Biweekly vs Semi-Monthly Pay

Same annual salary, split two different ways — biweekly pays 26 times a year, semi-monthly pays 24 times a year.

Per-paycheck amount by schedule

Biweekly = annual salary ÷ 26. Semi-monthly = annual salary ÷ 24. Figures are gross pay, before tax and other withholding.

Frequently asked questions

What's the actual difference between biweekly and semi-monthly pay?
Biweekly means every two weeks, on the same day of the week (e.g. every other Friday) — 26 paychecks a year. Semi-monthly means twice a month on fixed dates (e.g. the 15th and last day of the month), regardless of what day of the week that lands on — 24 paychecks a year. Same annual salary, split into a different number of pieces.
Why is each biweekly paycheck smaller than each semi-monthly one?
The same annual salary is divided by more paychecks under a biweekly schedule (26) than a semi-monthly one (24), so each individual paycheck is smaller. For a $60,000.00 salary: biweekly is $60,000.00 ÷ 26 = $2,307.69, while semi-monthly is $60,000.00 ÷ 24 = $2,500.00 per paycheck — about $192.31 more each time, even though the yearly total is identical.
What are the "three-paycheck months" people mention with biweekly pay?
Because 26 biweekly paychecks don't divide evenly into 12 months (26 ÷ 12 ≈ 2.17), two months out of most years get 3 paychecks instead of the usual 2 — the extra paycheck simply falls earlier than a purely monthly split would suggest. Semi-monthly pay never does this, since it's fixed at exactly 2 paychecks every month by definition.
Which schedule is better?
Neither pays more over a year — both add up to the same annual salary. Biweekly tends to be easier to budget around a weekly routine and delivers two "bonus" paycheck months a year; semi-monthly lines up more predictably with monthly bills like rent, since the dates are fixed. Most employers choose the schedule, not the employee, so this is generally about understanding your pay stub rather than picking one.
How do I figure out which schedule I'm on?
Check your pay stub or offer letter for either the pay dates or the number of paychecks per year. If pay always lands on the same weekday (e.g. every other Friday), it's biweekly. If it lands on fixed calendar dates (e.g. the 15th and 30th) that shift across weekdays, it's semi-monthly.
