Fun Facts

• The concept of percentage-based discounts dates to the late 19th century when department stores like Macy's pioneered 'marked-down' pricing to attract urban shoppers.
• Black Friday, the biggest US discount shopping day, generated $9.8 billion in online sales in 2023 according to Adobe Analytics — a 7.5% increase over 2022.
• The psychological 'left-digit effect' means $9.99 feels significantly cheaper than $10.00 to consumers, even though the difference is just one cent — a pricing trick dating to the 1880s.

FAQ

Single or multi-step discount?

Both. Single: one percentage off. Multi-step: 20% off, then 15% off the discounted price (common in store sales). The tool computes the effective final percentage.

What about BOGO?

Toggle — buy-one-get-one at N% off. Effective discount on the bundle is shown. Useful for evaluating whether the deal is actually good.

Tax before or after discount?

Configurable. Most US retailers apply discount then tax. Some sales contexts (coupons vs price changes) differ — check your local rules.

Does it handle tiered discounts?

Brackets like 'spend $50 save 10%, spend $100 save 20%'. Input the tiers; the tool figures out which applies and the savings.
