Semi-Monthly Pay Calculator
Calculate semi-monthly pay (24 pay periods/yr), net paycheck after taxes and deductions, annual salary conversion, and bi-weekly pay schedule comparison.
What is a Semi-Monthly Pay Calculator?
A Semi-Monthly Pay Calculator estimates your gross and net paycheck amount when you are paid twice per month (exactly 24 pay periods per year). It converts annual salary or hourly wages into gross semi-monthly earnings and deducts federal, state, and FICA taxes along with pre-tax and post-tax deductions.
Semi-Monthly vs. Bi-Weekly Pay Schedules
Many employees confuse semi-monthly pay with bi-weekly pay. Here is how they differ:
- Semi-Monthly (24 Paychecks/Year): Payments occur on specific calendar dates (such as the 1st and 15th, or 15th and last day of the month). Each paycheck covers 1/24th of your annual salary.
- Bi-Weekly (26 Paychecks/Year): Payments occur every two weeks on a set day of the week (such as every second Friday). Because there are 52 weeks in a year, bi-weekly employees receive 26 paychecks annually—including two months with three paychecks.
Semi-Monthly Pay Formula
$$\text{Gross Semi-Monthly Pay} = \frac{\text{Annual Salary}}{24}$$ $$\text{Hourly Semi-Monthly Gross} = \text{Hourly Rate} \times \left( \frac{\text{Hours per Week} \times 52}{24} \right)$$Frequently Asked Questions
How many paychecks do you get in a semi-monthly schedule?
You receive exactly 24 paychecks per year, with 2 paychecks per calendar month.
Is semi-monthly pay higher than bi-weekly pay per check?
Yes. For the same annual salary, a semi-monthly paycheck is larger than a bi-weekly paycheck because the salary is divided by 24 instead of 26.
How do hourly workers calculate semi-monthly pay?
Hourly workers calculate total annual hours (e.g. 40 hours/week × 52 weeks = 2,080 hours), multiply by their hourly wage, and divide by 24 pay periods.
