Smart Shopping Tips
- Compare Dollar Savings: A 50% discount on $20 saves $10, same as 20% off $50 - compare actual savings, not just percentages
- Stack Discounts Carefully: 20% off then 20% off is NOT 40% off - it's 36% total (each applies to remaining price)
- Watch for Marketing Tricks: Stores may raise prices before sales - research typical prices to spot fake 'deals'
- Calculate Per-Unit Cost: Discount doesn't always mean best value - calculate price per ounce/item to compare
- Factor in Tax: Don't forget sales tax when budgeting - a $100 item at 20% off plus 8% tax is $86.40
- Know When to Wait: Use price tracking tools to see if discounts will likely improve (post-season clearances, etc.)
Frequently Asked Questions
How do I calculate a percentage discount?
Multiply the original price by the discount percentage (as a decimal). For example, 25% off $80: $80 × 0.25 = $20 discount. Subtract from original: $80 - $20 = $60 final price. Our calculator does this instantly for any discount.
How do stacked discounts work?
Stacked discounts apply sequentially, not additively. For example, 20% off then 10% off a $100 item: First discount: $100 - $20 = $80. Second discount: $80 - $8 = $72 final (28% total discount, not 30%). Each discount applies to the new reduced price, not the original.
What's better: percentage off or dollar amount off?
It depends on the original price. On expensive items, percentage discounts often save more (20% off $500 = $100 saved). On cheap items, fixed amounts may be better ($5 off $15 = 33% discount). Calculate both to compare which gives better savings for your specific purchase.
How do I calculate the original price from a sale price?
Divide the sale price by (1 - discount percentage as decimal). For example, if an item is $60 after a 25% discount: $60 ÷ 0.75 = $80 original price. Our reverse calculator does this automatically when you know the sale price and discount percentage.
Should I calculate discount before or after tax?
Typically, discounts apply to the pre-tax price, then sales tax is added to the discounted amount. For example, $100 item with 20% off and 8% tax: ($100 - $20) × 1.08 = $86.40. Some regions or stores may differ, but this is the standard calculation.
What does 'buy one get one 50% off' really mean?
This means the second item is half price, equaling 25% off the total of two items (not 50% off). If items are $40 each: first is $40, second is $20, total $60 for two. That's $80 originally, so you save $20, which is 25% off total purchase. Our calculator can help verify these offers.
Why Use a Discount Calculator?
Mental math during shopping leads to errors, especially with stacked discounts or when comparing deals. A discount calculator ensures accuracy, helps you verify advertised savings are genuine, enables quick comparison between different sales, and reveals the true cost after all discounts and taxes. Whether budgeting for purchases, checking if a 'deal' is worth it, or planning business sale pricing, accurate discount calculation prevents overspending and ensures you're getting the value you expect. The ability to stack multiple discounts and add tax makes it invaluable for real-world shopping scenarios.
