Ever heard of “semi-monthly pay” and not have a clue about what it is? Perhaps even getting paid in such a format and not having a full understanding? Don’t fret, you’re not alone! Most have a little trouble with semi-monthly pay periods. Let’s go in and clarify the mystery, then!
Key Points
- Employees under the semi-monthly pay schedule receive their paychecks twice a month on the same day, typically the 15th and 30th.
- Employees are paid on the same day every other week under the biweekly pay schedule.
- Biweekly workers earn 26 payments a year, compared to 24 for semi-monthly workers.
- For paid workers, semi-monthly pay intervals are ideal, whereas hourly workers prefer biweekly.
What Are Semi-Monthly Pay Periods?
Semi-monthly pay periods involve a salary schedule under which workers receive two paychecks in a month, usually at definite days. Employers most frequently schedule such days and make them uniform for an entire year. Don’t confuse it with biweekly pay; a pay schedule is received every two weeks, though. There is a subtle but important difference that will become clear later.
To rephrase, semi-monthly pay is a pay schedule in which workers have their pay twice a month, most frequently on designated days, for example, the 15th and at the end of the month. Unlike a biweekly pay schedule, in which workers have pay every two weeks for a grand total of 26 pay periods in a year, semi-monthly pay schedules produce 24 pay periods in a year. Unlike monthly pay, monthly pay generates only 12 pay periods in a year.
According to statistics at the Bureau of Labor Statistics, approximately 19.8% of private U.S. employers use a semimonthly pay schedule, and it is a common practice for salaried jobs. Employers use it for ease in budgeting and financial planning, for offering predictable, routine payments, and for simplifying payroll. There are 24 pay periods in a semi-month, and that is purely because you’re receiving two paychecks a month, and a year has 12 months.
How Are Semi-Monthly Pay Periods Calculated?
This is where it gets a little tricky. Semi-monthly pay periods are usually based on specific dates, not a number of days. Common pay dates are the 1st and 15th of each month or the 15th and last day of each month.
Your employer will calculate your gross salary for your semi-monthly paycheck by taking your annual salary and dividing it in 24 parts. Don’t forget, taxes and withholdings will be taken out, and your actual pay will therefore not be your gross pay.

To find semi-monthly pay, you must convert an annual salary into the amount earned per each of the two pay periods per month. Here’s how:
Semi-monthly salary = Gross annual salary / 24
Gross annual salary: This is your total gross salary over a year.
24: Represents a 12-month period when your payment is twice a monthly payment. Since a month holds two pay periods and a year holds 12 months, multiply 12 and two together to obtain 24.
Calculation example:
$60,000 gross salary per annum ÷ 24 = $2,500
In this scenario, $2,500 would be the salary for a semi-month, excluding taxes and any withholdings.
How Do Semi-Monthly Pay Periods Work? A Simple Breakdown
Let’s break it down with an example. Let’s say that your salary comes in on the 1st and 15th of a month. On 1st, your first paycheck for a given month will come in, and it will pay your salary for the 16th of a preceding month through a preceding month’s end date. On 15th, your second paycheck will come in, and it will pay your salary for 1st through 15th of a current month.
Here is an overview of how such a payment schedule operates:
- Pay periods: There are two pay periods in a month (e.g., particular dates like the first and 15th of a month).
- Monthly pay: A monthly salary is split into two paycheques. For a monthly salary of $4,000, for example, a pay of $2,000 will be received in each paycheck.
- Yearly paychecks: Employees will have 24 paychecks in a year.
Semi-Monthly Pay Periods for 2025: A Closer Look
This section of the document provides a specific example of how a semi-monthly pay schedule would play out in the calendar year 2025. It assumes a very common scenario where employees are paid on the 1st and the 15th of each month. Following is a breakdown of how semi-monthly pay periods would fall in 2025, with pay dates on the 1st and 15th of each month:
Here’s a table with some added explanation:
| Pay Period | Pay Date | Explanation |
| 1 | January 1, 2025 | First paycheck of the year, covering the second half of December 2024. |
| 2 | January 15, 2025 | Second paycheck of January, covering the first half of January 2025. |
| 3 | February 1, 2025 | First paycheck of February, covering the second half of January 2025. |
| … | … | This pattern continues throughout the year. |
| 22 | December 1, 2025 | First paycheck of December, covering the second half of November 2025. |
| 23 | December 15, 2025 | Second paycheck of December, covering the first half of December 2025. |
| 24 | January 1, 2026* | The final paycheck of the 2025 payroll year might be paid on January 1, 2026, depending on company policy. This is because of the way semi-monthly pay periods are calculated to pay for work already completed in the past.. |
Key Points and Implications:
- Consistency: The table highlights the consistent and predictable nature of semi-monthly pay. Employees can rely on receiving their pay on those specific dates, which helps with financial planning.
