Semi-monthly pay means you're paid twice per month — 24 pay periods per year, typically on fixed dates such as the 15th and the last day of the month. This calculator converts your hourly rate into that semi-monthly gross paycheck figure.
Formula: Semi-monthly gross pay = (hourly rate x hours per week x weeks per year) / 24

How Semi-Monthly Pay Is Calculated
Worked example: $25/hour x 40 hours/week x 52 weeks/year / 24 = $2,166.67 semi-monthly gross pay.
Semi-monthly pay means twice per month, so 12 months x 2 = 24 pay periods per year — unlike biweekly, which is based on a fixed 2-week interval rather than the calendar month.
Working fewer hours per week lowers the semi-monthly figure proportionally. See the Hourly to Monthly Salary Calculator for a
monthly view of the same pay.
Working fewer than 52 weeks per year lowers the annualized semi-monthly figure, since it's derived directly from your annual gross salary. See the Hourly to Yearly Salary Calculator for the full
annual breakdown.
Semi-monthly gross pay equals your annual gross salary divided by 24: (hourly rate x hours per week x weeks per year) / 24. At $25/hour, 40 hours/week, and 52 weeks/year, that's $52,000 / 24 = $2,166.67 per semi-monthly paycheck.
Why are there 24 semi-monthly pay periods instead of 26?
Semi-monthly means twice per month, and 12 months x 2 = 24 pay periods per year — unlike biweekly, which is based on a fixed 2-week interval (52 weeks / 2 = 26 periods) rather than the calendar month.
Is semi-monthly pay the same as biweekly pay?
No. Semi-monthly means paid twice per month (24 paychecks/year), typically on fixed dates; biweekly means paid every 2 weeks (26 paychecks/year). See the Hourly to Biweekly Salary Calculator if that matches your schedule instead.
Why can semi-monthly pay periods cover different numbers of days or hours?
Because semi-monthly periods run on fixed calendar dates (such as the 1st-15th and 16th-end of month), and months don't all have the same number of days or weekdays — even though the annual total stays the same.
What formula does this calculator use?
Semi-monthly gross pay = (hourly rate x hours per week x weeks per year) / 24
Are these results gross or net values?
Primary conversion outputs are gross unless the mode explicitly includes tax or deduction assumptions for estimated net values.
