What Is an Overtime Calculator?
How overtime pay rules shape a paycheck.
Overtime pay explained
An Overtime Calculator works out the extra pay owed for hours beyond a standard week. In the US, the Fair Labor Standards Act (FLSA) requires non-exempt employees to receive at least 1.5× their regular rate for every hour over 40 in a workweek.
The formula is OT Pay = OT Hours × (Hourly Rate × OT Multiplier). Work 48 hours at $20 an hour and the 8 overtime hours are paid at $30, adding $240 to the $800 of regular pay.
Daily vs weekly overtime
Federal law only looks at the weekly 40-hour line, but some states go further. California, for example, pays 1.5× for time over 8 hours in a single day and double time (2×) for time over 12 hours.
Who qualifies for overtime?
Non-exempt employees under the FLSA are entitled to overtime. Exempt staff — usually salaried employees in executive, administrative or professional roles — are not covered by the federal overtime rule.
When to Use an Overtime Calculator
Situations where quick overtime calculations pay off.
Paycheck Verification
Check that the overtime pay on your payslip is right by confirming the regular hours and OT hours each period.
Payroll Processing
Payroll and HR teams can confirm employee earnings across different pay rates and thresholds before running payroll.
Budget Planning
Estimate weekly or monthly earnings with overtime included, and see what extra shifts would add.
Labor Law Compliance
Apply the right overtime multiplier and threshold for FLSA overtime rules, state law or a union agreement.
Manufacturing & Shifts
Shift workers regularly pass 40 hours/week; price rotating shifts, weekend work and holiday double-time correctly.
Freelance & Contract Work
Use overtime logic to set premium rates for rush work that goes beyond your normal contracted hours.
Quick Overtime Calculation Examples
Four common overtime scenarios, worked through.
Standard 48-hour workweek
48 hours at $20/hr with 1.5× after 40: $800 regular + $240 overtime = $1,040 total.
Heavy overtime week
55 hours at $25/hr with 1.5×: 40 regular hours ($1,000) + 15 overtime hours at $37.50 ($562.50) = $1,562.50 total.
Double-time weekend
50 hours at $18/hr with 2× overtime: 40 regular hours ($720) + 10 overtime hours at $36 ($360) = $1,080 total.
Part-time with overtime
Some contracts start overtime earlier. 35 hours at $22/hr with overtime after 30: 30 regular hours ($660) + 5 overtime hours at $33 ($165) = $825 total.
Overtime Calculator FAQ
Answers to common questions about the Overtime Calculator.
Take the overtime threshold — usually 40 hours a week — away from the total hours worked. Every hour above it is paid at the overtime rate, most often 1.5 times the regular hourly rate; the hours up to the threshold are paid normally.
In the United States, the Fair Labor Standards Act (FLSA) sets overtime at more than 40 hours in a workweek, paid at 1.5 times the regular rate for non-exempt employees. Some states add daily rules — California, for example, starts overtime after 8 hours in a day.
It means each overtime hour pays one and a half times your normal rate. At $20 an hour, the overtime rate is $30 an hour (20 × 1.5).
Yes. Double time (2×) applies under some state laws and contracts — in California, for instance, hours beyond 12 in one workday are paid at double time, and many union agreements use 2× for holidays or weekends.
Add up the week's hours and subtract the threshold (for example 40). Pay the regular hours at your normal rate and the overtime hours at rate × multiplier, then add the two amounts together.

Under the federal FLSA, overtime is based on hours actually worked, so paid holidays, vacation and sick time usually do not count toward the 40-hour threshold. Some employers and union contracts count them anyway, so check your own policy.
