Biweekly vs Semi-Monthly Pay: What Is the Difference?

Compare biweekly and semi-monthly pay schedules, how many paychecks you get, and how it affects budgeting.

Both schedules pay you regularly, but they split the year differently, and that changes your paycheck size and your budgeting.

Biweekly: every two weeks

You are paid every other week, usually on the same weekday, which gives 26 paychecks a year. In two months of the year you receive three paychecks instead of two. Hourly workers often have biweekly pay.

Semi-monthly: twice a month

You are paid on set dates, commonly the 15th and the last day of the month, which gives 24 paychecks a year. Each check is the same size, and the dates do not shift with the weekday. This is common for salaried employees.

Does it change how much you earn?

No. Annual pay is the same either way. A $65,000 salary pays $2,500 per biweekly check or about $2,708 per semi-monthly check. Semi-monthly checks are larger, but you get fewer of them.

Budgeting tips

On a biweekly schedule, many people budget on the two checks per month and treat the extra two checks a year as savings, debt payments, or a buffer. On a semi-monthly schedule, match large bills such as rent to the first check of the month. See how your frequency changes take-home pay in the paycheck calculator.

Weekly and monthly pay

Some employers pay weekly (52 checks) or monthly (12 checks). The math is the same: divide your annual take-home pay by the number of pay periods.
