Quick Answer: Semi-monthly pay frequency means twice per month, resulting in exactly 24 paychecks per year. This differs from bi-weekly pay (26 paychecks per year) and creates tracking challenges when managing hourly teams, since federal overtime rules require 7-day workweek calculations.
How Does Semi-monthly Differ from Bi-weekly Pay Schedules?
The differences in these payment frequencies affect your cash flow, compliance requirements, and employee satisfaction. Semi-monthly periods (13-16 days) routinely split workweeks across two paychecks. Federal overtime rules require tracking by 7-day workweeks, creating a compliance mismatch that increases error risk.
Semi-monthly delivers 24 paychecks annually on fixed calendar dates (like the 15th and last day of each month), while bi-weekly provides 26 paychecks every 14 days on the same weekday. This creates two "extra paycheck" months yearly with bi-weekly, which don't exist with semi-monthly.
For your hourly teams earning $48,000 annually, semi-monthly means $2,000 paychecks versus $1,846.15 bi-weekly paychecks. However, the Fair Labor Standards Act requires overtime calculated by workweeks, not pay periods. Semi-monthly periods routinely split workweeks across two paychecks, creating complex overtime calculations that increase your risk of violations.
Fixed calendar dates mean occasional weekend or holiday adjustments. When the 15th falls on Saturday, you'll typically process payroll on Friday.
What Challenges Does Semi-monthly Pay Create for Hourly Businesses?
Unlike salaried employees who receive consistent amounts, your hourly team faces paycheck variability with semi-monthly pay, even when schedules remain stable. Pay periods vary from 13-16 days depending on the month, creating full-time paychecks that range from 86-93 hours, compared to the consistent 80-hour bi-weekly pay periods.
Semi-monthly pay periods vary from 13 to 16 days per month, making paycheck amounts unpredictable for hourly workers. A full-time server working 40 hours weekly might see 86 hours in one pay period and 93 hours in the next, purely due to calendar differences, not schedule changes. According to the Brookings Institution’s research, restaurant and retail workers already experience 32% week-to-week hour variation. Semi-monthly pay periods that don't align with when hours are actually worked create additional budgeting challenges.
State requirements add another layer:
- California requires wages earned from the 1st-15th to be paid by the 26th, while wages from the 16th through the month-end must be paid by the 10th of the following month.
- New York mandates weekly payment for manual workers.
The biggest risk involves overtime tracking: Federal overtime rules require overtime to be calculated on a 7-day workweek, but semi-monthly periods routinely split workweeks across two separate paychecks. According to the Field Operations Handbook, you must track hours by workweek while paying semi-monthly, then accurately allocate overtime premiums to the correct paycheck.
Your server might work 30 hours in week one and 45 hours in week two. Overtime hours in week two must be calculated at time-and-a-half, but determining which paycheck gets the premium requires tracking hours separately by workweek. Without automated systems, errors in overtime calculations create DOL liability risks.
How Does Homebase Help with Semi-Monthly Payroll Management?
Managing semi-monthly payroll for hourly teams requires careful attention to federal overtime rules, particularly when workweeks split across pay periods. Your time tracking system must capture precise hours worked by workweek, while the payroll system must correctly apply federal and state overtime rules across split workweeks. Homebase's payroll software, time clock, and timesheets help capture and organize this data for successful semi-monthly payroll management.
Understanding semi-monthly frequency helps you make informed payroll decisions that balance administrative efficiency with employee needs and compliance requirements.
