Biweekly pay works on a fixed 14-day cycle: your employer pays you every other week on the same weekday, most often Friday, producing 26 paychecks over the year. Your annual earnings are split into equal gross amounts before taxes and deductions come out, so each check reflects two weeks of work rather than a fraction of a month.
The 14-Day Cycle
A biweekly payroll repeats every two weeks on a recurring payday the employer selects. Because 14 × 26 = 364, the schedule runs one day short of a full year (two days in a leap year), and that leftover day slowly shifts the calendar alignment.
Federal law does not set a pay frequency. The Fair Labor Standards Act requires employers to track hours worked and wages paid, but it leaves how often you get paid to the employer or to state law.1Office of the Law Revision Counsel. 29 U.S. Code 211 – Collection of Data State rules fill the gap, and the minimum required frequency ranges from weekly to monthly depending on the state and the type of employee.
When a payday falls on a federal bank holiday, the ACH network that moves direct deposits does not run. Most employers push payroll a day earlier so the funds arrive on the last business day before the holiday.
How Each Paycheck Is Calculated
Salaried Workers
If you’re on a salary, gross biweekly pay is your annual salary divided by 26. Someone earning $52,000 a year sees $2,000 gross on each stub before taxes and other deductions, and that number stays the same period after period regardless of how many working days the two-week window happens to contain.
Hourly Workers
Hourly employees multiply their rate by the hours actually worked in the 14 days. Two 40-hour weeks equal 80 hours per period. At $25 an hour that comes to $2,000 gross, but the total moves up or down whenever real hours differ from 80, whether from time off, a short week, or overtime.
Overtime on a Biweekly Schedule
Overtime is where biweekly pay most often gets misread. Under federal law, overtime is owed when you exceed 40 hours in a single workweek, not 80 hours across the two-week pay period.2Office of the Law Revision Counsel. 29 USC 207 – Maximum Hours Each workweek stands alone, and averaging hours across two or more weeks isn’t allowed.3U.S. Department of Labor. Fact Sheet 23 – Overtime Pay Requirements of the FLSA
Say you work 50 hours the first week of a pay period and 30 hours the second. Your total is 80, the same as a standard period, but you’re still owed 10 hours of overtime at one-and-a-half times your regular rate for the first week. The lighter second week cannot cancel out the heavier first one.4U.S. Department of Labor. FLSA Overtime Calculator Advisor – General Principles Pay frequency doesn’t change this. Weekly, biweekly, or monthly, the 40-hour workweek threshold applies the same way.
What Comes Out of Each Check
Federal Income Tax
Your employer withholds federal income tax from each paycheck based on the Form W-4 you filed, including filing status, dependents, and any additional withholding you requested.5Internal Revenue Service. Publication 15 (2026), (Circular E), Employer’s Tax Guide The IRS publishes withholding tables specifically for biweekly pay periods, and your employer’s payroll system uses those to set the exact amount.
Social Security and Medicare
The Federal Insurance Contributions Act takes 6.2% of each check for Social Security and 1.45% for Medicare, with your employer matching both.6Internal Revenue Service. Topic No. 751, Social Security and Medicare Withholding Rates On a $2,000 biweekly check, that’s $124 for Social Security and $29 for Medicare, or $153 total.
Social Security tax stops for the rest of the year once your cumulative earnings pass the annual wage base, which is $184,500 in 2026.7Social Security Administration. Contribution and Benefit Base Medicare has no cap; the 1.45% keeps coming out of every dollar you earn.5Internal Revenue Service. Publication 15 (2026), (Circular E), Employer’s Tax Guide
Voluntary Deductions
After mandatory taxes, your employer subtracts the voluntary items you elected. Health, dental, and vision premiums and retirement contributions are the most common. For 2026, the employee 401(k) contribution limit is $24,500, with an additional $8,000 catch-up available if you’re 50 or older.8Internal Revenue Service. 401(k) Limit Increases to $24,500 for 2026 What’s left after everything is your net pay, the amount that actually reaches your bank account.
Three-Paycheck Months
Twenty-six paychecks don’t split evenly across 12 months, so two months each year contain three paydays rather than the usual two. Which months those are depends on where your employer’s calendar begins. If your first 2026 paycheck lands on January 2, the three-paycheck months are January and July. If it lands on January 9, they fall in May and October.
For salaried workers, these extra checks don’t mean extra annual pay. The total is unchanged. But they can affect the size of a specific deposit. Many employers spread annual insurance premiums across only 24 of the 26 paychecks, taking deductions from the first two paydays each month and skipping the third. That third check, sometimes called a benefits holiday, arrives without the usual insurance deductions and lands noticeably larger.
Percentage-based deductions behave differently. A 401(k) contribution set as a percentage of pay comes out of every check, including the third one, so your total annual contribution runs slightly higher than it would on a 24-period schedule at the same percentage.
The 27th Paycheck
Every 11 or 12 years, the leftover day that piles up each cycle pushes the calendar far enough that a 27th paycheck fits into the year. For an employer paying every other Friday starting January 2, 2026, the last check of the year can fall on December 31.
Not every biweekly employer hits this in the same year; it depends on the starting weekday of the cycle. When it does happen, employers usually take one of three approaches:
- Keep dividing the annual salary by 26 for each check, which means paying slightly more than the stated annual salary that year and correcting when the next 27-period year arrives.
- Divide the annual salary by 27 instead, which shrinks each check. A $52,000 salary comes out to roughly $1,925.93 per check rather than $2,000.
- Use a daily-rate method, multiplying the annual salary by 14/365, which produces a slightly lower per-check amount and naturally absorbs the extra period.
Benefit deductions may shift too. Some employers divide annual insurance costs by 27, and others continue deducting from only 26 checks and skip the 27th. If your per-check amount or deduction structure is going to change for a 27-period year, you should get advance notice, with the specifics governed by state labor law.
Biweekly Is Not Semi-Monthly
The two terms sound alike but produce different results. Biweekly pays every two weeks for 26 checks a year. Semi-monthly pays twice a month on fixed dates, commonly the 1st and 15th, for exactly 24 checks a year. The same annual salary split into more pieces means each biweekly check is smaller. An employee earning $52,000 receives about $2,000 per biweekly check ($52,000 ÷ 26) versus about $2,166.67 per semi-monthly check ($52,000 ÷ 24). The annual total is identical. The visible difference is in the rhythm: biweekly gives you two extra checks a year compared with semi-monthly, which is where the three-paycheck months come from.
