store cars during the winter.

A carport can be made of various substances, including metal, plastic, or wood. It is often attached to a house or garage but can also be standalone. The cost of a carport depends on its size, material, and whether it is attached or standalone.

To calculate the cost of a carport, you will need to know its dimensions (width, length, and height), the type of material you want to use (metal, plastic, or wood), and whether you want it to be attached or standalone.

Different Carport Types

Carports come in different styles, including:

Gable Roof Carports

Gable Roof Carports

A gable roof carport has a peaked roof, the most common types of carport. This type of carport is great for protection from the sun and rain. It is also great for when you want to add extra protection to your auto. The carport roofs help deflect the wind and keep the rain off your motorcar. They also help keep the snow off your auto in the wintertime.

Flat Roof Carports

Flat Roof Carports

A flat roof carport is the most popular type of carport. It has a simple, rectangular design and can be attached to your house or garage. Flat-top carports are a great way to add extra parking to your home without building a traditional garage. They’re also an excellent choice if you live in an area with a lot of wind or snow, as the flat roof will help keep your carport from being blown away.

Freestanding Carports

Freestanding Carports

A freestanding carport is a standalone permanent structure that is not attached to your house or garage. Freestanding carports are a great choice if you have a lot of lands and need a place to store multiple vehicles. They’re also a good choice if you want to be able to move your carport around, as they can be disassembled and reassembled quite easily.

Hip Roof Carports

Hip Roof Carports

A hip-roof carport has a pyramid-shaped ceiling. This ceiling has slopes on all four sides, with lower eaves than the ridge. Hip roofs are more aesthetically pleasing than flat or gabled roofs and offer better protection against the elements. However, they are also more expensive to build.

Skillion Carports

Skillion Carports

Skillion carports are a type of top that has a single sloped roof line. This makes them a popular choice for property owners who want to add extra shelter but don’t want something too bulky or obstructive. Skillion roofs are also known as shed roofs or lean-to roofs.

Carports Cost Calculator

The cost of building a carport varies depending on the size, substance, and design of the carport. The average cost to build a carport is between $2000 to $10,000.

Most important factors when it comes to determining the cost of a carport:


An important factor to consider while building a metal carport is size. The cost of building the carport will increase if you want a bigger carport. This is mostly because the bigger carports need more space and labor for installation.


The material you choose to build your carport determines how long it will last. Therefore, you must choose one accordingly.

Most carports made with metal or wood will be more expensive than ones made with plastic or polyethylene. The type of ceiling you choose will also impact the price.


Many people need extra customization while installing attractive carports to fit their specific requirements. However, if you’re going to customize your carport, you must know that the price of metal carport installation will eventually increase because of the extra work involved.

Location-specific requirements

The area you live in will also affect the price of building the metal carport. You will have extra requirements in some areas, like local building code permit fees and site preparation. You can contact your contractor to know about the extra costs involved in building a carport in your region.

A flat-roof carport will be less expensive than one with a pitched top. Finally, the design of your carport can also affect the cost. A simple, rectangular carport will be less expensive than one with a more complex design.

Cost to Build a Carport by Type of Construction

A carport is a great way to protect your auto from the elements. It can be freestanding or attached to your home.

When it comes to constructing a carport, there are two ways:

  • Prefab construction
  • Custom construction

Pick the one that works best for your needs. Both kinds may be utilized with a variety of materials and provide you with a variety of designs.

Prefab Carport Cost

The cost for a prefab carport can vary greatly, from around $2,000 up to $7,000 or more. This is because there are many sizes, styles, and substances to choose from.

One of the main benefits of opting for a prefab carport is that you have a wide range of choices regarding style and material.

You can get a wooden carport that perfectly matches the style of your house, or go for something more modern in metal or plastic. Sizes also vary greatly, so you can find one perfect for your needs – whether you’re looking to cover just one parking space or an entire driveway.

Custom Carport Cost

Custom metal carport costs vary depending on size, shape, and style. For example, a basic cellar with no extras or customized features will run around $4,000. However, if you want something more unique such as a curved top or specific sizing/shape, the cost can increase to $12,000.

