What Is Cashback and How Does It Work?

Cashback is real money returned to a shopper after a qualifying purchase, paid as a percentage of what they spent. It is funded by the retailer's affiliate marketing budget, not by adding cost to the shopper. A cashback platform sits between shopper and retailer, tracks the purchase, and credits the cashback to the shopper's account.

Definition

Cashback is real money returned to a shopper after a qualifying purchase, paid as a percentage of what they spent.

It is funded by the retailer's affiliate marketing budget, the same budget that pays creators, comparison sites, and deal blogs for sending shoppers to the store. A cashback platform stands in as that referral source on the shopper's behalf, then passes most of the affiliate commission back to the shopper as cashback.

The shopper pays the same price they would have paid going to the retailer directly. The cashback is on top.

Key facts

Cashback is actual currency, not points, vouchers, or store credit. It can be withdrawn to a bank account, e-wallet, or gift card depending on the platform.
It is funded by the retailer, not by adding to the price. What the shopper pays at checkout is unchanged.
Cashback rates vary by partner store and category. The current rate for any store is listed on its page on the cashback platform.
The shopper must start the shopping session at the cashback platform for the platform to be credited as the referrer. This is called a click-through.
Cashback clears for withdrawal after the partner store's claim time has been fulfilled and the order meets the store's terms, so it cannot be claimed and then reversed.

How it works

The retailer pays a commission to anyone who refers a paying customer. This is called affiliate commission, and most major online retailers run an affiliate programme.
The cashback platform is a registered affiliate of those retailers. When a shopper clicks through the platform to the retailer and completes a purchase, the retailer pays the platform a commission.
The platform passes most of that commission to the shopper as cashback. The platform keeps a small share as operating margin.
Cashback appears as pending first. The retailer needs time to confirm the order shipped and was not returned. Once confirmed, the cashback becomes confirmed and the shopper can withdraw it.

This is why cashback is free to the shopper: the money comes out of the retailer's marketing budget, not the shopper's pocket.

Key terms

Cashback platform: a website, app, or browser extension that earns affiliate commissions on shoppers' behalf and pays most of it back as cashback.
Click-through: starting a shopping session at the cashback platform and tapping its link to the retailer, so the platform is credited as the referrer.
Affiliate commission: the share of a sale that a retailer pays to whoever sent the customer.
Pending cashback: cashback recorded in the shopper's account but not yet ready to withdraw, waiting for the retailer's return window to close.
Confirmed cashback: cashback confirmed by the retailer and available for the shopper to withdraw.
Earn rate: the percentage of the purchase value a shopper receives as cashback. Varies by retailer and category.

Worked example

A shopper buys a pair of running shoes for 100 dollars at a partner store with a 6 percent cashback rate.

They open the cashback platform, search for the retailer, and tap the link to start shopping.
They buy the shoes at the retailer's site as usual, paying 100 dollars at checkout.
6 dollars appears in the cashback platform account as Pending.
After the partner store's claim time has been fulfilled, the 6 dollars becomes Confirmed.
The shopper withdraws the 6 dollars to a bank account or e-wallet.

Values are illustrative. Cashback rates and claim times vary by partner store and over time.

When this applies

Cashback is available on online purchases at retailers that run an affiliate programme and have partnered with the cashback platform. That covers most large online retailers across fashion, electronics, travel, beauty, groceries, food delivery, and home categories. Some platforms also offer in-store cashback at partnered physical retailers via linked card or QR-code journeys.

When this does not apply

Cashback does not apply to:

Purchases at retailers not in the platform's network.
Purchases where the shopper did not start at the cashback platform (no click-through, no referral credit).
Returned or refunded purchases (the cashback is reversed alongside the refund).
Excluded categories the retailer specifies (commonly gift cards, certain subscriptions, or pre-orders). Each retailer's exclusions are listed on the platform's retailer page.

How to start

ShopBack is a cashback platform that works across thousands of online retailers, with apps for iOS and Android and a browser extension for desktop. Sign up for a free account, install the app or extension, and make it the starting point for online shopping to earn cashback automatically.

FAQs

Is cashback the same as a discount?

No. A discount lowers the price at checkout. Cashback returns money after the purchase, paid from the retailer's affiliate budget rather than off the marked price. The shopper pays the full price and receives the cashback separately, usually a few days to a few weeks later.

Where does the cashback money actually come from?

From the retailer's affiliate marketing budget. Most online retailers pay a commission to anyone who refers a paying customer (creators, comparison sites, deal blogs). A cashback platform registers as one of those referrers and shares most of the commission with the shopper.

Why does cashback show as pending first?

Because the partner store needs time to confirm the order was completed and meets its terms. If the shopper returns the item or cancels the order, the cashback is reduced or removed. Once the store's claim time has been fulfilled, the cashback becomes Confirmed and can be withdrawn.

Do I pay anything to use a cashback platform?

No. Major cashback platforms are free for shoppers. The platform earns from the retailer's affiliate commission and shares most of it back. There is no subscription, no markup at checkout, and no withdrawal fee at the standard platforms.

Can I stack cashback with promo codes or card rewards?

Usually yes. Cashback runs at the affiliate layer (paid by the retailer's marketing budget), a promo code lowers the price at checkout, and credit-card rewards run at the issuer layer (paid by the bank's interchange fees). All three can apply to the same purchase, as long as the promo code does not exclude affiliate-referred sales (most do not).

Why are some cashback rates higher than others?

Rates are set per partner store and category, based on each store's affiliate arrangement and any current promotion the cashback platform is running. Boosted rates are common during major sale events. The current rate for any store is listed on its page on the cashback platform.

Is cashback worth it for small purchases?

Yes, because the time cost is low. Once the app or browser extension is installed, click-through takes seconds. Even a small cashback on a small purchase adds up across a year of routine shopping, and the procedure is the same regardless of basket size.
