Time-and-a-Half Rate Calculator
Standard Formula
Overtime Rate = Regular Hourly Rate × 1.5
Under FLSA standards, time and a half pays an extra 50% on top of your standard base rate.
How Time-and-a-Half Rate Calculator Works?
The Time-and-a-Half Rate Calculator works by multiplying your regular hourly rate by 1.5 and showing the result as a new hourly figure. The tool returns 4 values: the 1.5× rate, your straight rate, the 0.5× premium per hour, and the pay for one 8-hour overtime shift.
1Enter the regular hourly rate
Type the base wage printed on your offer letter or paystub, for example $25.00 per hour. The field accepts quarter-dollar steps ($0.25).
2Read the 1.5× overtime rate
The calculator multiplies the base wage by 1.5 and shows the time-and-a-half rate per hour. A $25.00 wage becomes $37.50 per hour.
3Check the premium portion
The 0.5× line shows the extra money added on top of straight pay for each overtime hour. At $25.00 per hour, the premium is $12.50 per hour.
4Compare one overtime shift
The last line multiplies the 1.5× rate by 8 hours (480 minutes), so you see the gross value of one full overtime shift before taxes.
Time-and-a-Half Rate Calculator Formula
The Time-and-a-Half Rate Calculator formula is Overtime Rate = Regular Hourly Rate × 1.5. The formula splits into a straight-time part (1.0×) and a premium part (0.5×).
Time-and-a-half rate
Overtime Rate = Regular Rate × 1.5
Premium per overtime hour
Premium = Regular Rate × 0.5
Pay for one 8-hour overtime shift
Shift Pay = Overtime Rate × 8
- Regular Rate
- The non-overtime hourly wage, in dollars per hour ($/hr).
- 1.5
- The federal overtime multiplier set by the Fair Labor Standards Act (FLSA).
- 0.5
- The half-time premium paid on top of straight-time pay.
- Overtime Rate
- The hourly wage paid for each hour worked past 40 hours in a workweek.
Worked example: $22.40 per hour
Overtime Rate = $22.40 × 1.5 = $33.60 per hour.
Premium = $22.40 × 0.5 = $11.20 extra per overtime hour.
One 8-hour overtime shift pays $33.60 × 8 = $268.80 gross.

$7.25 per hour is the federal minimum wage. Workers in a state with a higher minimum wage use the state figure as the floor.
What is Time-and-a-Half Rate Calculator?
A Time-and-a-Half Rate Calculator is a payroll tool that converts a regular hourly wage into the overtime wage paid at 150% of that wage. The tool answers one question: how much is one overtime hour worth?
The 1.5× multiplier comes from Section 7 of the Fair Labor Standards Act (FLSA). Non-exempt employees in the United States (US) earn at least 1.5 times the regular rate for every hour worked over 40 hours in a fixed 7-day workweek (168 hours). Many employers in Canada, the United Kingdom (UK) and Australia use the same 1.5× figure through contracts or provincial and state rules.
The calculator returns an hourly rate, not a weekly total. Use the result to read a paystub line, quote an overtime rate in a job offer, or set the rate inside payroll software.
What are the uses of Time-and-a-Half Rate Calculator?
There are 5 main uses of the Time-and-a-Half Rate Calculator, ranging from paystub checks to rate setup in payroll software.
Paystub verification
Hourly workers compare the overtime rate printed on a paystub with the exact 1.5× figure for their base wage.
Job offer comparison
Job seekers convert two base wages into overtime rates to see which offer pays more per extra hour.
Payroll setup
Payroll administrators enter the correct overtime rate code for each new hire in systems such as ADP, Gusto or QuickBooks.
Shift pickup decisions
Employees check the value of one 8-hour overtime shift before agreeing to work a Saturday or a holiday week.
Wage negotiation
Workers show managers how a $1.00 raise lifts the overtime rate by $1.50 per hour.
