Most L&D teams measure training ROI by completion rates and satisfaction scores. Both are vanity metrics. Completion tells you a video was watched. Satisfaction tells you the content was enjoyable. Neither tells you whether your organisation can do anything it couldn't do before.
The ROI Framework We Use
Real training ROI measures four dimensions: knowledge retention at 30, 60, and 90 days; skill application rate (are learners using new skills?); business outcome linkage (did AI projects succeed that required trained skills?); and cost comparison versus alternative delivery.
Retention: Where Most Training Fails
Without reinforcement, learners forget 50% of new information within 24 hours and 70% within a week. Adaptive learning counters this with spaced repetition — surfacing concepts at the optimal interval for each individual learner based on their retention patterns.
“Astralearnia Institute programmes achieve 71% knowledge retention at 90 days, versus 23% for standard e-learning and 18% for classroom training.
The Cost Calculation
Against our previous classroom training provider: $340 per learner per day with 18% retention at 90 days. Astralearnia Institute: $12 per learner per month with 71% retention. For a 500-person upskilling programme, that's a $1.2M saving with dramatically better outcomes.
