How Discount Formulas Work
A discount reduces the selling price of a product by a percentage of its original value. Three fundamental formulas power every discount calculation — and they are interchangeable depending on which value you know and which you are solving for.
Formula 1 — Sale Price from Discount %
Sale Price = Original Price × (1 − Discount % ÷ 100)
Example: An AED 500 jacket with a 30% discount sells for AED 500 × 0.70 = AED 350. Source: Investopedia — Discount.
Formula 2 — Discount % from Two Prices
Discount % = ((Original − Sale) ÷ Original) × 100
Example: A dress marked at AED 400 but selling at AED 300 has a discount of ((400 − 300) ÷ 400) × 100 = 25%.
Formula 3 — Original Price from Sale Price + Discount %
Original Price = Sale Price ÷ (1 − Discount % ÷ 100)
Example: A bag on sale for AED 600 after a 40% discount had an original price of 600 ÷ 0.60 = AED 1,000. This is the most useful formula during Dubai Shopping Festival or Dubai Summer Surprises when original price tags are removed.
The Stacked Discount Myth
Many shoppers believe that a 30% off + 10% extra off = 40% total. This is incorrect. Stacked discounts are sequential, not additive. Here is how the math actually works:
| Step | Calculation | Price (on AED 1,000) |
|---|---|---|
| Original price | — | AED 1,000 |
| After 30% off | 1,000 × 0.70 | AED 700 |
| After extra 10% off | 700 × 0.90 | AED 630 |
| Effective discount | ((1,000 − 630) ÷ 1,000) × 100 | 37% |
The retailer benefits from this mechanism because the second discount is calculated on a smaller base. The mathematical formula for effective stacked discount is: Effective % = 100 − ((100 − D1) × (100 − D2) ÷ 100)
UAE VAT on Discounted Items
Per the Federal Tax Authority (FTA), UAE VAT at 5% is always charged on the discounted sale price, not the original marked price. This is codified in the UAE VAT Law (Federal Decree Law No. 8 of 2017) under the definition of the "consideration" for a supply. Source: UAE Federal Tax Authority — VAT
Practical example: An electronics item priced at AED 3,000 is on sale at 20% off = AED 2,400 sale price. VAT = 5% × 2,400 = AED 120. Total at the counter = AED 2,520 — not AED 2,550 (which would be 5% of the original AED 3,000).
Calcureal automatically applies the FTA rule when your selected currency is AED. The UAE VAT panel appears in the results for all AED calculations.
Worked Examples
Dubai Summer Surprises
A Nike jacket at Dubai Mall is AED 890, marked 35% off for DSS.
Sale = 890 × (1 − 0.35) = AED 578.50. VAT = 5% × 578.50 = AED 28.93. Total = AED 607.43.
You save AED 311.50 (35%).
Stacked Coupons at Noon.com
A phone case listed at AED 150 has a 20% site sale + extra 15% with a coupon code.
After 20%: 150 × 0.80 = AED 120. After 15%: 120 × 0.85 = AED 102. Effective discount: 32%, not 35%.
You save AED 48 — 3% less than you thought.
Shopping Festival Receipt Check
A handbag is priced at AED 720 during DSF. The original tag is missing — you only know it's 40% off.
Original = 720 ÷ (1 − 0.40) = 720 ÷ 0.60 = AED 1,200.
The bag was originally AED 1,200. You saved AED 480.
Frequently Asked Questions
How do I calculate a discount percentage?
Divide the discount amount by the original price and multiply by 100. If an item is AED 200 and sells for AED 150, the discount is (50 ÷ 200) × 100 = 25%. Use the "Find Discount %" tab above to do this automatically.
Do stacked discounts add up to their combined total?
No. A 30% + 10% stacked discount yields 37% off — not 40%. Each successive discount is applied to the already-reduced price. This is a common retail technique that makes deals appear larger than they are. Always verify with our Stacked Discounts tab.
Is UAE VAT charged on the original price or the discounted price?
On the discounted (sale) price, per FTA rules. If an item originally costs AED 100 and has a 20% discount, VAT is 5% of AED 80 = AED 4, making the final price AED 84 — not AED 85 (which would be 5% of the original AED 100).
What is a good discount percentage?
As a benchmark: 10–19% is a minor deal, 20–29% is moderate, 30–49% is significant, and 50%+ is exceptional. Clearance and end-of-season sales often hit 70–90%. Calcureal automatically rates every result with a deal quality badge to help you judge.
How do I find the original price when I only know the sale price and discount?
Divide the sale price by (1 − discount % ÷ 100). Example: a bag on sale for AED 375 after a 25% discount had an original price of 375 ÷ (1 − 0.25) = 375 ÷ 0.75 = AED 500. Use the "Find Original Price" tab above. This is especially useful during Dubai Shopping Festival when the original price tag is missing.
How does a BOGO (Buy One Get One Free) work mathematically?
In a BOGO deal, you buy 2 items and pay for 1, so you effectively get 50% off per unit. Our Stacked Discounts tab has a dedicated BOGO mode: enter the unit price and it calculates your effective per-item cost with UAE VAT if you're shopping in AED.
