The Two Calculator Types Explained
1. CD Profit Calculator
This is your flexible "missing value" calculator. Enter any two values and it calculates the third:
- Enter Sale Price + Purchase Price → Calculates Profit
- Enter Sale Price + Profit → Calculates Purchase Price
- Enter Purchase Price + Profit → Calculates Sale Price
Real Example:
You bought a rare CD for $15 and sold it for $45. You remember your profit was $30, but forgot the sale price:
- Purchase Price: $15
- Profit: $30
- Calculator gives: Sale Price = $45
- Profit Margin = (30 ÷ 15) × 100 = 200%
That's an exceptional 200% return on investment!

Step-by-Step Calculation Examples
Example 1: Single CD Resale
Scenario: You found a rare 1990s CD at a thrift store for $5 and sold it online for $35.
- Purchase Price: $5
- Sale Price: $35
- Profit: $35 - $5 = $30
- Profit Margin: ($30 ÷ $5) × 100 = 600%
- ROI: 600% (same as profit margin for single items)
Result: Exceptional profit! You made 6 times your investment.
Example 2: Bulk Purchase with Different Profit
Scenario: You bought 20 CDs in a bundle for $100 total ($5 each). You plan to sell them individually for an average of $12 each.
- Total Purchase Price: $100
- Total Sale Price: 20 × $12 = $240
- Total Profit: $240 - $100 = $140
- Profit Per CD: $12 - $5 = $7
- Profit Margin: ($7 ÷ $5) × 100 = 140% per CD
- Total ROI: ($140 ÷ $100) × 100 = 140%
Result: Excellent bulk opportunity! 140% return on your investment.
