If you are considering investing in an ERP system, you need to know the total cost of ownership (TCO) before making a decision. TCO is the sum of all direct and indirect costs associated with acquiring, implementing, maintaining, and upgrading an ERP system over its lifetime. In this article, we will explain how to calculate the TCO of an ERP system and what factors to consider.
The first step to calculate the TCO of an ERP system is to identify and estimate the different types of costs involved. These can be categorized into four main groups: software, hardware, services, and operational. Software costs include the license fees, subscription fees, or cloud fees for the ERP software and any additional modules or integrations. Hardware costs include the servers, storage, network, and devices required to run the ERP system. Services costs include the consulting, training, customization, implementation, support, and maintenance fees for the ERP system. Operational costs include the staff salaries, overheads, utilities, and other expenses related to running the ERP system.
It's essential to recognise that these costs can vary widely based on the specific requirements of your business, the vendor chosen, and the industry you're in. Accurate forecasting requires a deep understanding of your unique needs.

Note that the question is about TCO ownership of ERP. Divide into three sections; adoption, production, replacement. Drill into estimates in each area and add up for TCO.
The second step to calculate the TCO of an ERP system is to choose a method to estimate the costs over time. There are different methods to do this, but two common ones are the net present value (NPV) method and the payback period method. The NPV method calculates the present value of the future cash flows from the ERP system, minus the initial investment. The payback period method calculates how long it takes to recover the initial investment from the ERP system's benefits. Both methods require assumptions about the discount rate, the inflation rate, the lifespan, and the benefits of the ERP system.
The method chosen should align with your business's strategic goals and risk tolerance. Whether focusing on immediate payback or long-term value, aligning with financial policies and targets is crucial.
The third step to calculate the TCO of an ERP system is to quantify the benefits that the ERP system will bring to your business. These can be categorized into two main groups: financial and non-financial. Financial benefits are the measurable savings or revenues that result from the ERP system, such as reduced inventory costs, increased sales, improved cash flow, or enhanced productivity. Non-financial benefits are the intangible improvements that result from the ERP system, such as better customer service, higher quality, more innovation, or greater compliance.
Beyond numerical benefits, considering the cultural and organisational changes that an ERP system can bring might be vital. An alignment with your company's mission and long-term strategies can elevate an ERP system from a cost-saving tool to a core business asset.
The fourth step to calculate the TCO of an ERP system is to use a tool to compare different ERP systems and options. There are various tools available online or from vendors that can help you calculate and compare the TCO of different ERP systems. These tools can help you input your data, adjust your assumptions, and generate reports and charts that show the TCO breakdown and comparison. However, you should be careful to use these tools with caution and verify their accuracy and reliability.
While online tools can be beneficial, partnering with a skilled consultant who understands your industry can provide customised insights. Independent analysis, rather than vendor-provided tools, can often provide a more objective perspective.
The fifth step to calculate the TCO of an ERP system is to follow some best practices to ensure that you get the most accurate and realistic results. These include including all relevant costs and benefits in your calculation, using realistic and conservative assumptions and scenarios, updating your calculation regularly, comparing the TCO of different ERP systems and options, and considering the value and risks of the ERP system. Doing so will help you make a more informed decision about which ERP system is best for your business.
Maintaining open lines of communication with stakeholders throughout the process ensures that TCO calculations reflect the true complexity of your business needs. Regular updates foster alignment and mitigate surprises down the road.
The final step to calculate the TCO of an ERP system is to draw a conclusion based on your analysis and comparison. The TCO of an ERP system is not a fixed or definitive number, but a range or an estimate that depends on many factors and assumptions. Therefore, you should use the TCO as a guide, not a rule, to help you make an informed and strategic decision about your ERP system investment. The TCO of an ERP system is not the only criterion to consider, but one of the many aspects that affect your business performance and goals.
Your ERP decision is not just a financial one; it's a strategic business decision. Balancing the TCO with qualitative factors such as vendor reliability, scalability, and alignment with business goals ensures a holistic approach.
