Common pitfalls

  • Fees, penalties, inflation, and local rules can make real outcomes differ from simple formulas.
  • Treat results as guidance, not financial, tax, legal, or investment advice.

Frequently asked questions

How is the discounted price calculated?

Discounted price equals original price minus (original price times discount percent). The tool also shows the amount you save.

How do I stack two discounts?

Stacked discounts apply one after another, not added together. A 20% then 10% off is 0.8 times 0.9, which is 28% off, not 30%.

How do I find the original price from a sale price?

Divide the sale price by (1 minus the discount as a decimal). A 25 percent off item priced 75 had an original price of 100.

Does it handle tax?

The core calculation is pre-tax. Apply tax to the discounted price afterward, since most regions tax the post-discount amount.

What is the difference between percent off and a fixed amount off?

Percent off scales with price, while a fixed amount subtracts the same value regardless of price. On cheap items a fixed amount can be the bigger saving.

Is any data uploaded?

No. All calculations run locally in your browser.
