How to Use the Discount Calculator
Quickly calculate sale prices, savings, and final costs. Whether you're shopping online or in-store, know exactly how much you'll save and pay with any discount percentage or amount off.
Two Discount Types
- Percentage Off: Common for sales like "30% off" or "Buy one get one 50% off"
- Amount Off: Fixed dollar discounts like "$20 off" or coupon codes

Shopping Tips
- Compare percentage off vs. dollar amount—whichever saves more depends on the price
- Stack coupons with sales when allowed for maximum savings
- Consider if you actually need the item—a "deal" isn't a deal if you wouldn't buy it otherwise
- Don't forget to factor in tax on the discounted price
Perguntas Frequentes
Multiply original price by (1 - discount percentage). For 30% off $80: $80 x 0.70 = $56 sale price. Or calculate discount amount ($80 x 0.30 = $24) and subtract from original ($80 - $24 = $56).
Divide sale price by (1 - discount percentage). If something is $42 after 30% off: $42 / 0.70 = $60 original price. This reverse calculation helps you understand true discounts.
Calculate final prices to compare. $100 with 25% off ($75) beats $90 with 15% off ($76.50). Also compare dollars saved vs. percentage - $20 off $50 (40%) may be better than 30% off $100 ($30 off) depending on what you need.
It depends on the original price. On a $100 item, they are equal. On items over $100, $30 off saves more. On items under $100, 30% off saves more. Always calculate both ways to find the better deal.
Sequential discounts multiply, they do not add. 20% off plus 10% off is not 30% total. Its $100 x 0.80 x 0.90 = $72, equivalent to 28% off. The order does not matter mathematically, but the total discount is less than the sum.
The best deal is not buying what you do not need. A 50% discount still costs 50% of the price. Consider if you would buy it at full price and if you actually need it. Sales are most valuable on planned purchases.
