What is a Construction cost calculator?

A cost calculator is a software that uses regularly updated information about the various factors of construction (such as labor charges, cost of construction materials, cost of land, material price, and more).

An advanced algorithm that uses the inputs from your end to suggest the most accurate estimated cost for your project, if you need to know the precise details based on the exact site dimensions then you can visit the related links to read more about it like 30×40 House construction cost, 40×60 House construction cost etc.

One can visit our other pages which also have detailed information related to the possibilities of duplex house designing and duplex house construction of G+1 G+2 G+3 G+4 Floors along with possible cost estimation.

How to Use the Cost Calculator?

The cost calculator to calculate the cost of a duplex home is a highly intuitive, DIY tool that can be used by even the most technologically unsound person.

The software requires you to feed it with information such as the size of your plot, the location of the plot, materials to be used in the structure, type of doors, windows, painting, no. of rooms, type of house, flooring type, amongst other.

After you have feed the system with the information, within seconds, the tool suggests a detailed cost estimate. Here is a systematic way of using the software.

Systematic Procedure for Using the Cost Calculator:

Follow this link to go the cost calculator. Once you are on the page, you will find a range of fields marked in Orange, White, and Green.

The ones marked in Orange are parameters that display the various factors of construction and the fields marked in Green are selections you have made (except for first three variables where you need to select values, and they are displayed only in White).

Having cleared this aspect, let us proceed to each variable and the selection that is right for your construction if you want to see sample residential house plans for site dimensions such as 20×30 designs, 30×40 designs, 40×60 designs, and 50×80 designs.

Site Area/ Site Dimension/ Sq. Ft:

This the first and an essential aspect while using the cost calculator. It is crucial that you provide a correct site area or dimension. Providing the wrong area will completely throw off the estimated cost of the project.

Duplex house construction cost in Bangalore 20x30 30x40 40x60 50x80

A slight difference in the site diameter can have a completely different estimated cost. In the cost calculator, you have three options to fill the plot area – SITE AREA, SITE DIMENSION, and SQ. FT.

If you toggle-on site area, you can manually enter the area per square feet into the calculator, whereas toggling-on site dimension allows you to choose from a drop-down list of site dimensions such as 20×30, 20×40, 30×40, 30×50, 30×60, 40×60, 40×50, 50×80, 50×50, etc.

By toggling-on SQ. FT., you can choose from a set of site area embedded within the software. Use whichever method suits you and provide the exact information about the plot area or dimension and move to the next option.


We have extensively exaggerated the importance of site location in duplex house cost determination. As the price of land varies from one location to the other within the same city, you cannot adopt one price for various locations within the city.

For example, in Bangalore alone, the cost of land varies greatly from one region to the other. With a light on this aspect, the cost calculator requires you to feed it with the location of the site so that it can suggest the most accurate cost estimate. Use the drop-down list to select from hundreds of locations.

No of Floors G+1 G+2 G+3 G+4:

The number of floors you decide to build is also an essential factor that has an impact on the total cost of the project. If you choose an additional floor on the house, there are direct costs as well as the indirect cost that will increase such as labor wages, materials cost, and others.

Although the architect most probably will not charge any additional fees for design, you may have to increase the fees of the architect when the number of floors increases.

The algorithm within the cost calculator considers all these aspects when you select the number of stories in the building. Select the number of floors you want to build.

House Type Duplex House / Rental House:

The next variable factor you need to fill is the type of house you want to build. There are mainly two types of residential home – duplex and rental.

A duplex house construction is planned on two or more floors with an inside staircase connecting them, whereas a rental house is designed to be apartments that can be rented. In the duplex cost calculator, you have the two options and a hybrid combination of both. Select the options that suit your requirements.

BHK (Bedroom Hall Kitchen) 1Bhk/2Bhk/3Bhk/4Bhk:

The number of bedroom, hall, and kitchen in the house also plays a role in the cost estimate.

As you might assume, the more the number of rooms in the house, the more cost will be. In the cost calculator, you can select from 1BHK 2BHK 3BHK up to 4BHK.

Structure Bricks / Solid Cement Blocks:

The structure of the building is essential, you should take the advice of our architects before making the selection as some structures may be expensive now, but they may reduce cost in future by the form of reduced maintenance cost.

The options for materials available in our cost calculator are cement blocks (6’), cement blocks (8’), and bricks. Depending on the advice from the architect, make your selection.

Flooring Vitrified / Granite / Marble / Wooden:

Similar to the structure, you also have various options for flooring. You can go with the best price or the one that looks most luxurious.

The options available for you to choose are vitrified, granite, and marble + wooden.

Doors Solid wood / OST Doors:

In this section of the Duplex house construction cost calculator in Bangalore, you have to select the appropriate material for the doors. Here again, depending on the quality and the price you can make your selection.

It’s recommended that you search online for information on various materials and their features before making the selection. Once you have made your choice, proceed to the next option in the cost calculator.

