Overtime Calculator
Last updated: June 19, 2026
An overtime calculator is a payroll planning utility that computes gross earnings for employees who work hours exceeding their standard workweek limit. It applies the regular hourly wage to normal working hours and applies an overtime multiplier (typically one-point-five times the regular rate, or double time) to the extra hours. The calculator determines gross regular pay, gross overtime pay, and the combined total gross earnings for the pay period. Human resources staff and employees use this calculator to estimate total earnings and verify paycheck accuracy.
Calculate regular, overtime pay, time-and-a-half (1.5×), and double time (2×) overtime pay. Enter your hourly rate, regular hours, overtime hours, and multiplier to see regular pay, overtime pay, gross pay, and effective hourly rate.
Quick Answer
Calculate your total gross pay including overtime. Enter your regular hourly wage, regular hours, and overtime hours worked.

Gross pay only — taxes and withholdings are not modeled.
Examples
$25/hr · 40 reg + 8 OT @ 1.5×
= $1,300 gross · $26.04 effective
$18/hr · 40 reg + 12 OT @ 1.5×
= $1,044 gross · $20.08 effective
$30/hr · 40 reg + 5 OT @ 2×
= $1,500 gross · $33.33 effective
How it works
Regular pay is your hourly rate times your regular hours. Overtime pay multiplies the rate by your overtime multiplier (1.5 by default), then by your overtime hours. The two add to give gross pay.
Regular pay · rate × regular hours
Overtime pay · rate × multiplier × OT hours
Effective hourly · gross pay ÷ total hours
Federal overtime rules (FLSA)
Under the Fair Labor Standards Act (FLSA) enforced by the U.S. Department of Labor, non-exempt employees must receive overtime pay for hours worked over 40 in a single workweek. The statutory overtime rate is at least 1.5 times the regular hourly rate (time-and-a-half). Federal law calculates overtime strictly on a weekly basis, meaning daily hours do not trigger overtime unless state laws dictate otherwise.
Whether you qualify for overtime pay depends on your classification as exempt or non-exempt. Exempt employees (often salaried professional, administrative, or executive roles earning above a set threshold) are excluded from FLSA overtime protections. Non-exempt employees, including most hourly workers and certain salaried staff, are legally entitled to receive premium rates for all overtime hours worked.
Daily overtime and double time
While federal law relies solely on a weekly 40-hour limit, several states mandate daily overtime rules. For example, California requires employers to pay 1.5× the regular rate for hours worked beyond 8 in a single workday, and a double time rate of 2.0× for hours worked beyond 12 in a single workday. Because state labor regulations vary significantly, you should always consult your local state labor department for local guidelines. The calculator includes a 2× preset to make double time calculations quick and simple.
Time-and-a-half and double-time rates by wage
This reference table shows standard time-and-a-half (1.5×) and double-time (2×) premium pay rates for common hourly wages:
| Regular Rate | Time-and-a-Half (1.5×) | Double Time (2×) |
|---|---|---|
| $12.00 / hr | $18.00 / hr | $24.00 / hr |
| $15.00 / hr | $22.50 / hr | $30.00 / hr |
| $18.00 / hr | $27.00 / hr | $36.00 / hr |
| $20.00 / hr | $30.00 / hr | $40.00 / hr |
| $25.00 / hr | $37.50 / hr | $50.00 / hr |
| $30.00 / hr | $45.00 / hr | $60.00 / hr |
| $40.00 / hr | $60.00 / hr | $80.00 / hr |
Worked example: Calculating a 45-hour workweek
Let's walk through how to calculate gross pay and the effective hourly rate for an hourly employee earning $20.00 per hour who works 45 hours in a single workweek:
Step 1: Calculate regular earnings
For the standard first 40 hours of work, pay is computed at the base rate:40 hours × $20.00/hr = $800.00
Step 2: Determine the overtime premium rate
Under standard time-and-a-half (1.5×), the overtime hourly rate is:$20.00 × 1.5 = $30.00 / hr
Step 3: Calculate overtime earnings
The remaining 5 hours worked beyond the 40-hour limit are paid at the overtime rate:5 hours × $30.00/hr = $150.00
Step 4: Sum the components for total gross pay
Add regular pay and overtime pay together to get the weekly gross total:$800.00 + $150.00 = $950.00
Step 5: Compute the effective hourly rate
Divide your total gross earnings by the total hours worked:$950.00 ÷ 45 hours = $21.11 / hr
This indicates that working overtime boosted your average hourly rate by $1.11 over your regular base pay.
