HR Software ROI: How to Justify Investment in a New HR System

‍

HR software ROI must answer a fairly specific question: will the new system generate enough measurable value to make the investment worthwhile within the organisation? Calculating this is not complicated in itself. However, it is far more difficult to accurately determine how much current HR processes cost today, what the total investment will be, and which changes can actually be observed after the system goes live. Let’s explore which cost and benefit categories are worth including, how to calculate the return on investment, and what evidence is needed to ensure the HR software business case is acceptable to both the HR and Finance teams.

Quick Take

• Return on investment should be calculated based on your organisation’s own data, not generic market percentages.
• Current HR costs also include the time managers and employees spend on HR tasks, the cost of correcting errors and the cost of maintaining disconnected systems.
• Licence and implementation costs represent an investment, but not yet the value that will be received in return.
• A reliable HR software business case requires a baseline, sound assumptions and a consistent timeframe for comparing costs and benefits.
• HR and Finance should agree, before making a decision, on what will be measured and how after go-live.

How much does the organisation’s current HR work cost?

The cost of the new system is fairly specific and is set out in the proposal. In contrast, estimating the cost of current processes is somewhat more complex, as it is spread across working hours, error fixes and the maintenance of various tools. When calculating the ROI of HR software, start with the current-state HR operating costs, rather than the promises of the future system. This baseline may include the following costs:

• administrative time costs: data entry, reporting and verification;
• employee and manager time: enquiries, approvals and searching for information;
• cost of errors and rework: correcting inaccuracies and re-coordination;
• cost of fragmented HR processes: licences, integration and the maintenance of multiple data sources.

If a significant proportion consists of repetitive administrative tasks, you should also consider  where HR workflow automation can reduce the amount of manual work.

What is the investment per employee?

To make it easier to compare your total proposal cost with your current HR operating costs and potential benefits, calculate it per employee. Jigsaw Cloud has provided the following indicative five-year scenarios for organisations of different sizes:

For a 400-employee organisation, the investment would amount to approximately £2.46 per employee per week. This figure alone does not indicate whether the investment is high or low. To assess this, it must be compared with the value the system could generate: time saved, reduced costs due to errors and rework, or the costs of systems that would otherwise be abandoned. It is precisely this comparison that forms the basis of HR software ROI.

The total investment must include licence costs, implementation costs and internal team time. The scenarios presented are based on the SmartStart pre-configured SAP SuccessFactors model, in which the scope of implementation and the commercial model are defined in advance. This gives the business case a clearer investment figure, which can then be compared with measurable benefit assumptions.

How do you calculate HR software ROI?

HR software ROI indicates the financial value an organisation receives in comparison to the amount invested. A negative ROI means that the benefits have not yet covered the investment, 0% means they have equalled it, and a positive ROI means they have exceeded it. However, there is no universal ‘good’ percentage, so the result must be assessed in conjunction with the chosen time period, the payback period, and the reliability of the assumptions used in the calculation.

HR software ROI (%) = (measurable benefits – total investment) / total investment × 100

Benefits may include the value of time saved, reduced costs of errors and the costs of systems that have been phased out.

Total investment should include licences, implementation, support and the time spent by the in-house team. Both figures are calculated over the same period.

To verify the return on investment after the system goes live, record the baseline situation before implementation: the time spent on HR tasks, the costs of errors and rework, and the costs of current systems. After go-live, compare the same metrics – the change in these figures will show the actual value created.

Which benefits of HR software can be measured?

To assess HR software benefits, each expected benefit must be linked to a specific metric, for example:

• Expected cost and scope. Did the actual budget and work carried out match the agreement?
• Reduced operational complexity. By how much has the time spent on specific administrative tasks been reduced?
• A unified HR data foundation. How many separate tools, contracts or data transfer steps are no longer required?
• Faster time to value. When did the organisation start using the first operational process?
• The ability to scale without changing the system. As the organisation grows in complexity, can HR processes be expanded on the same platform?

