Introduction

The Overtime Hours Calculator shows how much extra pay you earn for working extra hours. Enter your pay rate, your regular hours, and your overtime hours. You get back your regular pay, your overtime pay, and your total pay.

Your pay rate can be per hour, day, week, month, or year. If it is not hourly, the tool turns it into an hourly rate first. You also pick your overtime rate: time and a half (1.5×), double time (2×), triple time (3×), your own multiplier, or a flat hourly rate.

There are two overtime tiers, so you can mix rates. For example, pay the first 5 extra hours at 1.5× and the next 5 at 2×. If you only need one tier, set the Tier 2 hours to 0.

You can also set the weekly overtime limit, which is 40 hours in most places. The tool warns you if your regular hours go past that limit. Results include a step-by-step math breakdown and two charts, so you can check the numbers and see where your money comes from.

How to use our Overtime Hours Calculator

Enter your pay rate, your regular hours, and your overtime hours. The overtime calculator returns your regular pay, your overtime pay, your total hours, and your total pay, plus a step-by-step breakdown and charts.

Currency Symbol: Pick the money sign you want to see in your results, like $, €, £, ₹, or ¥. Choose "None" to show numbers only.

Pay Rate Amount: Type your base pay before overtime. This is the pay you earn for normal hours.

Pay Rate Interval: Choose if that pay is per hour, day, week, month, or year. The tool changes it into an hourly rate for you.

Regular Hours Worked: Type the normal hours you worked in this pay period. Do not count overtime hours here.

Hours Per Standard Day: Type how many hours are in one full work day, like 8. This turns daily, weekly, monthly, or yearly pay into an hourly rate.

Weekly Overtime Threshold: Type the number of weekly hours after which overtime starts. Most jobs use 40, but you can change it.

Overtime Hours (Tier 1): Type how many overtime hours you worked at your first overtime rate.

Overtime Rate Type (Tier 1): Pick the pay rate for those hours: 1.5× (time and a half), 2× (double time), 3× (triple time), your own multiplier, or a flat hourly rate. If you pick a custom choice, a new box appears so you can type the multiplier or the flat rate.

Overtime Hours (Tier 2): Type extra overtime hours paid at a second, higher rate. Leave it at 0 if you do not have any.

Overtime Rate Type (Tier 2): Pick the pay rate for those second-tier hours, the same way as Tier 1. Custom picks open a box for your multiplier or flat hourly rate.

What Is Overtime Pay?

Overtime pay is extra money you earn for working more hours than your normal schedule. In most jobs, the extra hours are paid at a higher rate than your usual pay. So if you stay late or pick up a weekend shift, each of those hours is worth more than a regular hour.

How Overtime Hours Are Counted

Most workers earn overtime after 40 hours in one workweek. That 40-hour mark is called the overtime threshold. Some contracts, unions, or countries use a lower number, like 35 or 38 hours. A few places also count overtime by the day, such as any hours past 8 in one shift.

Hours below the threshold are regular hours. Hours above it are overtime hours.

Common Overtime Rates

Overtime is usually paid as a multiple of your normal hourly pay:

  • Time and a half (1.5×): the most common rate. A $20 hour becomes $30.
  • Double time (2×): often used for holidays, Sundays, or very long shifts. A $20 hour becomes $40.
  • Triple time (3×): rare, but used in some union deals for major holidays.
  • Flat rate: some jobs pay a set dollar amount per overtime hour instead of a multiple.

Many workers hit more than one rate in the same week. For example, the first 5 extra hours may pay 1.5× and any hours after that may pay 2×. That is why overtime is often split into tiers.

The Basic Overtime Formula

The math is simple once you know your hourly rate:

  • Regular pay = regular hours × hourly rate
  • Overtime rate = hourly rate × multiplier
  • Overtime pay = overtime hours × overtime rate
  • Total pay = regular pay + overtime pay

If You Are Not Paid By The Hour

Salaried and daily-paid workers still need an hourly number before overtime can be worked out. To find it, spread the pay over the hours it covers:

  • Daily pay: divide by the hours in a standard day (often 8).
  • Weekly pay: divide by the hours in a standard week (often 40).
  • Monthly pay: multiply by 12, then divide by 52 weeks, then by weekly hours.
  • Yearly pay: divide by 52 weeks, then by weekly hours.

Who Gets Overtime

Not every worker qualifies. In the United States, the Fair Labor Standards Act (FLSA) splits workers into two groups. Non-exempt workers must get overtime pay. Exempt workers, such as many managers and some professionals who earn above a set salary, do not. Rules change by state and by country, so check your local law and your work contract.

