Differences Between Semimonthly and Biweekly Pay Schedules

What Is a Semimonthly Pay Schedule?

A semimonthly pay schedule provides two paychecks each month, resulting in 24 paychecks per year.

Common payment dates include:

• The 1st and 15th
• The 15th and final day of the month
• The 5th and 20th

The payment dates remain consistent, but the weekday changes. For example, the 15th may fall on a Monday one month and a Thursday the next.

For salaried employees, employers commonly divide annual pay into 24 equal amounts.

An employee earning $60,000 per year would receive:

$60,000 ÷ 24 = $2,500 in gross pay per paycheck

Taxes and other deductions would reduce the employee’s take-home pay.

What Is a Biweekly Pay Schedule?

A biweekly pay schedule provides one paycheck every two weeks, usually on the same weekday.

For example, employees may be paid every other Friday.

A biweekly schedule normally produces 26 paychecks per year. Most months contain two paydays, while two months contain three.

An employee earning $60,000 per year would receive:

$60,000 ÷ 26 = approximately $2,307.69 in gross pay per paycheck

The employee receives smaller individual paychecks than under a semimonthly schedule, but receives two additional checks during the year.

Main Difference Between Semimonthly and Biweekly Pay

The main difference is the number of pay periods:

• Semimonthly: 24 pay periods per year
• Biweekly: 26 pay periods per year

Other differences include:

• Semimonthly pay occurs on fixed calendar dates.
• Biweekly pay occurs on the same weekday every two weeks.
• Semimonthly paychecks are larger for salaried employees.
• Biweekly employees receive two more paychecks per year.
• Biweekly periods align with complete workweeks.
• Semimonthly periods vary in length.
• Semimonthly payroll requires two fewer annual payroll runs.

The total annual salary remains the same when only the frequency changes.

Semimonthly Pay Example

Suppose an employee earns $72,000 per year and receives semimonthly pay.

$72,000 ÷ 24 = $3,000 gross pay per paycheck

The employee receives $3,000 twice each month before taxes and deductions.

If the company pays on the 15th and final day of each month, the exact days of the week vary. The company may adjust payment when a scheduled payday falls on a holiday or weekend.

Biweekly Pay Example

Suppose the same employee earns $72,000 per year and receives biweekly pay.

$72,000 ÷ 26 = approximately $2,769.23 gross pay per paycheck

The employee typically receives two checks per month, but receives three checks during two months of the year.

The annual gross pay remains $72,000.

Differences in Paycheck Timing

Semimonthly timing

Semimonthly employees can plan around two fixed dates. This may make it easier to coordinate payments for rent, loans and utilities.

However, the weekday varies, and the employer must decide how to handle weekends and holidays.

Biweekly timing

Biweekly employees know the weekday on which they are normally paid. This pattern can be easy to remember, but the calendar date changes.

The schedule does not always align neatly with monthly bills.

Differences in Paycheck Size

For salaried employees, semimonthly checks are larger because annual pay is divided by 24 rather than 26.

Biweekly checks are smaller, but there are two more paydays.

Neither schedule automatically increases or decreases annual compensation.

Differences for Hourly Employees

Biweekly payroll often works more naturally for hourly employees because each period contains two complete seven-day workweeks.

This can simplify:

• Timesheet collection
• Regular-hour calculations
• Overtime calculations
• Weekly attendance records
• Shift reporting

Semimonthly pay periods may begin or end in the middle of a workweek. Payroll employees must track legally defined workweeks separately from the payroll period.

Applicable wage and overtime laws still apply regardless of the employer’s chosen schedule.

Differences in Overtime Calculations

Overtime is often calculated according to a defined workweek rather than the total number of hours in a pay period.

Biweekly payroll contains two complete workweeks, making overtime easier to identify.

Semimonthly periods can contain portions of three workweeks. Employers may need more careful systems to ensure overtime hours are included in the correct paycheck.

Differences in Benefit Deductions

Benefits such as health insurance are commonly priced monthly.

With semimonthly payroll, a monthly deduction can be divided evenly between two paychecks.

For example:

$400 monthly insurance deduction ÷ 2 = $200 per paycheck

With biweekly payroll, the employer must decide how to distribute deductions across 26 checks. It may:

• Divide the annual deduction by 26
• Take deductions from only 24 checks
• Use another documented method

Employees should receive a clear explanation of the company’s approach.

Advantages of Semimonthly Pay

Fixed payment dates

Employees can expect deposits on two specific dates each month.

