A discount calculator helps you quickly find out how much you save and what the final price will be after a percentage discount is applied. Whether you're shopping in a sale, applying a trade discount, or running a promotion, this tool gives you the answer instantly.
Follow these steps:
Formula:
Discount Amount = Original Price × (Discount % ÷ 100)
Sale Price = Original Price − Discount Amount
Example 1
£100 with 20% off → Save £20 → Pay £80
Example 2
£250 with 15% off → Save £37.50 → Pay £212.50
Example 3
£49.99 with 50% off → Save £25.00 → Pay £25.00
What is the difference between discount and markdown?
A discount is a reduction from the selling price, often temporary. A markdown is a permanent
reduction in the listed price of a product.
How do I calculate 20% off a price?
Multiply the price by 0.20 to find the discount amount, then subtract it from the original price.
For example, 20% off £80 = £80 × 0.20 = £16 saved, so you pay £64.
Can I stack discounts?
Stacked discounts are not simply added together. A 20% discount followed by a 10% discount
is not 30% off — it is 28% off in total, because the second discount is applied to the
already-reduced price.
