📐 Discount Calculation Formulas
Percentage Discount
Discount = Price × (Percent ÷ 100)
Final = Price - DiscountExample: $80 with 25% off
Discount: $80 × 0.25 = $20
Final: $80 - $20 = $60
Find Original Price
Original = Sale Price ÷ (1 - Discount%)
Example: $60 sale price (25% off)
Original: $60 ÷ 0.75 = $80

🛍️ Case Study 1: Clothing Sale Comparison
You're shopping for a $120 jacket. Store A offers 30% off, Store B offers $40 off. Which is better?
- Store A: $120 × 30% = $36 off → $84
- Store B: $120 - $40 = $80
Store B saves $4 more! The fixed $40 off equals 33.3% discount on this price.

💡 Smart Shopping Strategies
Calculate Actual Dollar Savings
Don't be fooled by large percentages. A 50% off $10 item saves less than 10% off $100.
Compare Final Prices, Not Discounts
A smaller discount from a lower-priced retailer may still be the better deal.
Consider Total Cost of Ownership
Factor in shipping, taxes, return policies, and warranties before deciding.
Time Your Purchases Strategically
End-of-season clearances, holiday sales, and model year changes offer the best deals.
Use Price Tracking Tools
Set price alerts to know if "sale" prices are actually below historical averages.
Ask About Price Matching
Many retailers will match competitors' prices or adjust if an item goes on sale after purchase.
📅 Best Times to Find Discounts
| Time Period | Best Categories | Typical Savings |
|---|---|---|
| January | Winter clearance, holiday decor, fitness equipment | 50-75% off |
| Presidents Day (Feb) | Mattresses, furniture, appliances | 30-50% off |
| Memorial Day (May) | Outdoor furniture, grills, appliances | 20-40% off |
| July 4th / Prime Day | Electronics, summer items, clothing | 20-50% off |
