Worked Example

Here's a step-by-step breakdown using a standard workweek. Follow each step to understand exactly how the calculator arrives at your total pay.

Scenario
Hourly Wage$20.00
Regular Hours40 hrs
Overtime Hours5 hrs
01
Calculate Regular Pay
$20.00 × 40 hours
= $800.00

Regular pay is your hourly wage multiplied by the standard hours you worked in the week — typically 40 hours for a full-time employee.

02
Determine the Overtime Rate
$20.00 × 1.5
= $30.00 / hour

Under the U.S. Fair Labor Standards Act (FLSA), overtime hours must be paid at a minimum of 1.5× your regular hourly rate. This is the origin of the phrase "time and a half."

03
Calculate Overtime Pay
$30.00 × 5 hours
= $150.00

Multiply your overtime rate by the number of overtime hours worked to get your total overtime pay for the week.

04
Total Weekly Gross Pay
$800.00 + $150.00
= $950.00

Add regular pay and overtime pay together for your gross weekly earnings. This is your income before income tax withholding, Social Security, Medicare, or any other deductions.

How Overtime Pay Works

U.S. overtime pay is governed by the Fair Labor Standards Act (FLSA). Understanding the formulas helps you verify your paycheck and make informed scheduling decisions.

Regular Pay
Regular Pay = Hourly Wage × Regular Hours

Your base weekly earnings for standard hours worked. Most salaried-equivalent hourly workers are scheduled for 40 hours before overtime thresholds apply, though some industries or contracts set different limits.

Overtime Rate
Overtime Rate = Hourly Wage × 1.5

Federal law sets the minimum overtime rate at 1.5× the regular rate for hours over 40 per workweek. Some states — like California — require overtime after 8 hours in a single day, and some employers voluntarily pay 2× for Sundays or holidays.

Overtime Pay
Overtime Pay = Overtime Rate × Overtime Hours

Your overtime earnings are calculated separately and then added to your regular pay. This makes the premium visible and easy to verify against a pay stub.

Total Weekly Pay
Total Pay = Regular Pay + Overtime Pay (+ Double-Time Pay if applicable)

Your gross weekly pay before taxes. To model your net take-home pay, pair this with the 1099 vs W-2 take-home calculator or estimate quarterly tax obligations with the quarterly tax calculator.

When do people use an overtime calculator? Workers use this tool when reviewing a weekly paycheck, planning how many extra shifts to take, or negotiating a wage increase with a new employer. Payroll managers and small business owners use it to estimate labor costs before approving extended shifts. If your income is primarily self-employed, the freelance income calculator gives you a more accurate annual estimate that accounts for self-employment tax.

Common Overtime Situations

An overtime pay calculator is useful in more situations than most people realize. Here are the most frequent real-world use cases.

Estimating Earnings After Extra Shifts

The most common use. If you picked up extra shifts or stayed late this week, plug in your hours to see what you'll earn before payroll runs. Workers in healthcare, retail, manufacturing, and logistics use this regularly to plan budgets and track earnings week to week.

🧾

Verifying a Paycheck

If your paycheck amount doesn't look right, running the numbers yourself is the quickest way to catch a payroll error. Calculate what you should have earned, compare it to your pay stub line by line, and flag discrepancies with your HR or payroll department. Overtime miscalculations happen more often than most workers expect.

📅

Planning a Work Schedule Around OT

Some workers deliberately structure hours to maximize overtime earnings. Use the calculator to model different combinations — 44 hours vs. 48 hours, for example — and compare the take-home impact. For payroll cycle timing, see Payroll Date Checker to understand when those earnings will actually hit your account.

💼

Estimating Payroll Costs for Employers

Small business owners and managers use overtime calculators to estimate labor costs before approving extended hours. If you're heading into a busy period and need staff beyond 40 hours per week, this gives you a fast gross payroll estimate per employee before running full payroll calculations.

📊

Comparing Hourly + OT vs. Salary Offers

Deciding between an hourly job with regular overtime and a salaried role requires comparing total annual compensation, not just base rates. Combine this calculator with the hourly to salary converter and the total compensation calculator to see which offer actually pays more over a full year.

