What is 3% cash back?
"3% cash back" means you earn 3 cents for every dollar spent on eligible purchases. For instance, if you spend $100 on a qualifying purchase, you’ll receive $3 in cash back rewards.
This rate is often offered on premium credit cards for specific spending categories such as dining, travel, or groceries. Over time, these rewards can add up, providing a valuable way to save on everyday expenses.
How do you calculate 3% cash back?
To calculate 3% cash back, start by identifying the total amount of your eligible purchase. Multiply this amount by 0.03 (the decimal form of 3%) to determine the cash back you’ll earn.
For example, if you spend $200 on a purchase that qualifies for 3% cash back, you would calculate $200 x 0.03, resulting in $6 in cash back rewards. This method applies to each eligible transaction, so the more you spend, the more cash back you’ll accumulate.
