An overtime pay calculator converts your regular hourly wage into an overtime rate using a multiplier, then applies that rate to your overtime hours. The most common multiplier is 1.5x (time and a half), which is the federal minimum under the Fair Labor Standards Act. The calculator above also supports double time (2x) and any custom multiplier your employer or state law requires.
The math is simple. Your overtime hourly rate equals your regular wage multiplied by the overtime multiplier. Overtime pay equals that rate times the number of overtime hours. Regular pay equals your regular wage times your regular hours. Total gross pay is the sum of regular and overtime pay. The calculator handles the pay period scaling (weekly, biweekly, or monthly) and computes annualized gross by multiplying the weekly total by 52.
All figures are gross, meaning before any taxes, deductions, or withholdings. Overtime laws and exempt classifications vary by state, so the results are estimates for informational purposes. Consult your payroll department or the Department of Labor for guidance specific to your situation.
Time and a half means your overtime rate is 1.5 times your regular hourly wage. It is the standard overtime rate required by the federal FLSA for non-exempt employees who work more than 40 hours in a single workweek. To calculate it, multiply your hourly wage by 1.5. For example, $18 per hour times 1.5 equals $27 per hour.
Time and a Half Rates for Common Hourly Wages
$15/hr: $22.50 OT rate. $18/hr: $27.00 OT rate. $20/hr: $30.00 OT rate. $22/hr: $33.00 OT rate. $25/hr: $37.50 OT rate. $28/hr: $42.00 OT rate. $30/hr: $45.00 OT rate.
To use the calculator for time and a half, select "Time and a Half (1.5x)" from the Overtime Multiplier dropdown. The calculator will instantly show your overtime rate, overtime pay, regular pay, and total gross for the selected pay period. The annualized gross estimate shows what you would earn in a full year at the same hours and wage.
Time and a half for $18 an hour is $27.00 per hour. If you work 5 overtime hours at that rate in a single week, your overtime pay is $135.00 (5 hours times $27). Your regular pay for 40 hours at $18 is $720.00. Combined, your weekly gross pay is $855.00.
Over a full year of 52 weeks with consistent overtime, that weekly gross of $855 translates to $44,460 per year in gross income. Without the 5 overtime hours, the same $18 wage produces $37,440 annually (40 hours times $18 times 52). The 5 weekly overtime hours add $7,020 to annual gross earnings.
These figures represent gross income before federal income tax, state income tax, Social Security (6.2%), Medicare (1.45%), and any other deductions like health insurance or retirement contributions. Actual take-home pay will be lower.
Double time means you earn twice your regular hourly rate for qualifying hours. At $18 per hour, double time is $36 per hour. Five overtime hours at double time produces $180 in overtime pay, compared to $135 at time and a half. The calculator above handles double time by selecting "Double Time (2x)" from the multiplier dropdown.
Federal law does not require double time. It is mandated in certain situations by state law or contract. California requires double time for any hours worked beyond 12 in a single day, and for the first 8 hours worked on the 7th consecutive day in a workweek. Some union collective bargaining agreements specify double time for holidays, weekends, or night shifts, but these are contractual benefits, not legal requirements in most states.
The calculator also supports custom multipliers. If your employer or state law requires a rate other than 1.5x or 2x (for example, 2.5x for certain penalty rates), select "Custom Multiplier" and enter the exact value.
Federal law does not require employers to pay extra for work performed on holidays. Holiday premium pay is entirely a matter of employer policy, union contract, or state statute. Many employers offer 1.5x pay for holiday work as a benefit, and some offer double time. The overtime pay calculator above can estimate holiday earnings by selecting the multiplier that matches your employer's policy.
It is important to distinguish holiday pay from overtime pay. Holiday premium pay applies to hours worked on a specific date regardless of how many total hours you have worked that week. Overtime pay under the FLSA is based on exceeding 40 total hours in the workweek. In some cases, both can apply: holiday hours count toward the 40-hour weekly total, so if your holiday shift pushes you over 40 hours, those hours may qualify for both holiday premium and overtime rates depending on your employer's policy.
Some states have additional holiday pay protections. For example, Massachusetts requires premium pay for retail employees who work on certain holidays. Rhode Island has similar provisions. Most states, however, leave holiday pay to employer discretion. Check with your state labor department and your employee handbook for the rules that apply to your situation.
