Guidance

Tips & Best Practices

💡
Fixed vs. Percentage: A fixed $10 discount is better than 10% off for items under $100.
💡
The Order Matters: Most stores apply percentage discounts sequentially, not additively (e.g., 20% + 10% is actually a 28% total reduction, not 30%).
💡
Don't Forget Tax: A "great deal" can sometimes be mitigated by high local sales tax—always include it in your final math.
💡
Use the History Tape: Compare different sale scenarios side-by-side to find the best deal.

Answers

Frequently Asked Questions

Q How is a sale price determined from a percentage discount?

Discount Amount = Original Price × (Discount % / 100). Final Price = Original Price - Discount Amount. For example, a $80 jacket at 25% off has a discount of $80 × 0.25 = $20, resulting in a final price of $60.

Q How do stacking discounts work (e.g. 30% off plus extra 20% off)?

Stacking discounts apply sequentially, not additively. For a $100 item: 30% off reduces price to $70. The extra 20% off applies to $70 ($70 × 0.20 = $14), yielding a final price of $56 (an effective 44% total discount, not 50%).

Q What is the procedure to calculate original price if you only know the sale price?

Original Price = Sale Price / (1 - [Discount % / 100]). If you paid $60 after a 25% discount: Original Price = $60 / 0.75 = $80.
