How to Estimate Cost of Custom Software Development?

As an entrepreneur, before you start any software development project, you will need to identify the project’s cost. In the end, it’s all about ROI (Return on Investment) in any business, and by estimating the cost of your custom software project development, you can generate a great ROI. Estimating the cost of a software project and staying within the budget is difficult, even for top software development companies, where the requirements are not clear and there are external factors that play a major role in defining them. Through this blog, we will ease this difficulty for you as decision-maker.

Estimating the Cost of Custom Software Development Based on Size and Type

Here are the two main ways to estimate the cost of custom software development.

Estimating Custom Software Development Costs Based on the Size of the Software

The size of the software is one of the biggest determinants of the cost of the custom software you want to build. As a thumb rule, the larger the software, the higher it will cost you. We have mentioned below a quick cost estimate based on the size of the software.

A small-sized software will cost around $15,000- $55,000 to build. It usually takes around 1-3 months to build such software, and a small skilled software development team is sufficient to build a small size software.

A medium-sized software build for mid-sized businesses can cost you $55,000-$450,000. A mid-sized software development team is required to build a medium-sized software, and it takes around 6-9 months on average to build a mid-sized software.

A large-sized software with multiple integrations intended to be used by millions of users speaking multiple languages and in different locations across the globe can cost anywhere in the pricing range of $550,000-$1,000,000. A large software development team will take around 1-2 years to deliver a large-sized software.

Estimating Custom Software Development Costs Based on the Type of the Software

There is a wide variety of software being developed today. The type of software you want to build has an overbearing effect on the development cost. Here is a brief overview of the software development price according to the type of software built.

  • SaaS product: $40,000 to $180,000
  • eCommerce software: $12,000 to $530,000
  • CMS software development: $8,000 to $52,000
  • CRM software development: $15,000 to $53,000

The crux of the matter is that the cost of developing a software depends on the features you want in your software, the size of the software and the level of customization required while developing the software.

Factors Affecting the Cost of Custom Software Development

By knowing the factors that affect your custom software development cost, you can get more clarity on their impact on the development cost of custom software. We will now see the most critical factors that impact the cost of your software development project.

Size of Software

The size of the software is one of the most significant factors that will affect the custom software development cost. As the size of the software increases, so does the expenses. The size of the software is interlinked with the number of intended users and the complexity of the project.

Software Development Approach

If you choose to work with an ideal software development company with a fast and reliable development approach, then the cost of your project will be less. Agile is one of the most popular software development approaches today. Agile helps reduce the number of hours spent on the project, thus helping to reduce the cost of software development.

Complexity of Software

Software is said to be more complex when it contains too many features and consumes a lot of processing power. A lot of experienced software developer hours need to be invested in building complex software, which increases the cost of the software development process.

Software Design Requirements

It is always a good idea to build an attractive design for your software, but an attractive design also comes with extra expenditure. More money needs to be spent on building elegant and attractive designs for your software as you need to invest more hours in building such designs.


Every software requires some third-party integrations to function according to the user’s requirements. As a rule of thumb, the more third-party systems you integrate into your software, the more the cost of developing the software will be. The software development price rises due to the compatibility issues that invariably arise due to integration.

Hiring Models for Software Development

The cost of custom software development depends greatly on the team you select to develop your custom software. Generally, the following are the basic team models which are used to hire finest software developers.

Hire Freelancers for Software Development

You can choose to hire freelancers to build your custom software. Hiring freelance software developers often proves to be a cost-effective option. The problem, however, with hiring freelance developers is that they can turn their backs on you at any time, leaving you and your software development project in trouble.

Hire In-house team for Software Development

As the name suggests in the in-house team model, you will need to hire software developers in-house to build your custom software. The in-house team model proves to be one of the costliest options as you will need to invest in office infrastructure and give salaries and other benefits to your in-house software developers.

Hire a Professional Company to Outsource Software Development

Outsourcing your custom software development project often proves to be the best option. Not only is it cost-effective compared to hurting in-house developers, but outsourcing is also more efficient and reliable than hiring freelancers. Outsource your custom software development to best software development company and reduce the software development cost.

Location of the team

The location of the software development team also has an overbearing effect on the cost of custom software development solutions. When you choose to outsource your work to dedicated software developers located in Western Europe and North America, the cost to develop software will be higher than remote software developers residing in countries like India. The following is the per hour cost of hiring developers in various regions.

  • U.S.A- $90-$140
  • U.K.-$60-$90
  • India-$24-$45

Size of the Software Development Team

The software development cost is directly proportional to the size of the team. In turn, the size of the team depends on the complexity of the project. For instance, if you want to build software that can run on multiple operating systems, has separate dashboards for different users, and has multiple new features, you will need to deploy a large software development team.

A small team would be sufficient if you want a simple customized software development solution with no complex features. Depending on the size of the team required, you will have to allocate your custom software development budget.

Engagement Models for Software Development

The engagement model of software development also plays an important role in deciding the final cost of software development. The following are the major engagement models used today to develop custom software.

Fixed-price model

In the fixed-price model, the scope of the project and the cost of the project is fixed. The fixed-price model works best when you have well-defined software project requirements, as, without a fixed scope, it is difficult to estimate the cost of the software development project.

The fixed-price model lets you monitor the project’s progress and release the payment accordingly. The fixed-price model for software development thus helps you to minimize the project risk. If there are significant changes in the project’s initial scope, then both parties need to approve the changes to revise the price of software development.

Time and material model

In most cases, businesses choose to go with the time and material model for their software development needs. This is because the scope of the custom software is rarely defined and keeps on evolving with the dynamic needs of the market.

Normally after studying the project’s scope, the vendor fixes an hourly rate for billing. The number of hours taken to build a project is then multiplied by the hourly rate, and the final software development cost is calculated.

One of the major advantages of the time and material model is that it provides flexibility. If there are any major changes in the scope of software development project, the software development agency needs to quote the extra number of hours that will be required to inculcate these changes.

Approach to Software Development Cost Estimation

Top custom software development companies utilize certain methods for estimating the cost of custom software development. Basic knowledge of these budget estimation methods will help you assess whether the cost estimate you have received as the proposal is appropriate. The following are the various approaches for cost estimation.

Bottom-up estimation

The bottom-up cost estimation approach breaks down the cost of software development into small components. The components of the entire project are subdivided into several groups. These groups are then again divided into sprints. It is easy for the cost-effective software development firm to decode the cost of each sprint. The cost of individual sprints is then summed up to identify the total cost of the software development.


The leading software development company segments software into several parts in the analogous cost estimation method. For large projects, the dedicated software developers launch the minimum viable product first and then estimate the cost of the other project components based on the price of the minimum viable product.

The analogous cost estimation relies on the data acquired from previous projects and historical data. This is why the analogous price estimation method is not considered a very accurate costing method, as it provides a rough cost estimate based on previous data and there are chances that the actual budget shoots way beyond than what was proposed in the proposal.


You can hire best software developers who can benefit your business and provide certain methods for estimating the cost of custom software development.
