Credit card cashback offers are incentives provided by credit card companies that allow cardholders to earn a percentage of their spending back as cash. For example, if a card offers 1.5% cashback and you spend $1,000, you would receive $15 back. These offers can vary by card and may include higher percentages for specific categories like groceries or gas. Many credit cards also have promotional periods where cashback rates are increased for new users or during certain times of the year. It's important to read the terms and conditions, as some cards may have limits on how much cashback you can earn or require a minimum spending amount.
