Overtime Calculator - Free Online Tool

Calculate your overtime pay, total earnings, and annual projections instantly

Whether you're an hourly worker clocking extra hours or a manager reviewing payroll costs, knowing exactly how much overtime pay you've earned — or owe — is essential. Our Overtime Calculator gives you an instant, accurate breakdown of your regular pay, overtime pay, and total earnings in seconds. Overtime pay in the United States is governed primarily by the Fair Labor Standards Act (FLSA), which requires non-exempt employees to receive at least 1.5 times their regular rate of pay for all hours worked beyond 40 in a single workweek. Some states go further — California, for instance, requires 1.5x pay for hours worked beyond 8 in a single day, and 2.0x (double-time) for hours beyond 12 in a day or for all hours on a 7th consecutive workday. This calculator covers every scenario: standard FLSA weekly overtime at 1.5x, custom multipliers (2.0x double-time, 2.5x, 3.0x triple-time, or any value you choose), and our unique two-tier California-style overtime mode where the first batch of overtime hours attracts a lower multiplier and additional hours step up to double-time. Beyond the pay period figure, you'll see annual projections scaled to your chosen pay period — whether you're paid weekly (52 periods), bi-weekly (26), semi-monthly (24), or monthly (12). The blended average hourly rate shows you what you effectively earn across all hours worked, and the overtime-as-a-percentage figure helps you understand how much of your total compensation comes from overtime. If you don't know your hourly rate, simply switch to Salary Mode. Enter your annual, monthly, or weekly salary, and the calculator automatically derives your hourly rate using your standard work hours per period. This is useful for salaried non-exempt employees who may be entitled to overtime under the FLSA despite receiving a fixed salary. The visual donut chart gives you an at-a-glance split between regular pay and overtime pay, while the stacked bar chart reinforces those proportions. The earnings breakdown table puts per-period and annual figures side by side, making it easy to see the full financial impact of working extra hours. You can also export all results to a CSV file or print a clean, formatted summary. Overtimes rates matter beyond just the legal minimum. Many employers offer premium pay rates — particularly for weekend work, holiday shifts, or split shifts — that exceed what the law requires. Our custom multiplier option lets you plug in any rate your employer offers, from 1.25x to 4.0x or beyond. Using this calculator helps workers verify their paystubs, negotiate overtime arrangements, and plan their finances when they know extra hours are coming. For employers and HR professionals, it's a quick sanity check on payroll calculations before processing pay runs.

Understanding Overtime Pay

What Is Overtime Pay?

Overtime pay is additional compensation paid to employees who work beyond a standard threshold of hours in a given period. In the United States, the Fair Labor Standards Act (FLSA) sets the federal standard at 1.5 times the regular rate of pay for all hours worked over 40 in a workweek. This is commonly known as 'time and a half.' Not all workers are entitled to overtime — exempt employees, including many managerial, executive, professional, and administrative roles earning above $684 per week, are excluded from FLSA overtime protections. However, non-exempt hourly and salaried workers who fall below the exempt salary threshold are entitled to overtime. State laws may provide stronger protections than federal law, including daily overtime thresholds and double-time requirements.

How Is Overtime Pay Calculated?

The core overtime formula is straightforward: Overtime Hourly Rate = Regular Hourly Rate × Overtime Multiplier. Then Overtime Pay = Overtime Hours × Overtime Hourly Rate. Regular Pay = Regular Hours × Regular Hourly Rate. Total Pay = Regular Pay + Overtime Pay. For example, if you earn $20/hour, work 40 regular hours plus 10 overtime hours at 1.5x, your overtime rate is $30/hour, your regular pay is $800, overtime pay is $300, and total pay is $1,100. Annual projections multiply the per-period figures by the number of pay periods per year: 52 for weekly, 26 for bi-weekly, 24 for semi-monthly, and 12 for monthly. The blended average hourly rate divides total pay by total hours worked.

Why Does Overtime Pay Matter?

Overtime pay has a significant impact on total annual earnings. A worker earning $20/hour who works just 5 overtime hours per week at 1.5x will earn an additional $7,800 per year compared to working only 40 hours. For employers, unplanned overtime can substantially increase labor costs — the same extra hours cost 50% more per unit of work. Understanding overtime calculations helps employees verify their paystubs for accuracy, negotiate work schedules, and plan personal budgets around known high-overtime periods. For HR and payroll teams, accurate overtime calculations are essential for legal compliance and preventing costly wage disputes or Department of Labor audits.

Limitations and Considerations

This calculator uses pre-tax gross pay figures. It does not account for income taxes, Social Security, Medicare (FICA), state income taxes, or other deductions, so your actual take-home pay will be lower than the figures shown. The calculator also does not account for all FLSA overtime exemptions — whether you are actually entitled to overtime pay depends on your job duties, salary level, and employer classification, which may require legal advice. State-specific overtime laws vary: California's daily overtime rules, Alaska's daily threshold, and various state-specific exemptions are not automatically applied. Always consult your employer's HR department or a qualified employment attorney if you believe your overtime has been miscalculated.

Key Formulas

Overtime Hourly Rate

OT Rate = Regular Hourly Rate × Multiplier

Applies the overtime multiplier (typically 1.5× for time-and-a-half) to your base hourly rate to determine the premium rate for extra hours.

Double Time Rate

Double Time = Regular Hourly Rate × 2.0

Used in California for hours beyond 12 in a day or on a 7th consecutive workday, and by some union contracts for holidays.

Weekly Overtime Pay

OT Pay = Hours Over 40 × OT Rate

Under FLSA rules, all hours worked beyond 40 in a workweek are paid at the overtime rate. Multiply excess hours by the OT rate.

