US Overtime Calculator: FLSA 1.5x, Double Time and Paycheck

US overtime paycheck: regular rate, time and a half, double time

Under the federal FLSA, every hour over 40 in a workweek must be paid at least 1.5 times the regular rate, an average rate that includes non-discretionary bonuses. The tool computes that rate, gross pay with 1.5x and 2x hours, then net pay after FICA (7.65%) and the tax rates you enter. Example: $28.50 an hour, 52 hours and a $150 bonus give $1,851.69 gross.

The calculation

1. Regular rate = (base rate × all hours + weekly bonus) ÷ total hours.
2. Gross = regular hours × regular rate + overtime hours × regular rate × 1.5 + double-time hours × regular rate × 2.
3. Deductions: Social Security 6.2% and Medicare 1.45% (FICA), then federal and state income tax at the rates you enter, applied to gross pay.

Worked example

$28.50 an hour, 40 regular hours, 10 hours at 1.5x, 2 hours at 2x and a $150 bonus: 52 hours and $1,632 of straight-time pay, so a regular rate of $31.38. Gross pay is $1,851.69 ($1,255.38 + $470.77 + $125.54), $20.19 more than using the base rate alone ($1,831.50). After $141.65 of FICA, $222.20 of federal tax at 12% and $83.33 of state tax at 4.5%, net pay is $1,404.51.

Assumptions and limits

• You split the hours yourself between regular, 1.5x and 2x: the tool applies neither the 40-hour threshold nor daily thresholds.
• The FLSA does not require double time. It comes from state law, such as California (over 12 hours in a day or over 8 hours on the seventh consecutive day), or from a contract.
• Meal breaks are not deducted here; the site's timesheet calculator handles them from clock times.
• Flat tax rates on all gross pay, with no W-4 withholding tables, no Social Security wage base and no Additional Medicare Tax. Exempt employees are not covered.

This is an estimate and does not replace a payroll service.

Frequently Asked Questions

How do I calculate the regular rate when there is a bonus?

Add straight-time pay for all hours and the non-discretionary bonus, then divide by hours worked. With 52 hours at $28.50 and a $150 bonus, that is $1,632 ÷ 52 = $31.38. Overtime is then paid at 1.5 times that rate, not 1.5 times the base rate.

After how many hours is overtime due in the US?

Federal law (FLSA) only counts by the week: every hour over 40 is paid at least 1.5 times the regular rate, with no daily threshold. Some states add a daily threshold: in California, overtime starts after 8 hours in a day.

Is double time required?

Not federally; the FLSA only requires the 50% premium. California requires twice the regular rate after 12 hours in a day and after 8 hours on the seventh consecutive workday of the week. Elsewhere it depends on the contract or a collective agreement.

Why is net pay so much lower than gross?

The tool takes off 7.65% FICA (6.2% Social Security and 1.45% Medicare), then the federal and state rates you enter, all applied to gross pay. In the default example, $1,851.69 gross becomes $1,404.51 net. A real paycheck follows IRS withholding tables, so the amount can differ.
