Calculator on iPhone 7 Formula and Mathematical Explanation

Our calculator on iPhone 7 uses several key metrics to derive the overall Viability Score. Understanding these formulas helps you interpret the results more effectively.

Step-by-Step Derivation:

1. Device Age (Years): This is the time elapsed since the original purchase date.
   
   Device Age = (Current Date - Original Purchase Date) / (Milliseconds in a Year)
2. Depreciation Percentage: This measures how much value the iPhone 7 has lost relative to its original price.
   
   Depreciation % = ((Original Purchase Price - Current Resale Value) / Original Purchase Price) * 100
3. Annualized Cost of Ownership: This estimates the average cost per year you’ve effectively paid to own the device, considering its initial cost, current value, and expected repairs.
   
   Annualized Cost = (Original Purchase Price - Current Resale Value + Expected Repair Cost) / Device Age
4. Performance Gap: This quantifies the difference between your desired performance and the device’s current estimated performance.
   
   Performance Gap = Desired Minimum Performance Score - Current Performance Score
5. Overall Viability Score: This is a weighted score starting at 100, with deductions based on the above factors.
   • Initial Score: 100
   • Deductions for Age: (Device Age – 3) * 5 (if Device Age > 3)
   • Deductions for Depreciation: (Depreciation % – 50) * 0.1 (if Depreciation % > 50)
   • Deductions for Annualized Cost: (Annualized Cost – 50) * 0.5 (if Annualized Cost > 50)
   • Deductions for Performance Gap: Performance Gap * 1 (if Performance Gap > 0)
   • The final score is capped between 0 and 100.

Interpretation: Despite being well-maintained, the age and high depreciation significantly impact the score. The annualized cost is also relatively high for an older device. While a new battery might improve performance, the overall viability suggests that Sarah might get more value by upgrading, especially if her desired performance is 75 and the current is 65.

Example 2: The Budget-Friendly, Recently Acquired iPhone 7

Mark bought a used iPhone 7 a year ago for a very low price. He’s happy with it but wants to know its long-term viability.

• Original Purchase Date: 2023-03-01 (when Mark acquired it, treating this as his “original” purchase for his ownership period)
• Original Purchase Price: 80 USD (what Mark paid)
• Estimated Current Resale Value: 50 USD
• Expected Repair Cost: 0 USD (no issues expected soon)
• Desired Minimum Performance Score: 60
• Current Performance Score: 55

Calculator Output:

• Device Age: ~1.5 years (since Mark’s purchase)
• Depreciation Percentage: ~37.5%
• Annualized Cost of Ownership: ~20 USD/year
• Overall iPhone 7 Viability Score: ~70
• Recommendation: Good Value, Still Viable.

Interpretation: For Mark, who acquired the device cheaply, the annualized cost of ownership is very low. Although the performance gap exists, it’s not as critical given his lower desired performance. The calculator suggests his iPhone 7 is still a good value for him, especially considering his initial investment. This highlights how the “original purchase date” and “price” can be adapted to reflect the user’s personal ownership period and cost.
