How many pay periods in a year
A biweekly payroll pays every 14 days, and 14 does not divide a calendar year evenly, so a biweekly year holds 26 pay dates in most years and 27 in some, and which one you get is decided by your own first pay date.
Dates are built and read in UTC, so the count does not move with your time zone or with a daylight saving change. Semimonthly and monthly schedules are anchored to the calendar, on the 15th and the last day of each month, so the date you enter does not change their count.

On this schedule the months with an extra check are January and July. Those are the months where the same salary arrives in 3 parts instead of 2, which is a cash-flow event, not a raise.
This schedule is anchored to the calendar rather than to a repeating interval, so every month carries the same number of checks and no month is an extra-check month.
What an extra paycheck year does to every check
A salary is an annual number. Spreading it across one more pay date makes every check of that year smaller. The card below prices that for whatever you have entered above.
This schedule is anchored to the calendar, so its period count never changes and there is no extra check year to price.
The gross gap is not an estimate, it is an identity. For a biweekly payroll, a salary divided by 26 minus the same salary divided by 27 is that salary divided by 702. On the worked example of $62,000 that is $88.32 a check, which is what the gross difference line reads before you change anything. The take-home gap is smaller, $74.07 on that same example, because the annual tax bill does not move when the divisor does. Tax is charged on the year, not on the check.
An employer facing an extra-check year picks one of two answers, and they are not the same deal for you. Re-dividing the salary keeps annual pay at $62,000 and shrinks every check by $74.07 in take-home terms. Leaving the per-check amount alone and paying the extra check anyway raises annual gross to $64,385, which is $2,385 more than the salary on the offer letter. Ask which one your payroll department has chosen before the year starts, because the first version arrives as a pay cut that nobody announced.
Weekly, biweekly, semimonthly and monthly on the same salary
One salary of $62,000, one state, four schedules. The period counts come from the generator above, not from a table.
| Schedule | Periods | Gross per check | Take home |
|---|---|---|---|
| Weekly | 52 | $1,192.31 | $999.94 |
| Biweekly | 26 | $2,384.62 | $1,999.88 |
| Semimonthly | 24 | $2,583.33 | $2,166.54 |
| Monthly | 12 | $5,166.67 | $4,333.08 |
Annual take-home is identical down every row. Only the size of the slice changes. That is the single most useful thing to know before you argue with payroll about a schedule change, and it is also why a bigger check is not a better one.
Semimonthly is not biweekly
Both get called twice a month. Only one of them is.
Semimonthly pay lands on two fixed calendar dates, here the 15th and the last day of the month, so it produces 24 periods every year without exception. Biweekly pay lands every 14 days, which drifts against the calendar and produces 26 periods in 2026 for a payroll that starts on Jan 2. On the worked example of $62,000 that is $2,583.33 gross a semimonthly check against $2,384.62 gross a biweekly one, a gap of $198.72 per check. In take-home the semimonthly check is $2,166.54 and the biweekly check is $1,999.88.
The biweekly worker is not paid less. They receive 2 more checks a year, each one smaller. Those extra checks land in months that already had 2, which is where the idea of a bonus month comes from. Nothing extra was earned. The calendar simply let 3 pay dates fall inside one month.
This matters for anything you time to a paycheck. A semimonthly worker knows both dates a year out. A biweekly worker does not, because in 2 months of 2026 that payroll pays a different number of times than in the other 10.
Why the count moves at all
26 fortnights is 364 days. So is 52 weeks. No calendar year is 364 days long. 2026 runs 365 days, which leaves 1 day over, and a leap year runs 366 days, which leaves 2. Those leftover days accumulate. Each year the first pay date of the year moves earlier by 1 day, or by 2 across a leap year, until it lands close enough to January the first that a 27th pay date fits inside the year.
That is the whole mechanism, and it is why the answer cannot be a table. The count turns on one fact no ranking page can know, the date your employer chose for the first payroll of the year. Two people at different companies, both biweekly, can get 26 and 27 in the same calendar year.
Weekly payrolls do the same thing one step faster. A payroll first paid on Jan 2, 2026 carries 52 weekly pay dates this year, and over the next 20 years it carries 53 in 2027, 2032, 2038, 2044. Change the start date by a single day and that list changes with it.
Payroll teams see this coming and often do not tell anyone. A 27 period year changes per-check benefit deductions as well as gross. Deductions that are quoted as a monthly premium are usually taken over 26 checks, so an extra check either gets skipped for deductions or every check carries slightly less. Both choices are defensible. Neither is obvious from a payslip.
Common questions
How many pay periods are in a year
A weekly schedule has 52 or 53 pay periods, biweekly has 26 or 27, semimonthly always has 24 and monthly always has 12, and for the two that vary the answer depends on your employer's first pay date of the year rather than on the calendar.
Which months have three paychecks
For a biweekly payroll first paid on Jan 2, 2026, they are January and July. Change the first pay date in the calculator and the months change with it. A 26 period year always has 2 such months, because 26 checks spread over 12 months leaves that many left over. A 27 period year has 3.
Does a 27th paycheck mean I am paid more
Only if your employer chose to pay it on top. If the annual salary is re-divided across 27 periods, annual pay stays at $62,000 and each check falls by $74.07 in take-home. If the per-check amount is held and the extra check is added, annual gross rises to $64,385. Same year, same calendar, two very different outcomes.
Is semi monthly the same as biweekly
No. Semimonthly is 24 fixed calendar dates a year, every year. Biweekly is a 14 day cycle, and on the worked example it produces 26 pay dates in 2026. On $62,000 the semimonthly check is $2,583.33 gross and the biweekly check is $2,384.62 gross.
Why does my employer say 26 when I count 27
Because 26 is the number the salary was built on, and 27 is the number of pay dates that happen to fall inside one particular calendar year. Counting the dates on your own calendar is the way to settle which year you are in.
What this leaves out
The period counts are arithmetic and hold for any employer paying on a fixed cycle. The money figures are an estimate, not tax advice. They exclude pre-tax deductions such as a 401(k) or a health premium, local and city taxes, credits, garnishments, and anything specific to your employer's payroll. For states with graduated brackets the state portion is carried as one labelled effective rate, so treat that part as an approximation.
The generator also assumes your employer never shifts a pay date. Real payrolls move a check forward when a pay date falls on a bank holiday or a weekend. That changes the day money arrives. It does not change how many pay dates the year contains, which is what this page counts.
How this is worked out
Pay dates are generated by stepping a fixed interval from the date you enter, in UTC throughout. Semimonthly and monthly schedules are built from the calendar instead, on the 15th and the last day of each month, which is why their counts never move. No count on this page is looked up. Each one is produced by walking the year.
The take-home figures come from this site's own paycheck engine, which applies the 2026 federal brackets and standard deduction, then Social Security and Medicare, then the state rate. The payroll tax rates and the Social Security wage base behind that engine are the ones published in IRS Tax Topic 751. The federal brackets and the standard deduction behind the same engine come from this site's vetted 2026 tax tables, last reviewed in August 2026. Everything else on this page, the pay dates, the counts and the extra-check years, is calendar arithmetic derived from the first pay date you enter, and it rests on no outside source at all.
