About the Black Friday Savings Calculator
Black Friday deals often combine a storewide percentage discount with an additional stackable coupon code, and each discount is applied to the already-reduced price rather than the original — so two 10% discounts never simply add up to 20%.
Formula: Final Price = Original Price × (1 − Store Discount) × (1 − Coupon Discount)
The effective combined discount is always a little less than simply adding the two percentages together, because the second discount applies to a smaller, already-discounted base price.
