What is Discount Calculator?
A discount calculator instantly tells you how much you save and what you actually pay when an item is on sale. Enter the original price and the discount percentage, and it computes both the amount saved and the final price. You can also add a tax percentage to see the true checkout total.
It takes the guesswork out of sale shopping and helps you compare offers at a glance.

Benefits & Use Cases
Shoppers verify that advertised deals are as good as they look, budget-conscious buyers plan purchases, and retailers price items during sales. Knowing the real final cost, including tax, prevents surprises at the register.
All calculations happen in your browser, so it is fast and works even while you are offline in a store.
The Discount Calculator is completely free, needs no sign-up or installation, and runs entirely in your browser — nothing you enter is uploaded to a server, so your data stays private. It works on desktop, tablet and mobile, in light or dark mode.
Tips & Best Practices
Enter the original price and the discount percentage to see both what you save and the final price. For stacked offers ("extra 10% off sale items"), apply the first discount, then use its result as the price for the second — discounts multiply, they do not simply add. Add a tax rate to see the real checkout total, since tax is applied after the discount.
To work out any other percentage, use the Percentage Calculator; add sales tax or GST separately with the GST / Tax Calculator.
FAQ about Discount Calculator
How is the discount amount calculated?
It multiplies the original price by the discount percentage. For example, 25% off 1200 saves 300, leaving a sale price of 900.
Is tax applied before or after the discount?
Tax is applied after the discount, which matches how most shops calculate the final price you pay at checkout.
Can I use it for any currency?
Yes. The calculator only works with numbers, so the results apply to any currency you are shopping in.
Does it handle stacked discounts?
It applies a single percentage. For stacked offers, calculate the first discount, then use its result as the price for the second.
