My wife recently made a schedule of each payday, and what bills needed to be paid.  Before this, I had paid each bill a few days before the due date, but now I can look at the chart on payday, and see what bills I need to pay from this.

What I noticed was that my bills were dropping quicker because instead of waiting a week or two to pay it, I was paying them right after payday, and thus avoiding part of the monthly interest charges.

Each day adds extra interest that you owe.  If you know you have to pay it out of your current paycheck, do it as soon as possible, and avoid more charges.  Worked for us.
