Why do stacked discounts save less than adding the percentages together?

A 20% discount followed by 10% off the reduced price equals 28% total savings, not 30%. The second discount applies to a smaller base. On a $100 item: $100 → $80 (after 20%) → $72 (after 10%). You saved $28, which is 28%.

How do I calculate the original price from a discounted price?

Divide the sale price by (1 − discount rate as a decimal). If a jacket costs $72 after a 20% discount, the original price was $72 ÷ 0.80 = $90. This is useful for comparing "sale" prices to historical norms.

Are "buy one get one" deals better than percentage discounts?

BOGO effectively gives 50% off per item if you need two. A straight 40% discount on each item is better if you only need one. On a $50 item, BOGO costs $50 for two (saving $50), while 40% off costs $30 each (saving $20 per item, but $40 total for two).

What is the difference between markdown and discount?

In retail, a markdown is a permanent price reduction to clear inventory (end-of-season, discontinued items). A discount is typically temporary and conditional — a coupon, loyalty reward, or promotional sale. Markdowns tend to be deeper because the goal is liquidation.

Always check whether discounts are additive or multiplicative.
