Discount Calculator
Use this discount calculator to find the sale price after a percentage discount and see exactly how much you save. You can also apply tax after the discount to estimate the final amount paid at checkout. It is useful for shopping, seasonal sales, ecommerce pricing, coupons and business offers where you want to compare several discount scenarios quickly.
Frequently Asked Questions
Discount Amount = Original Price × (Discount% / 100). Then Sale Price = Original Price − Discount Amount. Example: 20% off €100 = €20 discount → €80 sale price.
For successive discounts (e.g. 20% then 10%), apply them sequentially — not by adding percentages. A 20% + 10% discount is NOT 30% off; it's 28% off. Use this calculator twice for sequential discounts.
In many common pricing scenarios, tax is applied after the discount, which is exactly how this calculator works. However, tax rules can vary by country and business context, so use your local rules for invoicing.
How this calculator works
Formula explanation
**Formulas:** Discount Amount = Original Price × (Discount% / 100) | Sale Price = Original − Discount Amount | Final Price (with tax) = Sale Price × (1 + Tax%/100)
