Biweekly vs. Semi-Monthly Pay: Which Is Better?

Biweekly vs. semi-monthly at a glance

Biweekly pay means a paycheck every other week, so 26 a year. Semi-monthly pay means two fixed dates a month, usually the 15th and the last day, so 24 a year.

Both pay the same yearly total for the same yearly salary. What changes is the size of each check, the number of checks, and how simple overtime is to calculate.

What each pay schedule means

Biweekly means once every two weeks. Payroll runs on the same weekday, for example every other Friday. That is 52 weeks divided by 2, so 26 paydays in a normal year.

Semi-monthly means twice a month on set dates, such as the 15th and the last day of the month. That is 12 months times 2, so exactly 24 paydays. When the date lands on a weekend or holiday, employers usually pay on the business day before.

Why people mix them up. The word bimonthly can mean twice a month or once every two months, which is why payroll teams avoid it. If a job post says “paid bimonthly”, ask which one they mean. Also, biweekly and semi-weekly are not the same: semi-weekly means twice a week.

How much is each paycheck?

Divide the yearly salary by the number of paychecks. A $60,000 salary is $2,307.69 biweekly and $2,500.00 semi-monthly, before taxes.

Gross pay only. Your take-home depends on tax withholding and deductions. For other pay periods, use the annual salary calculator.

A semi-monthly check looks bigger, but you are not earning more. You get 24 larger checks instead of 26 smaller ones, so the $192.31 difference per check on a $60,000 salary is just the same money cut into fewer slices.

The 27-payday year: what happens in 2027

A year has 52 weeks and one extra day (two in a leap year). Because of that leftover day, some years fit 27 biweekly paydays instead of 26. In 2027, any biweekly schedule that pays on Friday, January 1 gets 27 paydays, ending on Friday, December 31. Three months then have three paychecks: January, July and December.

What a 27th paycheck means for you

• Hourly workers: you are paid for hours worked, so the total for the year follows your hours. The extra check is not a bonus.
• Salaried workers: employers handle it in two ways. Some keep paying salary divided by 26, which makes the calendar-year total slightly higher. Others divide by 27 so the yearly total stays the same. Ask payroll which one your company uses.
• Budgeting: if you pay rent on the 1st, the months with three paychecks are your breathing room. Plan the third check for savings or debt, not the monthly budget.

Semi-monthly never has this issue, which is one reason salaried teams like it.

Semi-monthly hours change from check to check

A biweekly period is always exactly two workweeks, so a full-time employee works 80 hours in each. A semi-monthly period can have 10 to 12 weekdays. That swings an hourly worker’s paycheck. We counted weekdays (at 8 hours each, holidays ignored) for every semi-monthly period in 2027.

Overtime: the pay period does not decide it, the workweek does

Federal overtime is counted per workweek, a fixed, recurring period of 168 hours (seven days in a row). The pay period only decides when the overtime is paid.

This is where employers and employees most often get confused. You cannot average hours across two weeks, so “80 hours in a biweekly period” is not the overtime rule for most jobs. (Hospitals and care homes that use the special “8 and 80” system are the exception. See our guide to 8 and 80 overtime.)

Under 29 CFR 778.106, overtime is due on the regular payday for the pay period in which the workweek ends. If your workweek straddles two pay periods, the overtime lands in the second one.

A worked example

Workweek: Sunday Oct 11 to Saturday Oct 17, 2026. Hourly rate: $20. The employee works Monday to Friday, 9 hours a day, 45 hours total. Pay periods are semi-monthly, so the 1st–15th ends on Thursday Oct 15.

Period 1 shows no overtime even though the week is already at 36 hours. Overtime appears only in period 2, because the workweek ends on Oct 17. Our guide to workweeks that cross two pay periods and the workweek boundary checker walk through more cases.

Why this matters for the choice: a biweekly schedule that starts on the first day of the workweek keeps every workweek inside one pay period. Semi-monthly dates ignore the workweek, so some weeks always straddle two checks and payroll needs more care.

Does the law decide your pay schedule?

Federal law does not set how often you are paid. States do, and the rules differ.

This is a short list of states we checked, not a full table, and rules have exceptions for different job types and for exempt staff. The U.S. Department of Labor keeps a state-by-state payday table (a 2021 archive; confirm with the state agency before acting).

Pros and cons for employees and employers

Which is better?

For hourly and shift workers, biweekly is usually cleaner because the hours per period do not swing and overtime lines up with whole workweeks. For salaried office staff, semi-monthly is usually easier because each check is the same and falls on the same dates as rent and bills. Many small employers pick one for the whole company to keep payroll simple, and your state may limit the choice.

Can an employer change the pay schedule?

Federal law does not say. Many states require advance notice or approval before a change, so check your state labor department. In practice a switch creates a transition paycheck, for example a short or long period, which can look like a smaller check once. Ask payroll for the exact dates and for written notice.
