If you’re paid biweekly, you receive 26 paychecks in a typical year. That’s because biweekly means every two weeks, and 52 weeks divided by 2 equals 26 pay periods. However, roughly once every 11 years, the calendar lines up to produce 27 pay periods instead, which can affect your budget, your per-check amount, and even your payroll deductions.
Why It’s 26, Not 24
People sometimes confuse biweekly (every two weeks) with semimonthly (twice a month). Semimonthly pay gives you exactly 24 paychecks per year, typically on set dates like the 1st and 15th. Biweekly pay gives you a check every 14 days regardless of the calendar date, which adds up to 26 checks because most years have 365 days, not a clean multiple of 14.
To see how this works with real numbers: if your annual salary is $100,000 on a biweekly schedule, each gross paycheck is $100,000 divided by 26, or about $3,846.15. That per-check amount is lower than what you’d see on a semimonthly schedule ($4,166.67), but you’re getting two extra checks over the course of the year to make up the difference.
The 27th Paycheck
Every year ends with one extra day beyond 52 full weeks (two extra days in a leap year). Those leftover days gradually shift your payday forward on the calendar. After about 11 years, according to the Government Finance Officers Association, those extra days accumulate enough to create a full additional pay period, giving you 27 paychecks instead of 26.
Whether the 27th paycheck falls in a given year depends on what day of the week your employer’s pay cycle starts and how banking holidays affect the schedule. For example, if a payday lands on January 1, your employer may move it to December 31 of the previous year, which could shift a 27-paycheck year forward or backward by a full calendar year. The exact timing varies by employer, so check your company’s payroll calendar to see which years affect you.
Two “Three-Paycheck” Months Each Year
Even in a standard 26-paycheck year, two calendar months will contain three paydays instead of the usual two. Which months those are depends on your specific pay dates. If you budget based on receiving two checks per month, these three-check months feel like a bonus, even though your annual income hasn’t changed.
This is a useful budgeting opportunity. Since most monthly bills (rent, utilities, subscriptions) are sized around two paychecks per month, the third check in those months is money you can direct toward savings, extra debt payments, or building an emergency fund without adjusting your regular spending.
How Extra Checks Affect Your Deductions
Your payroll deductions may not work the same way on every check, especially during three-paycheck months. Many employers handle it this way:
- Flat-dollar deductions like health insurance premiums, transit benefits, and credit union payments are typically split across only two paychecks per month. The third paycheck in a three-check month often skips these deductions entirely, sometimes called a benefits “holiday.” That means your take-home pay on that third check may be noticeably higher than usual.
- Percentage-based deductions like a 401(k) contribution set as a percentage of your pay are taken from every single paycheck, including the third one in a three-check month.
- Garnishments set as flat dollar amounts are also taken from every check, with no holiday.
If your employer does skip benefit deductions on the third paycheck, you’ll typically see this happen twice a year. It doesn’t change what you owe for the year; the same total amount is spread across 24 deductions instead of 26.
How to Find Your Pay Dates
Most employers publish a payroll calendar at the beginning of each year, either through your HR portal or your payroll system. This calendar shows every pay date for the year and makes it easy to spot the three-check months. If you’re trying to plan your budget, map those dates against your monthly bills so you know exactly when the extra check arrives and can decide in advance how to use it.
For quick reference: count 26 paychecks as your baseline for any normal year. If your employer’s payroll calendar shows 27, you’ll know it’s one of those roughly once-a-decade years where the calendar math works in your favor.
