AI training ROI: the business case your finance team can question

Separate three different claims

Training participation, improved task performance and financial return are different outcomes. A business case should explain how you will move from one to the next rather than treating attendance as evidence of savings.

Use this guide as a planning method for an internal pilot. Its numbers are hypothetical arithmetic, not Experrt customer results or a forecast for your organisation. Ask the budget owner to agree the assumptions and how benefits will be recognised.

Count the full cost

Include the provider fee, participant time, manager support, preparation, tool costs attributable to the pilot and follow-up review. If the team creates practice material or spends time resolving access problems, record that effort too.

Separate one-off setup costs from costs that continue each month. A pilot may look expensive because setup is concentrated at the start. It may also look artificially cheap if you treat internal effort as free. Show both categories so a reviewer can challenge them.

Decide what belongs to training and what belongs to the wider tool rollout. If licences were already purchased, make that assumption explicit rather than silently including or excluding them to improve the result.

Observe the whole task

Measure comparable examples before and after practice. Include preparation, generation, checking and rework. Keep the quality standard consistent. A faster draft is not an improvement if the reviewer spends longer repairing it.

Record the number and type of examples, who participated and which cases were excluded. A small volunteer group may behave differently from a wider rollout. Present the result as an early signal with those limits, not a universal productivity rate.

Use the 30-day adoption plan to structure a test before building a larger spending case.

A hypothetical capacity calculation

Suppose ten people each perform a suitable task eight times per month. In your hypothetical scenario, total effort falls from 30 minutes to 24 minutes per task after checking and rework are included.

That is 10 people × 8 tasks × 6 minutes, or 480 minutes: eight hours of monthly capacity. At an assumed internal value of £40 per hour, the equivalent capacity value would be £320 per month.

Those eight hours are not automatically £320 of cash savings. The organisation needs to explain what happens to the time. It might support additional work, improve responsiveness or reduce overtime. If nothing changes operationally, describe it as potential capacity rather than a realised financial benefit.

Make uncertainty visible

Present a conservative, a central and an optimistic scenario. Change task frequency, the share of suitable tasks and the sustained improvement, rather than pretending one observation is certain to repeat.

Show what would cause the business case to fail. Perhaps review takes longer than expected, the workflow is used infrequently or the tool cost exceeds the benefit. Agree a review date and a stop or redesign decision in advance.

For a financial ROI calculation, use only benefits your organisation agrees are monetisable: approved monetary benefit minus total cost, divided by total cost, for the same period. Keep capacity estimates and non-financial improvements alongside that calculation, clearly labelled.

Add the evidence finance can inspect

Attach the task definition, baseline examples, cost assumptions, quality criteria and named benefit owner. Report adverse outcomes and unsuccessful tasks as well as the useful ones. A transparent case is easier to improve than an impressive percentage with no trail behind it.
