What is a Discount?
A discount is a reduction in the original price of a product or service. Discounts are typically expressed as a percentage (e.g., 20% off) or as a fixed amount (e.g., $50 off). Understanding how discounts work helps you make better purchasing decisions and maximize your savings.
Amazing Discount Facts
Black Friday Psychology
Studies show retailers often inflate prices weeks before Black Friday, making the 'discounts' less impressive than they appear.
The 99-Cent Effect
Prices ending in .99 can make discounts seem larger. A $20.99 item marked down to $15.99 feels like more savings than $21 to $16.
Anchor Pricing
Showing a crossed-out 'original' price significantly increases perceived value, even when the original price was artificially high.
Loss Aversion
Framing discounts as 'you save $50' is more effective than 'now only $150' because people hate losing money more than they enjoy gaining it.
Coupon Addiction
Studies show people will buy items they don't need just to use a discount coupon, often spending more money than they save.
Math Mistakes
Most shoppers don't calculate actual savings, leading to poor decisions. A 60% discount on an overpriced item might cost more than full price elsewhere.
How to Calculate Discounts
To calculate the final price after a discount, multiply the original price by the discount percentage, then subtract that amount from the original price. For example: $100 with 25% off = $100 - ($100 × 0.25) = $100 - $25 = $75.
Formula:
Final Price = Original Price - (Original Price × Discount%)
Multiple Discounts Explained
When multiple discounts are applied, they compound sequentially, not additively. For example, 20% off then 10% off is NOT 30% off. The second discount applies to the already-reduced price. Example: $100 → 20% off = $80 → 10% off = $72 (effective 28% discount, not 30%).
Fixed Amount vs Percentage Discount
Fixed discounts (e.g., $25 off) are better for lower-priced items, while percentage discounts (e.g., 25% off) are better for higher-priced items. Use our compare mode to see which deal saves you more money.

Smart Shopping Tips
Always compare the final price, not just the discount percentage. A 50% off sale on an overpriced item might still be more expensive than a 20% discount on a fairly-priced competitor. Calculate the actual savings amount to make informed decisions.
Common Discount Scenarios
Black Friday sales, seasonal clearances, coupon stacking, loyalty discounts, bulk purchase discounts, early bird specials, and flash sales all use different discount strategies. Understanding how to calculate each helps you identify genuine savings.
Discount Myths vs Reality
MYTH: Multiple discounts add up to larger savings
Reality: Discounts compound, not add. Two 20% discounts equal 36% off total, not 40% off.
MYTH: Higher discount percentages always mean better deals
Reality: A 70% discount on an overpriced item might still cost more than a 20% discount on a fairly priced competitor.
MYTH: Sale prices always represent genuine savings
Reality: Some retailers inflate 'original' prices before applying discounts to make savings appear larger than they are.
MYTH: Fixed amount discounts are always better than percentage discounts
Reality: It depends on the price. $20 off is better on a $50 item, but 20% off is better on a $200 item.
MYTH: You should always use the biggest discount available
Reality: Consider minimum purchase requirements, shipping costs, and whether you actually need the item.
MYTH: Clearance items offer the best discounts
Reality: Clearance often means old inventory, defective items, or seasonal goods you might not want or use.
Discount Calculation Examples
25% off $200 item
Calculation: $200 - ($200 × 0.25) = $200 - $50 = $150
Result: Final price: $150, You save: $50
Buy-One-Get-One 50% off on $60 items
Calculation: $60 + ($60 × 0.50) = $60 + $30 = $90 for two items
Result: Effective discount: 25% per item
Multiple discounts: 30% then 20%
Calculation: $100 → 30% off = $70 → 20% off = $56
Result: Effective discount: 44% (not 50%)
Compare: $50 off vs 40% off on $150
Calculation: Fixed: $150 - $50 = $100 | Percent: $150 - $60 = $90
Result: 40% off is the better deal
Frequently Asked Questions
How do I know if a discount is actually a good deal?
Research the item's regular price at multiple retailers. Use price tracking websites to see historical pricing. Calculate the final price, not just the discount percentage.
What's the difference between markup and discount?
Markup is added to cost to set selling price. Discount is subtracted from selling price. A 50% markup followed by a 50% discount doesn't return to original cost.
How should I handle minimum purchase requirements for discounts?
Only meet minimums if you were already planning to spend that amount. Don't buy unnecessary items just to qualify for a discount.
Are there tax implications for business discounts?
Business discounts are typically calculated before taxes. Consumer sales tax is usually applied to the discounted price, not the original price.
How do loyalty program discounts typically work?
Most loyalty discounts are percentage-based and apply to your total purchase. Some exclude sale items or have spending thresholds.
What's the best strategy for using multiple discount codes?
If stacking is allowed, apply percentage discounts before fixed amount discounts for maximum savings. Always read the fine print for restrictions.
