Cash Back is a financial incentive offered by credit cards or retailers, where a percentage of the money spent on purchases is returned to the buyer. For example, if a card offers 2% cash back and you spend $100, you would receive $2 back. This reward can be credited to your account, used for future purchases, or sometimes redeemed as cash. Many people use cash back programs to save money on everyday expenses. These programs can vary in terms of the percentage returned and the types of purchases that qualify, making it important for consumers to choose options that align with their spending habits.
