Multiply the original price by the discount percentage divided by 100, then subtract from the original. For 25% off $80: $80 × 0.25 = $20 discount, sale price = $60.
Discounts are applied sequentially. 30% off $100 = $70. Then 20% off $70 = $56. The total discount is $44 or 44%, not 50%. The second discount applies to the reduced price.
The effective discount equals Y/(X+Y). Buy 2 Get 1 Free means you get 3 items for the price of 2, which is a 33.3% discount per item.
The "What If You Invested the Savings?" section shows how your discount savings grow over time at a 7% annual return. For example, saving $20 per shopping trip weekly for 5 years could grow to over $6,000 with compound interest, turning small savings into real wealth.
