Overtime Calculator

Understanding Extra Hours Pay

Overtime pay rewards employees who work beyond standard hours with premium compensation—typically 1.5 times their regular rate for hours exceeding 40 per week. The calculator computes overtime earnings, showing how extra hours translate to additional income and helping workers understand the true value of their time.

For many hourly workers, overtime represents a significant income opportunity. A $20/hour worker earns $30/hour for overtime—50% more for each additional hour. Understanding overtime calculations helps workers evaluate whether extra shifts are worth the time and helps employers budget for labor costs accurately.

The calculator handles various overtime structures, from standard federal rules to state-specific regulations.

Federal Overtime Rules

The Fair Labor Standards Act (FLSA) establishes baseline overtime requirements:

Overtime threshold: 40 hours per workweek Overtime rate: 1.5× regular rate (time and a half) Coverage: Non-exempt employees (typically hourly workers)

For a $20/hour employee working 50 hours:

• Regular pay: 40 hours × $20 = $800
• Overtime pay: 10 hours × $30 = $300
• Total: $1,100

The calculator applies this standard formula while allowing for variations.

Who Qualifies for Overtime

The FLSA divides employees into exempt and non-exempt categories:

Non-exempt employees: Generally entitled to overtime. Typically includes hourly workers and lower-paid salaried employees.

Exempt employees: Not entitled to overtime. Must meet salary thresholds (currently $684/week minimum) and perform executive, administrative, professional, or certain computer/sales roles.

Misclassification is common—some employers incorrectly classify workers as exempt to avoid overtime. Job duties, not just job titles, determine status.

State Overtime Rules

Some states have stricter overtime requirements:

California: Overtime after 8 hours in a day (not just 40/week), and double-time after 12 hours. Seventh consecutive day has special rules.

Alaska: Daily overtime after 8 hours.

Nevada: Daily overtime after 8 hours for those earning less than 1.5× minimum wage.

Other states follow federal rules exclusively.

The calculator can apply state-specific rules when selected.

Calculating the Regular Rate

Overtime rate is based on "regular rate," which may differ from base hourly rate if you receive other compensation:

If your base is $20/hour but you receive a $100 weekly production bonus, your regular rate for a 45-hour week is: ($800 base + $100 bonus) / 45 hours = $20/hour regular rate Overtime premium: 5 hours × ($20 × 0.5) = $50 Total bonus overtime: Base calculation adjusts the premium

The calculator can incorporate additional compensation when computing the regular rate.

Workweek Definition

Overtime is calculated per workweek—a fixed, recurring 168-hour period. Hours don't carry between weeks. Working 30 hours one week and 50 the next means only 10 overtime hours total, not 20.

Employers define workweek start (e.g., Sunday midnight). This definition cannot change to avoid overtime obligations.

The calculator tracks hours within workweeks appropriately.

Overtime vs. Regular Hours Decision

Is overtime worth it? Consider:

Financial benefit: 50% premium makes overtime attractive for income. 10 overtime hours at $30/hour earns as much as 15 regular hours.

Tax impact: Overtime is taxed at your marginal rate. You keep 65-80% depending on bracket—still worthwhile but less than it appears.

Energy and time cost: More work means less personal time. Excessive overtime can affect health, relationships, and job performance.

Alternative uses: Could you earn more per hour elsewhere (side gig, freelance)? Sometimes regular-rate alternatives beat overtime.

The calculator shows gross earnings; factor in personal considerations for full evaluation.

Salaried Non-Exempt Workers

Some salaried workers are still entitled to overtime. For these employees, calculate regular hourly rate first:

Fixed salary for fixed hours: Divide weekly salary by expected hours.

• $1,000 weekly salary for 45-hour workweek = $22.22/hour
• Overtime owed: 5 hours × $33.33 = $166.67

Fluctuating workweek method: Some employers use alternative calculations for salaried non-exempt workers with varying hours.

Double-Time Provisions

Some situations trigger double-time (2× regular rate):

California: Hours over 12 in a day; first 8 hours on seventh consecutive workday Union contracts: May specify double-time triggers Voluntary employer policies: Some offer double-time for holidays or extreme hours

The calculator handles double-time when applicable.

Compensatory Time

Public sector employers can sometimes offer comp time instead of overtime pay—1.5 hours of paid time off for each overtime hour worked. Private employers generally must pay overtime in cash.

Tracking and Documentation

Accurate overtime requires accurate time tracking. Keep personal records of hours worked—clock-in times, break lengths, clock-out times. This protects against errors or disputes.

The calculator can help verify whether paychecks accurately reflect hours worked.

Using the Calculator

Enter your regular hourly rate, hours worked in the week, and any applicable overtime rules (federal standard or state-specific).

The calculator shows:

• Regular hours and pay
• Overtime hours and pay (at 1.5×)
• Double-time hours and pay (if applicable)
• Total gross earnings

Model different scenarios: What if you work 5 extra hours? What's the break-even point where overtime income matches some target?

Compare to alternatives: How many regular hours elsewhere would match your overtime earnings?

Overtime pay compensates workers at premium rates for extra effort—a simple concept with real complexity in application. The calculator cuts through that complexity, showing exactly how additional hours translate to additional earnings. Know what your time is worth at overtime rates, and make informed decisions about when extra work makes sense.
