Why "40% + 10%" is not 50% off
An extra discount applies to the already-reduced price. So 40% off followed by another 10% off gives a total discount of 46%, not 50%. This calculator shows your real effective discount.
Frequently asked questions
How do I calculate a discount percentage from prices?
Discount % = (MRP − Sale price) ÷ MRP × 100. You can also use the Percentage Calculator.
Is the flat coupon applied last?
Yes. Here it is subtracted after the percentage discounts, which is how most shops apply it.
