Price Comparison Calculator — 公式
## How to Compare Product Prices
Compute the unit price for each product, then see which is lower. The percentage difference tells you how much more expensive the pricier option is.
### Formula
**Unit Price = Total Price / Quantity**
**Difference % = |Unit A - Unit B| / max(Unit A, Unit B) x 100**

计算示例
Product A: 6-pack for $3.99 vs Product B: 10-pack for $5.49.
- Product A unit price = $3.99 / 6 = $0.6650
- Product B unit price = $5.49 / 10 = $0.5490
- Product B is cheaper per unit
- Difference = |$0.6650 - $0.5490| / $0.6650 x 100 = 17.4%
