How the Time and a Half Calculator works
"Time and a half" means an overtime hourly rate equal to 1.5 times your regular hourly rate. This calculator applies the standard overtime pay formula used on most US paychecks: multiply your hourly rate by 1.5 (or by 2 for double time) to get the overtime rate, multiply that by your overtime hours, and add the result to your regular pay.
The formula
For an hourly rate R, regular hours Hreg, overtime hours Hot, and overtime multiplier m (1.5 for time and a half, 2 for double time):
Overtime rate = R × m
Regular pay = R × Hreg
Overtime pay = (R × m) × Hot
Total gross pay = Regular pay + Overtime pay
Worked example
At a $20/hr rate with 40 regular hours and 5 overtime hours at time and a half: the overtime rate is $20 x 1.5 = $30/hr. Regular pay is $20 x 40 = $800. Overtime pay is $30 x 5 = $150. Total gross pay is $800 + $150 = $950 for the week, before taxes and other deductions.
When time and a half applies
In the United States, the Fair Labor Standards Act (FLSA) generally requires covered non-exempt employees to receive at least time and a half for hours worked beyond 40 in a single workweek. Some states set additional rules, such as daily overtime after 8 hours or double time after 12 hours in a day. Exempt employees (many salaried roles meeting specific duties and salary tests) are typically not entitled to overtime pay under the FLSA. Because rules vary by state, industry, and employment classification, confirm your specific eligibility and rate with your employer, HR department, or a labor law professional — this calculator only performs the gross-pay arithmetic.
Time and a half versus double time
Time and a half pays 1.5 times the regular rate; double time pays 2 times the regular rate. Double time is less common and typically applies to specific circumstances defined by state law, union contracts, or employer policy — such as certain holidays or hours beyond a daily threshold. Select the appropriate multiplier above to model either scenario.
What this calculator does not include
- Federal, state, or local tax withholding — the results are gross pay, not take-home pay.
- Shift differentials, bonuses, commissions, or other pay add-ons.
- State-specific daily overtime or seventh-day premium rules that differ from the federal weekly threshold.
- Exempt-employee status determinations — always verify eligibility with a qualified source.
