Build vs. Buy Calculator: A Comprehensive Guide

About

The decision to build a solution in-house or buy an off-the-shelf product is one of the most critical choices faced by businesses today. The Build vs. Buy Calculator serves as a crucial tool in this decision-making process. It allows organizations to evaluate the costs, benefits, and strategic implications of both options effectively. With the advent of advanced analytics and increasing market competition, understanding which approach aligns best with your company’s goals becomes indispensable.

In this guide, we will walk you through how to use the Build vs. Buy Calculator, including its formula, example calculations, limitations, and its advantages. You’ll also find tips for managing your decision-making process, common use cases, frequently asked questions, and more.

How to Use

Using the Build vs. Buy Calculator is straightforward. To start, you’ll need to gather key information about both options:

• Cost Estimates: Determine the projected costs for both building and buying the solution.
• Timeframe: Assess the timeline for each option.
• Resource Availability: Evaluate your team’s capabilities and availability.
• Maintenance Costs: Factor in ongoing maintenance and support costs.
• Scalability Needs: Consider future growth and scalability requirements.

With this information in hand, enter the data into the calculator, which will help provide a comparative analysis to aid in your decision.

Formula

The basic formula to compare the total costs for building and buying solutions encompasses several factors:

• Total Cost of Ownership (TCO): TCO = Initial Costs + Maintenance Costs + Upgrade Costs + Opportunity Costs
• Time of Development: Consider the time taken to build versus the time to implement the purchase.
• Intangible Benefits: Weigh in factors such as customer satisfaction, employee morale, and flexibility.

By applying these formulas to both scenarios, you can obtain a clearer picture of which option is more financially sound and strategically viable.

Example Calculation

Let’s consider an example where a company is deciding between building an internal customer relationship management (CRM) system or purchasing an existing one:

• Building Internal CRM:
  • Initial Costs: $50,000
  • Annual Maintenance: $10,000
  • Upgrade Costs Over 5 Years: $15,000
  • Opportunity Costs: $20,000

  Total TCO = $50,000 + ($10,000 x 5) + $15,000 + $20,000 = $125,000

• Purchasing CRM:
  • Initial Costs: $30,000
  • Annual Maintenance: $5,000
  • Upgrade Costs Over 5 Years: $5,000

  Total TCO = $30,000 + ($5,000 x 5) + $5,000 = $60,000

From this example, it’s clear that purchasing the CRM system is financially more advantageous.

Limitations

While the Build vs. Buy Calculator is an invaluable tool, it does come with limitations:

• Subjectivity: The values entered into the calculator may vary based on personal or organizational biases.
• Dynamic Market Conditions: The ever-changing technology landscape can affect both the cost and effectiveness of solutions.
• Overlooked Intangible Costs: Soft costs such as team morale and customer satisfaction can be difficult to quantify but may influence outcomes significantly.

To effectively manage the build vs. buy decision:

• Conduct a detailed capabilities assessment of your internal team.
• Engage stakeholders across departments to gather diverse perspectives.
• Stay updated on market trends and emerging technologies that impact costs and benefits.
• Consider a phased implementation strategy if you choose to build.
