Overtime Pay Calculator – Calculate Time and a Half Instantly

Calculating extra hours on your paycheck requires knowing your exact base rate and local laws. This overtime pay calculator instantly handles the math based on your state-specific rules. The guide below explains the federal regulations and formulas that determine your final payout.

What Is Overtime Pay?

Overtime pay is the additional compensation paid to employees for hours worked beyond their standard workweek, typically exceeding 40 hours. Overtime is usually calculated at a premium rate — most commonly "time and a half" (1.5× the base pay), ensuring fair labor practices and protecting your workplace rights.

Under the Fair Labor Standards Act (FLSA), companies must pay 1.5 times your regular hourly rate for any hours worked beyond 40 in a standard workweek.

Overtime Pay Rates Explained

Your exact overtime pay rate depends on your job, state laws, and union contracts. Understanding your overtime multiplier and hourly wage multiplier ensures proper payroll compliance.

Standard Overtime — 1.5× Multiplier

Applies to all hours worked over 40 in a workweek for most non-exempt employees across the US under federal law.

Double Time — 2.0× Multiplier

Applies to hours over 12 in a single day in select states like California. Most common for factory and heavy shift workers qualifying for double time pay.

Overtime Pay Formula

Regular Hourly Rate × 1.5 × Overtime Hours = Overtime Pay

What is time and a half on 20 dollars an hour? $20 × 1.5 = $30 per overtime hour. The overtime pay formula for salaried employees works similarly — divide your weekly salary by 40 to find your base rate first.

Overtime Pay Calculation Examples

Example 1 – Retail Worker ($18.50/hr, 48 hours this week)

Regular pay: $18.50 × 40 = $740. Time and a half rate: $18.50 × 1.5 = $27.75. Overtime: $27.75 × 8 = $222. Gross weekly pay: $962.

Example 2 – Factory Worker with Double Time (California)

Worker earning $25/hr, 14-hour shift: First 8 hrs = $200. Hours 9–12 at 1.5× = $150. Hours 13–14 at 2× multiplier = $100. Total daily pay: $450.

Who Is Exempt from Overtime Pay?

Not everyone qualifies as a non-exempt employee. Exempt categories include executives, administrative professionals, IT specialists, outside sales reps, and professionals with advanced degrees. These workers must also earn above the $684/week threshold to be classified as exempt.

Frequently Asked Questions

How is overtime calculated for part-time workers? +

An overtime pay calculator for part-time workers uses the same 40-hour rule. Part-time staff only get overtime once they cross 40 hours in a single workweek. How many hours before overtime kicks in? Always 40, regardless of part-time status.

Is overtime pay taxed differently? +

No. The IRS taxes overtime pay at the same rate as standard income. Higher earnings may push your paycheck into a higher withholding bracket for that pay period, but you will get any overpaid taxes back when you file your annual return.

What is the overtime pay formula for salaried employees? +

Divide your annual salary by 52 to get your weekly pay. Divide that by 40 to find your hourly equivalent rate. Multiply by 1.5 to get your overtime rate for any hours worked over 40.

Is overtime required by federal law? +

Yes. The Fair Labor Standards Act (FLSA) requires 1.5× pay for hours over 40 per week for most non-exempt employees. States like California and Alaska have additional daily overtime rules.

What is California's overtime rule? +

California requires 1.5× pay after 8 hours/day and double time pay (2×) after 12 hours/day, plus the standard weekly 40-hour rule — making it one of the strictest states for overtime pay compliance.

What is time and a half on $20 an hour? +

Time and a half on $20 an hour is $30 per overtime hour ($20 × 1.5). For 5 overtime hours, your overtime wages total $150 on top of your regular gross weekly pay.
