How to Use This Calculator
Choose your calculation mode based on what you know. "Percent Off" if you know the discount percentage, "Find Discount %" if you know the sale price, or "Amount Saved" if you know the dollar savings.
Enter the original price - this is the regular price before any discounts are applied.
Use the quick buttons to instantly see common discount amounts, or enter your own percentage for precise calculations.
The reference table shows all common discount percentages for the price you entered, making it easy to compare deals.
Understanding Your Results
The Sale Price is what you'll actually pay after the discount is applied. This is the most important number when comparing deals.
You Save shows the total dollar amount of your savings - the difference between the original price and sale price.
Discount Percent tells you what portion of the original price is being removed. Higher percentages mean bigger savings (relative to the original price).
Use the Quick Reference table to see how different discount percentages would affect the same item, helping you evaluate if a sale is really a good deal.
Frequently Asked Questions
How do I calculate percent off?
To calculate percent off: Multiply the original price by the discount percentage, then divide by 100. Subtract this from the original price. For example, 25% off $80: (80 × 25) ÷ 100 = $20 discount, so the sale price is $60.
How do I find the discount percentage?
To find the discount percentage: Subtract the sale price from the original price to get the discount amount. Divide the discount by the original price and multiply by 100. For example: Original $100, Sale $75. Discount = $25. Percentage = (25 ÷ 100) × 100 = 25% off.
What does 'percent off' mean?
Percent off means the reduction from the original price expressed as a percentage. For example, '30% off' means you pay 70% of the original price. A $100 item at 30% off costs $70.
How do I calculate 20% off a price?
To calculate 20% off: Multiply the price by 0.20 (or divide by 5) to find the discount, then subtract from the original. Quick shortcut: 20% off means you pay 80%, so multiply the price by 0.80. Example: $50 × 0.80 = $40 final price.
Is a bigger discount always better?
Not always. Compare the final prices, not just the percentages. A 50% discount on an overpriced item might still cost more than a 20% discount on a competitively priced alternative. Always check the final price against other options.
How do stacking discounts work?
When discounts stack, they're applied sequentially, not added. For example, 20% off then 10% off doesn't equal 30% off. Instead: Start with $100, apply 20% ($80), then apply 10% to $80 ($72). Total discount is actually 28%, not 30%.
What's the difference between 'percent off' and 'percent of'?
Percent off is the reduction: 25% off $100 = $75 final price. Percent of is the result: 25% of $100 = $25. They're related: 25% off means you pay 75% of the original (100% - 25% = 75%).
