Weekly vs. Biweekly vs. Semimonthly Payroll

The pay frequency you choose changes how often your team gets paid, how much work each pay run takes, and how payroll lines up with your cash flow. Weekly, biweekly, and semimonthly are three of the most common schedules, and each one has tradeoffs that matter for a small business.

This guide compares weekly vs biweekly vs semimonthly payroll in plain language so you can pick the schedule that fits your team and your books. If you are newer to payroll altogether, it helps to start with our guide on payroll processing basics before you choose a frequency.

What Is Pay Frequency?

Pay frequency is how often you run payroll and pay your employees. It sets the number of pay periods in a year, the size of each paycheck, and the dates your team expects to be paid. The frequency does not change how much an employee earns in a year. It only changes how that annual amount is split into paychecks.

A salaried employee who earns $52,000 per year earns the same total whether they are paid weekly, biweekly, or semimonthly. What changes is the size of each check and the number of checks. More frequent pay means smaller checks and more pay runs. Less frequent pay means larger checks and fewer pay runs.

The Three Common Pay Frequencies

Weekly, biweekly, and semimonthly payroll each work a little differently. The table below shows how they compare on pay periods per year, pay date pattern, and who they tend to suit.

Weekly Payroll

Weekly payroll pays employees every week on the same weekday, which gives 52 pay periods in a year. It is the most frequent of the three options, so each paycheck is smaller and pay runs happen most often.

Weekly payroll suits businesses with hourly staff who value frequent pay, such as service crews and shift workers. Frequent pay helps employees cover weekly expenses and reduces the gap between work and wages. The tradeoff is that weekly payroll means more pay runs, more calculations, and more chances for data entry errors. For more on how that calculation works, see our guide on gross pay vs net pay.

Biweekly Payroll

Biweekly payroll pays employees every two weeks on the same weekday, which gives 26 pay periods in a year. It is one of the most common schedules because it is simple to run and easy for employees to budget around.

Because 26 pay periods do not divide evenly into 12 months, two months in the year have three biweekly pay periods instead of two. Those extra pay periods are normal, but they affect your monthly cash flow and your payroll budget. Biweekly payroll works well for businesses with a mix of hourly and salaried staff because each pay period is a clean two weeks of work.

Semimonthly Payroll

Semimonthly payroll pays employees twice a month on fixed dates, such as the 15th and the last day of the month, which gives 24 pay periods in a year. It always has two pay periods each month, so it lines up neatly with monthly bills, rent, and financial reporting.

Semimonthly payroll suits salaried staff well because the pay dates are predictable and the monthly totals are even. The tradeoff is that semimonthly pay periods do not line up with full weeks, so hourly payroll is harder to calculate. You have to track partial weeks and handle odd day counts.

Example: A Retail Store With Hourly Staff

Consider a small retail store with hourly staff paid $22 per hour. The owner runs payroll weekly so employees get paid every Friday for the hours they worked that week. In a week where an employee works 40 hours, their gross pay is $880 before withholdings.

Weekly payroll keeps the gap between work and wages short, which hourly staff tend to appreciate. The tradeoff is that the owner runs 52 pay periods a year, which is more processing work and more chances for data entry errors. The example shows why a business with hourly staff often picks a weekly schedule even though it means more pay runs.

Example: An Office With Salaried Staff

Take a small office with salaried staff paid $52,000 per year. The owner runs payroll semimonthly on the 15th and the last day of the month, which is 24 pay periods. Each employee's gross pay for each pay period is $2,166.67 before withholdings, which is the annual salary divided by 24.

Semimonthly payroll lines up neatly with the office's monthly bills and reporting, and the pay dates are predictable. The tradeoff is that the pay periods do not line up with full weeks, so if the office ever adds hourly staff, the day counts get harder to manage. The example shows why a business with salaried staff often picks a semimonthly schedule.

How to Choose the Right Pay Frequency

Choosing a pay frequency comes down to your staff, your cash flow, and how much payroll work each run takes. The right schedule is the one that balances what your team expects with what your books can support.

• Pick weekly payroll if you have hourly staff who value frequent pay and you can handle more pay runs.
• Pick biweekly payroll if you want a simple schedule that works for a mix of hourly and salaried staff.
• Pick semimonthly payroll if you have salaried staff and want pay dates that line up with monthly bills.
• Check your cash flow against each schedule, since more frequent pay means more frequent outflows.
• Confirm the schedule works for your payroll processing workload before you commit to it.

Whatever schedule you choose, the withholdings and net pay have to be right on every pay run. For more on how those lines fit together, see our guide on how payroll deductions work.

Common Pay Frequency Mistakes

• Confusing biweekly with semimonthly. Biweekly means every two weeks, which is 26 pay periods. Semimonthly means twice a month, which is 24 pay periods. They sound similar but produce different pay dates and a different number of pay periods in the year.
• Forgetting the extra biweekly pay periods. Two months in the year have three biweekly pay periods instead of two. If you budget monthly, those extra pay periods can catch you off guard. Plan for them so your cash flow stays steady.
• Running hourly payroll on a semimonthly schedule. Semimonthly pay periods do not line up with full weeks, so hourly payroll is harder to calculate. If you have hourly staff, a weekly or biweekly schedule is usually simpler and less error prone.
• Changing pay frequency without telling your team. Employees plan their budgets around pay dates. If you change the frequency, tell your team ahead of time and explain how it changes the size and timing of their checks.
• Not updating your payroll budget for the new schedule. Each frequency produces a different number of pay periods and a different monthly outflow. Update your payroll budget when you change schedules so your books reflect the real cost of payroll.

Getting Started

Weekly, biweekly, and semimonthly payroll each have tradeoffs. Weekly payroll pays often but means more pay runs. Biweekly payroll is simple and common. Semimonthly payroll lines up with monthly bills but is harder for hourly staff. The right schedule is the one that fits your team and your books, and the one you can run accurately every time.
