Quick answer: Cashback is money returned to a shopper after a purchase — typically as a percentage of the order value. Sources include credit cards, cashback websites, brand loyalty programs, and merchant promotions.
The full definition
Cashback (also written "cash back") is a retroactive discount: rather than reducing the price at checkout the way a coupon does, cashback returns a portion of the amount you spent back to you after the transaction is confirmed. Sources of cashback fall into four buckets:
Cashback websites + apps — third-party platforms (Rakuten, TopCashback, Quidco, CashKaro) that earn affiliate commissions from merchants and share most of it with users.
Cashback credit cards — card issuers refund a percentage (typically 1-5%) of every transaction.
Brand loyalty programs — store-specific cashback in the form of "points" redeemable at the same brand.
Merchant-direct cashback — promotional cashback offered by the merchant on specific products or campaigns.

How cashback works mechanically
When you click through a cashback site to a merchant, an affiliate tracking cookie is set. If you complete a purchase within the tracking window (usually 1-30 days), the merchant pays the cashback site a commission — typically 3-12% of order value. The cashback site keeps a portion (their cut) and credits the rest to your account.
Cashback typically goes through three states:
Pending — credited to your account immediately after the purchase. Not yet withdrawable.
Confirmed — after 30-90 days (when the merchant's return window closes and the order is final), pending cashback becomes confirmed.
Paid out — confirmed cashback is transferred to your bank, wallet, or gift card. 1-5 business days depending on platform.
Why cashback sometimes fails to track
Ad blockers or privacy extensions blocked the affiliate tracking cookie
You clicked another link (a different cashback site, a search ad) between the cashback click and purchase
The merchant has category exclusions and your items don't qualify
You used a different device for the click and purchase (mobile/desktop split)
Network error during the redirect chain
How to maximize cashback
Always click through a cashback site BEFORE adding to cart
Stack with a coupon code (entered at checkout) + a cashback credit card
Pause ad blockers on cashback-tracking domains
Don't click ANY other links during the purchase flow
Time large purchases for "boosted" cashback rate periods

How does cashback work?
When you buy through a cashback link or with a cashback card, the merchant pays commission. A portion is returned to you — usually 1-10% of order value.
Is cashback the same as a coupon?
No. A coupon reduces price BEFORE payment. Cashback returns money AFTER payment. You can stack both.
How long does cashback take to credit?
Pending immediately, confirmed in 30-90 days, paid out 1-5 business days after confirmation.
Why might cashback not track?
Ad blockers, multiple affiliate clicks, excluded categories, or network errors.
