Semi-Monthly vs Biweekly Payroll: Which to Choose?

How often to pay employees may seem like an easy payroll decision. Choosing between semi-monthly and biweekly payroll can affect paycheck amounts, payroll processing, time tracking, cash flow planning, and how employees manage their income. Although biweekly and semi-monthly schedules both result in employees being paid regularly, they differ in important ways. 

There is no single best or universally correct payroll schedule. Many factors should be considered, including the timekeeping process, employee expectations, the nature of the workforce, and the payroll department’s processing workload.

Semi-Monthly vs Biweekly Payroll: The Quick Difference  

The easiest way to compare the two schedules is to look at how each one works.

This is general advice; these are not hard-and-fast rules. A company can use either of these schedules for salaried or hourly employees.

Choose whichever option best fits your workforce scheduling and payroll processing.

What Is Semi-Monthly Payroll?  

Semi-monthly payroll means employees are paid twice a month.

Paydays are commonly scheduled for the 15th and last day of the month.

For salaried employees, this is straightforward because it is easy to divide their annual salary into 24 paychecks.

If you want an explanation of the individual pay periods, see our  semi-monthly pay guide 

What Is Biweekly Payroll? 

Biweekly payroll means paying employees every two weeks.

With a standard biweekly payroll system, there are typically 26 paychecks per year.

Each pay period is 14 days long.

When the calendar does not align perfectly, there may be 27 paychecks in a year.
For more information, see our biweekly pay guide.

24 vs 26 Paychecks: What’s the Difference?

Biweekly pay does not mean employees earn more overall; annual pay is the same either way.  

Take an employee earning $60,000 a year.

Under a semi-monthly payroll system:
$60,000 ÷ 24 = $2,500

Under a biweekly payroll system:
$60,000 ÷ 26 = $2,307.69

In this case, each biweekly paycheck is smaller, but the employee receives two additional regular paychecks during a typical year.

The annual income remains the same: $60,000.

86.67 vs 80 Hours: Why the Math Matters  

Understanding the difference is useful when analyzing payroll schedules for hourly employees.

A 40-hour workweek for 52 weeks equals:
40 x 52 = 2,080 hours 

This results in:
2,080 / 26 = 80 hours per paycheck in a 26-pay biweekly system

or

2,080 / 24 = 86.67 hours in a 24-pay semi-monthly system.

The use of the word “average” is important.

A semi-monthly pay period does not have exactly 86.67 working hours every time. Actual working hours can be longer or shorter because semi-monthly pay periods are fixed based on calendar dates.

A biweekly pay period, by contrast, is always 14 days.

This makes 80 scheduled hours a straightforward baseline for a full-time employee working 40 hours per week. 

Working 80 hours is not a guarantee of no overtime. According to the U.S. Department of Labor, non-exempt employees earn overtime for hours worked beyond 40 in a single workweek.  An employee who works 45 hours in one week and 35 in the following week still accrues 5 hours of overtime.

Semi-Monthly Payroll: Pros and Cons  

Semi-monthly payroll can be a good fit for businesses that prefer fixed calendar paydays and monthly financial planning. 

Pros of Semi-Monthly Payroll 

• Fixed dates on calendars. Employees generally know which calendar dates they will be paid.
• Clear salary calculations. An annual salary can be distributed as 24 equal paychecks.
• Reduced payroll frequency.  Companies run payroll only 24 times a year.
• Easy monthly budgeting. Payroll runs twice each calendar month, so costs line up with monthly budgets.
• Often convenient for salaried staff. Fixed pay dates can make the schedule easy to manage.

Cons of Semi-Monthly Payroll

• Pay periods vary in length. The number of days between paydays is not always the same.
• Hourly calculations require more attention. Actual hours worked need to be tracked rather than assuming a fixed number of hours in every pay period.
• Overtime can be misunderstood. The payroll period does not replace the employer’s defined workweek for overtime purposes.
• Holiday and weekend paydays need planning. Companies should have a consistent policy for handling paydays that fall on non-business days.

Biweekly Payroll: Pros and Cons

Biweekly payroll provides a consistent two-week rhythm, which can be useful for businesses that rely heavily on time tracking.

Pros of Biweekly Payroll

• Consistent pay periods. Each regular period covers 14 days.
• Convenient for hourly employees. A standard 40-hour schedule produces 80 scheduled hours over two weeks.
• Predictable weekdays. Employees generally receive their paycheck on the same weekday every two weeks.
• Fits timekeeping naturally. Two-week periods can work well with timesheets and attendance records.
• More frequent paychecks. Employees generally receive 26 regular paychecks instead of 24.

Cons of Biweekly Payroll

• More payroll runs. Businesses generally process payroll 26 times in a typical year.
• Three-paycheck months. Some months will have three paydays, which requires cash-flow planning.
• Paydays move through the calendar. Employees do not receive their checks on the same numbered dates each month.
• Smaller individual salary payments. An annual salary is divided across 26 payments instead of 24.

Hourly vs Salaried Employees: Which Schedule Fits?

Biweekly payroll often has a distinct advantage over semi-monthly payroll for businesses with a large hourly workforce.

The first reason is predictability.

Each biweekly pay period covers exactly two weeks. As a result, hourly employees can easily correlate their time entries to payroll, and managers have a consistent timeframe to validate hours worked.

Although semi-monthly payroll can work for hourly employees, its pay periods are tied to calendar dates rather than a consistent two-week cycle. 

