If you're paid every other week, you get 26 paychecks a year, not 24. Most months bring two of them. Two months a year bring three, and every so often the calendar adds a 27th payday.
The extra checks only help if the monthly budget doesn't count on them. A lot of budgets take the yearly pay and divide it by 12, which actually spreads the extra checks across every month and spends them without anyone noticing. Build the budget on two paychecks a month instead. Then the third one has no bills waiting for it.
That matters in Dynamic Banking, because every paycheck lands on the line of credit first. Dynamic Banking means running your income through a line of credit, so each dollar lowers the balance, and the interest, until your bills need it. A short video I made, Dynamic Banking in Action, charts one month of it. A $5,000 paycheck lands on a $7,000 balance, the mortgage and the credit card come back out, and the average daily balance, which means the average of what you owed at the end of each day, ends up around $3,441 instead of $6,000 to $7,000.
In a three-paycheck month, the third check lands on the line of credit and nothing draws it back out. It becomes principal paid down for good. Say each check is $2,500. The two extra checks put $5,000 a year against the balance, and on a line of credit charging 8.5%, $5,000 off the balance saves about $425 a year in interest for as long as it stays off. It also brings your next chunk sooner. A chunk is a lump sum you move from the line of credit to a loan's principal, and your next chunk is due once the balance falls below one month's take-home pay.
Your payroll calendar shows which months carry the third payday, and they shift from year to year. Some employers take benefit premiums out of only the first two checks each month, which makes the third check a little bigger than the others. If you're paid twice a month, on the 15th and the last day, you get 24 checks and no third payday, so this one doesn't apply to you.
The risk is spending creep, the same thing that breaks most plans. A third paycheck feels like a bonus, and once it's sitting on the line of credit as available credit, it's easy to spend. Leaving it there is a decision you make ahead of time, and the math works until spending creep breaks it covers how to catch the drift early.
Open your employer's payroll calendar for next year, mark the two months with a third payday, and set a reminder in each one to leave that deposit on the line of credit.
