Overtime Pay Formulas

Overtime Pay (Time and a Half)

OT Pay=Hourly Rate×1.5×OT Hours\text{OT Pay} = \text{Hourly Rate} \times 1.5 \times \text{OT Hours}
Hourly Rate
Your regular straight-time hourly wage
OT Hours
Hours worked beyond 40 in a workweek (FLSA)

Worked example

Calculate overtime pay for $20/hr with 10 overtime hours

Given
Hourly Rate = $20.00
OT Hours = 10
Calculation
OT Pay=20×1.5×10\text{OT Pay} = 20 \times 1.5 \times 10
Result
OT Pay = $300.00

Effective Hourly Rate

Effective Rate=Total Weekly PayTotal Weekly Hours\text{Effective Rate} = \frac{\text{Total Weekly Pay}}{\text{Total Weekly Hours}}
Total Weekly Pay
Regular pay + overtime pay + double-time pay
Total Weekly Hours
All hours worked in the week

Worked example

Effective rate for $800 regular + $300 OT over 50 hours

Given
Total Weekly Pay = $1,100
Total Weekly Hours = 50
Calculation
Effective Rate=110050\text{Effective Rate} = \frac{1100}{50}
Result
Effective Rate = $22.00/hr

Frequently asked questions

How much is time and a half?

Time and a half is 1.5 times your regular hourly rate. If you earn $20/hour, your overtime rate is $30/hour. For every overtime hour, you earn your normal hourly wage plus half of it again.

When does overtime pay start?

Under the federal FLSA, overtime starts after 40 hours in a single workweek for non-exempt employees. Some states go further — California requires overtime after 8 hours in a day and double time after 12 hours in a day or beyond 8 hours on the seventh consecutive workday.

Who is exempt from overtime?

Salaried employees in executive, administrative, professional, and some computer and outside-sales roles can be exempt if they meet both a duties test and a minimum salary threshold. Job title alone does not determine exemption — the actual duties and pay structure do.

Is overtime taxed at a higher rate?

No — this is a common myth. Overtime is taxed as ordinary income. More may be withheld from a large paycheck because withholding tables annualize each check, but your actual tax rate depends on total annual income, and any over-withholding comes back at refund time.

What is double time and when do I get it?

Double time is 2× your regular rate. Federal law does not require it, but some states, union contracts, and employer policies pay double time for holidays, seventh consecutive workdays, or hours beyond 12 in a day (California).

Key terms

FLSA
Fair Labor Standards Act — the US federal law that sets the 40-hour workweek and the 1.5× overtime minimum for non-exempt employees.
Non-Exempt Employee
An employee entitled to overtime pay. Most hourly workers are non-exempt.
Effective Hourly Rate
Total pay divided by total hours worked — what you actually earn per hour once overtime premiums are included.
Regular Rate of Pay
The base rate used for the overtime multiplier. It can include non-discretionary bonuses and shift differentials, not just base wage.
