What is the 15 3 credit card trick?

The 15/3 credit card payment method is a strategy to potentially boost your credit score by making two payments per billing cycle: one about 15 days before your statement closes (to lower reported utilization) and another around 3 days before the payment due date (to cover the rest and avoid late fees), though its actual impact on credit scoring is debated. It works by keeping your reported balance lower when the card issuer reports to bureaus, but experts note the specific timing isn't magical, and focusing on the reporting date is key.
