Explanation & How It Works
A discount means a reduction in the normal price of any commodity or service. It is very important to understand the relation between discounts and sales tax for good budgeting and wise buying.
Double Discounts and Combination Discounts
When a shop gives a "discount of 30% and an extra 20% off at checkout," the discounts DO NOT total 50%! The second discount is applied on top of the first discount. If something costs $100, then 30% off makes it cost $70, and another 20% off of $70 saves you $14, meaning you paid only $56 (actual discount = 44%, not 50%).
Calculation Formula & Rules
Discount Amount = Original Price × (Discount Rate / 100)
Final Price = Original Price − Discount Amount
With Sales Tax = Final Price × (1 + (Tax Rate / 100))
Example Calculation
Example: A designer watch priced at $200 has a 35% discount with 8% sales tax.
- Discount:
$200 × 0.35 = $70.00 saved. - Subtotal:
$200 − $70 = $130.00. - Sales Tax:
$130 × 0.08 = $10.40. - Final Out-of-Pocket Cost: $140.40.
Psychological Tactics in Common Retail Pricing
- Charm Pricing (.99 pricing): Items priced at $19.99 create a perception in the human brain that the product is worth $10, not $20.
- Anchoring: A product with an artificially inflated MSRP ($300) to make the sale price of $150 a good bargain.
