Tool · Fake-discount calculator
Is that discount real — or fake?
Stores love a big red “% off.” But a discount only counts if the “was” price is one the item actually sold at. Enter a sale below to see what it really claims — then check the real price research in one tap.

Runs our honest BUY / WAIT / SKIP verdict from a year of real prices — the calculator above only shows the claim.
How fake discounts work
- Inflated “was” price. The reference is set high (or is a full MSRP no one pays), so the “% off” looks huge.
- The permanent “sale.” The “sale” price is just the everyday price — it never actually goes back up.
- Event pricing. A “Prime Day / Black Friday” price that matches what it cost the week before.
- Bundle anchoring. A struck-through “value” that was never a real standalone price.
The only way to know is to compare today’s price against what the item actually sold for over the past year — which is exactly what a worthitforyou verdict does.
FAQ
Can this calculator tell me if a deal is fake?

What counts as a “fake” discount?
A discount measured against a price the item never truly sold at. A “40% off” from a number no one paid is a 0% deal.
