Cashback in one sentence

Cashback is a small share of what you already spend, returned to you by a card, app or retailer as an incentive to keep shopping with them.

That simple idea sits behind almost every rewards program. The differences are in how the value is funded, calculated and paid — which is exactly what the guides below unpack.

Frequently asked

Is cashback really free money?

Not exactly. Cashback is funded by the fees merchants pay to accept certain payment methods and by marketing budgets that reward repeat customers. You are receiving a share of that spending, so it is best understood as a discount on purchases you were already going to make — not extra income.

Does EarningPerks pay cashback or run a program?

No. EarningPerks is an independent educational site. We do not operate any rewards program, we do not pay cashback, and we have no accounts, wallets or payouts. We only explain how these programs work in general so you can understand the official terms of whichever program you choose.

Will following these guides guarantee savings?

No. Every program sets its own rates, limits and conditions, and these change over time. Our guides describe general concepts and good habits; they are not advice and they do not promise any particular result.
