$18 an Hour Overtime Calculator

If you earn $18.00 an hour, your overtime rate depends on how your employer pays for hours over 40 in a workweek.

The Fair Labor Standards Act (FLSA) generally requires most hourly workers to receive 1.5 times their regular rate for overtime. Some employers also offer double time or 2.5x on holidays or weekends.

How Overtime Pay Works at $18.00 an Hour

Below are common overtime multipliers and what they pay per hour at an $18.00 base rate.

Overtime RateMultiplierHourly PayExample: 5 Overtime HoursTotal Overtime Pay
Standard Overtime (Time-and-a-Half)1.5x$27.00/hour5 × $27.00 = $135.00$135.00
Double Time2x$36.00/hour5 × $36.00 = $180.00$180.00
Weekend/Holiday Overtime (2.5x)2.5x$45.00/hour5 × $45.00 = $225.00$225.00

Here is a straightforward weekly example to show the impact:

If you work 45 hours in one week, your gross pay would be:

  • Regular Pay: 40 hours × $18.00 = $720
  • Overtime Pay: 5 hours × $27.00 = $135
  • Total Weekly Pay = $855 before taxes

Overtime Pay Formula

Overtime Pay = Hourly Rate × Overtime Multiplier × Overtime Hours

Example:

If you earn $18.00/hour and work 6 overtime hours at 1.5x pay, then:

→ $18.00 × 1.5 × 6 = $162 in overtime pay

If those same 6 hours were paid at double time, you would get $216 instead.

Know Your Overtime Rights

The FLSA protects most non exempt hourly workers, requiring at least 1.5x pay for hours over 40 in a workweek. Keep these points in mind:

  • Eligible employees must receive overtime at the legally required rate.
  • Exempt employees such as some salaried managers may not qualify for overtime.
  • State laws can offer stronger rules, like daily overtime in California after 8 hours.

If you are unsure about your status, review your pay stub or speak with HR. For disputes you can contact the Department of Labor or your state labor agency.

Why $18.00/Hour Workers Benefit From Overtime

At $18.00 per hour, overtime is an efficient way to boost income without changing jobs. Here are three reasons it helps:

  1. Extra hours compound quickly. Small amounts of overtime can translate into meaningful monthly and annual income gains.
  2. Common in many industries. Employers in healthcare, Hospitality, Logistics, and Manufacturing often rely on overtime staffing.
  3. Higher multipliers on nights, weekends, and holidays can substantially increase short term earnings.

Example: working 8 overtime hours each week for a month equals 32 overtime hours. At 1.5x that adds $864 in one month.
