As you make purchases using your cash back credit card, the cash back rewards accumulate based on the percentage offered. For example, if you spend $100 on eligible purchases and the cash back rate is 1%, you would earn $1 in cash back rewards.
With a cash back credit card, a percentage of your eligible purchases is returned to you in the form of cash rewards. The cash back amount is typically a percentage of the purchase price, such as 1%, 2%, or more, depending on the card's terms.
