Formula
Total cost = fixed cost + other cost + (active learners × variable cost)
Cost per learner = total cost ÷ active learners
Target scale = (fixed + other) ÷ (target cost − variable cost)
What the result means
Use the result as a planning baseline for the digital assessment program. It is only as reliable as the period, population, and operational assumptions entered.
Planning estimate only. Validate material decisions against actual system reports, contracts, staffing data, and program requirements.
