Calculate Your True Savings
Is that "30% Off + an extra 15% at checkout" deal actually a good price? Retailers love using complex discount stacking to confuse shoppers. Our Discount Calculator instantly reveals the exact final price and total cash saved so you can shop smarter.
The Trap of Double Discounts
One of the most common retail tricks is "Stacking Discounts" (e.g., An item is 50% off, and you have a 20% off coupon). This does NOT equal 70% off!
- If a $100 jacket is 50% off, the new price is $50.
- If you apply a 20% coupon to that, you are taking 20% off the $50 (which is $10).
- The final price is $40. Your total savings is 60%, not 70%.
- Use our tool to quickly calculate these stacked discounts to avoid being misled by aggressive marketing.
