About the tool

What it does and what to expect

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%.

How it works

A simple, local workflow

  1. 1Enter the original price, the main discount percentage, and an optional additional discount.
  2. 2Each discount is applied to the remaining price in sequence.
  3. 3The result shows the final sale price, total money saved, and effective combined discount.

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.
