Deal Savings & Discount Calculator
See the real discount and what you save — then test it against the typical market price to catch an inflated “was” number dressed up as a bargain.
How good is this deal?
A discount is only as honest as its starting price
“50% off” means nothing until you know what it’s 50% off of. Sellers anchor you to a high list price so the sale price feels generous, but the only number that matters is what the item truly costs elsewhere. Compare against that, not against the crossed-out figure on the tag.
This calculator gives you both views. It reports the advertised discount off the list price, and — when you add a typical market price — it tells you whether the sale actually beats the going rate or just looks like it does. For multi-packs, the per-unit price cuts through “bigger pack, better value” claims that often aren’t.
Frequently Asked Questions
How do I calculate a discount percentage?
Subtract the sale price from the list price to get the amount saved, divide that by the list price, and multiply by 100. A $100 item on sale for $60 is a $40 saving, and 40 ÷ 100 = 40%. This tool does it instantly and also shows the final price and, optionally, the price per unit.
Why compare against a typical market price?
Because the 'list' or 'was' price is set by the seller and is easy to inflate. A retailer can mark an item up to $150, then advertise it at $90 as '40% off' — even though it usually sells for $80 elsewhere. Enter that $80 as the typical market price and the tool will tell you the discount is a fake: you'd actually pay more than the going rate.
What counts as a real deal?
A real deal is one where the price you pay is genuinely below what the item reliably sells for elsewhere. Check the sale price against a couple of independent sources or a price-history record, not against the seller's own crossed-out number. If the sale price beats the typical price, this tool marks it as a genuine deal.
Estimates only. Verify the typical market price against independent sources before treating a discount as real.
