How to budget when you're paid every two weeks

Biweekly pay means 26 paychecks a year against 12 monthly budgets, and the way to make them line up is to budget every month on two paychecks and treat the third one, in the two months a year that have it, as money outside the budget. Assign each bill to the paycheck that arrives before its due date, level the two halves of the month with a small buffer so one paycheck is not carrying all the rent, and find the three-paycheck months on the calendar in January so the extra paycheck has a destination before it lands.

Why biweekly pay and a monthly budget don't line up

Twenty-six paychecks divided by twelve months is 2.17 paychecks a month, and no month actually contains 2.17 of anything. Ten months contain two paychecks and two contain three. A budget built on the monthly average, take-home pay times 2.17, overstates what arrives in a normal month by about 8%, and the shortfall shows up as a card balance that grows in the two-paycheck months and shrinks in the three-paycheck ones.

The second mismatch is inside the month. Bills are due on fixed dates, and paychecks drift: a paycheck that lands on the 3rd this month lands on the 1st next month and the 29th of the month after. A bill due on the 2nd is sometimes paid from last month's second paycheck and sometimes from this month's first, and the budget that assumes it is always the same one is wrong half the time.

Budget the month on two paychecks

1. Set monthly income at two paychecks of take-home pay. For $2,100 per paycheck, the month has $4,200, not $4,550. The two extra paychecks a year are handled separately.
2. List the month's bills with their due dates, and put every other expense, groceries, fuel, dining out, in a spending pool.
3. Assign each bill to the paycheck that lands before it is due. Bills due in the first half of the month belong to the first paycheck, the rest to the second.
4. Give each half of the month its share of the spending pool, which is whatever that paycheck has left after its bills.

A worked example, with the halves leveled

Take-home pay is $2,100 a paycheck, paid on alternating Fridays, and the bills are the household's usual ones.

The first half of the month has $450 to live on and the second has $1,430, which is the shape most biweekly budgets take, because rent lands on one side. Two fixes work, and they combine.

• Move a due date. Most billers will move a due date on request. Moving the electric bill and the internet and phone bill to the second half shifts $250 across and leaves $700 and $1,180.
• Level the halves with a buffer. The month's spending money is $450 plus $1,430, or $1,880, so each half should have $940. Hold $490 from the second paycheck in the account until the next first paycheck, and from then on each half has $940. The first time costs a one-time catch-up of $490; after that, the buffer rolls on its own.

Either way, the budget is now the same every month regardless of which dates the paychecks land on, because each bill has a paycheck and each half has its share.

Find the two three-paycheck months

A month has three paydays when a payday falls on the 1st or 2nd, or on the 3rd in a 31-day month, since the next two come 14 and 28 days later. February almost never qualifies. Open a calendar in January, mark every payday, and circle the two months with three. They are usually about six months apart.

Nothing in the budget changes in those months. The month still runs on two paychecks, the bills are still assigned to the first two, and the third paycheck arrives with nothing assigned to it.

What to do with the third paycheck

The third paycheck is the largest single sum most biweekly households ever see that is not spoken for, and it should have a destination before it arrives. Decide in January, when you circle the months, and write it into the plan.

• Finish the emergency fund. A whole paycheck is often a month or two of the regular transfer at once.
• Pay down the highest-rate debt. An extra payment goes entirely to principal, because the regular payment already covered the month's interest.
• Fund the annual bills. Insurance and registration that come once a year can be covered by one third paycheck instead of twelve monthly shares.

The one thing not to do is let it land in checking with no label. A paycheck that reads as available is spent by the end of the month, and the household is back to wondering why 26 paychecks feel like 24.

Common mistakes

• Budgeting on the monthly average. Ten months a year come up short by about 8%, and the two long months cover it, so the budget looks fine on paper and lives on a card.
• Assigning bills by the month instead of by the paycheck. A bill due on the 2nd has no fixed paycheck unless you give it one.
• Living unevenly across the halves. Two lean weeks followed by two loose ones is the pattern of a rent-heavy first paycheck, and a buffer fixes it once.
• Treating the third paycheck as a bonus to spend. It is the only slack the year has; the bills are already paid.
• Forgetting that the paydays drift. The calendar check in January is what catches the third-paycheck months before they surprise you.

Common questions

Is this different from being paid twice a month? Yes. Twice a month is 24 paychecks on fixed dates, such as the 15th and the last day, so every month has exactly two and there is no third paycheck to plan for. Biweekly is 26 paychecks on alternating weekdays, which drift through the calendar and produce the two three-paycheck months.

What if the first paycheck can't cover the bills assigned to it? Move a due date, or build the buffer described above so part of the second paycheck waits for the next first one. A bill that is always paid late because its paycheck lands two days after the due date is a due-date problem, and most billers will change the date on request.

Should I budget by paycheck instead of by month? Assigning bills to paychecks is budgeting by paycheck; keeping the totals monthly is what makes the budget comparable from month to month and lets bills that come every three or twelve months be planned as monthly shares. Do both: monthly totals, paycheck assignments.

What about hours that vary, so the paychecks aren't equal? Budget on the smaller paycheck you reliably get, assign the bills to it, and treat anything above it the way the third paycheck is treated, as money with a destination decided in advance.

How Zypper handles this

Zypper budgets income on the schedule it actually arrives. An income category can be set to a frequency of Every two weeks, Twice per month, Every week, or Every month, and its row shows Earned against the amount, with $X remaining for what you still expect this month and $X extra when the month brought in more than you budgeted, which is what a third paycheck reads as. Bills in your spending categories count as money already spoken for from the start of the month they are due, at their usual amount before the charge arrives, so the half-month picture stays honest whichever paycheck a bill lands after, and the recurring page lists each detected bill with its next expected date. See Creating your budget and Recurring bills in your budget for the details, or get started with Zypper to budget your own two paychecks.
