Discount Calculator

How discounts are calculated

A single discount is simple: the discount amount is price × percentage ÷ 100, and the final price is what is left over. For example, 25% off 80.00 saves 20.00 and leaves 60.00 to pay.

Why two discounts do not simply add up

When a shop takes an extra percentage off an already reduced price, the second discount applies to the smaller amount, not the original. 20% followed by 10% off 100.00 gives 80.00, then 72.00 — a real saving of 28%, not 30%. This calculator always applies discounts sequentially so the result matches the till.

Everyday examples

• Seasonal sale: 150.00 with 30% off = 45.00 saved, 105.00 to pay.
• Sale plus coupon: 200.00 with 40% off and an extra 15% coupon = 102.00 to pay, 49% saved.
• Clearance: 59.99 with 70% off = 17.997 rounded to 18.00 to pay.
