Pay Frequency: Weekly, Biweekly, Semimonthly, Monthly

Pay frequency is how often employees are paid. It changes the size of each paycheck, how benefit deductions are split and how payroll lines up with the workweek. The yearly total stays the same; the timing does not.

The four common schedules

Weekly: 52 paychecks a year

Employees are paid every week, usually on the same weekday. Weekly pay is common for hourly work in industries like construction and hospitality. Each pay period matches one workweek, which makes overtime easy to calculate and show on the stub.

Biweekly: usually 26 paychecks a year

Employees are paid every other week on the same weekday. This is one of the most common schedules in the US. Because 52 weeks divide evenly into 26 pairs but a year has 365 or 366 days, some calendar years contain 27 biweekly pay dates, depending on where the first pay date falls. Employers paying a fixed salary should plan for that year.

Semimonthly: 24 paychecks a year

Employees are paid twice a month on fixed dates, often the 15th and the last day of the month. Pay dates fall on different weekdays and move when they land on a weekend or holiday. Semimonthly is popular for salaried staff because each paycheck is the same size and monthly benefit premiums split neatly in two.

Monthly: 12 paychecks a year

Employees are paid once a month. It is the simplest to run but means the longest wait between paychecks, and some states restrict monthly pay for certain workers.

The same salary on each schedule

For example, a $52,000 annual salary works out to:

• Weekly: $52,000 / 52 = $1,000
• Biweekly: $52,000 / 26 = $2,000
• Semimonthly: $52,000 / 24 = about $2,166.67
• Monthly: $52,000 / 12 = about $4,333.33

A common mix-up is treating biweekly and semimonthly as the same. Biweekly pay has two extra paychecks a year, so each one is smaller.

How frequency affects the pay stub

Withholding

Federal income tax withholding tables in IRS Publication 15-T are built for each pay frequency. The calculation annualizes the period's wages, figures the tax, then divides back. If the frequency on the stub is wrong, withholding will be wrong. See how federal withholding works.

Benefit deductions

Monthly costs have to be spread over paychecks. For example, a $200 monthly health premium is $100 per semimonthly paycheck, but on a biweekly schedule it is either about $92.31 per paycheck ($200 x 12 / 26) or $100 on two paychecks a month with nothing taken on the third-paycheck months. Either approach works if it is applied consistently.

Overtime

Under federal law, overtime for non-exempt employees is based on hours over 40 in a workweek, whatever the pay frequency. On semimonthly and monthly schedules the pay period does not line up with workweeks, so a workweek can straddle two pay periods and overtime may show up on the stub after the period in which it was worked. Our guide to hourly vs salaried pay stubs covers the overtime rules.

Year-to-date totals

More frequent pay means YTD grows in smaller steps. The annual total is the same, but a weekly employee's stub after three months has about 13 periods in it, while a monthly employee's has three. See YTD totals explained.

State pay frequency rules

Federal law does not set a required pay frequency, but many states do. Some require at least semimonthly pay for most workers, others set different rules by type of work or allow monthly pay for certain salaried roles. Before choosing or changing a schedule, employers should check with their state labor department.

Choosing a schedule as an employer

• Cost and effort: more pay runs mean more processing work and, with some providers, more fees.
• Workforce: hourly teams often prefer weekly or biweekly pay; salaried teams are often on semimonthly.
• Budgeting for employees: shorter gaps between paychecks can make budgeting easier for workers.
• Consistency: changing frequency mid-year is possible but requires care with withholding, deductions and YTD tracking.

Setting frequency on a pay stub

When you create a pay stub in PayStubNest, choose the pay frequency first. The calculator uses it to split salary, apply the right withholding and carry YTD totals across a series of stubs on that schedule. The FAQ covers templates and downloads, and how to read a pay stub explains each section of the result.