Common mistakes when calculating overtime pay
- Applying the overtime multiplier to all hours: Multiplying your entire weekly hours by 1.5× instead of applying it strictly to the hours worked beyond 40.
- Assuming salaried workers are never eligible for overtime: Under FLSA rules, salary status alone does not eliminate overtime. Only employees meeting specific exemption criteria (often executive, administrative, or professional duties earning above statutory limits) are exempt; salaried non-exempt workers are still legally owed overtime.
- Ignoring state-level daily overtime rules: Computing weekly hours only and overlooking mandatory daily overtime or double-time laws enforced in states like California, which can lead to unpaid wages.

Frequently asked questions
Under U.S. federal law (FLSA), most non-exempt employees get 1.5× their regular rate for hours beyond 40 in a workweek — commonly called "time and a half." Some states and employers use 2× ("double time") for Sundays, holidays, or hours beyond 12 in a day. Set the multiplier to match your situation.
No — this calculator gives you gross pay only. Withholdings (federal, state, FICA) reduce take-home pay and depend on your specific filing situation. Use a paycheck calculator for net pay.
Federal law uses a 40-hour weekly threshold. Some states (California, Alaska, Nevada, others) also count overtime daily, typically beyond 8 hours. Always check your state's labor rules and your employer's policy.
Some are, some aren't. "Exempt" salaried employees (executive, administrative, and professional roles meeting specific criteria) are not entitled to overtime under federal law. "Non-exempt" salaried employees are. Check your offer letter or HR.
Under federal FLSA rules, overtime is calculated solely on a weekly basis for hours worked over 40 in a workweek. However, some states (such as California, Nevada, Alaska, and Colorado) enforce daily overtime laws, requiring overtime pay after 8 hours in a single workday.
Double time is an overtime pay rate equal to 2.0 times an employee's regular hourly wage. It applies when mandated by state laws (such as in California for work exceeding 12 hours in a workday or after 8 hours on the seventh consecutive day of a workweek), or when offered by employers as premium pay for holidays, Sundays, or late-night shifts.
Yes, salaried employees get overtime pay if they are classified as non-exempt under the Fair Labor Standards Act (FLSA). Exempt salaried workers—typically those in executive, professional, or administrative roles earning above a specific salary threshold—are excluded from overtime requirements, but non-exempt salaried employees must be paid overtime for hours exceeding 40 in a workweek.
Yes, part-time workers are eligible for overtime pay if their total hours exceed 40 in a single workweek under the FLSA. The law does not distinguish between full-time and part-time classification for overtime eligibility; only the actual hours worked in the workweek determine whether overtime rates apply.
No, overtime pay is not taxed at a higher rate; it is subject to the same annual marginal income tax brackets as your regular wages. However, payroll software may withhold taxes at a higher rate on paycheck cycles with heavy overtime because the system projects your annual income based on that single, larger check. For tax years 2025–2028, you can estimate tax savings from the federal overtime tax exemption using the [no tax on overtime calculator](/no-tax-on-overtime-calculator).
You can figure your overtime rate by multiplying your regular hourly rate by the overtime multiplier, which is typically 1.5 for time-and-a-half or 2.0 for double time. For example, if your regular wage is $20.00 per hour, your time-and-a-half overtime rate is $20.00 × 1.5 = $30.00 per hour, and your double time rate is $20.00 × 2.0 = $40.00 per hour.
Your effective hourly rate is your total gross pay divided by the total number of hours worked during a pay period. Because overtime hours are paid at premium rates, working overtime raises your effective hourly wage above your base regular rate. For instance, if you earn $950.00 gross for working 45 hours, your effective hourly rate is $950.00 ÷ 45 = $21.11 per hour.
To calculate overtime for a salaried non-exempt employee, divide the annual salary by 2,080 hours (the standard 40-hour work year) to find the regular hourly rate, and then multiply that rate by 1.5 to determine the overtime rate. Once the rates are established, regular pay is paid for the first 40 hours of the week, and the overtime rate is applied to all hours worked beyond 40.