Larger individual paychecks

Salaried employees receive 24 larger checks rather than 26 smaller ones.

Consistent monthly payroll count

Employers process two payrolls every month without three-paycheck periods.

Easier benefit deductions

Monthly insurance and benefit costs can be divided evenly.

Fewer payroll runs

Employers complete 24 annual payrolls, potentially reducing administrative time and processing fees.

Disadvantages of Semimonthly Pay

Varying weekdays

Paydays do not consistently fall on the same day of the week.

Holiday and weekend adjustments

Employers need a policy for moving paydays that fall on nonbusiness days.

Unequal period lengths

Semimonthly periods can contain different numbers of calendar and working days.

More complicated hourly payroll

The periods do not align with complete workweeks, making overtime and timesheet calculations more complex.

Longer gaps between some paydays

Depending on the dates, employees may occasionally wait slightly longer between checks.

Advantages of Biweekly Pay

Consistent weekday

Employees usually receive pay on the same weekday every two weeks.

Alignment with workweeks

Each pay period includes two complete seven-day workweeks.

Easier overtime calculations

Employers can calculate weekly overtime within the same pay period.

Two additional paychecks

Employees receive 26 checks rather than 24. The two three-paycheck months can provide opportunities to save or reduce debt.

Familiarity

Many employees are already accustomed to an every-other-week schedule.

Disadvantages of Biweekly Pay

Smaller paychecks

Salaried employees receive smaller amounts per check because annual pay is divided into 26 payments.

Three-paycheck months

Employers must plan cash flow for two months containing an additional payroll.

More payroll runs

The company processes two more payrolls per year than it would under a semimonthly schedule.

Potentially higher costs

Payroll providers may charge per payroll run, increasing annual expenses.

More complicated monthly deductions

Employers need a consistent method for distributing monthly benefit deductions across 26 checks.

Which Schedule Is Better for Employees?

The answer depends on individual budgeting preferences.

Semimonthly pay may suit employees who:

• Plan around fixed monthly bills
• Prefer larger individual paychecks
• Budget according to calendar months
• Want deductions divided into two consistent amounts

Biweekly pay may suit employees who:

• Prefer being paid on the same weekday
• Budget in two-week periods
• Value two additional annual paychecks
• Work variable or overtime hours

The annual salary is normally unaffected by the choice.

Which Schedule Is Better for Employers?

Semimonthly pay may be easier when:

• Most employees receive fixed salaries
• Benefits are calculated monthly
• The company wants fewer payroll runs
• Monthly cash-flow consistency is important

Biweekly pay may be easier when:

• Many employees receive hourly wages
• Overtime is common
• Timesheets follow weekly cycles
• Employees prefer every-other-week pay

Employers should also consider payroll software, provider fees and applicable wage-payment laws.

How To Budget With Semimonthly Pay

Assign recurring expenses to each of the two monthly checks.

For example:

First paycheck:

• Rent or mortgage
• Insurance
• Utilities
• Transportation

Second paycheck:

• Food
• Debt payments
• Savings
• Subscriptions

Keep a small cash buffer in case a scheduled payday moves because of a holiday or weekend.

How To Budget With Biweekly Pay

Build your normal monthly budget around two checks. Avoid depending on a third paycheck for recurring expenses because it occurs only twice per year.

Possible uses for additional checks include:

• Emergency savings
• Credit card payments
• Retirement contributions
• Annual insurance
• Vehicle maintenance
• Education expenses
• Planned travel

Review the actual deductions before allocating the check.

How Employers Can Communicate a Pay Schedule

Employers should tell employees:

• The payroll frequency
• The normal payment day or dates
• The dates each pay period covers
• How weekends and holidays affect payment
• When timesheets are due
• How overtime is calculated
• How benefit deductions are divided
• Who can answer payroll questions

Provide a payroll calendar during onboarding and whenever the schedule changes.

Frequently Asked Questions

Is semimonthly the same as twice a month?

Yes. Semimonthly payroll provides two paychecks per month, normally on fixed calendar dates. It produces 24 pay periods per year.

Is biweekly the same as twice a month?

No. Biweekly means every two weeks. It normally produces 26 paychecks per year, while twice-monthly or semimonthly pay produces 24.

Do biweekly employees earn more?

Not because of the payroll schedule alone. Salaried employees usually receive the same annual pay divided across 26 smaller checks instead of 24 larger checks.

Why do some biweekly months have three paychecks?

A biweekly schedule creates a payday every 14 days. Because this results in 26 annual paydays, two calendar months generally contain three paychecks.
