Calculate the final price after single or stacked discounts. See exactly how much you save with multiple discount layers applied sequentially.
When a store offers "20% off plus an extra 10% off", these are sequential (stacked) discounts, not additive. The first discount is applied to the original price, then the second discount is applied to the already-reduced price. This means 20% + 10% gives an effective discount of 28%, not 30%.
Original price: ₦10,000. First 20% off = ₦8,000. Then 10% off ₦8,000 = ₦7,200. Total savings: ₦2,800 (28% effective discount). This is important during sales events like Black Friday, Jumia sales, and Konga special offers in Nigeria.
