Compare two deals side by side to instantly see which one is actually cheaper.
Two deals, two prices, two discounts — and no obvious way to tell which one actually costs less? Enter the price and discount for each offer, and you’ll see both final prices side by side, plus a clear result showing which deal is cheaper and by how much.
It’s a simple tool for answering a common shopping question: is the bigger advertised discount really the cheaper deal?
You can’t tell from percentages alone. A smaller discount on a lower starting price can beat a bigger discount on a higher price. This calculator applies each deal’s discount to its own starting price, compares the final prices, and shows the difference.
Final Price = Original Price × (1 − Discount % ÷ 100)
The calculator runs the formula once for Deal A and once for Deal B, then compares the results.
Say the same laptop is listed at two stores. Store A: $500 with 20% off = $400. Store B: $450 with 10% off = $405. Store A is cheaper by $5. Even though Store A started with the higher price, its larger discount brings the final price slightly below Store B.
Here’s a tie: Deal A is $60 at 25% off = $45. Deal B is $50 at 10% off = $45. Different original prices and discounts, but exactly the same final price.
Now consider a case where the larger advertised percentage doesn’t win: Deal A is $100 at 30% off = $70. Deal B is $80 at 20% off = $64. Deal A has the bigger percentage discount, but Deal B is still $6 cheaper because it started at a lower price.
Calculate the final price of each offer. The deal with the lower final price is cheaper, regardless of which one advertises the larger percentage.
Because the starting prices were different. A smaller percentage applied to a much lower price can produce a lower final cost.
The calculator compares two offers at a time. For three or more deals, compare them in pairs.
No. It compares the item prices after the discounts you enter.
The calculator treats them as equal. You can then compare non-price factors such as delivery, warranty, return policy, or convenience.
Yes, if both coupons are percentage-based. If one is a fixed amount such as $15 off, use the Coupon Savings Calculator for that offer first.
No. If the original prices are different, the 20%-off item can still have the lower final price.
If you’re working with only one offer, use the Discount Calculator for a standard percentage discount, the Coupon Savings Calculator for percentage or fixed-value coupons, the Stacked Discount Calculator for multiple percentage discounts, or the Discount + Tax Calculator when tax also needs to be estimated.
Calculate your savings from a percentage-based or fixed-amount coupon.
