Biweekly vs. Semimonthly Pay: 26 or 24 Paychecks

Biweekly means every two weeks: 26 paychecks a year. Semimonthly means twice a month: 24 paychecks a year. The yearly total is the same; the size and timing of each check are not.

The two schedules side by side

Biweekly: smaller checks, two extra

A year has 52 weeks, so a biweekly schedule produces 26 paychecks. Each one is 1/26 of yearly pay. Because most months are slightly longer than four weeks, the payday drifts earlier each month, and two months a year contain three paydays instead of two.

Every so often, the calendar lines up so that a year contains 27 biweekly paydays. Salaried employees in that year may see either a 27th check or slightly smaller checks, depending on how the employer handles it. Hourly employees are simply paid for the hours they worked.

Semimonthly: same dates, uneven hours

Semimonthly pay arrives on two fixed dates each month, which makes it easy to match with rent and bills due on the 1st. Each check is 1/24 of yearly pay, so the checks are larger than biweekly checks.

For hourly workers, semimonthly periods are awkward: a pay period might hold 10 workdays or 12, so checks vary. That is one reason the schedule is more common for salaried staff.

Budgeting on a biweekly schedule

The easiest method is to build your monthly budget on two paychecks, not 2.17. Bills are covered by two checks every month. In the two months that bring a third check, that check is free money for savings, debt or an irregular expense such as car insurance.

The common mistake is the reverse: multiplying the biweekly check by two to get "monthly income." On $52,000, that gives $4,000, while true average monthly pay is $4,333. Planning on $4,000 is safe; planning on $4,333 and paying bills from two checks is not.

Budgeting on a semimonthly schedule

Split bills between the two checks. A typical split: the first check covers rent or the mortgage; the second covers utilities, phone, insurance and savings. Because the dates never move, you can set automatic payments a day or two after each payday.

Converting between the two

• Biweekly to yearly: check × 26
• Semimonthly to yearly: check × 24
• Biweekly to semimonthly: check × 26 ÷ 24 (about 1.083)
• Semimonthly to biweekly: check × 24 ÷ 26 (about 0.923)

Weekly pay works the same way: 52 checks a year, each 1/52 of yearly pay. Monthly pay is 12 checks.

Which is better?

Neither pays more over a year. Biweekly gives you two bonus-feeling months; semimonthly gives predictable dates. Employers usually choose based on payroll costs and state law; some states regulate how often employees must be paid, so the choice is not always the employer's alone.

The pay converter accepts both schedules as inputs and shows every other period.
