Check sale prices and stacked discounts
Shoppers and retailers use a discount calculator to see the final price and actual savings before checkout or promotion approval. A second discount is applied sequentially, which is different from simply adding the two percentages.
A worked example
An item priced at 5,000 with 20% off costs 4,000. Add a further 10% discount and the final price becomes 3,600—an effective discount of 28%, not 30%.

FAQs
Common questions
How do I calculate a discounted price?
Multiply the original price by one minus the discount rate. A 20% discount means multiplying by 0.80.
Why are 20% and 10% discounts not equal to 30% off?
The second discount applies to the already-reduced price, so the combined reduction is 1 − (0.80 × 0.90) = 28%.
Does this include sales tax?
No. The result is the price after discounts but before any tax, shipping, or other checkout charges.