- Overlapping Pay Periods: It’s important to realize that each paycheck covers a period of work that includes days in the previous or subsequent month. The January 1st paycheck, for example, covers work done in December of the previous year. This is a hallmark of semi-monthly and other time-based pay periods.
- Year-End Pay: The asterisk (*) next to the final pay date is crucial. Because the last semi-monthly pay period of the year spans the last 15 days of December, that pay is frequently paid on the first business day of January. This is very company and accounting practice-specific; it varies, so be aware of your specific situation. It’s a good reminder that paychecks don’t always align perfectly with calendar months.
- Practical Application: This table can be very useful for employees to:
- Plan their budget around known pay dates.
- Understand when they are getting paid for specific periods of work.
- Verify their paychecks and ensure they are being paid correctly.
In essence, the “Semi-Monthly Pay Periods for 2025” section is a practical demonstration of how semi-monthly pay works in the real world. It shows the process of the pay schedule and helps to clear up any confusion about how pay periods and calendar months relate to each other.
Keep in mind that your 2025 final paycheck may actually be received in 2026, depending on your company's policies.
Semi-Monthly vs. Bi-Weekly: Know the Difference
Now, for the big one: What is the difference between semi-monthly and biweekly pay?
- Semi-Monthly: Paid twice a month on specific dates.
- Bi-weekly: Paid every two weeks.
The main difference is that semi-monthly pay is scheduled, but biweekly pay varies a little over a period of a year. A year consists of 52 weeks; 26 pay periods for a biweekly schedule occur in a year. Because a few months have five weeks, in such months, three paychecks will occur in them under a biweekly schedule.

Semi-Monthly vs. Bi-Weekly: Know the Difference
| Feature | Semi-Monthly Pay | Bi-Weekly Pay |
| Pay Frequency | Twice a month on specific dates. | Every two weeks. |
| Pay Periods per Year | 24 | 26 |
| Pay Schedule | Fixed and predictable. | Varies slightly throughout the year. |
| Monthly Paychecks | Two | May have two or three. |
Advantages and Disadvantages of Semi-Monthly Pay
Like any payroll system, semi-monthly pay both has its advantages and its disadvantages.
Semi-monthly payment means getting paid twice a month. It is different from biweekly (every two weeks) or monthly (once a month) payments. Here is the key information:
- Frequency: Twice a month
- Pay Periods: 24 pay periods per annum (12 months x 2).
- Schedule: Typically, employers set specific pay dates, such as the 1st and 15th of each month. This makes budgeting easier.
- Calculation: Your salary is divided into 24 monthly installments.
Example:
If your annual salary is $60,000, your semi-monthly pay will be $2,500 ($60,000 ÷ 24 = $2,500).
Key Differences:
- Semi-monthly: Fixed date, 24 payments/year
- Bi-weekly: Every two weeks, 26 payments/year.
Why it Matters:
- Knowing your pay schedule is important for managing your money. Semi-monthly pay offers predictability, which can help with budgeting.
Advantages:
- Predictability: You have a specific pay date.
- Budgeting: Easier to budget your expenses with a predictable pay schedule.
Disadvantages:
- Fewer Paychecks: Two fewer paychecks a year compared to biweekly pay.
- Timing: If your pay days fall over weekends or holidays, then your payments will be delayed.
Key Takeaway: A Final Word
Remember, understanding your pay schedule is key to successful financial planning. Regardless of your pay being semi-monthly or biweekly, track your paychecks and budget according to them. And in case of any query about your pay, don’t forget to contact your HR department or your employer. As the saying goes, “Time is money.” Thus, manage your pay and your time wisely and become cognizant of your pay schedule!
