Assumptions & Method

Savings are calculated on variable costs reduced by simulation (placement, travel, consumables) multiplied by the estimated % reduction, plus any staff time savings, avoided repeats, and additional student capacity value.

• Variable cost base per student = placement/support + (optional) travel + consumables.
• Placement-linked savings = variable base × reduction% × students.
• Staff time savings = hours saved × staff rate × students.
• Avoided repeats = repeats avoided × cost per repeat (per year).
• Capacity value = additional students × value per student (per year).
• Annual ROI = (annual savings − annual licence cost) ÷ licence cost.
• Payback (months) = 12 × (licence ÷ annual savings), when savings > 0.
