Read the final price, the discount amount and your total savings.
Frequently asked questions
How do I calculate a discount?
For a percentage off, discount = original price × rate / 100 and the price after discount = original − discount. For a flat amount, the discount is simply subtracted.
Does tax change the discount?
No. Any tax is added on top of the already-discounted price, so the amount you save stays the same as the discount itself.
Is my data safe?
Yes. The calculation is done entirely inside your browser — no prices are sent anywhere.
