Campaign and Multi-Discount Calculator
In some cases, a product may have both a general discount and be included in a second campaign like "additional 10% off at checkout". This calculation allows you to find the actual rate and final price of tiered discounts applied consecutively.
Key Terms
- Original Price: The list price before any discount is applied.
- Tiered Discount: Instead of directly adding discounts (e.g., instead of 20% + 10% = 30%), it is the application of the second one over the remaining amount after the first one is applied.
- Effective Discount Rate: The percentage-based equivalent of the total net discount made from the product's original price.
How it is Calculated?
Suppose for a 100 TL product there is a 20% list discount and an additional 10% discount at checkout:
- After First Discount: 100 * 0.80 = 80 TL
- After Second Discount: 80 * 0.90 = 72 TL
- Total Savings: 100 - 72 = 28 TL
- Actual (Effective) Discount: 28%
As you can see, discounts are not directly added (it doesn't become 30%), they are calculated in stages.
