Biweekly pay usually means one paycheck every two weeks, or 26 paychecks in a 52-week year. Semimonthly means two paychecks each month, or 24 per year. The annual salary can be identical while each paycheck differs.
$52,000 salary example
- Biweekly:
$52,000 ÷ 26 = $2,000gross per paycheck. - Semimonthly:
$52,000 ÷ 24 = $2,166.67gross per paycheck.
The semimonthly check is larger because there are two fewer checks during the year. Total annual gross pay remains $52,000.
Calendar rhythm
Biweekly employees are often paid on the same weekday, such as every other Friday. Most years have two months with three biweekly paychecks. Semimonthly employees are often paid on fixed dates such as the 15th and last day of each month, so every month has two pay periods.
Pay dates can move for weekends or holidays, and employer practices vary. Check the actual payroll calendar rather than assuming a particular date rule.
How a raise appears
A $2,500 annual raise adds about $96.15 to each of 26 biweekly paychecks. The same annual raise adds about $104.17 to each of 24 semimonthly paychecks. Both equal $2,500 across the year before taxes.
Budgeting implications
With biweekly pay, a monthly budget based on exactly two checks leaves the two three-check months as irregular cash-flow events. With semimonthly pay, the two-check rhythm is consistent, but pay dates may not fall on the same weekday.
Use the main calculator to compare before, after, and increase amounts for both periods side by side. Do not enter a biweekly amount as semimonthly or vice versa.
