What Does OT Premium Mean on a Paystub?
An OT premium row often means payroll is adding only the extra half-time amount because straight time was already paid for all hours.

OT premium on a paystub usually means the extra overtime premium paid above straight-time wages. In many payroll systems, the row is not the whole overtime paycheck line. It may only be the additional half-time amount that makes overtime equal time and a half.
Quick answer
If you already received straight-time pay for all hours worked, an "OT premium" row may show only the extra 0.5x premium for hours over 40. If your paystub does not show straight-time pay for those overtime hours anywhere else, then the overtime row should usually reflect the full 1.5x overtime rate.
Check the OT premium math
Use the regular-rate calculator when the week includes bonuses, commissions, shift differentials, or multiple rates. Use the time-and-a-half calculator for a simple hourly week.
Why payroll separates OT premium from regular pay
Federal overtime is based on paying covered non-exempt employees at least one and one-half times their regular rate for hours worked over 40 in a workweek. Payroll systems can show that result in two different ways.
Full-rate method
The paystub shows 40 regular hours and a separate overtime row paid at 1.5x. At $20/hour, 5 overtime hours appear as 5 x $30 = $150.
Premium-only method
The paystub shows 45 straight-time hours plus an OT premium row for the extra 0.5x. At $20/hour, 5 premium hours appear as 5 x $10 = $50.
Example: OT premium is correct
45-hour week at $20/hour
When OT premium may be wrong
- The paystub only pays 40 regular hours and then pays overtime hours at 0.5x.
- The OT premium is calculated from the base hourly rate when bonuses should be included.
- Shift differentials or multiple job rates are missing from the regular-rate base.
- The overtime hours do not match actual hours worked over 40 or state daily overtime.
- The paystub uses paid leave hours as overtime hours even though the policy says otherwise.
If the week includes extra compensation, review the regular rate of pay guide before deciding whether the premium row is correct.
FAQ
Is OT premium the same as overtime pay?
Sometimes. It can mean the whole overtime payment, but many paystubs use it for the extra half-time premium only.
Why does my OT premium rate look lower?
A lower premium rate often means payroll already paid straight time somewhere else on the paystub. Check total gross pay, not just the label.
