Discount Calculator
Calculate the final discounted price from the original price and discount percentage. See how much you save and the actual price you pay after discount.
How to Use
1. Enter original price
2. Select discount method (rate or amount)
3. Enter discount value and click Add button
4. Multiple discounts are applied sequentially (stacked discounts)
Example: 100,000 with 20% off then 10% off = 80,000 → 72,000
Formula and decision logic
A discount lowers the original price either by a percentage or by a fixed amount, and stacked discounts apply sequentially instead of all at once.
Final price = original × (1 - discount rate)
Stacked discount = previous result × (1 - next rate)

How to read the result
- A second discount usually saves less than you expect because it applies to the already reduced price.
- Comparing the final price is more reliable than comparing discount labels alone.
Common input mistakes
- Adding multiple percentage discounts together instead of applying them one by one.
- Comparing fixed-amount promotions and percentage promotions without checking the same base price.