Windows Teak wood / Sal wood / UPVC / Aluminum:

Similarly to the doors, you also have to choose the materials for the windows; the cost calculator provides you options such as sal wood, honne wood, Aluminum, UPVC and teakwood. Select the best choice for your house.

Painting Type:

The last option before you obtain the result of the cost calculator is the type of painting you would use on the house. The two options in the calculator are basic and premium.

Once you have filled all the information, click on the button that says “ CALCULATE DUPLEX CONSTRUCTION COST IN BANGALORE “ and scroll down for the total estimate and further down for a detailed breakdown of the cost estimate.

Factors that affect Duplex House Construction in Bangalore while building a Duplex House?

The issue of the cost of construction for a Duplex house is one of the foremost concerns of all parties involved in a duplex construction such as a client, contractors, structural engineers, labors, surveyors, and architect teams.
Budget factor of a house
It’s the job of the Architect or the Building contractors hired for the duplex construction to provide answers to such questions. However, this is easier said than done.

A home construction project is complex and involves variable factors that can change within a short period. Almost all of these elements of the construction of a house are beyond anyone’s control.

The most common and the first question most clients ask “What is the cost of construction or How much is the project going to cost me“.

Factors that affect the Construction cost of a Duplex house in Bangalore:

Fees of the Architect:

There are three significant ways an architect charges his or her fee for a project – per hour basis, a percentage of the total cost of the project, and a fixed sum.

In case the project is large, the architect will most likely charge between 3 – 5 percent of the total cost of the project. This can be a substantial amount and hence considered in the total cost of the project.

Fees of the Structural Engineer/Project Consultants:

A skilled engineer is pivotal to the success of a project; however, a reputed and skilled engineer will most likely charge a high amount of money for the project.

Nevertheless, it is worth the cost as the professional consultants can reduce the value of the project by ensuring every task is completed as per plan, and the project is not delayed. Therefore, the cost of the engineer should also be considered in the cost estimate.

Approvals / Plan Sanctions:

Before the commencement of any project, some approvals and sanctions need to be obtained from various government bodies like BDA, BBMP, BMRDA, Gram panchayat.

If you fail to do so, there might be heavy penalty levied on you. Additionally, the approvals can sometimes be costly and should be considered in the total cost estimate.

Size of construction:

The size of the building or built up area (BUA)plays a significant role in the total project cost as a large project generally extends over a long period and cost more.

Besides, the local workforce might not be sufficient for a large project and workforce might have to be brought in, from other parts of the country, which can be costly.

Hence, the size of the project and the availability of workforce is also a factor in total cost estimation.

Client’s Priorities:

The objective of any construction work is to satisfy the client. It is the client’s fund that is used in the construction.

Hence, the most pivotal factor that affects the cost of construction is the expectations of the client.

Cost of Construction Materials:

When we talk of construction materials, it includes the materials, shipping charges, and the taxes levied on the materials. Materials are one of the most expensive aspects of construction and their cost can change over time.

While estimating the cost of construction, it is necessary that you consider the most updated cost of materials including the allied charges.

Similar Project Completed Recently:

A project completed in the near past can be a good reference for the upcoming project cost estimation.

As you have the final cost of the past project after it is completed, you can use the information to get an idea about the cost of the upcoming project.

The condition of the Site:

The condition of the site can change over a short period; heavy rain can cause soil erosions, which can increase the cost of the project.

Also, other factors can increase the complications and the cost of the project such as loses soil, dumped earth, environmental factors, contaminated materials, buried storage tanks, poor soil conditions, and wetlands.

These factors might increase the duration and complications of the project, which will make the project more expensive. Hence, the condition of the construction site should also be considered while estimating the cost of construction.

Market Inflation:

As construction is a complex and prolonged process, it can take anywhere from months to years for a project to complete, during which, the economy may experience changes such as inflation.

Due to this, the cost of various factors of construction can increase such as the cost of labor, materials, etc.

Variation in Labor cost:

The cost of labor for a project can change from time to time due to several factors that are beyond the control of the constructor.

If the duplex cost of construction is considered months in advance from the actual commencement of the project, a revision may be required considering the variation in labor charges.

Duration of the Project:

Project duration is an important factor in the cost of a project. If a project continues for a long period, the cost can increase due to indirect costs such as idle charges, equipment charges, and other factors.

Whereas, on the other hand, if a project is completed quickly that can also be expensive as the direct cost will be high in such a project. You may require more labor and other equipment to facilitate the labor, amongst other things can cause the cost to surge.

Hence, the duration of the project should be considered before estimating the cost of a project.

Design and Planning:

A well-planned design is essential for the success of a project. It acts as a directive for the contractor and other parties’involved in the construction. A well designed Architectural Duplex house plans increase the efficiency of the project while reducing any hurdles.

Poor house design or under designed structure can create problems during the construction causing the cost to increase.

Hence, design and planning are also important factors during cost estimation. These are the twelve considerations that must be kept in mind while estimating the cost of a project. However, we provide a very reliable and effective cost calculator that comes handy, and you must try it for quick cost estimation.
