About this tool

Cashback programmes return a percentage of each purchase to your account. This tool shows the exact amount you get back and what the product effectively costs after the rebate.

The calculation is straightforward (amount × rate), but seeing the net price makes it easier to compare offers across cards or platforms that advertise different rates.

Cashback is usually credited days or weeks after the purchase, and some programmes cap the monthly total. Check your programme rules for limits and exclusions.
