What Is Semi Monthly Payroll vs. Bi Weekly — What's the Real Difference?

[Tremblay]

I always thought semi monthly payroll and bi weekly payroll were essentially the same thing since both mean "twice a month," but my payroll software treats them very differently. Can someone explain exactly what semi monthly payroll is, how many pay periods it creates per year, and how the pay dates are determined? I'm particularly confused about how semi monthly payroll handles overtime calculations when a workweek spans two different pay periods — does that create any complications?

Yes, payroll bi-weekly results in 27th pay period after every 11-12 years since there are 52 weeks and one (or two) days in a year. Managers can either get the annual pay of the salaried employees divided by 27 or keep the regular number of 26 periods which means that they offer the employees a bonus year.

Semi-monthly payroll pays employees twice per month (24 pay periods/year) on fixed dates like the 15th and 30th. Bi-weekly payroll pays every two weeks (26 pay periods/year), typically on the same weekday.

The real difference is consistency: semi-monthly dates vary by weekday and can complicate overtime, while bi-weekly is more predictable and easier for hourly wage calculations.

Semi monthly payroll typically means you're paid on specific dates, usually the 15th and 30th of each month, which results in 24 pay periods per year. This can get a bit tricky when calculating overtime, especially if a workweek spans two different pay periods. In that case, the overtime would need to be split between the two pay periods, which can be complicated. For example, if an employee works overtime on the last day of the month and the first few days of the next month, the overtime hours would need to be accounted for in both pay periods, which can be a challenge for payroll software to handle accurately.
