Overtime Calculator

Calculate overtime pay under FLSA: time-and-a-half (1.5×) beyond 40h, double time (2×), weighted multi-rate jobs and nondiscretionary bonuses in the regular rate.

Direct Answer

Under the US Fair Labor Standards Act (FLSA), non-exempt employees earn 1.5 times their regular hourly rate for all hours worked exceeding 40 in a single workweek. An employee earning $20/hr receives $30/hr for each overtime hour worked.

FLSA mandates 1.5× pay for non-exempt hours worked over 40 in a workweek.

Weighted multi-rate (multiple jobs)

If you worked at different rates this week, add them. Regular rate becomes the weighted average including bonus.

How to use

1Enter hourly rate and total hours worked in the week. Adjust regular threshold if not 40h.
2Set overtime multiplier (1.5× standard), double-time hours if any, and any weekly bonus included in regular rate.
3For multiple rates, open weighted multi-rate, add each rate/hours — we use the weighted average as regular rate.

Overtime Formulas & FLSA Rules

Regular Pay = Regular Hours × Base Hourly Rate
Overtime Rate (1.5x) = Base Hourly Rate × 1.5
Overtime Pay = Overtime Hours × (Base Hourly Rate × 1.5)
Double Time Pay (2.0x) = Double Time Hours × (Base Hourly Rate × 2.0)
Total Gross Pay = Regular Pay + Overtime Pay + Double Time Pay

Variable	Name	Meaning & Example
R_reg	Regular Rate	Standard hourly base pay rate ($20.00)
R_ot	Overtime Rate	Time-and-a-half rate (Regular Rate × 1.5) ($30.00)
H_ot	Overtime Hours	Weekly hours worked beyond 40.0 (10 hrs)

Fair Labor Standards Act (FLSA) Guidelines:

Under US federal law, non-exempt hourly workers must receive overtime pay for all hours worked exceeding 40 hours in a 7-day workweek.
The federal minimum overtime rate is 1.5 times the regular hourly rate ('time and a half').
Double time (2.0×) is mandated in certain jurisdictions (such as California for shifts over 12 hours in a single day or over 8 hours on the 7th consecutive day) or under union agreements and holiday policies.

Examples

Standard 48-Hour Workweek at $25.00/Hour

Step 1: Regular Hours (capped at 40) × $25.00 = 40 × $25.00 = $1,000.00.
Step 2: Overtime Hours = 48 − 40 = 8 hours.
Step 3: Overtime Rate = $25.00 × 1.5 = $37.50/hr.
Step 4: Overtime Pay = 8 × $37.50 = $300.00.
Step 5: Total Gross Pay = $1,000.00 + $300.00 = $1,300.00.

Total Gross Pay: $1,300.00 (Overtime: $300.00)

California Double-Time Example (40 Regular, 8 Overtime 1.5x, 4 Double Time 2.0x) at $30/hr

Regular Pay: 40 hrs × $30.00 = $1,200.00.
Overtime Pay (1.5x): 8 hrs × $45.00 = $360.00.
Double Time Pay (2.0x): 4 hrs × $60.00 = $240.00.
Total Gross Pay: $1,200 + $360 + $240 = $1,800.00.

Total Gross Pay: $1,800.00

About

The Overtime Calculator estimates gross overtime pay under the FLSA model. Enter your hourly rate, total hours worked in the week, and any weekly bonus, and the tool computes regular pay, overtime at time-and-a-half beyond the 40-hour threshold, and double-time hours where applicable. It supports weighted multi-rate averaging for weeks worked at different pay rates, and it includes nondiscretionary bonuses in the regular rate. Payroll staff, managers, and hourly employees use it to verify weekly wages and plan shift coverage, keeping in mind that state rules may exceed federal requirements.

Frequently asked questions

When does overtime pay apply under federal law?

Under the US Fair Labor Standards Act (FLSA), overtime applies when a non-exempt employee works more than 40 hours in a single standard 7-day workweek. Overtime is generally not required for daily hours over 8, except in specific states like California, Alaska, and Nevada.

How is time and a half calculated?

Time and a half is calculated by multiplying the standard hourly rate by 1.5. For example, if you earn $20.00 per hour, your overtime rate is $20.00 × 1.5 = $30.00 per hour.

Does overtime pay apply to salary employees?

Salaried employees may be eligible for overtime unless they meet federal exemption criteria (executive, administrative, professional exemptions) and earn above the statutory salary threshold.

When is an employer legally required to pay overtime?

Under the federal FLSA, employers must pay time-and-a-half to covered non-exempt employees for all hours worked over 40 in a single 7-day workweek. State laws (such as California) may also mandate daily overtime for hours over 8 per day.

How is double time calculated?

Double time pays twice (2.0×) the standard hourly wage. While not mandated by federal FLSA law, double time is frequently required by union contracts, company policies, or state regulations (e.g., California after 12 daily hours or on the 7th consecutive day).

Do bonuses and shift differentials count toward overtime pay?

Yes. The FLSA requires non-discretionary bonuses, shift differentials, and commissions to be factored into your "regular rate of pay" before computing the 1.5× overtime multiplier.
