About this tool
Shopping sales can be confusing when math is involved. "50% off plus an extra 20% off" does NOT mean 70% off. Our Discount Calculator does the math for you correctly.
Use this tool to verify prices in-store or online. We show you the exact amount you save and the final price you pay.
Usage examples
Simple Sale

$100 with 50% + 20%
Price: $100, Off 1: 50%, Off 2: 20% → Pay: $40 (Not $30!)

FAQs
How do double discounts work?
If an item is 50% off, and you have an "extra 20% off" coupon, the second discount applies to the NEW price, not the original. So $100 becomes $50, and then 20% of $50 is $10 off. Final price is $40.
How do I calculate percentage off?
Multiply the original price by the discount percentage (as a decimal). For example, 25% off $100 is 100 × 0.25 = $25 off, leaving $75 as the final price.
Can I use this for Black Friday deals?
Yes! Enter the original price and discount percentage to see exactly how much you'll save. If there are multiple discounts (like "50% off + extra 20%"), enter both to get the accurate final price.
Why don't stacked discounts add up?
Stacked discounts are applied sequentially, not added together. A 50% + 20% discount results in 60% off total, not 70%, because the second discount applies to the already-reduced price.
What is the best way to maximize sale savings?
To maximize savings: (1) Wait for major sale events (Black Friday, end-of-season clearance). (2) Stack coupons when allowed (store coupon + manufacturer coupon). (3) Use cash-back credit cards for additional 1-5% back. (4) Sign up for email lists for exclusive discount codes. (5) Check price match policies. (6) Buy during off-peak times when retailers offer bigger discounts.
How do retailers calculate their discount percentages?
Retailers calculate discounts as: Discount % = (Original Price - Sale Price) ÷ Original Price × 100. For example, if an item drops from $100 to $75, that's ($100 - $75) ÷ $100 × 100 = 25% off. Some retailers inflate "original" prices to make discounts look bigger - compare prices across stores to ensure genuine savings.
Can I stack multiple discount codes?
It depends on the retailer's policy. Some stores allow stacking (e.g., student discount + seasonal sale + email coupon), while others limit you to one code. Always try adding multiple codes at checkout. When stacking is allowed, enter each discount in our calculator to see your total savings accurately. Remember: discounts apply sequentially, not additively.
What are typical Black Friday discount percentages?
Black Friday discounts vary by category: Electronics typically 20-40% off, Clothing/Fashion 30-70% off, Home Goods 25-50% off, Toys 30-50% off. The deepest discounts (60-80% off) are usually on doorbusters with limited quantities. Compare Black Friday prices to earlier prices to verify genuine savings—some retailers raise prices before the sale to make discounts appear larger.
