How to Use This Calculator
Use Single Discount to calculate the price after one discount. Use Stacked Discounts when an item has two sequential discounts — stacked discounts are applied sequentially, not added together.
Discount Formula
Sale Price = Original Price × (1 − Discount% ÷ 100)
Stacked: Final = Price × (1 − D1%) × (1 − D2%)
Effective Discount = 1 − (1 − D1%) × (1 − D2%)
Two stacked discounts of 20% and 10% give 28% total, not 30%.

Black Friday Example
Stacked Deal Calculation
Original price: R3,500. Black Friday: 30% off. Loyalty card: extra 10% off.
After 30%: R3,500 × 0.70 = R2,450
After extra 10%: R2,450 × 0.90 = R2,205
Effective discount = 37% (not 40%). Total savings = R1,295.

Frequently Asked Questions
No. When discounts are stacked, each applies to the already-reduced price. A 20% discount followed by a 10% discount gives 28% total off, not 30%. Retailers often advertise stacked discounts to make deals sound bigger than they are.
Discount% = (Original Price − Sale Price) ÷ Original Price × 100. For example, if an item was R500 and you paid R375: (500 − 375) ÷ 500 × 100 = 25% discount.
Original Price = Sale Price ÷ (1 − Discount%). For example, if something costs R680 after a 15% discount: R680 ÷ 0.85 = R800 original price.
In South Africa, retail prices are usually shown VAT-inclusive. The discount applies to the VAT-inclusive price. The discount percentage itself is the same whether you use VAT-inclusive or exclusive prices.
