TI 84 Plus CE Online Value Calculation Formula and Mathematical Explanation

Our TI 84 Plus CE calculator online value tool uses a composite score to help you weigh various factors. The core idea is to quantify the “value” of an online solution by considering its cost-effectiveness, time-saving potential, and how well it aligns with your personal preferences for features like portability and physical interaction.

The “Online Value Score” is calculated using the following steps:

1. Calculate Total Physical Calculator Cost (TPCC): This is simply the one-time purchase cost of the physical calculator.
   TPCC = Physical_Cost
2. Calculate Total Online Subscription Cost (TOSC): This accounts for the recurring cost of an online emulator over your planned years of use.
   TOSC = Monthly_Online_Cost × 12 × Years_Of_Use
3. Calculate Total Estimated Time Saved (TETS): This quantifies the efficiency gains from using an online tool.
   TETS = (Time_Saved_Weekly × 52 × Years_Of_Use) / 60 (in hours)
4. Calculate Cost Savings Factor (CSF): This measures how much cheaper the online option is relative to the physical one.
   CSF = (TPCC - TOSC) / TPCC (if TPCC > 0, otherwise 0)
5. Calculate Time Savings Factor (TSF): This normalizes the time saved into a score. We assume a maximum potential time saving for normalization (e.g., 10 hours/week * 52 weeks * years).
   TSF = TETS / (10 × 52 × Years_Of_Use) (normalized to a max of 1 if 10 hours/week saved)
6. Calculate Portability Preference Factor (PPF): Since online versions are less physically portable, a lower importance of portability increases the online value.
   PPF = (6 - Portability_Importance) / 5 (scales 1-5 importance to 1-0.2 for online value)
7. Calculate Physical Buttons Preference Factor (PBPF): Similarly, online versions lack physical buttons, so a lower importance of physical buttons increases the online value.
   PBPF = (6 - Physical_Buttons_Importance) / 5 (scales 1-5 importance to 1-0.2 for online value)
8. Calculate Online Value Score (OVS): This is a weighted sum of the factors. The weights can be adjusted based on perceived importance.
   OVS = (CSF × 40) + (TSF × 30) + (PPF × 15) + (PBPF × 15)
   The score is then capped at 100 and floored at 0.
