How to use

Use this discount calculator to quickly figure out how much you save during a sale or promotion. Simply input the 'Original Price' of the item or service you wish to buy. Then, enter the 'Discount Percentage' being offered (for example, type 20 for a 20% off sale).

The tool will instantly calculate both the 'Amount Saved' and the 'Final Price' you need to pay at checkout. This helps you verify that you are getting the correct deal before making a purchase.

Retailers and business owners can also use this calculator in reverse. By testing different discount percentages, you can see exactly how it affects the final selling price and profit margins before launching a new marketing campaign.

Examples

1,000,000 ₫ at 20% off → 800,000 ₫

  • Original Price:1,000,000
  • Discount Percentage:20

Result

  • Final Price:800,000
  • amount_saved:200,000

A 1,000,000 VND item at a 20% discount means you save 200,000 VND. Your final price to pay is exactly 800,000 VND.

500,000 ₫ at 30% off → 350,000 ₫

  • Original Price:500,000
  • Discount Percentage:30

Result

  • You Save:150,000
  • Final Price:350,000
  • Discount Amount:150,000

A 30% discount on a 500,000₫ item saves 150,000₫, bringing the final price to 350,000₫. For retailers, a 30% discount typically requires at least a 45%+ gross margin to remain profitable — check your cost before running deep promotions.

Frequently Asked Questions

How is the discount amount calculated?

To find out exactly how much money you will keep in your pocket, you can calculate the discount amount using this simple formula: Original Price multiplied by the Discount Percentage, then divided by 100. For instance, if you purchase a 1,000,000 ₫ item that is currently 20% off, your math is 1,000,000 × 20 ÷ 100, which results in a generous 200,000 ₫ discount.

How is the final price calculated?

The Final Price is simply your Original Price minus the Discount Amount. For example, if you buy a 1,000,000 ₫ item and receive a 200,000 ₫ discount, your calculation is 1,000,000 − 200,000. This brings your final out-of-pocket cost down to exactly 800,000 ₫.

Can I use this for sale prices in stores?

Yes, this tool is perfect for shopping. Simply enter the original pre-sale price and the advertised discount percentage. The calculator will immediately show you the exact amount of money you are saving, as well as the final price you will have to pay at the checkout counter.

How do I calculate multiple stacked discounts?

When dealing with stacked discounts, you cannot simply add the percentages together. If an item is initially 20% off and you also have an extra 10% coupon, you must calculate the 20% discount first. Once you have that new subtotal, you then apply the 10% discount to the newly reduced price to find your true final cost.