Additionally, if you would like extra features such as electric wiring or insulation installed in your cellar, those costs will also be added.

Carport Cost per Square Foot

Carports can be found in many designs and sizes. The important thing in a cellar is how much space you need. It can be for a motorcar or many automobiles, the space to enter and exit the automobile, space for your other tools to store, etc. The range for your cellar per square foot can be between $15 to $20, or it can go above $35 per sq. ft.

The cost also depends on the type of cellar, such as the prefab or custom cellar. Prefab carports are less expensive than custom ones. Prefab costs can be around $10 to $15.

Regarding custom carports, the price per sq. ft can start from $15 to $35 or above.

Now that you know how much the carports cost, an sq. ft., We will mention some average sizes and their costs to understand them better.

Cost to Build a Carport by Number of Cars

Additionally, for a two-car carport, you can expect to pay anywhere from $1,200 to $2,000. And for a three-car carport, you can expect to pay anywhere from $1,800 to $3,000.

The exact cost will depend on the substances you choose and the complexity of the design. If you’re looking for something simple, you can probably choose to spend less. But if you want something more elaborate, be prepared to spend more.

The size of the carport can be 30 feet by 20 feet, 40 feet by 20 feet, or even 50 feet by 20 feet. The larger the carport, the more it will cost. But a three-car carport can be a great way to protect your vehicles and save money in the long run.

Four-Car Carport Costs

Four-Car Carport Cost

The average cost for a custom four-car carport is $12,000 to $28,000. However, you can buy a prefabricated carport for as little as $8,000 to $12,000. The size of the cellar will be 40 feet by 20 feet. This is a perfect choice for metal buildings and duplexes.

Carport Cost by Material

The cost of a cellar largely depends on the material used to construct it. Carports made from wood, aluminum, steel, concrete slab, and a blend of substances will vary in cost depending on the materials’ quality.

Each material has its own identity and benefits, so choosing the one that best suits your needs and budget is important.

Below we will mention the three most used materials for carports.

Metal Carport Prices

When it comes to metal carports, there are a few things that you need to keep in mind. First, the average price will range anywhere from $10-$30 per sq. ft. This depends on whether you want a prefab or go custom. If you go with a prefab, it will be more like $10-$15 per sq. ft. However, if you go custom, it will be more like $15-$30 per sq. ft. Metal carports are made of many other materials such as aluminum, steel, and metal composites.

Polycarbonate Carports

Polycarbonate carports are becoming increasingly popular among homeowners looking for an affordable and durable option for their homes.

Polycarbonate is a durable plastic material that is lightweight and impact-resistant. This makes it an ideal material for a cellar, as it can withstand heavy winds and snow without collapsing. Polycarbonate carports typically cost between $12 and $15 per sq. ft for prefabricated kits or $15 to $20 per sq. ft for custom-built structures.

Wood Carport Prices

The cost of a wood carport depends on the size, type, and features you choose. A prefabricated carport costs between $15 and $20 per sq. ft, while a custom-made cellar typically starts at around $20 per sq. ft. The cost increases if you add extra material such as gables, eaves, or dormers. You can expect to pay around $30 per sq. ft for a high-end custom carport made from premium materials.

Wood carports are most popular among home and business owners because they protect them from the sun, wind, and rain. Wood carports are also very versatile, as they can be designed to match the style of your home or business.

Labor Cost to Build a Carport

The labor cost to build a cellar is typically around $8 to $10 per sq. ft of the total project. This means that for a typical-sized carport measuring 10 feet by 20 feet, the labor cost would be between $160 and $200. These costs will vary depending on the size and scope of the project, but this should give you a rough idea of what to expect.

By comparison, the materials for such a project would typically run between $15 and around $30 per sq. ft, so you can see that labor makes up a significant portion of the overall cost. Hiring a professional contractor to handle your cellar construction is always recommended, as they will have the experience and expertise necessary to get the job done right.
