How Discount Calculations Work
Understanding price reductions helps you make smarter purchasing decisions and evaluate store deals accurately.
1. Percentage Off Formula
When a store offers a percentage discount, your total savings depend directly on the item’s original price.
Final Price = Original Price − Discount Amount
Practical Example: An item costs $200 and has a 15% discount.
- Discount Amount = $200 × (15 ÷ 100) = $30
- Final Price = $200 − $30 = $170
2. Fixed Amount Off Formula
A fixed discount subtracts a specific dollar amount directly from the original price regardless of percentages.
Savings Percentage = (Fixed Discount Amount ÷ Original Price) × 100
Practical Example: An item costs $200 and offers $30 off.
- Final Price = $200 − $30 = $170
- Savings Percentage = ($30 ÷ $200) × 100 = 15%
Percentage Off vs. Fixed Amount Off
Comparing discount types helps you determine which deal offers greater value.
| Feature | Percentage Off | Fixed Amount Off |
|---|---|---|
| Calculation Method | Scales proportionally with price | Flat monetary deduction |
| Best Used On | Higher-priced items (e.g., electronics, furniture) | Lower-priced items (e.g., groceries, small apparel) |
| Savings Potential | Higher savings as original price increases | Static savings regardless of price increases |
| Example Deal | 20% off $300 = $60 savings | $20 off $300 = $20 savings |
How Stacked Discounts Work
Retailers sometimes advertise double discounts, such as “Take 20% off, plus an extra 10% off at checkout.”
Double discounts are applied sequentially, not added together. A 20% discount followed by a 10% discount does not equal 30% off.
- Original Price: $100
- First Discount (20% off): $100 − $20 = $80
- Second Discount (10% off remaining $80): $80 − $8 = $72 Final Price
- Total Savings: $28 (an effective discount rate of 28%, not 30%)