The company’s payroll system and processes should guide the pay schedule decision, rather than assuming that one system is better for salaried staff based solely on convenience.

What About the Two Extra Biweekly Paychecks?  

The 26-paycheck structure of biweekly payroll can require more careful annual cash-flow planning. 

Employees paid biweekly receive 26 paychecks in a year, so two months will typically contain three paychecks instead of two. However, employers must take into account the date on which the payroll cost is incurred.

To determine the best payroll schedule, businesses must consider the entire calendar.

WebWork’s pay period calculator allows users to compare the frequency of payroll, pay periods, hours, paycheck amounts, and payroll dates.

Rather than simply looking at “24 versus 26,” scheduling managers can see how each system impacts the schedule for an entire year.

How Does Time Tracking Fit Into the Decision?

Accurate payroll requires more than simply setting a pay frequency.

Payroll teams with hourly employees need a robust timekeeping system, as they must rely on precise records of when employees worked and how many hours they worked.

Incomplete records mean payroll issues will not disappear just because you switch from semi-monthly to biweekly pay.

A good timekeeping system should help with:

• Reviewing hours worked
• Identifying missing time
• Tracking overtime
• Comparing planned and actual hours worked
• Preparing payroll records

When a payroll system supports this level of tracking, payroll accuracy improves.

WebWork’s Employee Payroll Tracker can help businesses organize employee hours and payroll-related information.

The important question is not simply:

“When do we pay employees?”

It is also:

“Can we reliably produce the information needed to pay them accurately?

Semi-Monthly vs Biweekly Payroll: Which Should You Choose? 

The best choice depends on how your business operates.

Choose Semi-Monthly If:  

• Most of your workforce is salaried.
• Employees plan their budgets based on predictable pay dates.
• You prefer 24 payroll cycles a year.
• Semi-monthly pay is already processed effectively through your payroll system.

Choose Biweekly If:

• You have a large hourly workforce.
• Employees typically maintain consistent work schedules.
• You want every payroll period to cover two weeks.
• Accurate time tracking is very important for payroll.
• Employees prefer to be paid every two weeks.

Keep Your Current Schedule If:

• Your payroll system functions well as it is.
• Employees strongly prefer the existing pay cycle.
• Changing the schedules would create unnecessary administrative work.
• There is no compelling business reason to make a change.

Questions to Ask Before Changing Payroll Frequency

Before choosing a payroll schedule, consider the practical side of the decision.

How Many Employees Are Hourly?

Some hourly employees will find a biweekly pay schedule beneficial, especially if their hours and timekeeping are consistent on a two-week cycle.
A fixed semi-monthly payday can be convenient for salaried employees.

How Does Your Timekeeping Process Work? 

Consider how easily your team can review hours, approve timesheets, and identify overtime.

A payroll schedule should complement your existing timekeeping system, whether it is already in place or planned.

How Will Employees Respond? 

The frequency of payroll is a concern for employees.

Employees will receive different amounts on their paychecks  and will have different paydays  when the payroll frequency changes from semi-monthly to biweekly, even though their annual salary remains the same.

These changes must be explained to employees before the change is implemented.

What Does the Annual Payroll Calendar Look Like? 

List the actual paydays.

Look for three-paycheck months, weekends, holidays, and the change from one payroll schedule to another.

Semi-Monthly vs Biweekly Payroll: Side-by-Side Decision 

The best option is the schedule that aligns most closely with the company’s workforce and payroll processes.

Final Thoughts

Semi-monthly and biweekly payrolls perform the same basic functions, but in different ways. Semi-monthly payroll is aligned with the calendar. Employees are paid 24 times a year, on fixed calendar dates. Biweekly payroll is based on a two-week cycle. Employees are paid 26 times in a typical year, with each pay period spanning 14 days.

For a business with predominantly salaried employees, fixed semi-monthly calendar dates and monthly financial planning may make semi-monthly payroll the better choice. For a business with many hourly employees, fixed two-week payroll periods and the integration of time tracking and payroll may make biweekly payroll a better fit. When considering a change, examine the workforce, timekeeping system, overtime arrangements, cash flow, payroll workload, and employee needs.

The optimal payroll schedule for a business is one that the business can manage consistently and accurately, keeps payroll simple, and does not create additional behind-the-scenes administrative burdens.

Frequently Asked Questions

Is semi-monthly or biweekly payroll better? 

Both payment schedules have their pros and cons. On a semi-monthly basis, a business’s paydays may be more fixed, whereas paychecks may be more evenly distributed every 14 days with a biweekly payment schedule.

Do employees make more money with biweekly pay?

No. If a worker is salaried, the annual salary is the same whether payroll is semi-monthly or biweekly. Biweekly payroll spreads the salary across 26 paychecks instead of 24, so each paycheck is smaller.

How many paychecks do employees get with semi-monthly and biweekly payroll?

Semi-monthly payroll provides 24 paychecks per year. With biweekly payroll, there are 26 pay cycles, but some calendar years with 27 paychecks are possible. 

Is biweekly payroll better for hourly employees?

Because a biweekly pay period is always the same duration (two weeks), employees have a consistent pay cycle on which they can track and manage their pay. However, even if a business adopts a semi-monthly payroll system, this approach can still work for hourly employees.

Does an 80-hour biweekly pay period mean overtime starts after 80 hours?

No. Overtime hours are generally determined by hours worked by covered non-exempt employees in a single workweek, not by the total hours in a biweekly pay period.
