Overtime Pay Calculator
Enter your hourly wage and hours worked to instantly calculate your regular pay, overtime pay, and total weekly earnings under U.S. time-and-a-half rules.
Calculate Your Overtime Pay
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.
Regular pay is your hourly wage multiplied by the standard hours you worked in the week — typically 40 hours for a full-time employee.
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."
Multiply your overtime rate by the number of overtime hours worked to get your total overtime pay for the week.
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.
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.
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.
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.
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.
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.