HR automation benefits and HR software cost savings may arise in these areas, but they should not be regarded as a guaranteed return in advance. Only those benefits for which the organisation has a baseline figure and can subsequently measure the actual change should be included in the ROI calculation.

What might such value look like in practice? The experience of one of Jigsaw Cloud’s clients provides an illustration. In the Cleanova case study, you can find out more about how centralised data and more consistent processes helped support the operations of a growing organisation. This was not a SmartStart project and does not validate the pricing scenarios in this article; it is included only as an example of how measurable value may appear in practice.

When is an HR software business case strong enough?

A reliable business case for HR software should not promise the highest possible return. On the contrary, it must demonstrate how a current problem is transformed into measurable financial value. For each benefit, there should be a clear baseline metric, the expected change, the method of calculation, and the timeframe within which the result should be achieved.

It is particularly important to distinguish between direct savings and the time freed up for the team. If automation frees up time but does not reduce overtime, external services or payroll costs, it should be recorded as additional capacity rather than a direct saving. Its value can instead be demonstrated by showing which previously delayed tasks the team will now be able to complete.

Employee turnover costs are excluded here because Jigsaw Cloud has not provided a verified typical value or evidence that any change could be attributed directly to the HR system.

The final calculation should be checked against three scenarios:

• probable, based on the most realistic ROI assumptions;
• a conservative one, in which the benefits materialise more slowly or are smaller;
• a break-even scenario, showing the minimum result required for the investment to pay for itself.

This business-case sensitivity analysis makes it possible to assess whether the decision remains justified even in the event of a more modest outcome. If the answer is yes, the ROI of HR software is based not on a single optimistic projection, but on verifiable logic: we know the current costs, the total investment, the expected benefits and how we will measure them after go-live. It is precisely this ROI evidence that provides HR and Finance with a common basis for decision-making.

FAQ

How to build a business case for new HR software?

Firstly, identify which current HR processes need to be changed and how much they cost the organisation. Then calculate the total investment, select measurable benefit categories and define the overall evaluation period. For each projected benefit, specify the data source, calculation method and assumptions used. Include both a likely and a conservative scenario, and set out how the results will be measured after go-live.

What should be included in an HR software ROI calculation?

In an HR software ROI calculation, measurable benefits are compared with the total investment over the same period. Benefits may include direct cost reductions, the value of time saved through process automation, and the costs of systems that are no longer required. The investment should include licences, implementation, integrations, data migration, support and the time spent by the internal team.

Which HR costs should be measured before implementing a new system?

Before implementation, measure the costs of current licences and support, the time spent on HR administration, the time spent by staff and managers on HR tasks, error correction, repetitive work and manual data transfer. Also include external services related to the selected processes. Collect data over a representative period so that you can repeat the same measurement after implementation.

Which benefits of HR software can be measured reliably?

The most reliable way to measure the benefits of HR software is to have a baseline figure recorded prior to implementation. These may include the time allocated to a process, the number of errors and corrections, the duration of the process, the costs of abandoned systems, or the level of system usage. The same definition of the indicator and calculation method must be applied both before and after implementation.

Which assumptions in an HR software business case need evidence?

Assumptions regarding the anticipated level of system usage, time saved, the financial value attributed to that time, time to value, and the systems or services to be phased out must be substantiated. Sources may include internal process data, payroll information, the implementation proposal, or a documented market indicator. If precise data is not available, use a range of possible values rather than a single fixed estimate.

What should HR and Finance agree before approving a new HR system?

HR and Finance should agree on the assessment period, the costs to be included in the investment, and the evaluation of different types of benefits. It is also necessary to agree on baseline metrics, ROI assumptions, the required rate of return or payback period, and both optimistic and conservative scenarios. Even before the project is approved, it should be clear who will collect the data after go-live and when the results will be reviewed.

Can your investment in an HR system be justified with figures?

An HR software business case should not be based solely on an attractive percentage figure. Jigsaw Cloud helps to assess the cost inputs and implementation scope of SmartStart, whilst the organisation’s data reveals the other side of the equation – what value can reasonably be expected.
