Semi-Monthly vs Biweekly Pay: What’s the Difference?
Semi-monthly means 24 paychecks a year (twice a month); biweekly means 26 (every two weeks). Here is how they differ and which states allow what.
Semi-monthly means 24 paychecks a year (twice a month); biweekly means 26 (every two weeks). Here is how they differ and which states allow what.
Semi-monthly pay happens twice a month — typically the 1st and 15th — giving 24 paychecks a year. Biweekly pay happens every two weeks, usually on the same weekday, giving 26 paychecks a year (27 in some years).
The practical differences: biweekly checks are more frequent and a fixed interval (easier for hourly payroll); semi-monthly is predictable by calendar date but pay amounts vary if the employee is hourly. Both are legal in most states, though a few restrict semi-monthly to certain schedules. Check the state chart for your state.