Total Weekly Pay

Total = (Regular Hours × Regular Rate) + (OT Hours × OT Rate)

Combines standard earnings and overtime earnings for the full gross pay in a single pay period.

Worked Examples

Weekly Pay with 48 Hours at $22/hr (FLSA)

Regular hourly rate: $22.00, hours worked: 48 in one workweek, FLSA standard 1.5× overtime.

Regular hours = 40, overtime hours = 48 − 40 = 8

Regular pay = 40 × $22.00 = $880.00

OT rate = $22.00 × 1.5 = $33.00

OT pay = 8 × $33.00 = $264.00

Total weekly pay = $880.00 + $264.00 = $1,144.00

Blended hourly rate = $1,144.00 ÷ 48 = $23.83

Working 48 hours at $22/hr produces $1,144 in gross weekly pay, with overtime adding $264 (23% of total). Annualized: $59,488.

California Daily Overtime with 10-Hour Days

Hourly rate: $25.00, works 10 hours/day for 5 days/week. California daily OT rules apply.

Regular hours per day = 8, daily OT hours = 10 − 8 = 2

Daily regular pay = 8 × $25.00 = $200.00

Daily OT pay = 2 × ($25.00 × 1.5) = 2 × $37.50 = $75.00

Daily total = $200.00 + $75.00 = $275.00

Weekly total = $275.00 × 5 = $1,375.00

Weekly OT pay = $75.00 × 5 = $375.00

Under California daily OT rules, five 10-hour days at $25/hr yields $1,375/week — $375 more than the $1,000 base pay with no overtime.

Two-Tier Overtime (California 12+ Hour Day)

Hourly rate: $20.00, works 14 hours in a single day under California rules (1.5× for hours 9-12, 2.0× for hours 13+).

Regular hours = 8, Tier 1 OT (hrs 9-12) = 4, Tier 2 OT (hrs 13-14) = 2

Regular pay = 8 × $20.00 = $160.00

Tier 1 OT = 4 × ($20.00 × 1.5) = 4 × $30.00 = $120.00

Tier 2 OT = 2 × ($20.00 × 2.0) = 2 × $40.00 = $80.00

Total daily pay = $160.00 + $120.00 + $80.00 = $360.00

A 14-hour day under California two-tier rules earns $360 — $200 more than 8 hours of regular pay. The blended rate is $25.71/hr.

Frequently Asked Questions

What is the standard overtime rate in the US?

Under the federal Fair Labor Standards Act (FLSA), non-exempt employees must receive at least 1.5 times their regular rate of pay — commonly called 'time and a half' — for all hours worked over 40 in a single workweek. This is the national minimum. Many states have additional requirements: California mandates 1.5x for hours over 8 in a single day and 2.0x (double-time) for hours over 12 in a day or for all hours on a 7th consecutive workday in a workweek. Some employers voluntarily offer higher rates or premium pay for weekend and holiday shifts, though no federal law requires it.

How do I calculate overtime pay for a salaried employee?

For a non-exempt salaried employee, you first convert the salary to an hourly rate. Divide the weekly salary by the number of hours the salary is intended to compensate. For example, an employee earning $600 per week for 40 hours has a regular rate of $15/hour. Their overtime rate would be $22.50/hour (1.5 × $15). If they work 45 hours in a week, they earn $600 regular pay plus $112.50 overtime pay ($22.50 × 5 hours) = $712.50. Use our Salary Conversion mode to have this calculation done for you automatically from annual, monthly, or weekly salary figures.

What is the difference between daily and weekly overtime?

Weekly overtime (FLSA standard) is triggered only when an employee works more than 40 hours in a workweek, regardless of how many hours they work on any individual day. Daily overtime, used in California and some other states, is triggered when an employee works more than 8 hours in a single workday, even if their total weekly hours are under 40. Under California law, an employee working 9 hours on Monday and 31 hours across the rest of the week (total 40 hours) would be owed 1 hour of overtime pay for Monday under daily overtime rules, even though no federal overtime is triggered. Use the two-tier mode to model California-style daily overtime scenarios.

Are all employees entitled to overtime pay?

No. The FLSA distinguishes between 'exempt' and 'non-exempt' employees. Non-exempt workers — most hourly employees and salaried employees earning below $684 per week (as of 2020) — are entitled to overtime pay. Exempt employees are excluded from FLSA overtime protections. Exempt categories include executive, administrative, and professional employees who primarily perform managerial, supervisory, or specialized intellectual work AND earn at least $684/week. Outside sales employees and certain computer professionals also have specific exemptions. State laws may set higher salary thresholds for exemption. Determining whether you are exempt often requires reviewing your actual job duties, not just your job title.

Does overtime pay affect my annual salary significantly?

Yes, overtime can have a substantial effect on annual earnings. Consider an employee earning $20/hour with 40 regular hours per week. Working just 5 overtime hours per week at 1.5x adds $30/hour × 5 hours × 52 weeks = $7,800 per year, an increase of 18.75% over the base annual salary of $41,600. Working 10 overtime hours per week adds $15,600 annually. The impact grows further with higher base rates or higher multipliers. Our calculator shows both per-period and annual projections side by side, and the average blended hourly rate shows you what you effectively earn across all hours — which is always higher than your base rate when overtime is involved.

Can I use a custom overtime multiplier?

Absolutely. While 1.5× (time and a half) is the FLSA minimum and 2.0× (double-time) is common in certain states and union contracts, many employers offer other rates. Some offer 1.25× for evening shifts, 1.75× for weekend work, or 3.0× for holiday shifts. Our calculator lets you select from 1.5×, 2.0×, 2.5×, and 3.0× presets, or enter any custom multiplier you choose. In two-tier mode, you can independently set a Tier 1 and Tier 2 multiplier with a custom hour threshold, replicating virtually any overtime structure your employer uses.