Things To Watch

  • Overtime is usually based on one workweek, not a two-week pay period.
  • Bonuses and shift premiums can raise the "regular rate" used for overtime in some places.
  • Paid time off, like sick days, often does not count as hours worked.
  • Overtime pay is taxed like normal pay. A bigger check can move you into higher withholding for that period, so your take-home rise may look smaller than expected.
  • Keep your own record of hours. It is the easiest way to spot a short paycheck.

Formulas used

\text{Hourly} = \frac{\text{Daily Pay}}{H_d}
Hourly rate from a weekly pay rate
\text{Hourly} = \frac{\text{Weekly Pay}}{H_d \times 5}
Hourly rate from a monthly pay rate
\text{Hourly} = \frac{\text{Monthly Pay} \times 12}{52 \times (H_d \times 5)}
Hourly rate from an annual pay rate
\text{Hourly} = \frac{\text{Annual Pay}}{52 \times (H_d \times 5)}

Frequently asked questions

How much is time and a half for $20 an hour?

It is $30 an hour. Time and a half means you multiply your normal rate by 1.5.

  • $15 × 1.5 = $22.50
  • $20 × 1.5 = $30.00
  • $25 × 1.5 = $37.50

So 6 overtime hours at $20 base pay equals 6 × $30 = $180 of overtime pay.

Is overtime taxed at a higher rate than regular pay?

No. Overtime is taxed the same way as the rest of your wages. A big check can look over-taxed because payroll systems guess you earn that much every week, so they hold back more. You usually get the extra back when you file your return.

For tax years 2025 through 2028, many US workers can also deduct part of their overtime premium pay on their federal return, up to $12,500 (or $25,000 for joint filers). Tax is still taken out of each paycheck.

What salary makes you exempt from overtime?

Under federal US rules you must be paid a salary of at least $684 a week, which is $35,568 a year, and do executive, administrative, or professional work. Money alone is not enough. Your job duties must match the legal test too.

Some states set a higher bar. California, New York, and Washington all require more than the federal amount, so check your state rules.

Can my boss force me to work overtime?

In the US, yes for most workers age 16 and up. Federal law sets no limit on weekly hours and lets an employer require extra shifts. Those hours still have to be paid at the overtime rate.

Union contracts, some state laws (especially for nurses and truck drivers), and many other countries do cap forced overtime.

How does overtime work in California?

California counts overtime by the day as well as by the week:

  • Over 8 hours in one day → 1.5×
  • Over 40 hours in one week → 1.5×
  • Over 12 hours in one day → 2×
  • First 8 hours on the 7th day worked in a row → 1.5×, and hours past 8 that day → 2×

The same hour is never paid twice. You get the highest rate that applies to it.

Do you get overtime if you work four 10-hour days?

Under federal law, no. That is 40 hours in the week, so no overtime is owed even though each day is long.

In states with daily overtime, like California and Alaska, the 2 extra hours each day pay 1.5× unless the workers voted in an approved 4/10 schedule.

Do you get extra pay for working on a holiday?

Federal US law does not require it. Holiday pay such as 1.5× or 2× comes from company policy or a contract, not the law. Overtime is only required once you pass 40 hours in the workweek.

Many employers still pay a holiday premium because it helps fill hard shifts.

Do bonuses change your overtime rate?

Yes, if the bonus was promised for work, like a production, attendance, or shift bonus. It gets added in before overtime is figured. Example: $20 an hour, 45 hours, plus a $100 bonus.

  • Total straight pay: (45 × $20) + $100 = $1,000
  • Regular rate: $1,000 ÷ 45 = $22.22
  • Extra half-time owed: 5 × $11.11 = $55.56

True gifts, like a surprise holiday check, do not count.

Do part-time workers get overtime pay?

Yes. Overtime depends on hours worked, not on your job title or status. If a part-time, temp, or seasonal worker passes 40 hours in one workweek, those extra hours must be paid at the overtime rate.

Working 35 hours at two jobs for the same employer can also add up past 40 hours.

What can I do if my employer does not pay my overtime?

Keep your own log of start times, end times, and breaks. Then ask payroll in writing to fix it.

If nothing changes, file a wage claim with the US Department of Labor's Wage and Hour Division or your state labor office. Claims usually cover the last 2 years of unpaid wages, or 3 years if the employer broke the rule on purpose.
