What Is a Discount Calculator?
A discount calculator helps you calculate the final price after a discount and how much you save. This discount calculator UK is perfect for shoppers comparing deals and sales.
How to Use the Discount Calculator
Enter the original price, select discount mode (percentage or fixed amount), and enter the discount value. Click Calculate Discount to see the final price and savings.
How Discount Is Calculated
Percentage Discount: Final Price = Original Price × (1 - Discount %)
Fixed Amount Discount: Final Price = Original Price - Discount Amount
Fixed Amount Discount: Final Price = Original Price - Discount Amount
Discount Example
Example 1: £100 original, 20% off
- Discount: £100 × 20% = £20
- Final price: £100 - £20 = £80
- You save: £20
Example 2: £100 original, £20 off
- Final price: £100 - £20 = £80
- You save: £20
Understanding Discounts
- Percentage Off: A percentage of the original price is deducted
- Fixed Amount Off: A fixed amount is deducted from the price
- Sale Price: The price after the discount
- Savings: The amount you save
