The 15/3 Rule: Boost Your Score Without Paying Extra Debt

You pay your bills on time. You pay the full balance. Yet, when you check your credit score, it says your utilization is high, and your score has dropped. Why?

Because you are paying on the Due Date.

The credit scoring system does not look at your account in real-time. It looks at a "Snapshot" taken once a month. If you pay your bill after the snapshot is taken, the bureau thinks you are maxing out your card—even if you pay it to zero a few days later.

The 15/3 Rule is a timing strategy to ensure the "Snapshot" shows a $0 (or very low) balance.

The Mechanic: Statement Date vs. Due Date

To master this, you must understand two dates found on your bill:

• 1. The Statement Date (The Snapshot) This is the day the billing cycle closes. On this day, the bank prints your bill and sends the balance to the Credit Bureaus. This is the date that matters for your score.
• 2. The Due Date (The Deadline) This is usually 21-25 days after the Statement Date. This date only matters for avoiding interest and late fees.

The Execution Strategy

To maximize this, you can use the AZEO Method (All Zero Except One).

1. Log in to your credit card app 3 days before your Statement Closing Date.
2. Pay the current balance down to $10 to $20 (do not pay it to $0.00 yet).
3. Why leave $10? If all cards report $0, it can look like you aren't using credit at all. A tiny balance proves activity ("Paid as Agreed") while keeping utilization under 1%.
4. Let the Statement Close. The bank will report a $10 balance to Equifax/Experian.
5. Autopay: Set your autopay to pay the remaining $10 on the actual Due Date to avoid any interest.
