Discount 1 + Discount 2What to consider when using discounts
A discount can make an offer more attractive, but the percentage alone does not show its full financial effect. Consider the final price, total savings and impact on your pricing before applying a promotion.
Check the Final Price
A larger discount means a lower selling price. Businesses should check whether the discounted price still covers relevant product, transaction and operating costs.
Compare the Actual Saving
The percentage discount can look significant, but the amount saved shows the actual monetary value of the offer. Compare both when evaluating a promotion or purchase.
Calculate Stacked Discounts Separately
Sequential discounts should not normally be added together. Each additional discount is applied to the price remaining after the previous discount.
Consider Quantity
The discount percentage may stay the same, but buying or selling multiple units changes the total original value, total savings and final amount.
Business tip: Before launching a promotion, compare the normal selling price, discounted price and resulting savings. A promotion that increases sales volume may still reduce profitability if the discounted price leaves insufficient margin.

Common mistakes when calculating discounts
Discount calculations are straightforward, but a few common mistakes can produce the wrong final price or give a misleading view of the actual saving.
Adding Stacked Discounts Together
A 20% discount followed by another 10% discount does not equal 30% off. The second discount applies to the already-reduced price, giving an effective discount of 28%.
Using the Wrong Original Price
Discount percentage and savings should normally be calculated against the correct original price. Using an already-discounted price as the starting value changes the result.
Confusing Savings with Final Price
The amount saved is the value removed from the original price. The final price is what remains after that saving has been deducted.
Ignoring Profitability
For businesses, a promotion should not be evaluated only by its discount percentage. Check whether the resulting selling price still provides an acceptable margin after relevant costs.

Discount Calculator — Frequently Asked Questions
How do I calculate a discounted price?
Multiply the original price by one minus the discount percentage expressed as a decimal. For example, 20% off QAR 100 gives a final price of QAR 80.
How do I calculate the discount percentage?
Subtract the sale price from the original price, divide the saving by the original price, then multiply by 100.
How do stacked discounts work?
Each discount is applied sequentially. The second discount applies to the price remaining after the first discount.
Is 20% off plus another 10% off equal to 30%?
No. A 20% discount followed by a 10% discount produces an effective total discount of 28%.
Does quantity change the discount percentage?
No. Quantity changes the total original value, total savings and final total, but the percentage discount remains the same.
