Formula and Mathematical Explanation
The calculation is based on a simple cost-benefit analysis. We determine the net value by subtracting the total costs from the total benefits (estimated value).
Step-by-Step Derivation:
- Total Upfront Cost = Calculator Purchase Price + Accessories Cost
- Cost Per Year = Total Upfront Cost / Expected Years of Use
- Total Estimated Value = Estimated Annual Academic Value × Expected Years of Use
- Net Value = Total Estimated Value – Total Upfront Cost
