Frequently asked questions
Multiply the original price by the discount percentage (divided by 100), then subtract that from the original. AED 500 with a 20% discount: 500 × 0.20 = 100 AED off, so you pay 400 AED.
Divide the final price by (1 minus the discount percentage expressed as a decimal). AED 400 ÷ (1 − 0.20) = AED 400 ÷ 0.80 = AED 500. The reverse mode above does this for you.
Each discount applies to the already-discounted price, not the original. 10% off + another 10% off is only 19% in total, because the second 10% is taken off the 90% remaining after the first discount. This is why shop signs say 'EXTRA 10% off sale prices' rather than 'an additional 10%'.
UAE retail prices are displayed VAT-inclusive at the counter, so discounts shown at the till already factor VAT in. For business invoicing where the discount is explicit and VAT separate, the discount reduces the net amount and VAT is recalculated on the discounted total.
Use 'Find discount %' mode. Enter the original and final of each. The one with the higher percentage is the better deal on that single item. For basket comparisons, compare the final totals instead.
BOGO = 50% total discount on two items (you pay for one of two). Buy 2 get 1 free = 33.33% total. Buy 3 get 1 free = 25%. In general, 'buy X get Y free' = Y / (X + Y) × 100 percent.
Most UAE mall stores stack a base sale percentage with a loyalty-card percentage sequentially, not additively. 'UP TO 70% + EXTRA 20%' is usually 70% off the tag, then 20% off the sale price, for a 76% combined discount (not 90%). Use Stack mode above.
