Your budget is wrong twice a year
If you are paid every two weeks, two months a year carry a third cheque. Averaging them away is the most common error in personal budgeting, and the easiest to fix.
Twenty-six paydays. Twelve months. The division does not come out, and that remainder is where most budgets go quietly wrong.
Multiply a biweekly cheque by 26 and divide by 12 and you get 2.17 cheques a month. It is a tidy figure, and you have never been paid it. Ten months of the year you are paid twice. Two months you are paid three times, and which two depends entirely on the calendar and on which Friday you started.
What the average does to the plan
Spreading the extra cheque across the year raises your assumed monthly income by roughly eight percent. Every decision downstream inherits that: the rent you can carry, the savings rate you believe you have, the leftover you plan against.
So ten months a year you are quietly a little short, and two months you are flush without knowing why. The shortfall is small enough to look like ordinary noise, which is exactly why it survives for years.
Plan against a normal month, and treat the third cheque as what it is: an event on a date, twice a year.
The fix is a date, not a formula
Give every income source the next date it arrives and the frequency it repeats on, then walk the actual calendar. The answer falls out: a normal month figure that is the one you are usually paid, and a named list of the months that carry more.
- Budget against the normal month, never the average.
- Know which two months carry the extra cheque before they arrive.
- Aim the extra at something specific — the heavy bill month, or the balance.
It is not a sophisticated technique. It is just refusing to divide by twelve when the world does not.
