How to Use This Time and a Half Calculator
The time and a half calculator on this page computes regular pay, overtime pay at 1.5×, and double time pay from your hourly rate and hours worked. Enter your hourly rate, regular hours, and overtime hours, then select whether overtime is paid at 1.5× or 2×. The result shows total pay and your blended effective hourly rate. For tracking daily hours before calculating pay, use our time card calculator.
How to Calculate Time and a Half Pay
Time and a half pay is calculated using a simple formula:
Time and a Half Formula
- Overtime Rate = Hourly Rate × 1.5
- Regular Pay = Regular Hours × Hourly Rate
- Overtime Pay = Overtime Hours × Overtime Rate
- Total Pay = Regular Pay + Overtime Pay
Example: $18/hr, 40 regular hours, 5 overtime hours
- Overtime rate: $18 × 1.5 = $27.00/hr
- Regular pay: 40 × $18 = $720.00
- Overtime pay: 5 × $27 = $135.00
- Total pay: $720 + $135 = $855.00
Time and a Half Pay Chart by Hourly Rate
Common overtime rates at 1.5× for reference:
- $15/hr → Overtime rate: $22.50/hr
- $18/hr → Overtime rate: $27.00/hr
- $20/hr → Overtime rate: $30.00/hr
- $25/hr → Overtime rate: $37.50/hr
- $30/hr → Overtime rate: $45.00/hr
- $35/hr → Overtime rate: $52.50/hr
- $40/hr → Overtime rate: $60.00/hr
- $50/hr → Overtime rate: $75.00/hr
For double time rates, simply double your regular hourly rate.
Federal Overtime Law (FLSA)
The Fair Labor Standards Act (FLSA) requires employers to pay non-exempt employees at least 1.5× their regular rate of pay for all hours worked over 40 in a workweek. The law does not require overtime pay for hours over 8 in a day — that is a state-level rule in some states like California.
Who Is Exempt from Overtime?
Employees classified as exempt under FLSA are not entitled to overtime pay. Exemptions generally apply to executive, administrative, and professional employees who earn above the salary threshold (currently $684/week as of 2020) and meet specific duties tests. Most hourly workers are non-exempt and entitled to overtime.
California Overtime Rules
California has additional overtime rules beyond federal law. In California, employees earn:
- 1.5× pay for hours over 8 in a workday (daily overtime)
- 1.5× pay for the first 8 hours on the 7th consecutive workday
- 2× pay (double time) for hours over 12 in a workday
- 2× pay (double time) for hours over 8 on the 7th consecutive workday
Effective Hourly Rate vs. Overtime Rate
The overtime rate is what you are paid per overtime hour (e.g., $30/hr at 1.5×). The effective hourly rate is your total pay divided by total hours — this blended rate is lower than the overtime rate because most of your hours are paid at the regular rate. For example, $855 total pay ÷ 45 total hours = $19.00/hr effective rate, even though overtime was paid at $27/hr. For workforce planning and staffing decisions, our full-time equivalent calculator converts part-time and overtime hours into FTE headcount figures used in HR and budgeting.