📈

Tax Planning for High-OT Periods

Heavy overtime weeks can temporarily push your withholding into a higher bracket. If you're consistently working significant overtime, it's worth estimating how much of that additional gross income will go toward taxes. Tools like a freelance income calculator or paycheck comparison calculator can help you plan for how extra earnings fit into your overall income picture.

Frequently Asked Questions

Common questions about overtime pay rules, eligibility, and calculation methods.

Under the federal Fair Labor Standards Act (FLSA), overtime applies to any hours worked beyond 40 in a single workweek for non-exempt employees. The minimum overtime rate is 1.5× the employee's regular rate of pay. Some states have stricter rules — California, for example, requires overtime for hours beyond 8 in a single workday, regardless of the weekly total. Overtime does not automatically apply to all workers; exempt employees (typically salaried workers above a certain income threshold in executive, administrative, or professional roles) are not entitled to FLSA overtime.
Time-and-a-half (1.5×) is the federal minimum, but it is not always the actual rate. Many employers, union contracts, or state laws require higher overtime rates. Double-time (2×) is common in California for hours beyond 12 in a single day and for all hours on the seventh consecutive day of work in a workweek. Some employers also voluntarily offer double-time for holidays or Sundays. This calculator supports both time-and-a-half and double-time — use the toggle to include double-time hours in your calculation.
It depends on whether the employee is classified as exempt or non-exempt under the FLSA. Salaried employees earning above the federal salary threshold (currently $684/week as of 2024) who work in executive, administrative, or professional capacities are typically exempt and do not receive overtime. However, salaried non-exempt employees — those earning below the threshold or in certain job categories — are still entitled to overtime for hours over 40. If you're unsure of your classification, your HR department or the Department of Labor's website can clarify your status.
For a standard hourly worker, overtime is calculated in three steps: (1) multiply your hourly rate by 1.5 to get your overtime rate, (2) multiply that overtime rate by the number of overtime hours worked, and (3) add your overtime pay to your regular pay for the total. Example: At $18/hr, your overtime rate is $27/hr. If you work 43 hours in a week, your regular pay is $18 × 40 = $720, your overtime pay is $27 × 3 = $81, and your total gross pay is $801. This calculator handles all three steps automatically.
Overtime pay is taxed as ordinary income — there is no special tax rate for it. However, earning a higher gross income in a given pay period may result in higher withholding for that paycheck, since withholding is often calculated as if you'll earn that amount every pay period. This doesn't mean you'll owe more tax annually — your actual liability is based on your total annual income. If you're working significant overtime regularly and want to estimate your quarterly obligations, the quarterly tax calculator can help you plan ahead.
Overtime (time-and-a-half) is 1.5× your regular hourly rate and applies to hours beyond 40 per week under federal law. Double-time is 2× your regular hourly rate and is not required by federal law — it applies in specific situations defined by state law or employer policy. In California, double-time kicks in after 12 hours in a single day or on the seventh consecutive workday in a week. Some companies also offer double-time voluntarily for holidays or emergency call-ins. This calculator supports both rates — enable the double-time toggle to add those hours to your calculation.

Example Overtime Pay Calculation

This calculator estimates overtime pay using the most common overtime rule: time-and-a-half (1.5× the hourly rate).

Example:

Calculation:

$20 × 1.5 × 10 = $300 overtime pay

This means a worker earning $20 per hour would receive an additional $300 in overtime earnings for 10 overtime hours.

Overtime Pay Formula

Overtime pay is calculated using the following formula:

Overtime Pay = Hourly Rate × Overtime Multiplier × Overtime Hours

The overtime multiplier depends on employer policy or labor regulations.

This calculator allows you to estimate how much additional pay is earned when overtime hours are worked.

What This Calculator Does

This calculator estimates regular pay, overtime pay, and total weekly earnings based on an hourly wage, regular hours, and overtime hours worked under a standard time-and-a-half overtime model.

Calculation Methodology

This calculator estimates overtime pay using a simple step-by-step process.

  1. The calculator identifies the employee's regular hourly wage.
  2. The overtime rate is calculated as 1.5 times the regular hourly wage (time-and-a-half).
  3. The overtime rate is multiplied by the number of overtime hours worked.

The result shows the estimated overtime earnings based on the entered wage and overtime hours.

This calculator provides an estimate for planning purposes and does not account for specific employer policies, collective agreements, or regional labor regulations.
