Biweekly vs. semimonthly pay

These two pay schedules sound similar and are constantly confused — but they produce a different number of paychecks a year, which matters more than people expect.

Biweekly: every two weeks, 26 paychecks a year

Biweekly pay means you're paid every two weeks, always on the same day of the week — every other Friday, for example. Since a year has slightly more than 52 weeks, this schedule produces 26 pay periods most years, and occasionally 27 in a year with an extra pay date.

Because 26 doesn't divide evenly into 12 months, two months each year will have three paychecks instead of two. Many people don't budget for this, so it's worth marking on a calendar in advance — it's a pleasant surprise if you're expecting it, and a cash-flow gap if you're not.

Semimonthly: twice a month, 24 paychecks a year

Semimonthly pay means you're paid on two fixed dates each month — commonly the 15th and the last day of the month. That's always 24 pay periods a year, no matter how the calendar falls. Each paycheck is therefore slightly larger than a biweekly paycheck for the same annual salary, since the same yearly total is split across fewer payments.

Same annual salary, different-sized paychecks

Here's the part that trips people up: for the same $60,000 salary, biweekly pay works out to $2,307.69 per paycheck (26 payments), while semimonthly pay works out to $2,500.00 per paycheck (24 payments) — annual totals are identical, but the per-paycheck number is meaningfully different. If you're comparing two job offers with different pay schedules, always compare annualized take-home pay, not the number on a single paycheck.

Quick answers

Which pay schedule is more common in the US?

Biweekly pay is the most common private-sector pay schedule in the US, though semimonthly is also widely used, especially for salaried and government positions.

Do biweekly employees get paid more overall?

No — the annual salary is the same either way. Biweekly just splits it into 26 smaller payments instead of 24 slightly larger ones.

Why do I sometimes get three paychecks in one month?

Biweekly pay produces 26 payments a year, which doesn't divide evenly into 12 months. About twice a year, that extra half-period lands as a third paycheck in a single calendar month.

Does overtime work differently on each schedule?

The schedule itself doesn't change overtime rules — those are set by federal and state/provincial law based on hours worked in a workweek. Biweekly and semimonthly schedules simply differ in when that pay is issued.
