Making Sense of Discounts

The Simple Formula

Discount Amount = Original Price × (Discount% ÷ 100). Final Price = Original Price − Discount Amount. A 30% discount on £120 saves £36, leaving a final price of £84.

Stacked Discounts

Two separate 20% discounts don't equal 40% off. The second discount applies to the already-reduced price. 20% off £100 = £80. Then 20% off £80 = £64 — a total saving of £36, or 36%, not 40%.

Black Friday & Sales

Research shows many 'original' prices are inflated before sale events. Use price tracking tools to verify whether a sale price is genuinely reduced from a sustained normal price.
